Re: ST7789 IPS 240x240 SPI display

If I initialize the SPI object like this :

Code: Select all

spi = machine.SPI(1, baudrate=60000000, polarity=1, phase=1, sck=Pin(14), mosi=Pin(13), miso=Pin(12))
It works at planned. Setting phase=1 seems to do the trick. But it's quite strange that with software spi and phase=0 it works also.

Re: ST7789 IPS 240x240 SPI display

This is quite weird to me. Hardware SPI doesn't work, but software does (on the same Pins). Bus 1 or bus 2. Said with code (miso isn't wired): spi = machine.SPI(baudrate=40000000, polarity=1, phase=0, sck=Pin(14), mosi=Pin(13), miso=Pin(12)) # works spi = machine.SPI(1, baudrate=40000000, polarity=1...

Re: ST7789 IPS 240x240 SPI display

I try to use your lib to drive a ST7789 with a esp32, but it doesn't work. I have used the exact same code (except I changed the .on() and .off() for .value(1) and .value(0)). No error but the screen stay black (with the backlight on). Have you ever tried it with an esp32 ? Edit: I tried with a fres...

Re: Current state of BLE?

Ok thanks, I didn't knew Pycom made a custom version of MicroPython.

I will join the slack to see if I could help maybe. Since Pycom successfully added BLE support, it should be doable to replicate it.

Re: Current state of BLE?

Hi,

I don't understand something. Maybe I'm wrong but I thought Wipy uses MicroPython, and with Wipy you have bluetooth support (in Python).
So how is this possible ?
