Discussion - Software / Question about FT4222 GPIO pin
« on: June 28, 2018, 02:37:06 AM »
Hi,
Consider these 3 successive function calls:
FT4222_GPIO_Write(ftHandle, GPIO_PORT0, 0);
FT4222_GPIO_Write(ftHandle, GPIO_PORT0, 1);
FT4222_GPIO_Write(ftHandle, GPIO_PORT0, 0);
This is how I output a pulse in GPIO pin 0. The logic analyzer shows that when I do this, the GPIO port 0 signal remains high for 200 us which is too long for my app. How can I control for how long the signal will be 1?
Thanks.
