![]() ![]() Conversion to decimal can be done by googling “0xHEX_VALUE to decimal”. These can be both be found under the device properties within the system profiler. Grab the VID and PID of your USB UART adapter, and convert them to decimal.Install the FTDI VCP Drivers for Mac OS.I only located the Mac OS application note after figuring out the procedure myself, so I’ll break it down here for you. This is a task FTDI has outlined quite well for windows in an application note, and it is also buried in a application note for Mac OS X. As such, I was left with the task of aliasing some other standard baud rate to 3.2MBaud in the virtual com port drivers. These extended baud rates are readily available with FTDI’s D2XX drivers, but I wanted to retain the ability to use a standard serial programming API to communicate with the hardware. Since this is a nonstandard serial rate, I set out to find a way to configure a relatively cheap USB UART bridge that supported communications at this speed.įTDI makes a chip called the FT4232 that has four separate UART interfaces and supports baud rates from 3MBaud to 12MBaud using some extended clock settings. For a recent project, I needed to interface my computer to an embedded device over a RS-422 connection at 3.2Mbaud.
