I got BBB and start enjoying.
I wonder How to work pullup pinmode at input in software.
I want to pull up P8_31(GIPO_10) as Input 、but it effect noting.
2.b.pinMode(“P8_31”, b.INPUT, 7, ‘pullup’);
Both are in same result and P8_31 never pulluped.
Of course when I connected a 10Kohm resister between P8_31 and VDD3V3 , It pulluped and work fine.
I want to omit this resister.
Many chips (PIC & AVR & etc…) has software pullup mode and no need to connect extra resister. But In BBB It doesn’t work?? Always need extra resister?
My BBB’s info:
Your board is connected!
BeagleBone Black rev 00A6 S/N 4613BBBK1318 running BoneScript 0.2.2 at 192.168.7.2
I want some help, Please.
I know in BBB it is limited 4mA or 6mA for GPIO current.
My question is total current limitation in BBB. Is there any limitation for total current?
