Kako izgleda logging https://pastebin.com/nHwJAEXD , primecujem da treba da podignem jos vise sampling period na ads1115 jer ovako sam premasio vreme koje treba da bude u tom jednom zero cross ciklusu dok se radi merenje temperature.

Code:

                        LOG("Conversion: buf[0]=0x%02x buf[1]=0x%02x combined=0x%04x time=%.2f mS result=%f temperature=%.2f\n",
                                 buf[0],
                                 buf[1],
                                 val,
                                 (float)((gpioTick() - prev_tick) / 1000.0),
                                 (float)(val * (2.048 / 32767.0)),
                                 temperature);

Dodatno undervoltage ikona na ekranu, napajanje nije ok, to prvo resavati pa tek sve ostalo.

Inace ovo sam juce pazljivo podesio:

BSC0_FIFO = 0b11000101; // start conversion, AIN0 and GND, FSR=2.048, single shot mode
BSC0_FIFO = 0b10000011; // 128 SPS, Traditional comparator, alert pin active low, nonlatching comparator, disable comparator, alert pin high impedance

Podesio sampling period na 250 sps, sad ovako sad izgleda:
BSC0_FIFO = 0b10100011; // 250 SPS, Traditional comparator, alert pin active low, nonlatching comparator, disable comparator, alert pin high impedance

A i log koji potvrdjuje da je sa 250sps tajming ok ali i dalje ogroman noise https://pastebin.com/Pbnthn8i
