Re: [QUESTION] SPI and PSP 2-Axis

the 2 axis stick gives an analogue value, the SPI based Digital to analogue converter changes the signal into a digital reference that is taken back to the pi via the SPI bus. there are many 2 axis sticks that do the same things, I've got three in my bits box waiting for a project that needs them. ...

[QUESTION] SPI and PSP 2-Axis

Hello, So, I'd like to know if anyone has any information about the functionalities of PSP 2-Axis in the Raspberry Pi? I want more detailed information than this site http://www.newsdownload.co.uk/pages/RPiGpioPspAnalogJoystick.html, because I can not find nothing about this usage. I appreciate your...

Re: Qt 5.3 RC - Framebuffer window oversized

I chose to reduce the size of the webview instead of trying to change the framebuffer itself. https://github.com/Topguy/mlbrowser/blob/master/src/mlwebkit.cpp I've tried every method of QWebView and QDesktop, and the resize doesn't work. I was tried the same of yo...

Yes, I wish. It's a problem to me, today... actually in the last weeks. I've been working on my graduate project and I need to read the information of the gpio, that I'm using to do this the onoff (nodeJS), without to make a socket connection, I'd like to do this directly, like a shared memory or so...

[RESOLVIDO] Por quê não conseguimos fps elevado em modo SPI?

Olá pessoal, Então, como o título já diz, por quê há essa dificuldade em conseguir altas taxas de fps utilizando um LCD conectado diretamente ao SPI/GPIO? De antemão, descrevo a minha situação: estou desenvolvendo um video game portátil como TCC e até o momento, tudo que venho encontrando sobre LCD'...
