Working on 32 function button box. It calls for a pro micro. I could not get sketch to load.
I ordered and received Arduino micro.
How to do I wire a project that used a pro micro to a micro?
The labels for the pins are different.
Pro micro - pins
top row of pins - raw, gnd, rst, vcc, a3, a2, a1, a0, 15, 14, 16,10
bottom row of pins - tx,rx,gnd, gnd, 2,3,4,5,6,7,8,9
Micro - pins
top row of pins - 12~ , 11~, 10~,9~,8,7,6~,5~.4~,3,2,gnd,rs,rx,tx,ss,mo
bottom row of pins - ~13,3v,REF,A0,A1,A2,A3,A4,A5, unmarked, 5V,RS, GND, VI, MI,SCR
10 - momentary switches
2 - 2 way toggle switches
4 - 3 way toggle switches
4 - rotary encoders
Some of the pin descriptions match. Some do not.
I searched the data sheet for the pro micro
Digital i/o pins - 12
Analogue input pins - 4
I searched the data sheet for the Arduino micro
Digital i/0 pins - 20
analogue inputs - 12
It should be able to work.
So questions are:
~ does that mean both digital and analogue inputs can be used on this pin? Is 4 on a pro micro the same as ~4 on micro?
There are no equivalent pins descriptions for
RAW, RST, VCC, 15,14,16
Thanks in advance for any help?
