I am working through this chapter and found that nothign happens when I use the shell command
sudo gpio -g write 17 1
but it does work when I use the python program and use
GPIO.output(17,GPIO.HIGH)
What could cause the shell script to not work while the python program does work?
I read your book of Raspberry pi Sensors.Thanks.
I was wondering about the calculation at the end of chapter 5.4 of the book.
It says that:
00000010<<00001000 = (1000000)b = (127)d
Is it should be:
00000010<<00001000 = (10 0000 0000)b = (512)d
