I write about using MicroPython and Forth with microcontrollers as well as practical electronics and inexpensive test equipment.
Comparing the Labrador
Where I compare the Labrador with the $300 Digilent Analog Discovery 2 and determine if using a “rail-to-rail” operational amplifier matters.
RP2040 MicroPython Coding Setup
Where I explain my process for developing code on the RP2040 board.
RP2040 Blink Continued
Where I use the Labrador to test a different way of implementing Blink on the RP2040 using timer().
Introducing Adafruit Feather RP2040
Where I begin to work with the Adafruit Feather RP2040 (Feather) and MicroPython (uP) and use the Labrador to test the board.
ESP32 MicroPython Coding Setup
A short entry to explain how to code using MicroPython on the ESP32.
Testing MicroPython with the Labrador: PWM
Where I continue to use the Labrador to test the PWM functionality of the ESP32.
Testing MicroPython with the Labrador: Blink
Where I use the Labrador to test specific functions of the ESP32 running MicroPython.
Where I investigate using MicroPython on the HUZZAH32.
Where I find a much, more evolved version of ESPForth.
Where I write an Arduino program to test pins on a specific board in order to confirm a Forth HAL for the same board.
