Connecting Arduino To ARC

I have an idea for you, but it’ll take a few days to make

DJ Sures, Thank you so much for your response. If you do think of a way that would really be great. You have no idea how much I've already struggled. I knew I was already taking on a big challenge. Thank you!

I have some ideas. Running a few excitements but the plan is to allow a robot skill to extend the servo ports into the Vx ports for arduino firmware. Stay tuned and thanks for the kind words

Im excited, thank you again!

I presume you will use your Arduino Mega to control a mix of servos and digital ports.

One easy option: change the firmware code to map:   EZB 0-23 servos to control arduino mega servo ports 0-23. EZB 0-23 digital ports to control arduino mega digital ports 24-47

so you can control 24 servos and 24 digital ports, is this ok ?

Oh that’s a good idea - it would be easiest change right away. Smart Ptp

DJ taking in consideration Arduino Mega hardware limitations:

I would map the following: Analog: A0-A7

Servos: mega ports D22-D43 = 22 Servos = EZB 0-21  mega ports D68-D69 = 2 Servos = EZB 22-23 Total = 24 servos

PWM Ports: mega ports D02-D10 = 9 ports  = EZB 0-8 mega ports D13         = 1 ports  = EZB 9 mega ports D44-D46 = 3 ports  = EZB 10-12 Total = 13 pwm ports

Digital Ports: EZB 0-12 = same as PWM ports in mega (above) EZB 13-14 = D11-D12 = 2 ports EZB 15-20 = D62-D67 = 6 ports  Total = 21 ports ( 8 exclusive for Digital IO and 13 shared with PWM ports)

pin 0 and 1 are serial port 0 / usb port (avoid these ports)

and you have the following: Serial1 on pins 19 (RX) and 18 (TX), Serial2 on pins 17 (RX) and 16 (TX), Serial3 on pins 15 (RX) and 14 (TX).

I2C: D20 - sda D21 - scl

With the above setup: 24 servos 13 pwm ports  / digital ports 8 digital ports 8 analog ports serial ports available/free i2c available/free

Super smart. I like it! I’ll make changes and publish. This will be much easier. Thanks again for the idea ptp
