have you tried to load EasyLoader example from M5Stak product page?

have you tried to use M5Burner and "erase" option first? have you tried to load any simple Arduino code? or any available EasyLoader project from M5 product page?

open M5 burner and burn latest firmware to it

are you able to send any uiflow created code to your m5stick?

cable is well hidden in Tab5 box, good to know you found it

did you looked here by chance?

M5 watering unit

do you use m5burner?
if so what com port it shows there when you connect cardputer?
also what com port it is showing when cardputers on/off switch is in off and then you press and hold BOOT btn and then connect usb?

It depends on how it feels, sometimes it will connect on Com 4 and other times on Com 9???

thing is that comport you see with just connecting cardputer to usb is one of two available

second comport (needed for programming) is visible when on dead device you press and hold boot button G0 and then connect to usb

for start: what hardware do you have for this task, are you able to update firmware via M5Burner to your controller?

its easier from inside - just undo nut - than using screwdriver in "bolt" flat slot from outside

press and hold red button then slide it out

just connect voltage to sensor and measure what voltage it is giving out between output pin and ground. for 0 kPa your raw Analog value should be around 1300 i think

with your raw value as 3287
sensor range -100 to 200
analog range 0 to 4095

your calculated pressure should be around 140

what are RAW values you are getting from your sensor? pure analog read value?

try below

float raw = analogRead(sensorPin); // Read analog value
float Vout = raw / 4095.0 * 3.6; // Convert to voltage (assuming 3.6V reference)
float P = (Vout - 0.1) / 3.0 * 300.0 - 100.0; // Calculate pressure in kPa

@Kenzo as Ive said before try below: remove "get voltage" block and try your Tube Pressure unit with analog value only

try with analog value, delete get voltage block

on your original "tube pressure" example use raw analog value for start too

ports in general are configurable, some units have just one general port which can be analog, uart, I/O, i2c.... try to build project with diff analog sensor (even without this being connected) like potentiometer unit or something...
