I've posted this unofficial guide to the Pyboard D. Some of the content is based on my testing, the rest on information from Damien (reproduced with his permission).

Any additions/corrections/PR's/comments from those with boards are welcome.
Now I just need to be able to buy one! :(

Where is the official presentation and documentation for Pyboard D?
The board is not available yet, it should be on the next few days (or weeks).

Re: Help writing SPI library (FT813 lcd driver)

I got a logic analyzer to find out what exactly my code was doing and could compare with a working example that worked on arduino. Finally got my code to read the ID! So now is on to implement the other functions and get the display working no micropython! :D import time from machine import Pin impo...

Re: Help writing SPI library (FT813 lcd driver)

OutoftheBOTS_ I I'm using a pyboard. I've used the SPI before, even converted some Adafruit Circuit python libraries to Micropython. hopefully I'll be able to figure it out and write a library so whenever you wanna play with it you would have a head start. I'll try check the data with a logic analyz...

Re: Help writing SPI library (FT813 lcd driver)

@OutoftheBOTS_ I saw multiple libraries and studied all of them, but that does not help me . They are following the datasheet my problem is how to implement that on micropython. @loboris I saw your port, my initial goal was to implement the library in python, instead of C with bindings, so it would ...

RA8875 TFT driver displays

Hello Everyone, I started porting to micropython and adding some functionality to a library that melissa just started for circuitpython. Unfortunately I justtttt got started with micropython, I wish I could get the library as a subclass of framebuf (would the performance of the driver improve?), but...
