X-Sim PID - Moto Monster Edition Firmware
Copyright (c) 2014 Martin Wiedenbauer, particial use is only allowed with a reference link to the x-sim.de project
This firmware comes with a X-SIM GUI (Graphically User Interface = X-Sim Plugin) interface and easy setup interface to play around
with PID values. It is designed for users with less knowlege about programming and that want to simple upload and use the firmware.
After loading this firmware to the arduino, the firmware is detected in the interface setup automatically on any USB port.
Do not forget to clean the X-Sim Converter USO setup. If you have loaded another 3rd party firmware before, you might block the comport.
Same for the X-Sim Extractor OBD2 setup, remove the Moto Monster arduino comport from the list.
It comes with many additionally features like brake, 360°, GUI for pot scaling, power disable options etc. to get all the X-Sim features.
This program will control the Moto Monster Shield of Sparksfun, with a analogue pot feedback, compared to a serial target input value from X-Sim
You can get this H-Bridge easy and cheap from eBay.
Target is a Arduino UNO R3 but will work on all Arduino with Atmel 328.
This means, Arduino nano, micro, Duemilanove and UNO are tested. The moto monster shield does mechanically only be plug'n'play with UNO and Duemilanove, else you must wire it.
Arduinos with an FTDI serial chip need a change to lower baudrates of 9600 bit/s.
Read the below code and comment or uncomment the needed baudrate option with a double slash (//).
Help for wiring the Moto Monster Shield
Motor Pins (on Moto Monster Shield)
JP3 VCC - 12V from power supply
JP3 GND - GND from power supply
JP1 OUTA1 - connect to Motor A
JP1 OUTB1 - connect to Motor A
JP2 OUTA2 - connect to Motor B
JP2 OUTB2 - connect to Motor B
You may switch the two cables to the motor if you see that the feedback is not working (motor move in wrong direction).
Instead of switch the motor cable you can of course switch the +5V and GND cable of the pot which do the same.
If the motor control is working but you must change the direction, you have to simple switch pot and motor cables.
Analog Pins, must be connected not to the Moto Monster Shield but to a feedback pot connected to the motor axis
Pin A4 - input of feedback positioning from motor A, wire here the feedback pot middle pin
Pin A5 - input of feedback positioning from motor B, wire here the feedback pot middle pin
Other pot pins go to +5V and GND of arduino.
Important:
Do not wire a motor monster GND power supply pin with GND of arduino or the pot!
Use a heatsink on the VNH2SP30 chips on the motor monster shield. Maybe a fan is additionally attached.
Start with a low PWM frequency setup in the X-Sim GUI. The PWM setup is only for reducing hearable switching noise.
Pin out setup of arduino for Moto Monster Shield of SparksFun (needed only for programming and understanding code)

Si no va.. programo la nueva. Que comparando con la que tengo original... esta es casi clavada pero creo que es un clon.
Supongo que no importa.
Dime una cosa. Flasheo o le hago algo a la nueva? O le meto el sketch sin mas nada mas enchufarla?
Por cierto. El primer sketch que copie lo saqué de ahi. Me refería a que no encontraba mas por internet.
a ver si consigo que zumbe
Pd: 1000 gracias por la ayuda, por la paciencia y por seguir estando ahi.

Voy contando a ver.
Gracias!!
