Decoding UART, I2C and a non-standard signal // With Saleae logic analyzer and temperature sensors

#saleae #i2c #uart
Logic analyzers can be used to peak into the actual signals used to communicate data. We will also use it to decode the signals into various protocols such as asynchronous serial, I2C, and even dig into some datasheets to decode a non-standard protocol all using common sensors connected to an Arduino board.
