featheresp32-s2 does not work properly #815
Description
TLDR
Works on arduino IDE but not on platformio
I'm using a Adafruit ESP32-S2 Feather with BME280 Sensor. I'm trying to access the sensor using the i2c scanner
#include "Arduino.h"
#include <Wire.h>
void setup() {
Wire.begin();
Serial.begin(9600);
while (!Serial);
Serial.println("\nI2C Scanner");
}
void loop() {
byte error, address;
int nDevices;
Serial.println("Scanning...");
nDevices = 0;
for(address = 1; address < 127; address++ ) {
// The i2c_scanner uses the return value of the Write.endTransmisstion to see if a device did acknowledge to the address.
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0) {
Serial.print("I2C device found at address 0x");
Serial.print(address, HEX);
Serial.println(" !");
nDevices++;
} else if (error==4) {
Serial.print("Unknown error at address 0x");
Serial.println(address,HEX);
}
Serial.print("testing address ");
Serial.println(address,HEX);
}
if (nDevices == 0)
Serial.println("No I2C devices found\n");
else
Serial.println("done\n");
delay(5000); // wait 5 seconds for next scan
}
The platformio.ini:
[env:featheresp32-s2]
platform = espressif32
board = featheresp32-s2
framework = arduino
The board programs fine but the program does not find any of the sensors.
However using the Arduino IDE, and the board definition (Tools > Board > ESP32 Arduino > Adafruit Feather ESP32-S2) the program finds the two i2c sensors on the board as expected.
Another observation:
When programed through the Arduino IDE the programs prints the testing address xx lines all in one quick burst, (finds the two connected devices), then holds 5 seconds before doing another loop iteration. (ie. works as expected)
However when programmed using platformio the testing address xx lines print one by one in slow succession and does not find any of the connected devices.
