Re: SPI hardware

yes it is initialise and i checked with a analyser logic, it's strange cs = Pin(15, Pin.OUT) some parameters are not accsessible (dma channel) With Arduino IDE, my peripheral answer to the transfert I don't see any example in micropython except fork https://github.com/loboris/MicroPython_ESP32_psRAM...

SPI hardware

hello, i use the spi in mode hardware , so i must configure the pin cs on the pin 15 as a chip select , but unfortunately my transfer don't work hspi.init(baudrate=400000,sck=Pin(14), mosi=Pin(13), miso=Pin(12),firstbit=SPI.MSB ) cs.off() hspi.write_readinto(b'\xE0\x00\x00\x00\x00\x00\x00\x00',buf) ...
