The Joy of Connecting Elixir to the Physical World
summary
Shows concrete claims and working examples: Elixir’s binary pattern matching and functional transforms simplify messy device protocols, and OTP helps recover from flaky hardware. Demonstrations use nerves_uart over a USB-to-serial FTDI cable, parse GPS NMEA lines and line-framed UART traffic, and handle an odd 17 bits SPI/ADC exchange without glue code. Ends with creating standalone firmware with Nerves, cross-compilation details, and when to develop on laptop versus Raspberry Pi.
