Reading Battery and RP voltage from Nybble v0.2

Thanks Rongzhong,

I set the low voltage 'meow' warning to 6.5v, (2 * 3.2v min Li Ion level) by changing the 300 to 450

I have also created a new command to read the voltage dirrectly from the Nybble_v0.2 board.

in Nybble.ino at line561 after the

case 'a': {

PTLF("abort calibration");

for (byte i = 0; i < DOF; i++) {

servoCalibs[i] = servoCalib( i);

}

break;

}

I inserted:

        case 'v': {
            float voltage = analogRead(BATT);
            Serial.println(voltage/1024 * 5 * 3);
            break;
          }

Additionally,

So I could get access to the voltage while Nybble is operating, I updated the Flask API code https://github.com/leukipp/OpenCatWeb with the two following updates:

Update 1: in app.py after line 154, @app.route('/api/status/j/')

def api_status_j():

return jsonify({'status': {'j': serial.write(SerialCommand('j'))}})

I inserted:

@app.route('/api/status/v/')
def api_status_v(): 
    return jsonify({'status': {'v': serial.write(SerialCommand('v'))}}) 

Update 2: in bus.py after line 33,

if '\t' in line:

print(line)

return line.split('\t')

I inserted:

 if '.' in line:
     print(line)
     return line

Works like a treat. Meows when the voltage is getting low, and I can use the web API to measure the voltage usage as Nybble bounds around.

so many updates to catch up. I'm so sad that one of my packages from the US was lost and thus all my other tools and materials are held in the customs.

Hi @Rongzhong Li,

any plans to add the voltage status command into OpenCat.ino?

Will this also work with the new Bittle Battery?
