UM232H

../../_images/um232h.jpg

The UM232H is a USB-to-serial/FIFO development module in the FTDI product range which utilizes the FT232H USB Hi-Speed (480Mb/s) single-port bridge chip to handle the USB signaling and protocols. Official reference can be found here

Configuration

You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):

[env:myenv]
platform = ...
board = ...
debug_tool = um232h

If you would like to use this tool for firmware uploading, please change upload protocol:

[env:myenv]
platform = ...
board = ...
debug_tool = um232h
upload_protocol = um232h

More options:

Drivers

Windows
Mac

macOS contains default FTDIUSBSerialDriver driver which conflicts with debug tools which are based on this chip. FTDI Chip company recommends removing this default driver from a system. Everything should work after system rebooting. See detailed instruction in official application note (Page 16, Section 4: Uninstalling FTDI Drivers on OS X) AN134: FTDI Drivers Installation guide for MAC OS X

Linux

Please install “udev” rules 99-platformio-udev.rules. If you already installed them before, please check that your rules are up-to-date or repeat steps.
