17.4.16 CANopen SDO segmented write callback
}
Remark: If the flag isr_handled was set 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 segmented write callback function is called by the CANopen handler.
The callback function allows the following actions:
Responses can be selected to be 8-byte (CANopen standard compliant) or 1-byte (faster
but not supported by all SDO clients).
// Values for CANOPEN_sdo_seg_read/write() callback 'openclose' parameter
#define CAN_SDOSEG_SEGMENT 0 // segment read/write
#define CAN_SDOSEG_OPEN 1 // channel is opened
#define CAN_SDOSEG_CLOSE 2 // channel is closed
Example call (writing a buffer):
uint8_t write_buffer[0x321];
// CANopen callback for segmented write accesses
uint32_t CANOPEN_sdo_seg_write(
{
}

{

uint16_t index, uint8_t subindex, uint8_t openclose,
uint8_t length, uint8_t *data, uint8_t *fast_resp)
static uint16_t write_ofs;
uint16_t i;
if ((index == 0x2200) && (subindex==0))
