I have a question that I can't seem to find an answer for. I have been working with an FTDI 4232H device in bitbang mode for the last 9 months or so, among other things, on a Raspberry Pi data collection platform. Most of it has been in conjunction with controlling
an Exar SP339 transceiver, and a FET to control power to the serial device. Pretty easy stuff.
Now my employer wants to read the state of a momentary switch, but without having to stand on the device polling it every few milliseconds. I saw that the Rpi python GPIO library has a capability to get an event on the Rpi GPIO lines.
I know that these are different from the FTDI GPIO lines. But I was wondering if anyone had implemented similar event driven functionality using libftdi? Or alternatively, could point me in a direction to implement such functionality myself? I'd be happy to
contribute back to the project, if it can be done. From looking at the device docs, I'm not sure it can.
Thanks in advance,
