i2c problem and question in TM4C

Other Parts Discussed in Thread: TM4C123GH6PM, TLV320AIC3204

hi all

i just would like to ask, currently i am writing the i2c Code for my project but when i use TM4C pinMux or even i follow the example i am still facing some error which is as below

MAP_GPIOPinConfigure(GPIO_PB2_I2C0SCL);

MAP_GPIOPinConfigure(GPIO_PB3_I2C0SDA);

the error shown as below

Description Resource Path Location Type
#20 identifier "GPIO_PB3_I2C0SDA" is undefined main.c /tester line 88 C/C++ Problem
#20 identifier "GPIO_PB2_I2C0SCL" is undefined main.c /tester line 82 C/C++ Problem

what is the meaning of undefined? is it something need to be done?

the include file as below

#include <stdint.h>
#include <stdbool.h>
#include "test.h"
#include "inc/hw_types.h"
#include "inc/hw_memmap.h"
#include "inc/hw_gpio.h"
#include "inc/hw_ints.h"
#include "inc/hw_uart.h"
#include "inc/hw_sysctl.h"
#include "inc/hw_i2c.h"
#include "driverlib/fpu.h"
#include "driverlib/systick.h"
#include "driverlib/sysctl.h"
#include "driverlib/pin_map.h"
#include "driverlib/rom_map.h"
#include "driverlib/debug.h"
#include "driverlib/interrupt.h"
#include "driverlib/gpio.h"
#include "driverlib/uart.h"
#include "driverlib/rom.h"
#include "driverlib/i2c.h"
------------------------------------------------------------------------------------------------------------------------------------------------

another question is i have saw both driverlib and sensorlib i2c configuration and setup, when i compare driver lib is easier to understand but i would like to ask since i have search through driverlib document, and i only saw that there only send a byte at one time. is there any possible to send 3 byte at a time? and any possible quote an example for sending 3 byte data using driverlib?

thank you

Hi,

If you are using the Tiva Launchpad, these defines can be found at pin_map.h and are dependent on a preprocessor symbol. So, set it at your project settings.

hi Amit

thank for the answer problem solved

just would like to ask and confirm something in the programming, i m building this i2c to communicate with the CODEC AIC3204 which will need 3 byte each command, and this uC will be act as master to send data to activate the CODEC. if i continuous to send 3 byte will the programming as below?

i need to write the i2c command like 01 44 4C am i suppose write like below?

I2CMasterSlaveAddrSet (I2C_MASTER_BASE, I2C_SLAVE_ADDRESS, 0);

I2CMasterDataPut(I2C1_BASE, 0x01);

I2CMasterControl(I2C1_BASE,I2C_MASTER_CMD_BURST_SEND_START);

while(!I2CMasterBusy(I2C1_BASE));

I2CMasterDataPut(I2C1_BASE, 0x44);

I2CMasterControl(I2C1_BASE,I2C_MASTER_CMD_BURST_SEND_CONT);

while(!I2CMasterBusy(I2C1_BASE));

I2CMasterDataPut(I2C1_BASE, 0x4C);

I2CMasterControl(I2C1_BASE,I2C_MASTER_CMD_BURST_SEND_FINISH);

while(!I2CMasterBusy(I2C1_BASE));

once complete above can i need continue another line such as 00 01 02 can be written as same as above command?

thank once again for amit and markel guidance during this few day

Hello Kelvin,

Yes, it can be done in the same manner. Suggestion would be to make a function of the above lines and then pass the data that you need to send to this function.

Amit

hi amit

thank for the answer will try sooner, as my code just started haven't completed. but one more, correct me if i have mistake, i am not sure about the i2c slave address for the tm4c123gh6pm but based on the reference on the datasheet 16.4.1 configure i2c module to tx single byte as a master, i reference it written as 0x3B, is the slave address for this case is 0x3B?

thank once again

0 Amit Ashara over 11 years ago in reply to Kelvin You

TI__Guru**** 244400 points

Hello Kelvin,

The Slave Address is as per the external device you are using and is fully programmable in the I2CMSA registers bits 7 downto 1. The 0x3B that may have been given in the example code.

