Just adding this comment to your project because from my google search there appears to be a number of people who have searched for an esp-idf based solution to driving this type of display which has been integrated into this board. Heltec themselves however only provide ardinuo based code. It is however very simple to get running, the key thing is a reset needs to be sent to the OLED display for it to start working.
