When using switches, numerical displays, and other controls, if touch is enabled in the control permission settings, select bit control or user-level control. When you download the program to the touch screen, you will see a red prohibition sign on the control.
Remove the Red Prohibition Symbol:
Open the software’s help menu.
Find and open the System Reserved Registers.
Locate the address LB3985, which is used to cancel the red prohibition symbol.
Write a Macro Instruction to Set LB3985 to 1:
Open the macro instruction compiler from the software’s extended toolbar.
Click “New” in the macro instruction compiler’s menu bar to create a new macro instruction project.
Write the following macro instruction: plaintext LocalBit[3985]=1;
After writing, click “Compile”. Once the compilation is successful, add the macro to the global macros.
Download and Test:
Download the updated program to the touchscreen.
Check to ensure that the red prohibition symbol has been removed and that the touch control is now functional.
