Viessmann optolink TTL-USB adaptater
this adaptater is used to link your computer to a Viessmann heater via optolink. USB link will be made with a standard TTL-USB module.
I am having trouble with IR sensor. So consider si this projet as work in progress. I can't read any data from SFH309FA sensor. I don't know why. But I can read some signals from KY-022 module. But I won't be able to read serial data with this module. This module is used in 38Khz modulated signals. This is not the case in Viessmann heaters/controlers.
