i use an wemos board
one SPI ist the for the TFT Port and a other for the SD Card.
Only Difference ist an other Chipselect Output.Pin- mosi/miso usw use the same Pins - technical no problem
The Driver for the TFT toggels the Chipselect - so no problem -
but toggels the SD Card Class the CS Pin ?
CS High > low > read/write > CS High - that is what i need
Or must i write an toggel the CS Pin def for read/write to SD
Multi Connect SPI
Re: Multi Connect SPI
Hi,
Sorry I don't quite follow what you're asking.
It sounds like you have two devices on the same SPI bus, with their own nCS pins, and that the TFT driver is doing the right thing with its nCS pin. Is the issue that the SD card driver doesn't use a CS pin? On ESP32, the machine.SDCard class takes a CS pin to the constructor.
