AIS2120SX sensor read data issue Hi , i am trying to read the sensor data of AIS2120x only for sensor ID type , i can see from the bus the data is transferred correctly, but i don't receive any data back from sensor rather its only 0.
i have attached the code snippet for this test, any leads will be helpful. @JHo.1
@JHo.1 and @Eleon BORLINI @CJeff.1
test 1:
CS_low();
Sensor_Write(0xD1,0x80,ubAisSensor ); // command to read address 0x0C/REG_ID_SENSOR_TYPE from AIS2120x
// according to 32 byte cmmand format
Sensor_Write(0x00,ubCrcVal,ubAisSensor );
CS_high();
Test 2:
CS_low();
Sensor_Write(0x8C,0x00,ubAisSensor ); // command to read address 0x0C/REG_ID_SENSOR_TYPE from AIS2120x
set_high();
//Sensor interface
void Sensor_Write(uint8 addr, uint8 Data,(uint8 Sensor) {
// application specific
spi_Write(addr);
delay();
spi_Write(Data);
}
//receive ISR
uint8 ubSpiStatus;
uint8 RxData;
_INTERRUPT_VOID SPI_vRxISR (void)
{
if(SPIS==0xA0)
{
RxData = SPID;
ubSpiStatus = 1;
}
}
spi_Write(
