Question
TFT LCD touch screen mapping by external keypad
Posted on July 12, 2018 at 07:02
Dear every body,
I'm doing project about lcd tft 7inch 800x480 and stm32f746.
Currently, i want use external keypad (or external button), not use touch screen pannel.
Example:
http://hshop.vn/products/ban-phim-ma-tran-mem-4x4
I have 1 button on LCD:
// { BUTTON_CreateIndirect, 'Browse', ID_BUTTON_0, 13, 8, 100, 20, 0, 0x0, 0 },
(x,y) = (13,8).
width = 100.
height = 20.
=> (x,y) center = (13+100/2 = 63,8+20/2=18).
When 1 keypad or button pressed, i checked that ok.
How to mapping 1 key pressed to WM_NOTIFICATION_CLICKED event of
ID_BUTTON_0 (ID_BUTTON_0 is displayed on LCD)? After that, emwin will do something: show dialog...
Can you tell me solutions, please?
Thank you so much!
