Hey, thx for this good python module :) I've one question: is it possible to switch dynamically between MPSSE mode and UART ?

Thx in advance.

I'm not sure to fully understand the question.

You want to close the MPSSE port and re-open it as UART. However the port configuration is lost, and you may experience glitches on FTDI output pins.

Thx for your support. I have a non conventional application:

I have to be in input PU on RX and TX pins in default (I configure it via eeprom with ft_prog so it's OK)
Switch to UART mode to send some data over serial
Return in MPSSE input PU on RX and TX pins

Sorry, I do not get what "PU" means here.

I'm not sure how FTDI behaves with an alternative EEPROM configuration. FTDI doc is quite sparse on this matter.
