Other Parts Discussed in Thread: MMWAVE-SDK
I am using IWR6843AOPEVM + mmwaveboost
I want to receive TLV or 1DFFT data through spi communication. No errors were displayed during initialization but cli didn't work.
Communication is added to the void MmwDemo_uartTxTask(UArg arg0, UArg arg1) part.
I tried adding it to another project vital sign, but an error occurs during initialization
Do any of the mmwave_industrial_toolbox/lab demos have spi capabilities? Or is it possible to attach a mmwave_industrial_toolbox/lab project by adding a function?
I'd appreciate it if you let me know if I'm wrong in the code or if there's anything I need to add.
