clarkwise ATFC touch screen advance settings:

In each clarkwise ATFC touch screen module, there is a text configuration file called “TFTcfg.txt” saving at built-in storage.

This is a critical file. A lot of important settings are inside. Advanced users can change some settings with Notepad or any other text editor.

The useful settings are:

SettingExplainationDefault Value
UART_SPEEDUART baud rate (bps)9600
TFT_LONGKEY_WAITHow long if a user pressed a button to trigger “Long Key” mode. The “Long Key” is a button repeating output. (ms).
Set it to less than 800 to turn “Long Key” mode off.
