Just changing over to the STM8 using STVD and Cosmic.
I have converted an existing project over to the new chip and compiler and have a clean compile of all the modules.
The Linker is complaining that
#error clnk Debug\5971.lkf:1 @svlreg missing for function f_CAN_RX_IRQHandler
I have updated the vector table in stm8_interrupt_vector.c to identify I have a Tim2 and a CAN Rx interrupts(see below). The Tim 2 interrupt handler is in a file called 5791.c and the CANRx interrupt is in the stm8s_it.c inserted in the list of interrupt handlers as shown below:
//****************************************************************************
// CAN_RX_IRQHandler
// Stores data into extern variables
// Calls CAN_RX() to parse data
//****************************************************************************
INTERRUPT_HANDLER(CAN_RX_IRQHandler, 8)
{
extern uint32_t CANMsgIde;
extern uint8_t CANMsgDLC;
extern uint8_t CANMsgData[8];
uint8_t i;
CAN_Receive(); // Get the message from the Rx FIFO
CANMsgIde = CAN_GetReceivedId(); // Get 32 bit EXTENDED IDE
CANMsgDLC = CAN_GetReceivedDLC(); // Get DLC
for(i = 0; i <8; i++)
{
CANMsgData[i] = CAN_GetReceivedData(i); // Get can msg data
}
CAN_RX(); // Lastly call CAN_RX to process
}
stm8s_it.h has the following two lines at the top:
@far @interrupt void CAN_RX_IRQHandler(void);
@far @interrupt void TIM2_UPD_OVF_IRQHandler(void);
Interrupt Vector table is as folows:
struct interrupt_vector const _vectab[] = {
{0x82, (interrupt_handler_t)_stext}, /* reset */
{0x82, NonHandledInterrupt}, /* trap */
{0x82, NonHandledInterrupt}, /* irq0 */
{0x82, NonHandledInterrupt}, /* irq1 */
{0x82, NonHandledInterrupt}, /* irq2 */
{0x82, NonHandledInterrupt}, /* irq3 */
{0x82, NonHandledInterrupt}, /* irq4 */
{0x82, NonHandledInterrupt}, /* irq5 */
{0x82, NonHandledInterrupt}, /* irq6 */
{0x82, NonHandledInterrupt}, /* irq7 */
{0x82, (interrupt_handler_t)CAN_RX_IRQHandler}, /* irq8 */
{0x82, NonHandledInterrupt}, /* irq9 */
{0x82, NonHandledInterrupt}, /* irq10 */
{0x82, NonHandledInterrupt}, /* irq11 */
{0x82, NonHandledInterrupt}, /* irq12 */
{0x82, (interrupt_handler_t)TIM2_UPD_OVF_IRQHandler}, /* irq13 */
{0x82, NonHandledInterrupt}, /* irq14 */
{0x82, NonHandledInterrupt}, /* irq15 */
{0x82, NonHandledInterrupt}, /* irq16 */
{0x82, NonHandledInterrupt}, /* irq17 */
{0x82, NonHandledInterrupt}, /* irq18 */
{0x82, NonHandledInterrupt}, /* irq19 */
{0x82, NonHandledInterrupt}, /* irq20 */
{0x82, NonHandledInterrupt}, /* irq21 */
{0x82, NonHandledInterrupt}, /* irq22 */
{0x82, NonHandledInterrupt}, /* irq23 */
{0x82, NonHandledInterrupt}, /* irq24 */
{0x82, NonHandledInterrupt}, /* irq25 */
{0x82, NonHandledInterrupt}, /* irq26 */
{0x82, NonHandledInterrupt}, /* irq27 */
{0x82, NonHandledInterrupt}, /* irq28 */
{0x82, NonHandledInterrupt}, /* irq29 */
};
I am new to this processor/compiler so I reckon I must be doing something wrong. Can anybody point me in the right direction please?
Many thanks, Bruce