Amit

hi Amit

i have tried to put all the code into the uC , based on what i have sent you, but it does not work as expected, i not sure what happen but when i slowly step over and over again by clicking F5, found that there is a message show

Can't find a source file at "C:/DriverLib/build/DriverLib.test/driverlib/sysctl.c"
Locate the file or edit the source lookup path to include its location.

what is it, is it an error?

below are the attachment show the program i written due to too long, i put in txt file

Hello Kelvin,

Looking at the error message it seems that it is not able to find the original driverlib.lib for the disassembly. You can import the driverlib.lib as a CCS project, recompile it and then use the resulting lib file in the Linker Path.

Alternatively you can add sysctl.c to the Locate File Button.

Regards

Amit

hi Amit,

do you mean like doing as same as the above pic?, if yes, i have linked my file into the project location

the above are my file directory

Hello Kelvin,

Import the driverlib as shown in the Snapshot, compile it and then use the output driverlib.lib which would be created in the workspace

hi amit

thank, the error is dissapear, 1 more question,

in the i2c devices, it mentioned that

30 00 00 mean [i2c address] [register] [data]

curious to ask i m needed to write that data to send it to the devices unfortunately i try both type also not function such as writting register and data only

I2CMasterDataPut(I2C0_MASTER_BASE, 0x00);
I2CMasterControl(I2C0_MASTER_BASE,I2C_MASTER_CMD_BURST_SEND_START);
while(!I2CMasterBusy(I2C0_MASTER_BASE));
I2CMasterDataPut(I2C0_MASTER_BASE, 0x00);
I2CMasterControl(I2C0_MASTER_BASE,I2C_MASTER_CMD_BURST_SEND_FINISH);
while(!I2CMasterBusy(I2C0_MASTER_BASE));

and write included i2c address of the devices

I2CMasterDataPut(I2C0_MASTER_BASE, 0x30);
I2CMasterControl(I2C0_MASTER_BASE,I2C_MASTER_CMD_BURST_SEND_START);
while(!I2CMasterBusy(I2C0_MASTER_BASE));
I2CMasterDataPut(I2C0_MASTER_BASE, 0x00);
I2CMasterControl(I2C0_MASTER_BASE,I2C_MASTER_CMD_BURST_SEND_CONT);
while(!I2CMasterBusy(I2C0_MASTER_BASE));

I2CMasterDataPut(I2C0_MASTER_BASE, 0x00);
I2CMasterControl(I2C0_MASTER_BASE,I2C_MASTER_CMD_BURST_SEND_FINISH);
while(!I2CMasterBusy(I2C0_MASTER_BASE));

both are not function as i aspected, in the driverlib the i2c base address is from the uC but not from the devices, same the slave address from uC, but i not sure after i have set up, included write up the program, but still failed to work. is it correct i write only send i2c data without read data from the devices?

hi amit

i have followed the reading through the post, i found out that if i include

while(!( I2CMasterBusy(I2C0_BASE) ));

the above code will keep looping non stop

while( I2CMasterBusy(I2C0_BASE) );

with the above there is no looping and continue from 1st until end,

0 Amit Ashara over 11 years ago in reply to Kelvin You

TI__Guru**** 244400 points

Hello Kelvin,

The above mentioned line is due to the higher core frequency in TM4C129. On TM4C123 you can comment it or put a SysCtlDelay(10) (the latter in case you want to migrate it to TM4C129 later)

i think i have understand on about the explaination included the code. but refer to the one u send me i found that mine have extra component which is write command, since from above code i saw that we only have send and check master busy or not, but there is a write between 1st byte and 2nd byte. is it mean i have to put in an extra command to allow it write. or proceed with the previous way i written.

thank a lot

Hello Kelvin,

The section of diagram that you have highlighted is centric to any I2C operation. This is done by the API I2CMasterSlaveAddrSet with the third parameter set to false.

hi amit

i have tried using osc scope, there is a data from SDA line, which mean the data i wanted to have, but just curious to ask, the other devices are non programmable, but need i2c to communicate with it. based on the image bi sent u, do i need to send SCL too for clock?

each time i try to use the i2c sometime it stuck at command i2cmasterbusy, i have no idea why even with dalay

there is an error which is cannot load from non-primitive location

thank

0 Amit Ashara over 11 years ago in reply to Kelvin You

TI__Guru**** 244400 points

Hello Kelvin,

SCL and SDA are both mandatory for I2C. Can you attach the final code and mark it where it get's stuck?

