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 …
Arduino provides a USART driver for treating the data as a stream, basically a never ending sequence of bytes. This follows along a tradition of sorts, basically popularized by UNIX in the 1970’s. However traditional (at the time) computers did I/O by records, blocks or packets, of data. And this is the basic operating method …
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. …
