RS-232 (Recommended Standard 232) is a standard for serial binary data signals connecting between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment).
Usage
There are 3 ways to have RS-232 compatible serial ports on your Armadeus board:
- Use the internal UART controllers of the i.MX(L/27) (2 on i.MXL, 6 on i.MX27)
- Load OpenCore serial IPs into the FPGA of your board and use it
- Use a USB <-> Serial adapter (not possible with an APF9328DevLight).
As soon as you choosed the best solution for your application, all the serial ports are used the same way on Linux: go here to have more informations.
