Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello Harald,

There is a schematic at the following link: TFT-MM Schematic

Red LED (SC read/write) is on pin 94 of the chip - active when pulled to Gnd.
Buzzer is on pin 100 of the chip (MM pin D13) - active when high.

Neither has a pin number in MMBasic.

The buzzer can be controlled with the "TOUCH BEEP duration" command. The red LED indicates activity on the SD card and cannot be changed by a program.
