Book Description

Obtain the best performance from the ATmega4809 microcontroller in the Arduino Nano Every board by accessing features not utilized in the Arduino software library. This book is intended for those familiar with the ATmega328P in the Arduino Nano or Arduino Uno boards who want to take full advantage of the features in the Nano Every. Owners of the Far Inside The Arduino book will obtain the same in-depth treatment of the Nano Every. There are over 40 example programs, provided as a download from the authors website, illustrating the new or different features of this microcontroller.Topics include (with examples): -The Event System-Configurable Custom Logic-Changes to the memory map and EEPROM accessing-Changes to the ADC, Comparator, Timer/Counters, Watchdog Timer, SPI, USART, and TWI.-The new Real Time and Periodic Interrupt Timers -Arduino Library modifications for higher PWM frequencies, 1μs clock resolution, 8 times faster ADC, and 20MHz system clockExample programs demonstrate all 8 Timer/Counter B operating modes, and three Timer/Counter A operating modes, including using the Event input. There are also example programs for operating the TWI interface as both master and slave simultaneously, using the SPI as master and slave, with buffering for the slave, and for the USART asynchronous, synchronous, 1-wire, RS-485, and as a SPI master.
