Hi, @Alex: Thank you very much for your support!
I've moved my code to https://github.com/Panther2804/stm32/blob/master/F401/riot-f401-w5100/main.c - the code is a modified version of RIOT/examples/gnrc_networking. However, it is still not working, i.e. when I try > make flash The minicom terminal tells me: > [w5100] error: no SPI connection Here are the points are not sure about: 1. I haven't fully understood how to copy drivers/w5100/include/w5100_params.h and use that. Instead I have modified the file in-place and added the following #define W5100_PARAM_SPI (SPI_DEV(0)) // ??? #define W5100_PARAM_SPI_CLK (SPI_CLK_5MHZ) #define W5100_PARAM_CS (GPIO_PIN(PORT_B, 6)) // PB_6 #define W5100_PARAM_EVT (GPIO_PIN(PORT_A, 10)) // PA_10 2. I'm not sure if it is my (i.e. main.c) job to initialize SPI and/or GPIO and/or W5100_PARAM_CS. I've written the init() method in main.c for this purpose. But maybe it is 'too late' then?!?
