This installment of Elektor Books presents three ‘learning-by-doing’ sections and two ‘nice to know ’ paragraphs excerpted from the book Programming the Finite State Machine — with 8-Bit PICs in Assembly and C. Aimed at Microsoft Windows and Linux users, the book is based on a simple toolchain including an FTDI serial lead as the programmer, and open-source ‘gpasm’ as the assembler. Here we show the PIC assembly-language approach to an LED Flasher, Multiple FSMs in one program, and a 7-segment LED driver.
