ESP32-wroom-32E - GPIO34, something odd

I have a desingn that 12v is connected through a voltage divider of 15k and 4.7k, which calculates as 2.86v (and meters out as that) but as soon as i connect it to GPIO34, voltage drops to 2.1v (it still registers as a high level and the GPIO is on) but thats a lot of drop! code does set that GPIO a...

VSCODE ESP-IDF Ext - IDF menuconfig, White background!!!

im using the default DARK theme.. and its suddenly got a WHITE background, and grey text (very hard to read) i don't remember this being the case... i haven't programmed in a few weeks but now got a new ESP32 project... ESP-IDF ext version: 0.4.0 VSCODE 1.49.0 (just updated) Win 10 x64 2004 2020-09-...

Re: measure 9v to 18v

still researching...

R12 limits current into ADC so that if there is a turn on off the pins internal diodes (assuming it already has small clamping diodes)
its very low current... course with 150k R11 the current flowing should be tiny

Re: measure 9v to 18v

thanks for all the input... I wasn't aware of the issues with low voltage zeners would I calculate the voltage divider as 6.8v input? other thought: what do you think of the diode clamp? one of my thoughts was to do this protection id 1.jpg for sure i will average the value... what do you think is a...

measure 9v to 18v

Hi all, I want to measure voltage of a car battery... say between 9v and 16v with and ADC in the ESP32, can you recommend the input circuit to the pin? would it be a voltage divider then a Zener to make sure it does not exceed 3.3v? so like 39k + 10k then a 3.3v zener or maybe 2 diodes as a voltage ...

ESP-IDF-SDK Setup in Visual Source Code (1.23.x)

Hi all,

Im very new at this... but I got 1 issue... I got esp32 all set up in Visual Source code...
apps build just fine...
but

there is some intelisense issues... I get red squiggles on #defines from the sdk
(using the blink demo)
