revive NODE MCU ESP32s & Arduino IDE 2
Posted by kll on March 03 2025 07:09:30
test if i could run my current big project from ESP32S3 also on a ESP32
i try on that, even after jumper the cpu temperature thing ended in kernel panic auto reboot
but i noticed that this ESP32 i have, has 2 DAC pins ( Analog OUT )
a rare feature i want use.
Extended Blog
for this
NODE MCU ESP32s
need to install a USB driver on ( fresh setup ) windows 10 PC
from here
CP210x_Universal_Windows_Driver.zip
unzip
run silabser.inf
and i forget, need to press right button
( right of USB plug when WIFI Antenna is UP )
for compile download while it shows
connecting ...
press until see
writing..
DAC
so i play with same code about DAC_1 (25) to A0 (36)
dacWrite(25, val);
int A0i = analogRead(36); //get A0
float sensorA0val = in_volt(A0i);
sprintf(buff," A0 %4d , %.3f V",A0i,sensorA0val);
Serial.println(buff);
Signal Generator
now start with webserver code, same style actual projects ( new button HTML style )
now i will test it over at the
PICO 2W project PMS1W
but i try to combine that old hardware
with my actual project and it works.
but for a short test
ARDUINO IDE / ESP32S / HIVEMQ
i recommend NODEMCU32s_HIVEMQ_ino.txt
and now try a next step in that project:
use a ACS712 Hall current sensor on A0
