#125690 - µC not latching data from the SPI Bus |
Hello everyone,
I am currently working on a project which involves communication between an Infineon XC888 with a TI ADS1256 (ADC) using an SPI Interface. I can successfully send commands to the ADC, but reading the data send back to me is not working at all. For example: SSC_vSendData(0x14); // send the Read Registry command
SSC_vSendData(0x00); // send # of bytes to be read (1+0x00) SSC_vSendData(0x00); // send Dummy Byte SSC_Data = SSC_RBL; // storing of the received data When I look at the scope, the returned signal on the DOUT line looks perfectly fine, but when I read the Receive Buffer (SSC_RBL), it's always empty (0x00). I also can't image having any timing problems, after all, the Microcontroller should always leave the data in the SSC_RBL register until new data is being send. Thanks in advance. PS: SSC_vSendData() puts the byte in the SSC_TBL register and waits until the Busy flag is cleared. |
