Adafruit Motor Sheild V1.0 as a Breakout Board

Post by Shubhs »

Hello there,
I am having adafruit motor shield V1.0. My question is, how can I configure PINS other than PIN allotted for motor shield and make it use as a breakout board using the same AFMotor Library? Reason is, I want more number of PWM Pins other than Pin 44,45 & 46 in Arduino Mega.

Actually I am NEW to this Electronic World. Initially I thought that for LCD PWM Pins is required, but it was not so.
I am having adafriut TFT LCD (2.8") and I want to use it as a shield using the adafruit_TFTLCD library. And I want to use 1 STEPPER MOTOR with adafruit motor shield V1 using AF_Motor library. So the PIN allotment in the Libraries of adafruit_TFTLCD and AF_Motor library i think are conflicting hence I can't see updates on LCD. But when I am making AF_Motor library as a comment line with also some other code lines related to it as a comment line, Display starts working. So how can I use it as a breakout board so that I can run LCD and Stepper simultaneously.

There are too many pin conflicts. I don't believe those two boards are compatible.
You should upgrade to the V2 motor shield. That requires only 2 pins.

Still is their any possibilities??? I think if I change the PIN numbers in .cpp & .h file, my problem can be solved & even I have tried it also. But didn't get the desired output. The LCD Screen was not working when I am using it as a shield. But any how I have made LCD to work as a Breakout Board but I couldn't able to do the same with Motor Sheild V1. So I believe it is possible to do so. Right now, I am using LCD shield as a Breakout Board and motor shield as a shield. But I want to use it reversely i.e. motor shield as a breakout board and LCD shield as a shield. So please kindly help me.

The pin requirements for the motor shield depend on the motors you are using. https://learn.adafruit.com/adafruit-mot ... faq#faq-12
If you are using all of the motor channels, you will not have enough pins left for the LCD.

I am using 1-Stepper motor(Nema 17) as I have mentioned earlier. So I don't have all the channel requirements. I only want to use either "M1 & M2" or "M3 & M4" ports. thats it! So how can I get that? as a BreakOut Board. :(

The link above lists the pin requirements for steppers:
The following pins are in use only if the DC/Stepper noted is in use:
Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)
Digital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)
Digital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)
Digital pin 6: DC Motor #4 / Stepper #2 (activation/speed control)

The following pins are in use if any DC/steppers are used
Digital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595 serial-to-parallel latch

I have change the pin configuration in the .cpp & .h file and then connected the motor shield as a Break-Out Board but still I think adafruit_TFT Library and AF_Motor library are conflicting each other because LCD Screen is still White.
