Re: RaspberryPi sized touchscreen MI0283QT

I think the connections made by D. Gallot are correct. In addition to the connections listed in the page, the lcd adpter's "IRQ" pin needs to be connected to the RaspberryPi's "GPIO17" pin. Otherwise a touch on the screen would not be detected. Before you try to use my drivers which are a little ela...

Re: RaspberryPi sized touchscreen MI0283QT

Still, I have a problem with getting the touch interrupts to work correctly. The cursor doesn't quite point to where I push with my stylus. Did you calibrate this in any way? No, for my case that wasn't needed. The default margin values fit the display quite well, I only used fingertips however, so...

Re: RaspberryPi sized touchscreen MI0283QT

It was made to be attached to a RepRap 3d printer as user interface. That is almost completed.

However, any animation or movie displayed would be updated far to...

Re: Motion detection on GPU with the CSI camera module?

Simple motion detection with the GPU can be done with OpenGL ES. Outline: 1) Make a simple framework that renders a quad to a texture. This way you can use a GLSL fragment shader to do some calculations to a lage block of data. 2) Prepare three textures 'source', 'background' and 'result' 3) Do a ca...
