Triggering And Decoding Serial Protocols On An Oscilloscope
element14 Presents | Bald Engineer: James Lewis' VCP Profile | Workbench Wednesdays
Everything with a microcontroller has serial busses in it. Busses like UART, I2C, and SPI are very popular choices. When you have a problem with a sensor that uses one or the bus itself, you can use an oscilloscope or logic analyzer to “decode” the traffic. These decoders convert the 1s and 0s into readable HEX or ASCII characters.
