Hello,
I am currently trying to use the EMW3080 Wi-Fi chip on the B-U585I-IOT02A over SPI. I am using the Keil µVision IDE and I am trying to use a bare-metal approach without a HAL. I am trying to send data over to ThingSpeak from the temperature and humidity sensor that is built on the board. I have been having significant issues communicating with the EMW3080 over SPI. If anyone is able to provide some guidance, that would be very helpful. I am not able to get the SPI clock to generate. I do not know what SPI mode the Wi-Fi chip is, and I do not know what protocol I need to use to communicate with the chip. I have attached my main.c file.
Thanks for any help.
