Error with CRC_GetBlockCRC function

nadiajarray — Tue, 09 Aug 2016 14:27:21 GMT

I'm trying to use the CRC component to check an SPI communication

but by using the function CRC1_GetBlockCRC this way

CRC1_GetBlockCRC(CRC1_TDeviceData, &RVG_SPIReadBuffer, RVG_SPIReadBufferSize*sizeof(uint8_t), &ResultRead);

I'm getting the error "expected expression before'CRC1_TDeviceData'

Can someone provide an explanation for that ?

Thx

Hello Nadia

How did you define the type for CRC1_TDeviceData?

Below is the typical way for initializing the device data structure and call API function:

LDD_TDeviceData *DeviceData=NULL;

………………………

DeviceData = CRC1_Init(NULL);

………………………

CRC1_GetBlockCRC(DeviceData, (LDD_TData*) InputStream, BLOCK_SIZE*sizeof(uint32_t), &Result);

Hope this helps! If not, could you please attach a simple example project to help me reproduce the error? Thanks!

Best Regards