Regards

Amit

Hello Kelvin,

That could be the case if you halted the code in the middle of a transmission that could have caused the Slave to get stuck.

To ensure that the Master is not stuck, can you add the following code to the PortFunctionInit!!!

MAP_SysCtlPeripheralEnable(SYSCTL_PERIPH_I2C0);

with

MAP_SysCtlPeripheralDisable(SYSCTL_PERIPH_I2C0);

MAP_SysCtlPeripheralReset(SYSCTL_PERIPH_I2C0);

MAP_SysCtlPeripheralEnable(SYSCTL_PERIPH_I2C0);

Regards

Amit

hi amit

i m still stuck at the same line which i have mentioned just now

Hello Kelvin,

The debug cannot happen without knowing what slave device you have. Can you send the datasheet of the slave device,

Regards

hi Amit

below are data sheet of the devices

thank a lot

Hello Kelvin

The I2C Address of this device is 0x18 and not 0x38. This is very clearly mentioned in the data sheet and application note, unless I am missing something in the documentation

Regards

Amit

hi amit

i think i have mistake as i tot i using the slave address from uC rather than using the slave address from the device as i mentioned above

i m still having problem of the program still keep looping meaning the i2c master are busy all the time after the 1st byte been sent out

Hello Kelvin,

Can you attach a scope screenshot of what the transaction is looking as?

hi amit

below are the scope for SDA, SCL will be zero all the time

while i connect to the devices, there is noise occur and the i2c signal lost

when i try using step over in CCS, found that it stuck at i2cMasterbusy

therefore i have no idea why it stuck at i2cmasterbusy

Hello Kelvin

I2C SCL cannot be 0. Is the Pull Up on SCL and SDA there on your board.

Regards

Amit

0 Kelvin You over 11 years ago in reply to Amit Ashara

Intellectual 680 points

there is an pull up in other devices, but signal losses when it is connected to other board

0 Amit Ashara over 11 years ago in reply to Kelvin You

TI__Guru**** 244400 points

Hello Kelvin,

The Pull is needed for the bus to operate. So you should complement the pull up of the devices with an on-board pull up for the bus, so that even if you connect any new device which does not have an internal pull up, the protocol can work properly.

I hope I am able to explain it well

Regards

Amit

0 Kelvin You over 11 years ago in reply to Amit Ashara

Intellectual 680 points

which mean that, i need another pull up for the uC and another pull up for the devices?

as i saw that there are a pull up in the devices which i need to i2c but no pull up for uC,

will try out and let u know sooner

0 Amit Ashara over 11 years ago in reply to Kelvin You

TI__Guru**** 244400 points

Hello Kelvin,

No. You would need only 1 set of Pull Up for both uC and the devices. However the Pull up needs to be there on SCL and SDA

Can you draw a simple diagram of the connection between the uC and slave devices and where pull up's are present with what value. This is important as we need to understand and resolve why SCL line is always low.

Regards

Amit

hi amit

below are my own design for i2c

meanwhile on the other hand using evaluation board for the other devices as following

where the iovdd is 3.3V

0 Amit Ashara over 11 years ago in reply to Kelvin You

TI__Guru**** 244400 points

Hello Kelvin,

It is correct: As long when configured for I2C, you see both SCL and SDA during bus idle state.

In the second snapshot are the Jumpers mounted and SCL and SDA shown coming from the uC which is somewhere in the schematic. The Pad SCL and SDA shown in the right side of the picture would be some header for other devices?

Regards

Amit

the 2nd pic is come from the evaluation board of the devices itself which i have sent u the data sheet and the application note

i will try a trick which will be doing an external pull up for SDA and SCL
