I´ve just started to work with the BBB. I´m trying to acquire four analog signals, process them with the BBB.
Last the results should be shown on the screen. (any type of Graph or anything like that)
I already accepted that i can´t use the four analog inputs that aren´t used by the LCD cape.
So I think I´m going to use a simple ADC and set each signal to one of the unused GPIO.
Is there any type of cape, which can be placet between BBB and LCD cape, where i can easily acces the unused GPIOs?
Or would you recommend to solder it directly to the BBB? Or is building an own circuit board a better idea?
Thanks for your help!
Used HW: BBB + CircuitCo BeagleBone LCD4 cape and LCD display
