Hi,

I need help with writing code. I need to read angle and speed from AD2S1210-EP via SPI. Where can I get the information to do this?

Thanks,

Shiromini,
You can see example SPI code by using HalCoGen. In the about dialog, there is an example option. It will pull up the directory structure of examples for the device selected.

We do not have specific code for interfacing with ADCs. There are multiple examples for SPI, with and without DMA usage.

Hi,

Thank you. The example does transmit and receive: spiSendAndGetData(spiREG2, &dataconfig1_t, 16, TX_Data_Slave, RX_Data_Slave)
How do I only receive data because in my case I need to read data from the RDC?

What is the difference between spiSendAndGetData and spiTransmitAndReceiveData?

Many thanks,
Shiromini

Hello,
All functions for SPI communication are defined in "spi.c ".
spiSendAndGetData initiate SPI Transmits and receive Data using Interrupt mode
spiTransmitAndReceiveData - Transmits and Receive Data using polling method=
