Discussion - Hardware / FT4222: issue with GPIO 2 & 3 simultaneously with I2C in mode 0
« on: December 11, 2018, 02:35:20 PM »
Hi,
I want to use the GPIO2 and GPIO3 simultaneously with the I2C interface in CNFMODE0.
for the configuration of the ports I have used the following procedure:
- initialization of interface A as I2C master
- suspend out deactivated
- wakeup interrupt deactivated
- initialization of interface B for usage of the GPIO
I did not get the GPIO's to work. I2C works fine.
