I want to use an FlexIO in UART Mode, to work as Modbus Slave or Modbus Master, using interrupts.
Can somebody guide me to configure all the features to make the FlexIO-UART respond to modbus rtu?
I am using an FRDM KL43Z.
Please download KSDK for frdm-kl43 from https://mcuxpresso.nxp.com. There are many flexio-uart examples in FRDM-KL43Z\boards\frdmkl43z\driver_examples\flexio\uart.
FlexIO hasn't CRC function. You have to do it by software.
