Re: Debouncing inductive sensor input

not sure if it is a good way but what I usually do is in the first line of the call back function I disable the interrupt to stop it triggering lots of times then I have a small de-bounce delay then I execute the rest of the function then on last line of code before exiting the function I re-enable ...

Re: Intercommmunicating over SPI bus

Since all your boards have WiFi then it is probably easier to send data via WiFi than SPI. I am not aware of anyone using SPI in slave mode in Micro-Python. Although there is an I2C slave mode in many ports most of them don't work properly. The only port that I have seen work properly for I2C slave ...

5x5x5 Rubik's Cube solving robot

I have been super busy with work and other life commitments but today I found a little time to debug all the mechanics of my 5x5x5 Rubik's Cube solving robot.

It runs Micro-Python on my custom built board with a ESP32 Wrover module.

Re: Totally beginner. Does pyboard is good enough for 4 vehicle?

That's a really cool board, it is very new and not a lot of code has yet been written for it. There is the link I posted above and I have seen a couple of other blogs of people experimenting with it. The 8 bit parallel HW peripheral that reads the camera hasn't been wrapped up and exposed in Micro-p...

Re: Totally beginner. Does pyboard is good enough for 4 vehicle?

I make lots of robotics projects with Micro-Python and it is very fast development. You will certainly be able to create the project that you want easily. I have an openMV cam myself and love it. The down side is they did break out many of the IO pins. It is easy computer vision in Python but if you...

Re: RA8875 TFT driver displays

Have you though about the FTDI EVE sceens like GameDunio uses.

see https://www.youtube.com/watch?v=SfL8NtfFfio

Here's a very cheap 8=5" 800x480 screen with the FTDI chip on it https://www.hotmcu.com/5-graphical-lcd- ... p-286.html

Re: Charging 3,7v LiPo battery

20190123_065923.jpg Here is the 2000Mah that I use as I find it small enough to fit on my projects. Charging with 1 of those modules at 1amp is 1/2 C which is perfect slow charge recommend for battery life. The TP2406 is a very good CC/CV charger with a very nice charge curve for Lithium batteries....
