Re: Drivers for Waveshare 2.13inch E-Ink display

Hi,
I found a example code written for STM using HAL.
This contains a driver as well. Might be a good starting point.
However, same as Peter, I miss a programming documentation.

Best

Re: Drivers for Waveshare 2.13inch E-Ink display

Hi, afaik, there is no driver yet. I placed an order for a display a few days ago, hence, if I find enough time there might be something in the future but I can't promise anything. If money is no problem, it helps a lot to send one of the displays as a present to some of the more active developers ;...

Re: while true in boot

There is something else wrong. As you can see from your code example, you only define a few functions. They never get called. Thus, you should not expect that you reach the while true loop. Could be as simple as a small error, which threw out some exceptions and stops execution. Hence, you main.py w...

Re: New chip ESP8285

Hi LulaNord,

well that sounds interesting and has a value on its own but it does not tell us anything about Micropython on the ESP8285 ;)

Re: Newly flashed D1 mini disconnects after a few sec

I fried one of my mini boards by putting 5V to the 3.3V pin by accident. Well, it killed the LDO which now gets burning hot powered from USB and it applies 5V to the ESP chip, instead of 3.3V The point why I am writing this here. The ESP works fine. However, it gets hot and possibly will receive dam...

Re: Touch GUI for the official Pyboard display

It's just too bad that micropython hardware is so expensive compared to the Arduino/Pi ecosystems... Well, that is not true: 1. This is about comparing apple with pears... A 32bit uC at > 100 MHz is more expensive compared to a 8bit uC at 16 MHz... but they both serve a different purpose. 2. The ES...

Re: IPython Parallel, Hub-Workers, MicroPython and ESP8266

That looks indeed very interesting.
Thanks for sharing.
What is the aim of the ANN example? Any application behind it?

Re: Sonoff Touch with ESP8285 and Micropython

no not smaller.... bigger 86mm frame vs. 71mm drill distance for German junction boxes.... that means you can't get two of those switches in a row nor does the switch fit in a standard 2x, 3x, or 4x frame as we know it in Germany. Well basically, the touch is a single tiny sensor plate of a few cm r...

Re: Sonoff Touch with ESP8285 and Micropython

Yesterday, I noticed another annoying fact which is going to be a project killer for many of us. I tried to install the switch for testing and noticed that the frame of the switch is 86mm x 86mm. At least in Germany the space between two junction boxes in a row (or column) has to be 71mm. This is a ...

Re: Driver for WS2812 RGB LEDs (NeoPixels, ...)

Beside of deshipus comment, many sources on the net state that you should use some resistors and blocking capacitors in front of the first LED since they tend to be quite easily harmed by voltage spikes. Honestly, speaking I never did this and did not kill a single LED yet. Just wanted to mention. A...
