PSoC4 SPI LoRa PROBLEM

MKocaman

Hello to everyone,
I'm new to PSoC and trying to learn. I have the PSoC4 CY8CKIT-041 kit. I'm struggling to run the LoRa module by communicating with SPI. The LoRa module is a module that I know well and that I run on processors such as STM32, Renesas. But I'm having trouble with PSoC, I'm stuck especially on SPI. I have attached pictures of SPI TX and RX functions and added the project separately. You can check. Can you help me for sending and receiving commands in SPI? Can you create the correct command functions for me? Thank you from now.

  • Hi  

    Wow - PSoC 4 - that takes me back a wee bit!

    So a few things first that I'll check with you.

    In the SPI_Tx function you are resetting and setting LoRa_RESET - are you shure that's right? (I don't have the LoRa module to check with).

    Also, I see there is a pin called LoRa_NSS - are you sure you are handling that correctly? Shouldn't you be driving that low for SPI transactions?
