TFTs / ILI9341 Command Delay
« on: November 17, 2014, 04:36:38 PM »
In the example code, unlike the datasheet, there is a TFT_Delay(10) after the command. I've found that my display does not operate correctly unless I have a delay. However, a response in this thread seems to indicate that the command delay is not necessary. If the a delay after a command is not necessary, what might be causing this issue? To be specific, when I omit the delay, the LCD skips some of the pixels that are subsequently sent and the pixels that are omitted are random. I'm running the application on a 48 MHz Coretex-M0.

My application requires displaying a grid, so I'm constantly changing the window with the page and row set commands. The delay required to send those commands is large enough that I'm only getting 1-2 FPS. I get about 10 FPS drawing to the whole screen without sending window size commands.

Thanks

Hi Sean,

My problem was that when I copied the example code, I had misinterpreted one of the signals, RS, as RESET. As soon I corrected that signal my problem was resolved.

EDIT: Fixed. Please ignore.

Was this ever resolved? I'm experiencing the same issue. I'm sending commands to the display, but nothing happens. The backlight is on, and the screen is blank. I'm using the example code on the website. Reading through this thread, I seem to be experiencing the same issues (although I haven't checked the current draw). I've tried two LCDs and two hardware platforms. Any help would be appreciated!
