Hi,
I've found a bug which has been introduced into libftdi 0.17. The bug
did not exist in 0.16.
I'm using a FT232R as a serial port with the CBUS in bit bang mode.
The problem is after configuring the CBUS with ftdi_set_bitmode, I can
no longer set the baudrate correctly.
I believe the bug is on the second last line of the ftdi_set_bitmode
function. In 0.17 it is:
ftdi->bitbang_enabled = (mode == BITMODE_RESET) ? 0 : 1;
In 0.16 it is:
ftdi->bitbang_enabled = (mode == BITMODE_BITBANG || mode ==
BITMODE_SYNCBB)?1:0;
The ftdi->bitbang_enabled flag appears to cause the baudrate set to be
multiplied by 4. Therefore, in 0.16 when the mode is BITMODE_CBUS the
flag is not set and setting the baudrate functions correctly. In 0.17
the flag gets set and the baudrate can no longer be changed without
dividing it by 4 first.
I'm not sure about the other bit bang modes, but perhaps this change
should be revisited.
Thanks,
Logan
