Can transmission problem on S5D9

Hello,

I want to send a can message with S5D9 board to a Pcan-usb Pro. The code is running (inspired buy CAN_HAL_DRIVER_MODULE on S7G2) but the message can't be received buy the PCAN (his green light blinking red when i send something).

I think it's because the can S5D9 Kbits/s isn't the same as PCAN Kbit/s. Indeed, " tx_flag= false" so "CAN_EVENT_TX_COMPLETE" is false too. I have 500Kbits/s on PCAN and i tought i had 500Kbit/s too on S5G9. We I initialised S5G9 i used the documentation :

bit_rate = (fcanmclk/BRP)/(Tseg1+Tseg2+SS) = (60/5)/(15+8+1). What am i doing wrong ?

Thanks you and sorry for my english.

thanks for reply
have u used timer interrupt for CAN or CAN specific interrupt?

I send two messages with bus Can. One with pulling a button and another every 100ms with a Timer

in ur microcontroller, is there any CAN specific interrupt present?

In reply to Thib:
In my case, there are SW interrupt, timer interrupt, Peripheral specific interrupt,

So I am using peripheral specific interrupt.

In ur case, peripheral specific interrupt is present or not?

I have can_callback (interrupt func for can) to check the good transmission or reception of can messages (CAN_EVENT_TX_COMPLETE, CAN_EVENT_RX_COMPLETE)

Thib,

How is your project progressing?
