 All right, what's this this is a blinking LED now, it's a blinking TFT This is a round 2.1 inch TFT And I just haven't turning on all the pixels white and off and the reason I'm doing that is I'm actually trying to debug this Which is trying to get the large four inch screen working with the ICN-6211 and it's not working And I don't know what's up And I think that's due with this screen initialization Which happens over SPI, but the problem is I've got Raspberry Pi, kernel, device overlay, ICN configuration, SPI configuration, ATT, there's too many variables So what I do is I'm actually testing this up first on a known working platform Because I'm always like start with a known working thing change one little tweak to you know, figure out what's going on and then Adjust and adapt until you figure out exactly what your root cause is and I actually don't have the ESP generating any TFT signal what I'm just doing is the SPI configuration and if you look over here on the The data sheet Sorry all pixels on there you go There is this mode called all pixels on which will turn on all the pixels for you and you don't have to have TFT signal It just does it directly from The SPI commands and so over here what I've got is a little bit of code that sends the init sequence init sequence But then it appends to the init sequence the command to turn all the pixels on and off And so now that I know that that init sequence is good I'm going to move that code over to the ATTiny over here And that'll let me know whether I've got the SPI init code and wiring working and then I can work backwards fix the ICN fixed advisory overlay and basically get it all working with a Raspberry Pi
