Hi
I have a µLCD 32032P1T which I want to put into sleep mode consuming the lowest current. How can I do this ? I'm using the SPE_alpha01.4dg file which I adapted to my needs , but using a backlight off , a power down and contrast to 0x00 still consumes about 100mA !!!
I think this could be much less , saying a few mA's ?
I also read somewhere that the used controller is a ILI9320 so I added this code from their app note :
display_SetReg(0x07,0); //Power down the lcd into deep sleep mode
display_SetReg(0x10,0);
display_SetReg(0x11,0);
display_SetReg(0x12,0);
display_SetReg(0x13,0);
pause(200);
display_SetReg(0x10,2);
But still same result
Who can help me on this ???
Kind regards ,
Ronny

try: sys_Sleep(0); Using '0' as the input argument will result in the need for a "reset" to get the screen to wakeup. another way to do it, which is what we do, is to sleep it for say 10000 seconds or more, that way a "touch screen" press will bring it out of sleep and it will continue processing code. ie sys_Sleep(60000); Goodluck Andy
