1. can I use pins : 2(bootl), 1 , 0(i2c2,tx3,rx3) to connect a 'led' or a 'push button' ?
2. can I use pins : 15,16 for i2c ? If i dont use those pins for i2c, can it be used for gpio purpose?
3. pins 23,24 are labelled as usb. If I use pins 23,24 as gpio, will it cause any problems in uploading programs?
I dont want to test it out myself as I have only one board. So I posted this question.
Maple Mini, Maple Rev3, Maple Rev 5 and Maple Ret 6, iTead Maple etc
