Hi.

I want someone to check my wiring out and tell that if there is something wrong or is it good to go. Also, A/D and PWM are build-in in ECIO 40P, right? Meaning that I don't have to attach any more components to my circuit.
LCD has brightness POT, I'm not sure if the buttons are wired correctly but otherwise it should be fine.

Pins in CONN-H12
1. In +12V
2. Out +12V (wired straight to pin 1)
3. Out +5V (from Ecio's VDD out)
4. GND (This is -Voltage also(?))
5. A/D output1 (for this and A/D output 2 I don't need anything else, just to program it to work as A/D output?)
6. A/D output2
7. PWM output (same question as for A/D)
8. Digital I/O (these are just easy use to connect more devices)
9. Digital I/O
10. Digital I/O
11. Digital I/O
12. GND 2 (Because CONN-H12 has 1 extra pin, I figured to use it as GND 2)

Hello,

Looks good to me. You mention the A/D as Analogue out but these are in fact analogue in i.e. ADC not DAC.

There is no dedicated DAC onboard the ECIO device but you can use PWM with a capacitor as a basic DAC. Otherwise you may need some form of SPI or I2C DAC.
