Hehe still here Chris just busy and lazy lately, you know what happen to just married people:-) will work something out soon

The driver works perfectly, however you need to calibrate your XL5 to the proper timing settings.

EDIT: Also, you cannot use that shield for that motor. You need a proper ESC.

BTW: Fancy seeing you here, Hai, I wondered what happened to you.

my guess the answer is yes and no...you should be able to get rid of the ESC, and control the motor via that L293B motor shield, that is what the shield is for anyway.... however you are going to have to replace that Titan 12T with something else, this motor draws around 20-25amps of power while the according to L293B only output 1Amp, so you dont want to BBQ the shield. I assume you drive the gearbox with one motor? so consider replace that motor with something less powerful (around 1amp). at the sametime it has energy to drive the gearbox. something like this one maybe, (specs from ebay) •Model RS-385-SH-2270 •Operates on 12 VDC nominal •Operating voltage range: 6VDC to 24VDC •No load speed at 12 VDC is 10,000 RPM •No load current is 200 mA •Full load (maximum efficiency @ 12VDC) performance characteristics: ◦Speed: 8,170 RPM ◦Current: 890 mA ◦Torque: 80.5 g-cm (7.89 mN-m) ◦Power output: 6.74 Watts •Stall torque: 440 g-cm (43.2 mN-m) •Stall current: 4.00 A

Chris,
Good to know how to erase, but if you were lazy like I am, mine got stuck nemerous times, simply unplug the USB cable while it is stuck and replug back in, wait for all driver loaded up then try again, that will alway work for me too.

This is not just NetDuino issue but FEZ also has this dissease, I guess microsoft vs and hardwares team are still having some small problem understanding each other...

Thanks!

Thank you for the information I will look into when i arrive at my new home.

I guess you got the answer, but here according to tech specs:

● input: 7.5 - 12.0 VDC or USB powered
● output: 5 VDC and 3.3 VDC regulated
● analog reference: 2.6 - 3.3 VDC
only required when using ADC features


● max current: 8 mA per pin
digital pins 2, 3, 7: 16 mA per pin
analog pins 0-3: 2 mA per pin
microcontroller max current: 200 mA total
● digital i/o are 3.3 V--but 5 V tolerant
