S32K LIN

Hello NXP Team,

I am using S32K148 LIN master example to blink a RGB LIN Slave NCV7430.

I have created a LDF for NCV7430 & generated lin cfg files in S32DS.

I am updating signal using api's of lin_cfg.h.

However I can observe the signal is not being updated on Canoe trace window.

I am uploading LDF file and generated lin (CFG) and main.c.

Please let me know what am I missing ?

Hi @imdevendra258 ,

I tried to create an example based on the data that was sent by you. It seems all the signals have been updated correctly.

- Hardware: S32K148EVB-Q176 29644 PCB RevX1 SCH RevB

- Software version: S32SDK S32K1xx RTM v3.0.3

- S32DS: S32DS 2.2

Signals before updated:

Signal after updated:

Please recheck on your side. If the issue is still not resolved, please share with me some information about your setup(hardware, software ...).

Best regards,

Dan

Hi Dan,

Thanks for response It is resolved .I needed to do correct the clock setting for timer as I have 40MHZ external crystal on board.

However I am facing issue with blinking of RGB NCV7430.

I have sent 2 frames: 0x24 and 0x23 from LDF & however it is not blinking it.

I am uploading updated LDF created for NCV7430, main.c & generated lin cfg file, NCV7430 Datasheet,NCV7430 Demo code of arduino link

https://github.com/skpang/Teensy32_LIN-bus_NCV7430_RGB_demo .

I am transferring data as expected .I have set signal as per requirement in main.c but still it is not blinking the NCV7430 RGB led.

Do I need to send PID along with data byte frame of lin. Please let me know what am I missing here ?

Please change timer compare macro value and TIMER PRES macro value to this main.c according to last main.c file value.I have changed these two macro as I am running on different frequency and PREscale.

You can see diff I have just modified the LDF signal and those 2 macro value in main.c.

Thanks & Regards,

Devendra Mishra

Hi @imdevendra258 ,

I only can support you with issues regarding the LIN driver and can't support for debug the Demo code of arduino following your request.

Best regards,

Dan
