Arduino IDE, board and build notes

Even this is is called Arduino build, I recommend using 32 bit ARM architecture micro-controllers and ESP32/Arduino, STM32Duino or TeensyDuino.

  • ESP32 is The low cost IoT device of today. It features inbuilt WiFi, two cores and plentiful resources. In practice the chip is so complex, that it cannot be used as metal: The Espressif operating system including FreeRTOS is a must. Noticing low ADC top speed of approximately 100kHz limits use for some applications.
  • Teensy 3.6 has really good performance and format that it can be plugged directly into my own PCB. Unfortunately has two big minuses: lack of debugging support and incomplete LWIP library port.
  • STM32F429, etc, Nucleo, on the other hand shines where Teensy lack, but it also has a downside when it comes to development boards: Nucleo cannot legally be reused “as is” as part of commercial project: You have to draw your own PCB and put the STM chip on it, starting already from first customer tests alpha version. STM gives you two good coices for development tools, TrueStudio or Arduino based platformio.
  • Performance on more powerful versions of actual Arduino is being tested. Even it is possible to load iocom in very minimal serial communication configuration to UNO with 2kB of RAM and 32kB flash, this is recommended. The iocom alone eats up practically all RAM and flash, leaving very little for anything else.

Copy iocom, etc. libraries to use

An Arduino library is compressed package of source code, not collection of compiled object files. These must be organized in a specific way. Running scripts below will copy and organize source files for arduino-ide use (STM32Duino, TeensyDuino, ESP32/Arduino or actual Arduino).

cd /coderoot/eosal/build/arduino-library copy-iocom-and-extras-for-arduino.sh copy-iocom-and-extras-for-esp32.sh

The organized files will be in subdirectory arduino or esp32 within /coderoot/lib folder. Platform IO will use files directly from this location. Zipping individual library folders under /coderoot/lib/esp32 or arduino will result zip libraries usable in Arduino IDE.
