I could send you a modified rshell that would help me to understand what's going on.

I would be great!

Hi! I just bought a Pycom Wipy 3.0 board, and I'm trying to use it with rshell. Everything seems to works, except files transert. For example: > cat /flash/main.py # main.py -- put your code here!Traceback (most recent call last): File "/usr/local/bin/rshell", line 10, in <module> sys.exit(main()) F...

Hi! I'm planning to use an ESP32 and a gen4-uLCD screen, from 4D Systems, and program it in ViSi-Genie mode. 4D Systems provides an Arduino library, and I'm wondering if someone has already implemented a micropython module to communicate with the screen in this mode? I only found this: https://githu...

Hi Matt, Integer. The PWM capabilities of the ESP8266 are quite weak; a maximum base frequency of 1KHz and 10bits of duty (ie 1024 levels). That said, I don't understand your math; how did you arrive at 75 positions? For servos, you have to set the period to 50Hz. So, max value, 1023, is 20ms. As th...

Hi! I will soon drive my 24DoF hexapod using my Python framework¹ on a RPi, with a custom shield using 2 PCA9685; all movements (synchronized) are done in Python. But I would like to test another solution : having a node per leg, to drive the 4 servos, and also read some inputs to detect the ground....

Thanks!

Hi! I'm finally making tests with my Wipy 1.0 (kickstarter) boards... My first project is to replace an Arduino I used to make a fancy Stargate clock, using RGB bus leds. The nice thing is I will be able to automatically sync with a ntp serveur to set the current date/time. I used a recipe for ntp, ...

Great work! Thanks for sharing.

Yes, I know these projects; I'm working on the Arduino library, to clean it up. Then I will start to port it to micropython.

The idea is to dedicate a pyboard as a LCD interface, to build some sort of VT100 terminal.
