Other Parts Discussed in Thread: TM4C1294NCPDT, TM4C1233H6PM

Hello guys, this is my second fight with connected launchpad :)

I need to show measurments from Sensor Hub to Sharp Memory LCD Display, but first want to see any message on it. So i made steps that Markel told me on the link below:

e2e.ti.com/.../1621540

(i hope i made changes right)

changed value of tiva_ware variable to my tiva ware instal folder,

update Tivaware Installation Directory includepath,

add directories of driverlib.lib and grlib.lib files in file search path

also i copied startup file and .cmd file from example hello_world

but i still encounter the same errors

here is my project:8507.SharpLcdMemoryDisplay.rar

Hi bode,

So, that we are doing the same, don't use the SharpLcdMemoryDisplay CCS project from this link below. I encountered the same errors. I do not have the time yet to debug the errors.

e2e.ti.com/.../666073

Delete that CCS project from your CCS workspace and download and import SharpLcdTivawareDemo CCS project from the link below. Make the changes that I have suggested. The CCS project should build without errors.

github.com/.../Tiva-Sharp-LCD-Interface

At Predefined symbols add these symbols below.

PART_TM4C1294NCPDT
TARGET_IS_TM4C129_RA0

Remove this below Predefined symbol.

PART_TM4C1233H6PM

After this you need to change API's example SysCtlClockSet() and SysCtlClockGet() to API's that is for TM4C129 MCU.

Then you need to change this line below to equivalent initialization for Tiva Connected Launchpad.

GPIOPinConfigure(GPIO_PB7_SSI2TX);
GPIOPinConfigure(GPIO_PB4_SSI2CLK);

I don't have a Sharp Memory LCD Booster Pack to test this. If you encounter any more problems after my recommended changes, post it here

Hello Bode,

Seems that other forum post is marked Verified and Answered. Not sure what is the help you need. Can you list out the errors?

Hello Amit,
When i want to show data from sensor hub on sharp LCD display. And first i try to show some text on display. When i was trying to do this example e2e.ti.com/.../666073
i had errors below:
CORTEX_M4_0: GEL: Encountered a problem loading file: D:\programs\TM4C1294 Connected LaunchPad Workshop\workspace\ShanrpLcdMemoryDisplay\Debug\SharpLcdMemoryDisplay.out Could not open file

Description Resource Path Location Type

Now i build this project github.com/.../Tiva-Sharp-LCD-Interface and just for building project is okay, but i still can't see anything on display. So now i have to edit the code - have to change pin which is equivalent on Connected Launchpad
GPIOPinConfigure(GPIO_PB7_SSI2TX);
GPIOPinConfigure(GPIO_PB4_SSI2CLK);

and maybe have to change this functions
SysCtlClockSet() and SysCtlClockGet()

0 bode miller over 9 years ago in reply to Amit Ashara

Do you know which GPIO pins i have to use, because i have this errors now:
Description Resource Path Location Type
#20 identifier "GPIO_PB4_SSI2CLK" is undefined Sharp96x96.c /SharpLcdTivaWareDemo line 284 C/C++ Problem

Hello bode,

Seems that stdint and stdbool are the missing includes at the start of the C file.

Regards
Amit

0 Amit Ashara over 9 years ago in reply to bode miller

TI__Guru**** 244400 points

Hello Bode

Yes, that is because of the missing include for driverlib/pin_map.h

Regards
Amit

0 bode miller over 9 years ago in reply to Amit Ashara

Hi Amit,
I add #include "driverlib/pin_map.h" in beginning of main.c but still have same error.
In 96x96.c file already have #include "driverlib/pin_map.h"

0 Amit Ashara over 9 years ago in reply to bode miller

TI__Guru**** 244400 points

Hello Bode,

As Markel Robregado already mentioned, did you add the define PART_TM4C1294NCPDT in the predefine section.

Also please share the compilation log for the error.

Regards
Amit

0 bode miller over 9 years ago in reply to Amit Ashara

Intellectual 640 points

Yes, i changed predefine section, now it looks like this:
PART_TM4C1294NCPDT
TARGET_IS_TM4C129_RA0
"ccs"
ccs="ccs"

Where i can see compilation log?

0 Amit Ashara over 9 years ago in reply to bode miller

TI__Guru**** 244400 points

Hello Bode,

For the part TM4C1294NCPDT, PB4 does not have SSI2CLK. That is why you are getting the error. Are you sure that in the data sheet for TM4C1294NCPDT you are reading PB4 as SSI2CLK Pin?

