My latest book has now become available on Amazon. Still Far Inside The Arduino continues the theme of Far Inside The Arduino and the Nano Every Supplement by using programming techniques and drivers more advanced than what Arduino promotes. Topics include: Distinctions among the various general purpose Arduino boards: ATmega328P based like the Arduino Uno …
When considering communication between or among microcontrollers, I’ve discouraged use of the SPI interface because of its lack of a buffered interface in all but the ATmega4809 Ardruino AVR-based boards. However the handshaking protocol built into the I2C standard interface makes I2C communication a safe, reliable choice. (The I2C interface is called TWI in the …
All of the USART examples are done but for RS-485. I originally was going to skip this since it is so similar to “1-wire” operation, but then decided to buy some RS-485 drivers and give complete USART coverage with examples. This chapter should be finished by the end of next week after the parts arrive. …
