TMDSRM48USB development kit interfacing with MSP430G2553

Thank you Zhaohong for your quick reply.

Can you please guide me, how to access the LIN_TX and LIN_RX pins ?
I am not able to figure out, where are these pins located ?
If possible please give links to understand the concepts.
I want to transmit the received data on DCAN1 port to UART as well as on LIN_RX and LIN_TX.
I have connected the cables from LIN_TX (RM48USB)-> RXD(MSP430G2553) & LIN_RX (RM48USB)-> TXD(MSP430G2553) to display the data on LCD interfaced to MSP430G2553.

LIN pins are not brought out to the connectors. You can setup the SCI module in the same way as the LIN module.

Thanks and regards,

Zhaohong

Dear Zhaohong

With the HALCoGen I created project. After that I disabled all drivers and has selected SCI.
The I have generated code.
In the code composer studio, I created same project with following code. I was not able to receive any characters on NHET1[13] of RM48USB.
My sys_main.c is following

/** @file sys_main.c
* @brief Application main file
* @date 15.July.2015
* @version 04.05.00
*
* This file contains an empty main function,
* which can be used for the application.

You need to configure the PINMUX module to enable SCI function on those two pins. Then you can use a scope to see if any data coming out of the tx pin. To confirm if the PINMUX is configured correctly, you can first set up the SCI pins for GIO outputs and check if writing to the SCI register (see TRM) can change the pin state.

Thanks and regards,

Hi Zhaohong

I tried to configure PINMUX module. I enabled SCITX from PINMUX module and has selected "Enable SCI driver" instead of Enable SCI2 driver.
I am using the example given in HALCoGen " example_sci_uart_9600"
The program is staying forever at while ((scilinREG->FLR & 0x4) == 4); /* wait until busy */
In the function "void sciDisplayText(sciBASE_t *sci, uint8 *text,uint32 length)"

I am not able to figure out further step.

Hi
Thanks for reply.
What should be written for sci module if sciREG is wrong ?

Hi
I have made following selections in HALCoGen in pinmux:
N2-> SCITX
W3-> SCIRX
I have also enabled only SCI driver in Driver Enable of HALCoGen
and I have modified the code to following, but stll not able to receive any character on RX pin of MSP430 connected to NHET1[13] pin of RM48.

/* USER CODE END */

you are still writing to the LIN module.

"sciSendByte(scilinREG,*text++); /* send out text */"

Thanks and regards,
