I can't remember the units of the ADC, it should be whatever is standard for Arduino. The processor runs on 3.5 volts, so readings will be referenced from there. Going from memory here, I think max range of that ADC is 1024 at 3.5 volts. The main reason for that battery read line is to tell when bat...

Hello ronaldroe,

They are basically identical, except we have take the external programmer board hardware from the first Ringo and put it directly on the robot - so no longer a need for a programmer board - just a direct USB connection to the robot for charging and programming.

Hello bigroad, There is no way to "reset" the robot, but it sounds like one of the motors isn't making contact with the surface. You may need to slide the motor down a bit in the clip that holds it. Just be careful of the wires going into the motor, and if you need to slide it upward, don'...

Man I'm sorry to hear the Pi is tearing up cards. I don't understand why it would be doing that. All I can think is that it is shutting down and dropping power before the Raspbian OS is finished halting. You can adjust the time the PIC will wait before pulling power with this function: PIC_SetShutdo...

Hello Astroghost, I got the code used for the playstation controller from a project called "Triangula". Here is the link: https://pythonhosted.org/triangula/index.html He was in process of updating the library and I was in a bit over my head when I was working on it. Basically it's a libra...

Hello rosborne,

I have sent you an email with more information and instructions. It does sound like that part was damaged. Let me know if anything is unclear in the email.

Thanks,

I've started updating the Spirit Code Reference with the UART setup. I've got a bit in there now, and hopefully will be adding to it over the next couple days. https://www.gitbook.com/book/plumgeek/spirit-rover-code-quick-reference/details There is a new entry in the Arduino Code section called &quo...

Okay I do understand your question. I have attached a sketch to this message. It isn't pretty - very ugly code I used in testing the Bluetooth module a while back. Large parts are commented out from other tests. Ignore all the FastLED and SPI port stuff, but this should at least get you started. I s...

Hey guys. Sorry it's been slow. I will make a real effort this week to at least have the instructions up to use XBee, Wifi, and BT on the main board. The main thing is understanding how the UART works as it is relayed through the PIC processor. Luunkaar - can you give me a better idea of what proble...

Hey everyone! I know I'm way late in this thread but I wanted to say I love what you all are doing. Sorry I haven't had more time on the forum here, but you all are doing an outstanding job running with this. Love it!

Thanks!
