Çinliler sağ olsunlar elektronik malzemeleri çok ucuza satıyorlar ama satış personelleri teknik açıdan sattıklarının ne olduğundan bihaberler. Hiçbir teknik destek alamıyorsunuz.

Display speed – LCD and TFT (with STM32)

You must know the display speed, if you intend to display things while your process is running.  Displays are generally slower compared to your uC and other similar processing components. Ignoring the time needed to display your data may result in failure. In cases where you implement interrupts in your process, this issue becomes more complicated.

Accessing Touch Panel resistors of a TFT Display

2.4″ TFT DISPLAY TOUCH PANEL RESISTANCE TERMINALS  
How to find and use them (FOR NON ARDUINO USERS)

Chinese made TFT Display !  You can not get any support, but low cost compensates that. Here is the help !

2.4″ TFT ekran, dokunmatik

Terminals of two touch sensor resistors, one in X other in Y direction are connected to 4 pins of screen. These pins are shared with TFT display signals. Life is easier for Arduino users who just plug and go with “Arduino compliant” products.

Whereas, non Arduino users like me have to find out which pins are used on their TFT TP.  Since I am a STM32 user, I had to find out my own way.  I share it below for interested ones. Hope that will be helpful for someone. Continue reading “Accessing Touch Panel resistors of a TFT Display”
