*
* Hardware definition file coming with TinybasicArduino.ino aka basic.c
*
* - ARDUINOLCD, ARDUINOTFT and LCDSHIELD active the LCD code,
* LCDSHIELD automatically defines the right settings for
* the classical shield modules
* - ARDUINOPS2 activates the PS2 code. Default pins are 2 and 3.
* If you use other pins the respective changes have to be made
* below.
* - _if_ and PS2 are both activated STANDALONE cause the Arduino
* to start with keyboard and lcd as standard devices.
* - ARDUINOEEPROM includes the EEPROM access code
* - ARDUINOEFS, ARDUINOSD, ESPSPIFFS, RP2040LITTLEFS activate filesystem code
* - activating Picoserial, Picoserial doesn't work on MEGA
*
* Architectures and the definitions from the Arduino IDE
*
* ARDUINO_ARCH_SAM: no tone command, dtostrf
* ARDUINO_ARCH_RP2040: dtostrf (for ARDUINO_NANO_RP2040_CONNECT)
* ARDUINO_ARCH_SAMD: dtostrf (for ARDUINO_SAMD_MKRWIFI1010, ARDUINO_SEEED_XIAO_M0)
* ARDUINO_ARCH_ESP8266: SPIFFS, dtostrf (ESP8266)
* ARDUINO_AVR_MEGA2560, ARDUARDUINO_SAM_DUE: second serial port is Serial1-3 - no software serial
* ARDUINO_SAM_DUE: hardware heuristics
* ARDUINO_ARCH_AVR: nothing
* ARDUINO_ARCH_LGT8F: EEPROM code for flash EEPROM - platform fully supported now, yet no call 0
* ARDUINO_ARCH_ESP32 and ARDUINO_TTGO_T7_V14_Mini32, no tone, no analogWrite, avr/xyz obsolete
*
* The code still contains hardware heuristics from my own projects,
* will be removed in the future
