ESP 32 LORA with another SPI

#1

Hi, is it possible to connect two SPI (one RFID with SPI and LORA)?

I tried to use HSPI and VSPI, however without success! I read in one forum that when I use GPIOs for SPI, i.e. RFID GPIOs, it limits the SPI communication to 40MHz. This means that LORA will not works.

Thank you in advance for all support.

Please refer to this example:

ESP32 chip have IO_MUX function, so any free GPIOs can be configuration to SPI bus.
