even i work in Industrial Automation and Instrumentation ( and Electric )
( using so called Process Control Systems )
that what you think of
PLC Programmable Logic Controller
was never my thing,
but sure, some subcontractor used them and we linked them into the PCS via Modbus
you possibly come from here
about a project:
ARDUINO IDE / PICO W / WEBSERVER / MQTT NO TLS / NodeRed trend & DB & operation / 4 Relay board /
where i also try same code on the ESP32S3
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.
