Modified version of S220718-R240620

  • added an EEPROM editor
  • added I2C scan devices
  • modified clock to calculate speed of CPU
  • Moved functions above void setup{} and void loop{}
  • Optimized SRAM

Everyone is free to use it. It's tested by me with Arduino 1.8.14 with

  • PetitFS 0.03a library
  • avr-gcc version 10.0.2
  • avr-ar version 2.35 (GNU Binutils 2.35)
  • avr-libc version 2.0
  • MightyCore 2.0.5 ATmega32. https://github.com/MCUdude/MightyCore#how-to-install With a little mod it should work with an ATmega1284. (Change OC2 to OC2A) Also a lot of mods should work on the v20-MBC. (not tested still waiting for it.

20201017: - Updated the i2c (still need to optimize using int in place of byte) - Can recognize A110417 - Updated bootmenu showing what to boot - Clean out old remarked code - removed library LiquidCrystal_PCF8574 - Updated the i2c to auto configure LCD - Added Lcd.... routines to sketch (No library needed) - RTC not calculating correct DayOfWeek - RTC temperature still not correct
