Re: using SPI1 and SPI2 Simultaneous for w5500 and ILI9341
ILI9341 is connected to SPI2 on the PCB board. With the official core, only the library "Adafruit_ILI9341_STM.h" was able to work with SPI2 and "Adafruit_ILI9341.h" can't work with SPI2. if you can use ILI9341 or W5500 with SPI2 ،Thank you very much to give an example.

Re: using SPI1 and SPI2 Simultaneous for w5500 and ILI9341
there is also a problem with official libraries and official kernel, and it is not possible to use both at the same time. Try it yourself if possible.

Re: using SPI1 and SPI2 Simultaneous for w5500 and ILI9341
I also tested with the official core. ILI9341 is connected to SPI2 on the PCB board. With the official core, only the library "Adafruit_ILI9341_STM.h" was able to launch it. And the w5500 is also connected to SPI1. Which only the <Ethernet.h> library could launch it with official core. When I ...

Re: using SPI1 and SPI2 Simultaneous for w5500 and ILI9341
Does it means we can not use spi1 and spi2 simultaneously for two different modules?

Re: using SPI1 and SPI2 Simultaneous for w5500 and ILI9341
I'm sure the libraries are OK because Each one of them works properly alone. I even tested it on the breadboard. Each one works Correctly on any spi1 and spi2, But in the program, you can not use both at the same time. As soon as you use another, the previous one fails. I also used the adafruit ...

Re: using SPI1 and SPI2 Simultaneous for w5500 and ILI9341
I used these other two libraries according to the attached files that have the ability to define a SPI number during initialization. But the same thing happens again. After installing the second part, the first part will fail. For example, if I start LCD(ILI9341) first, it works fine. But after ...
