RE: Exp_Cropped Driver - Slow Catalyst - 07-05-2019

Ahh, that would make sense why I'm not seeing any changes after editing. Thank you.

So- just to be sure, in order to accomplish this- do necessary edits, and then do what to recompile and restart?

RE: Exp_Cropped Driver - Slow Catalyst - 07-05-2019

sudo pkill fbcp

and then

sudo /home/pi/fbcp-ili9341/build/fbcp-ili9341


RE: Exp_Cropped Driver - Porcinus - 07-05-2019

Yes but you don't need to restart for the testing stuff
Kill the driver using 'sudo killall fbcp-ili9341', by security, multiple times.
Then recompile and rerun it thru SSH

Edit: You have been faster than me loool

RE: Exp_Cropped Driver - Slow Catalyst - 07-05-2019

Killed driver, and restarted it through

Here is my waveshare.h

Just doesn't seem like anything has changed. Have I missed the recompiling bit?

#pragma once

// Data specific to the Waveshare32b display, as present on FreePlayTech's CM3/Zero devices (


#if !defined(GPIO_TFT_RESET_PIN)

// On FreePlayTech GBA devices, a part of the screen is hidden by the bezels, since the GBA has a 2.8" screen surface area, but a 3.2" display is enclosed inside the case.
// The hidden area is placed under the left edge of the display horizontally, and under top and bottom edges of the display vertically, so reduce those out from the drawable area.
// Effective display area is then 320-18=302 pixels horizontally, and 202 pixels vertically (in landscape direction).

// The meaning of top/left/right/bottom here should be interpreted as the display being oriented in its native direction (which is portrait mode for ILI9341, 240x320 direction).

sorry, replied between 2 messages

I don't think you can set negative value

RE: Exp_Cropped Driver - Slow Catalyst - 07-05-2019

Ah, that was me playing with values trying to get it to change before I knew the need to recompile part. I'll set them to 0 for now and then fine tune later.

You're a saint for all the help, man. I'm a total rookie in this area, haha.

So to recompile- I go back to this bit, and start from here?


RE: Exp_Cropped Driver - Porcinus - 07-05-2019

Yes, don't miss 'make -j'

RE: Exp_Cropped Driver - Slow Catalyst - 07-05-2019

On it now!

So I'm going to go to command line, out of ES.

Kill the driver.

cd /home/pi/fbcp-ili9341/build


make -j

sudo ./fbcp-ili9341

RE: Exp_Cropped Driver - Porcinus - 07-05-2019

I am really sorry, I need to get back to work, please keep us update Smile
This can also help others Wink
