How to decide which analog port to use (male/female)

[chetanpt]

Hi

I am using pin 35 to read fsr sensor data. FSR sensor is connected to female port.
I do not receive any data on female port whereas on the male port .

How to we decide which ports to use and how to change that.

I am using arduino ide.

Thanks

They're the same

@tobozo
Thanks for the information

In my case female ADC pin does not get data whereas I receive data on male ADC pins.

So my question is how do I resolve this, so that I can receive data on both pins without worrying ?

Thanks

Could it be broken ?

Hi

In my case every alternate day the M5 stack does not receive data. It always shows 0.

I use following code on platformio

#include <M5Stack.h>

int fsrpin = 35;
int wristforce;

void setup() {
// put your setup code here, to run once:

M5.begin();
pinMode(fsrpin, INPUT);

}

void loop() {
// put your main code here, to run repeatedly:
M5.Lcd.clearDisplay();
M5.Lcd.setTextColor(RED);
M5.Lcd.setTextSize(3);
M5.Lcd.setCursor(15, 15);

wristforce = analogRead(fsrpin);

Serial.println(wristforce);
M5.Lcd.print(wristforce);

}

M5.update();
delay(500);

}

Hi @tobozo

I found the root cause after troubleshooting and searching on google

I connect my FSR to 5V but the 5V pin is not predictable sometimes it give ~ 4.5v and sometimes it does not. I do not know the reason.

But the 3.3 v and +ve terminal of grove connector (~4.5v) are more reliable, I think.

Thanks for your help