Regards
Amit

0 bode miller over 9 years ago in reply to Amit Ashara

Intellectual 640 points

Yes, i know it is PD3 for SSI2CLK, i understand it, but what is for GPIO_PB7_SSI2TX

0 Amit Ashara over 9 years ago in reply to bode miller

TI__Guru**** 244400 points

Hello Bode

Where in the data sheet does it state that SSI2TX is PB7 pin for TM4C1294NCPDT?

Regards
Amit

0 bode miller over 9 years ago in reply to Amit Ashara

Intellectual 640 points

I can't see anywhere state SSI2TX in this document page 10 and 11 www.ti.com/.../spmu365b.pdf

0 Amit Ashara over 9 years ago in reply to bode miller

TI__Guru**** 244400 points

Hello Bode

It is called SSI2XDAT0 pin in the document. please first refer to the data sheet before checking related documents.

Now when i hold mouse on some functions in 96x96.c file i see error: can not load from non primitive location and this errors in expresions. Maybe i have to change SysCtlClockSet and SysCtlClockGet functions like Markel said, but i don't know how it have to be.

Hello bode

If a variable is declared in the function and the current scope of the PC is not in the function then you may not be able to see the variables. Either make them global or set a break point to the function, so that the scope of the CPU execution is in the function.

Amit

I changed SysCtlClockGet() to SysCtlClockFreqSet(SYSCTL_OSC_INT | SYSCTL_USE_PLL | SYSCTL_CFG_VCO_320,

TI__Guru**** 244400 points

Hello Bode,

I think you have not read my previous post. This has got nothing to do with the SysCtlClockGet/SysCtlClockSet to SysCtlClockFreqSet

"If a variable is declared in the function and the current scope of the PC is not in the function then you may not be able to see the variables. Either make them global or set a break point to the function, so that the scope of the CPU execution is in the function."

Hello Amit,
Yes i read it, but not very sure what to do. Cursor is blinking just before starting of main(void). Which variable i have to make global. To make them global i have to define them before int main(void) righ?And about breakpoints do i have to make one at start of main function and one in end of main function and then run code between this two breakpoints?
:)

0 Amit Ashara over 9 years ago in reply to bode miller

TI__Guru**** 244400 points

Hello Bode,

The PC has to be in the function where the variables have been declared and being used. You can set the Break point to the first line of the function.

Hello bode,

Since your code is not using those variables, please remove them from the expression window. Right click on the variable in the expressions window and you must see something like "remove" or "delete"

Regards
Amit

0 bode miller over 9 years ago in reply to Amit Ashara

Intellectual 640 points

Hello Amit,
I remove this variables, then go trough int main(void) with assembly step into button and on row 91-92 SysCtlClockSet(SYSCTL_SYSDIV_10 |SYSCTL_USE_PLL | SYSCTL_OSC_MAIN |
SYSCTL_XTAL_16MHZ);
I saw that my link for location of file sysctl.c is wrong, after that i change it to my Tiva ware folder\driverlib\sysctl.c
and now when i press step into button i can see stsctl.c file. May i have to make some changes there?
Thanks for attending!

bode, I have already replied here that you need to change SysCtlClockSet() API to SysCtlClockFreqSet(). Also, don't change your Tivaware folder location to \driverlib\sysctl.c.

In clockInit(void) i wrote this function SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ | SYSCTL_OSC_MAIN | SYSCTL_USE_PLL | SYSCTL_CFG_VCO_480), 120000000);
i found it in light example for senshub for configure the frequency.
Now i have arrow in begining of main(void) and when hold mouse on arrow i can see cortex_m4_0 - debug call stack

Why move the mouse on the arrow for? You must either run or step run to debug the code.

Hi Erick,

I suggest you resolve the warnings first. Also replace the SysCtlClockGet(), with the actual system clock.

0 Eric YO over 8 years ago in reply to Markel Robregado

Prodigy 80 points

Hello,

I have changed the SysCtlClockGet() to SysCtlClockFreqSet() and set it to a variable uint32_t g_ui32SysClock, so I could use it in other files. Actually not sure if I am even doing this right. At any rate, I am confused about how to clear up these warnings.

Best,

0 Amit Ashara over 8 years ago in reply to Eric YO

TI__Guru**** 244400 points

Hello Eric,

First of all the SysCtlClockFreqSet should be called only once and without any division or add operations. The returned value is the system clock frequency. You can then use whatever operation on the variable subsequently. Else your code would be not optimal

Second of all. do you have the cmd file for the linker in your project? If yes, then please share the same. if not then add one from the existing TivaWare examples.

Hello Eric

I compiled your code and it gave me the same error. As I stated earlier there is no "cmd" file included in your project when I imported the project. Please add a cmd file to the project by copying one from TivaWare and then pasting it in the Code Composer Studio project.
