There is wrighten there in no software support for this port so how do You use it for example to make a led blink ?? Is it possible without master programing skills ??
Use Ryleh's Minimal Lib: Here the function to callOrange Pumpkin said:There is wrighten there in no software support for this port so how do You use it for example to make a led blink ?? Is it possible without master programing skills ??
The lib is for the gp2x, the wiz is different hw. Ryleh is currently making a new lib that should be supported by the wiz.Orange Pumpkin said:Thanks , will wiz have the minimal Lib .. I know that it wont have the SDIO but just the lib ??
Orange Pumpkin said:I read some of it and I see that the main problem is that I would have to wright my own drivers ..
Is it hard/possible to wright them ??
Depends for what hardware - your own that just blinks a LED, should be easy. Trying to get a SDIO Camera to work would typically be much more difficult (as it wouldn't be documented).
As for the voltages, no.
Don't know about the Wiz. I don't have one.
What did You mean ??Orange Pumpkin said:QUOTE

Orange Pumpkin said:Becous it is not fully open ( I think , becous for example the 18 + thing in the Wiz and no hard-ware schematkic ) but if You say that's enought , Ok I think after some time mb I will buy GP2X or Wiz ..
GPH don't care what you do with your console. There's no hardware schematic because they don't want people ripping off there console and selling it cheaper than they do (which is a moot point now as it's a discontinued product anyway).
All GPIO ports are strictly VCCIO or GND, nothing in-between. You may be able to re-purpose the SDIO pins as GPIO, but I've not tried that. Even if it is so however, you shouldn't expect them to have the current handling capability of a LED. They are meant as data communication pins, assume 2mA unless you read somewhere they'll handle more.Orange Pumpkin said:Happy new Year ( In my country ( Poland ) it pased 3 h and 19 min ago )
Ohh and conserniing to the voltages I wanted to ask about the GP2X GPIO port conected to the led , are there any drivers like that above but with voltage changable
Happy new Year.
