SONXUN SX8847

Hi all, I have two 240w dc motor driver for my flight simulator. Does anyone know them?
They are produced by SONXUN, SX8847 models.
I'm trying to connect to my Arduino Mega 2560 with two optical encoders, two limit switches and a proxy for the central location of the engines.
All for a cab game TAITO TOP LANDING converted to FSX!
An old 2DOF.
I will post pictures soon

@Ceresoli is there a data sheet available , a link with more information then we can inform you on how to use them.
http://forum.arduino.cc/index.php?PHPSESSID=me43bkmpcav26repgknmej1ch4&topic=134411.15
Looking here I found a code to drive them so to wire are run them he has :

//Functions used on h bridge pcbs.
int oneen = 8; // enable
int onedir = 9; // direction
int onepwm = 10; // pulse width modulation
int onedi = 2; // disable
//also connect GND and VCC obviously

Looks like we need to drive the enable pin high in order to enable the driver and then set a direction high will go one way and low will turn it the other way, then we drive the pwm pin inorder to set a speed to travel in the direction we want, lastly you can then disable the driver via another pin ( like if a safety switch).
Looks feasible and I believe @RufusDufus code could run these drivers.

Hope that gets you started

Thank you for reply!
I had already looked at the link you have posted.
I also found this, which also explains how to use the SPI register http://forum.arduino.cc/index.php/topic,171010.0.html
I can not find the code @RufusDufus . Could you give me the link? So I can compare with other material at my disposal and can then share my experiences. I would be really grateful!
Sorry for my english

Hi,
This in my Arduino's code for test only two SX8847 Without other I/O
I use it witw an Arduino Mega 2560 R3.

//Functions used on h bridge pcbs.

int twodir = 7; // direction MOTOR 2
int twopwm = 6; // pulse width modulation MOTOR 2
int twodi = 5; // disable MOTOR 2

// the setup routine runs once when you press reset:

pinMode(twodi, OUTPUT);
}

// the loop routine runs over and over again forever:

delay(1000);
}

Motors waits for one second, goes clockwise for 4 seconds, waits for one second,
anticlockwise for 4 seconds, waits for 1 second, repeats.
The setup routine runs once when you press reset

This is the first test of two sx8847 with Arduino Mega and one LCD.

Video ?

linked, sorry! i have edited the message

I have update arduino with an LCD. This is the first test.
I'm work to study the SPI register of SX8847, becouse there are some helpful function and communication sended to arduino from this driver!
The information are very helpful if the are some problem during motor control.
My idea is to have an LCD monitor 20x4 for parameter visualization like motor position, sx8847 problem (temp. warning, no load, undervoltage, ecc.) and state of various switch for security.
Very long work......

All coming along nicely, Well done keep us informed or any questions ask away.

Hello, sorry for my absence, but I became a father of the little Carol


I attach the datasheet of the integrated heart of sx8847 and the arduino's library found around the internet.
I hope can be useful, while I continue studying and compiling the sketch for the motor management

With a little help of arduino's community i have compiled this.
Example with explication for SX8847 SPI Access, program and serial monitoring
The second step is adding a LCD for diagnostic (visualize SX8847 Poblem and motor position) and complete the sketch with some security switch, 2pot and the infrared photocells that block the simulator in case of unauthorized acces in mition simulator area .
