GPIO Open Drain

Postby berkutta » Sun Apr 17, 2016 9:03 pm

Hi community!

Is there any Documentation on how to set a GPIO Port to Open Drain? Couldn't find anything in the SDK PDF. Can anyone help me for that?

Thanks

Benjamin

Hi,

Please refer to the SDK/driver_lib/i2c_master.c, function i2c_master_gpio_init.

Thanks for your interest in ESP8266 !
