[libopenstm32-devel] gpio.c problems

[Thomas O. <to...@vi...>]

Hello,

I had 2 problems with the function gpio_set_mode().
1. it generally sets the submited config to the mentioned gpio-pins but
kills configs for other pins on the same gpio port. So if i want to set
PB6 and PB7 to push-pull and I2C2 SDA and SCL (PB10 and PB11) to open
drain its simply impossible, because the second config try kills the
first.
2. the floating-bit thing isnt working correctly. if i enable a config
for PB6 for instance the same config will also apply to all following
pins of that port (aka PB7-PB15). Thats because the shifting isnt only
done if a pin isnt to configure, if you are hitting a matching bit the
shiftig is missing. I think shifting isnt nessessary for a separate
variable. We have the counting index from the for statement.

so I've rewritten the function a little bit to address these problems.
Patch is attached.

Best regards,
Thomas Otto
