Programmable BenchPowerSupply

John All Messages By This Member #24218 Jack Me and my friends built the Programmable BenchPowerSupply , but we encountered many problems. 1 The touch display does not work. 2 The adjustment of the power supply does not correspond to the book. 3 if debug2 is not used the power supply will not start. 4 Ports are defined multiple times in the program (PB0). Is the" BenchPowerSupply004_Final_5-27-20 " the latest firmware. The book mentions a manual, but I can't find it. John on4ckf
jjpurdum Member Profile All Messages By This Member #24221 Hi John: I'm not sure why the touch display doesn't work, as there are thousands of the book sold and this is the first time we're had anyone say the touch screen didn't work. My guess is that the ILI9844 library is not being read. The line #include <ILI9488.h> ? ? ? ? ? ? ? ?// https://github.com/jaretburkett/ILI9488 gives you the URL for the proper download. debug2 is used to initialize the EEPROM. It needs the EEPROM to start properly. When the book was written, PB0 was defined in the core for the TeensyDuino software patch. Changes in the parsing done by the latest IDE enforces some C++ rules that were not enforced before and in the Teensy software patch has changed. I'm finishing up the T41 project right now, and it should be done in about a month. Remind me to look into this further after that and list any remaining problems at that time. The touch not working has to be a library problem, so check that out first.
