how to use the hardware SPI?

Post by cheche » Thu Sep 07, 2017 2:24 am

Hello everyone！
My name is Cheche, I'm from China, I'm an amateur electronic fan, I have a question to ask, I have a LCD with ILI9341 chip, but using softSPI is too slow,so， Can I use ESP32's hardware SPI?(machine,SPI is softSPI ? right?)
Thanks！
By the way, I'm not very good at English！ :D

I have experience with the hardware SPI support that the @loboris port Micropython_ESP32 provides and it works great and you don't have to be using psRAM to use that port. Also, it has a display module display module that supports the ILI9341.

Hi Cheche,

The hardware SPI is enabled by passing a hardware ID as the first parameter.

machine.SPI(1,miso = machine.Pin(12) ... )

If you use the "native" pin, the you can get much higher speeds.
