The problem I've had (it's the second shiled that does this) is it stopped comunicating, suddenly with no reason.
I've been using it for some time without any problem and then I tried to load a new program and just didn't work.
For instance I use a S-120-12 power supply (output: 12V DC and 10A).
I'm using the software serial with TX in pin 3, RX in 2 and control in 8. (tried with PINs 11,10,8 and the same ocurred)
Theres nothing burnt or anything (at least that can be seen) nor is it too hot while working with it.
Using default cytron_g15shield library it gets error when trying to communicate:
- Ping: overload error
- Set wheel mode: overload error
- Set torque on: overload error
- Exit wheel mode: range error
The error is read by serial port but theres no led blinking in the servo. (tried with PINs rx=10,tx=11,control=8 and other combinatios and the same ocured).
As I connect the servo, if theres no power supply on it makes that sound (tac tac tac) as it's no getting enough fuel, but it stops as soon as the power supply is connected. I assume theres no problem with power.
Any idea of what could be happening? It's the second shiled that goes away with no reason I can guess.
Thanks in advance!
