I tried to power the ATtiny13 from the onboard 3.3V. The data, as you could see, comes in 1023, 666, 10 format, well, at least take it and save it in CSV format on a computer or another device that will receive this data.īy the way, the data in my case is an inexpensive USB to UART converter based on the PL2303HX chip. R1 is not critical, but according to the rules of "good tone" - must be present. It would also be not bad on the capacitor to each port of the ADC, and as close as possible to the MK. ![]() ![]() I will say right away that it would not be bad to pay attention to the power filter, I have two C1 capacitors - preferably “ceramics” and as close as possible to the legs of the MK, well, C2 is electrolytic, the second one can be set to 100 μF, but I didn’t have this under hand, found at 470 uF 10 V.
