I2C does not pull up. #8

Closed u26 closed 1 year ago

u26 commented 1 year ago

When I run Wire.begin(); sda,scl pin looks not pull up.

I checked source code variant.h and pin 11,12 is used to i2c sda/scl. so I connect the i2c device to pin 11,12. but does not work. thanks.

static const uint8_t SDA = PIN_WIRE_SDA;
static const uint8_t SCL = PIN_WIRE_SCL;
