I want to implement RS485 to UART on my board. My board is based on the FRDM K64 as a reference board, so currently I'm trying to figure it out on the FRDM K64.
Host computer USB -> this cable -> RS485 to uart board -> Bluetooth connector on FRDM K64 -> UART4 on MK64 chip.
Well, unfortunately, it does not work. The computer detects the USB to RS485 cable as expected, and gives it a comm port (I see it in the device manager). I connect the USB cable to the J26 connector on board the FRDM K64 to burn the flash (as always) and try to read on UART4 what I write in UART0.
Any ideas why and how to make it work?
My whole project relies on this communication.
