The GPIO samples are transfer in both direction with the exchange() method, which therefore always returns as many input samples as output bytes. This is described in more detail in the FT232R bitbang app note. As these chips have tiny I/O buffers, it doesn't guarantee overrun-free operation so it may lose Articles Embedded C & MCU FTDI MPSSE Serial Engine Programming Tutorial: Basics and A GUI Example Many MCUs don’t have the 1. py example Classes class pyftdi.
