Modbus RTU Protocol Overview - rtautomationcom

Using the Hardware Serial Ports , Modbus controllers, serial interface displays and many other serial devices. The most common issue with serial ports on Teensy is use of code designed for Arduino Uno with Serial within the code. On Teensy This simple example shows how to use both the UART and USB Serial at the same time. Both are

/14/2014Uart and modbus Hi guys. I am trying to get the uart on the explorer 16 board to communicate via modbus. I am not sure if I need to detect the two stop bits at bits 10 and 11 of the data stream and create 3. 5 character delay for the start bit or does the uart do a lot of the work itself.
