17.4.13 CANopen SDO expedited read callback
17.4.14 CANopen SDO expedited write callback
}
The CANopen SDO expedited read callback function is called by the CANopen handler.
The callback function is called before the SDO response is generated, allowing to modify
or update the data.
Example call:
// CANopen callback for expedited read accesses
uint32_t CANOPEN_sdo_exp_read(uint16_t index, uint8_t subindex)
{
}
Remark: If the flag isr_handled was set to TRUE when initializing CANopen, this callback
function will be called by the CAN API interrupt handler and therefore will execute on the
interrupt level.
The CANopen SDO expedited write callback function is called by the CANopen handler.
The callback passes on the new data and is called before the new data has been written,
allowing to reject or condition the data.
Example call:
// CANopen callback for expedited write accesses
uint32_t CANOPEN_sdo_exp_write(uint16_t index, uint8_t subindex, uint8_t
*dat_ptr)
{
}
// If we went into bus off state, tell the application to
// re-initialize the CAN controller
if (error_info & CAN_ERROR_BOFF)
return;
// Every read of [2001h,0] increases param by one
if ((index == 0x2001) && (subindex==0))
return 0;
// Writing 0xAA55 to entry [2001h,0] unlocks writing the config table
if ((index == 0x2001) && (subindex == 0))
if (*(uint16_t *)dat_ptr == 0xAA55)
reset_can = TRUE;
param++;
{
}
else
write_config_ena = TRUE;
return(FALSE); // Reject any other value
return(TRUE);
