Hi Kalaiventhan,

There is a DCAN HAL driver in starterware. You can refer to DCAN loopback examples as a start point.

HI,

which kind of PINs to use of CAN protocol and UART protocol

1) which PIN to use
2)which port in the board

Hi Kalaiventhan,

Which UART and DCAN instance do you want to use? and also, is it TI EVM?

I need to use UART 0 , UART 1 and DCAN 1.where I will get the pins of UART and DCAN.how to configure that?

In case you are referring to TI EVM, you should look at the EVM schematics to see what all UART instances can be used. You will have to drive the corresponding IO expanders using I2C communication.
Then you should also look at the ball numbers and do the corresponding pin mux.
I would suggest you to go through starterware examples.

HI Rishabh,

can u send EVm schematics link , because i want to use all peripheral devices(UART,CAN,I2c).

thanks

Hi Kalaiventhan,

You need to contact Spectrum Digital for EVM schematics.

HI,

what we have to change in env make file at startware folder.

Hi,

Env.mk contains paths to the tool chains and various build environment variables. You need to update it for building starterware if you are not using defualt paths/ tool chains.

HI rishabh,

thanks,i need to use UART from startware examples .how to load the coding and which port i have to check

0 Rishabh Garg over 8 years ago in reply to kalaiventhan v

Hi Kalaiventhan,

There are many UART examples in starterware. On TI EVM you can test both UART1 and UART3.
You can load the code using CCS and run the binary.

HI rishabh,

thanks,i need details about tda2xx com module port marked below image (what purpose of this port ,can we take output from this port like UART 3,SPI,I2c).

Hi Kalaiventhan,

It is a connector named P9. Please search P9 in board schematics. Thanks.

HI rishabh,

thanks ,can we use UART1 and UART3 with separate function at sametime .

Hi, Kalaiventhan,

I am not sure what exactly do you mean.

For information about UART functionality, refer to the UART chapter in Technical Reference Manual:

HI,

I was execute and received data using DCAN1 protocol.we need to use RX and TX simultaneously in the same board so where we have to change in example program for RX and TX simultaneously ,any reference document for that.
