They’re here! Time to give one a spin with Espruino.
I’ve been working on a whole bunch of projects involving microcontrollers in the last couple of years, I’ll quickly go through what I’ve used and where I’m heading with them.
Of course I’m starting here! Basically, I kicked off with Arduino pro mini clones as a super cheap way of making my own devices, and of course used the Arduino IDE. Before the advent of the ESP8266 I was fiddling with NRF24L01 radios and an assortment of Bluetooth modules. The NRF24L01 was very useful for being low-power and there being a lot of projects for it and I started with Maniacbug’s Rf24Network library, progressed to TMRh20’s version and then finally MySensors. I really like how useful MySensors is for standardizing messages, so I’m actually using the protocol for some Wi-Fi sensors. I’ve moved over to using PlatformIO IDE and I’m currently building Atmega328 boards in the Adafruit Feather form factor with NRF24L01’s on them.
About a year ago I gave Espruino a go on my STM32F401 Nucleo board to see how it worked for me. I was amazed at how great it was to use, especially for prototyping. I bought an Espruino Pico to use for a bit, then moved to making my own boards with a form factor suiting me. STM32 + Espruino is my go-to for microcontroller projects.
This hit the scene and made waves around the world, and it has been useful for me. I’ve used it as both a radio with STM32 boards and as a microcontroller running Espruino.
This turned out to be the main BLE chip running around for a while and I’ve fiddled with using it with Espruino. Probably will end up being replaced by the ESP32 for me though.
I’ve had a play with a few other chips, Attiny84, Attiny85, some assorted dev boards, but those were the main chips I’ve been using.
