I have a problem with Bit Bang Mode.
I have collected a unpretentious breadboard model on FT245BM. I want to program it in Bit Bang Mode that all bіts in this mode were outputs.
It is impossible...
Are normally programmed only first three bit!!! It is possible to write to them normally 0 and 1.
After connection of a device to USB at reading I receive all 0 on outputs but as soon as I write 0, after reading already I receive 00110000:-((
Whether someone has an example
of the program which uses this mode for all pins which
are set as output pins.
