which are the units that apeears on the .txt file in the channel of the battery? I mean, the column that represents the battery level (channel 6 in my case) is a number around 580 or 570 (that represents the battery level of charge, isn't?) How can i translate this number into voltage units?
The transfer function for the battery should be as follows:ABAT [~3.4 V : ~3.8 V]ABATV
- 1))Where: ABATV
– Battery level in Volts (V
– ADC value for ABAT obtained from BITalinoVcc
– Operating Voltage (V
– number of bits (bit
) Values: Vcc
= 3.3 (V
= See Number of Bits section Number of Bits
: The number of bits for each channel depends on its position in the "acquire channel" request (ex. BITalino().start([0,2,3,5])):
- If it is one of the four initial channels, its resolution will be: 10 bit
- If it is one of the two last channels, its resolution will be: 6 bit
