Hi - thank you for your work!
I have a small problem running the example from the documentations (configured for my path) below and writing onto the GPIO ports in general.
use I2C feature
i2c = I2cController()
configure the I2C feature, and predefines the direction of the GPIO pins
i2c.configure('ftdi:///1', direction=0x78) gpio = i2c.get_gpio()
read whole port
pins = gpio.read()
clearing out I2C bits (SCL, SDAo, SDAi)
pins &= 0x07
set AD4
pins |= 1 << 4
update GPIO output
gpio.write(pins)
OUTPUT: Traceback (most recent call last): File "c:/Users/Pond Posphiwat/Documents/random/ft-gpio-ex.py", line 19, in
gpio.write(pins)
File "C:\Users\Pond Posphiwat\Documents\embedded-systems\drive\lib\site-packages\pyftdi\i2c.py", line 318, in write
return self._controller.write_gpio(value)
File "C:\Users\Pond Posphiwat\Documents\embedded-systems\drive\lib\site-packages\pyftdi\i2c.py", line 913, in write_gpio
(self._gpio_dir, value))
pyftdi.i2c.I2cIOError: No such GPO pins: 0000/0010
I have debugged it at every step and can confirm that everything is configured correct and the gpio pins are seemingly already configured (using gpio.pins).
Also, the 'direction' param in configure does not seem to be writing the pin directions for me and I needed to call gpio.set_direction() to get the output ports configured.
Has anyone run into similar problems or know a fix to this GPIO write issue? Thanks!
