M5Atom I2c

Hi all,
i'm playing with the mpu6886, with the Arduino lib i can read it.
how can i use the "grove" connector (g26,g32) with a i2c device at the same time?

thx Michael

ok...i find out that i have to use SoftwareI2c and the i2c device must have pullup resistors:

#include "SoftwareI2C.h"

SoftwareI2C softwarei2c;

void setup() {
Serial.begin(115200);
softwarei2c.begin(26, 32); // sda, scl
Serial.println("begin to scan...");
}

void loop() {
for (unsigned char i = 1; i <= 127; i++) {
if (softwarei2c.beginTransmission(i)) {
Serial.print("0x");
Serial.println(i, HEX);

        while (1);
    }
    softwarei2c.endTransmission();
}

Serial.println("find nothing");
while (1);

}
