So I picked up an ACS70331 based sensor from seeed. Using the internal ADC of the ESP8266 board (10 bits) and some code provided by the ACS board manufacturer with some tweaks I am … WebNov 28, 2024 · On the first screen: I read the values of the registers from the ADS1115. On the second screen: I showed that the ALERT/RDY Pin is always low. I think it should be like this: at the first point: set = 500000; reset = 0; at the second point: set = 3100(8ms), reset = 496900; at the third point: set = 500000; reset = 0;
