    noise on ADC when using LM2596 (~1600Hz)

    Hello, I noticed that I have a periodic noise on the ADC's, when using the LM2596 switch mode power supply (period is 5 samples, so ~1600Hz, signal varies +/- 6%). When powered over USB, the noise is not there. If I attach the LM2596 at 7V to the Vin of the Arduino (and thus is applied through...

    bug: robot never switches off if battery is empty

    I just found that the in the Robot::checkBattery() function, the test sequence is wrong. First it checks if the batVoltage is below batGoHomeIfBelow. if not, it checks if it is below batSwitchOffIfBelow. However, the latter is lower than batGoHomeIfBelow, so it will never be checked. Either the...

    calibration issue with ADCMan

    Hi, I found an error in the calibration procedure of the ADCMAN. While calibrating, and if the sample size is set to 1, the measured value is not stored in the sample array, and hence the offset is set to an arbirtrary number (typically, the measured value with the previous offset applied)...
