We have our little HiD device from RPi but this is only proof of concept. Now we will do some planning and start working on the more advanced and helpful classes.
Today we will make our RPi a slave device connected to PC via USB. And this RPi will be detected as the keyboard.
We need Raspberry Pi Zero or Zero W with the micro USB connector.
I have some plans for USB port and to prepare for some strange failures let’s look into serial TTY.
We almost ported all functionality from GfxLCD into cili. The last one is the draw_text.
The GfxLCD uses Python class as the font description and cili must keep the same functionality. So this time handling Python classes in C.
We have huge memory leaks in cili driver. App crashes in about day of working. A good thing is they manifest only during image draw so let’s get to the bottom of problems and fix them all.
I had to take a long break but I hope everything is back on track and I can resume GfxLCD in C project.
After such a long time, I have no idea what was the plan and what was the next step 😉 I think we will try and run Doton on our new driver to see what is wrong.
So this is a good time to name this project, I call it cili.
Today we will try and draw images from our C lib. This is the next step with the wrapper. Why? Because we will be sending Python Object to C code and use it there.
It is getting weirder 🙂

This time we will add an ILI9486 via SPI support to our C code. And while doing it we will refactor structure and clean up the code (or do more mess :P).
I was thinking that C wrapper should be part of GfxLCD package but maybe it is better to create it as a separate module? We will see but this time the code is available @GitHub.
