A while ago I made this radar toy. In my old way. I would like to adapt it now with the HCRS04 lib. I use the 16F877a and I tried to convert the sample for this. Of course I can't do that again. Is it too much to ask to adapt the sample of 16F1827 for the 16F877a? Greetings Hans https://youtu.be/kBK_Qo-Y4js
