Microchip Wi-Fi MRF24WN0MA

I am using the following devices from Microchip on an embedded system:

  • USB Starter Kit III (PIC32MX470F512L) + Starter Kit I/O expansion board
  • MRF24WN0MA.

So I use the SPI1 channel for communication with a 6-axis sensor (all works fine). Then I want to transmit these data through the SPI2 to my WiFi module (MRF24WN0MA), I chose it because I need a wireless module with a minimum data rate of 1Mbits/s and a reliable communication.

I am using MPLAB Harmony v2_02_00b to configure the WiFi module. I have tested several example projects provided by Microchip as "wifi_easy_configuration", "wifi_ap_demo" and they don't work for me. I followed this tutorial to migrate the project toward my PIC32

Solution

  • Due to the lack of documentation in the datasheet of this module and several other issues, i switched to the MRF24J40MA which has lower data rate but a complete datasheet (registers included!).
