ESP8285 is a smaller version of ESP8266 and comes in three different beakout modules – ESP-M1, ESP-M2 and ESP-M3. The attractive part of this is the size of only 12.3 x 15mm. This being a Wifi module with several IO options it is ideal for my old Model Train Control System. This picture is of…
I started this blog with a Train Control System that basically failed big time on the positioning system. The solution I attempted was possible, but to large and expensive for small model trains. I later upgraded the control system to ESP32 which definitely is the path forward, but it is time to make another attempt…
This illustrates the BasicPI Firmware Stack in progress. What I always do in embedded applications is to make a “standard” main.cpp as follows: void AppInit() { // wire hardware } int main() { AppInit(); // start OS } A team I worked in years ago agreed on this standard so we should…
This was my first project that got me started on electronics again. The initial design did not work at all. It used an STM32 on one side and ESP-03 on the other which created too much interference + I had selected the wrong type H-Drive. The MCU and PSU design did however work well and…
