[Others] How to read a 5V ratiometric sensor using a 1.1V fixed vref ADC?

The ACS712 outputs a voltage from 0-5V and the ESP32 ADC reads from 0 to 3.3V using 1.1V as vref. There is a voltage divider already to reduce the 5V to 3.3 range.The problem is: voltage drops on the power supply affects the ACS712 output. I consider that if it might work by using an external ADC with external vref tied to the 5V rail.

[Others] How to quickly reading GPIO pin LOW/HIGH directly?

I'm expecting to see the state of a pin that I'm reading to pull low for maybe 50 us and then back up to high. The original code running on an UNO/Nano code looks about like this:while (((PIND & 0b00001000) >> 3) == 1) { // busy } while (((PIND & 0b00001000) >> 3) == 0) { // busy }I've attempted this with th...
