Teensy4.0 new macros .. #229

Closed jox1a closed 1 year ago

jox1a commented 1 year ago

Hi all I wrote a new macro for T4.0 However, it does not work, probably somewhere there is a mistake that I do not see. Maybe Someone with More Experience Can Have A Closer Look and Tell Me What Is Wrong.

Thanks.

new macro works well T4 + Open smart 3.0" R61509v should work fine with other TFTs feel free to use``
