@pythoncoder thanks for sharing your code, I know you have posted links to it before but this time I sat down and took the time to look closely at your code. It was simple enough to understand how writer.py works. It was the first time that I have seen memoryview() and will be incorporating it into ...

Thanks Mattyt for the offer but I do have a board that I designed and built for a 2 dc motor turtle style robot. I used 2 x L9110 h-bridges because they use less pins and have the lowest forward voltage off all the h-bridges that I played with. I also put 2 x LS7366R encoder counter chips on it keep...

Thanks guys

I have a few other ideas for cool robots.

The ESP32 Servo Board should go into production shortly for anyone that wants to buy 1.

At some stage when I get the physical robots sorted out I will make all design pubic and a tutorial on how to build them and put up my code open source.

If you also don't have the 10uf and 1 uf on the 3.3v line close as possible to the wroom module then you can also have brown out stability problems as well.

Just though I would share another robot that I have been developing. It is a worm robot and it produces locomotion by wiggling like a worm. The Worm robot's locomotion speed and steering can be controlled with any web browser. I use my ESP32 Servo board that I designed with Lobo MicroPython to drive...

There is also a known problem of the EN pin needs a 100nf cap to ensure stability of the EN pin. See the Peripheral Schematics from the Wroom datasheet

Have you tries this driver https://github.com/mcauser/micropython-waveshare-epaper

It was written for pyboard so will need to change the way it handles pins but should be easy to get it to do what you want

I use ampy to write files to ESP32 Loboris port on windows PC but use putty for repl terminal

I am in the stage of testing my finial prototype ESP32 dev board before putting it inot a small production run. It will have a ESP32 Wrover (psRAM), 1.8" TFT screen, User buttons, PCA9685 16 channel PWM servo controller chip, 10amp buck converter to run the servos. see my demo video at https://www.y...

I got this in an email to day about the next generation OpenMV cam getting ready for release. I have the current OpenMV M7 cam and it's great. It runs micropython to do computer vision on an MCU Check out the OpenMV new cam at https://www.youtube.com/watch?v=1Bfa0TnSIFc&feature=youtu.be&utm_source=O...
