STM32F303VET - issue in transmitting CAN messages I am having an issue in transmitting CAN messages, my situation is the following:There is an interrupt function for RX messages from CAN1, when a message is received, it sets a flag. The baud rate of the RX message is 10ms and they are being sent over the software PCAN. struct
{
volatile uint8_t transmit_data;
}Flags;
void can1_RxCallback()
{
Flags.transmit_data = 1;
} In the main function in the while-loop, this flag is compared, if it is high, it executes a code to transmit data over CAN-Bus.
while (1)
{
if (1 == Flags.transmit_data)
{
tx_data();
}
}
void tx_data(void)
{
//delay(1); //Non interrupt delay in ms
can_transmit(&can, CanMessObj[nr].MessageID, 0, (uint8_t *)CANTrxBuffer[nr].Data, CanMessObj[nr].Length);
Flags.transmit_data = 0; //Reset Flag
}
void can_transmit(can_Interface_t* canInterface, uint32_t Id, uint32_t ide, uint8_t data[8], uint8_t length)
{
uint32_t mailbox;
canInterface->txMsg.IDE = ide;
canIn
