I'm trying to figure out how many GPIO pins I can use on the EULER bus, from the schematic I see some which look like they may be usable as GPIO so long as I don't need their 'primary' functions....
For example PB3,PB5,PB6 are labeled as I2S_MCLK,I2S_BCLK and I2S_DOUT, can I use the as gpio??
If so, I see the following pins available for GPIO (please correct me if any of these won't work as GPIO)
PB3,PB5,PB6,PD2,PD3,PD1,PB2,PB8 on one side (assuming I don't use the uart for uart stuff)
And PH8,PB4,PB7,PD4,PD5,PD0,PD6,PD7 AND PB9 on the 'right side of the schematic'
Total: 8 + 9 = 17 GPIO available on EULER??
My project needs as many GPIO as possible, communications etc will all be by ethernet once data is collected into ram)
Thanks!
