I have some projects with Parallella board. I am going to use GPIO for handling some peripherials such as TFT TouchScreen driver, GSM Modules, I/O Controlling and I2C to communicate with some interfaces.
Recently i tested and I have some questions:
1. using para_setgpio doesn't let me put a "solid" signal at any gpio port. Instead of Pulse with proramm controlled lenght I do constanly get only a sigle pulse of 4-8usec (glitch)
2. same problem with Blink - i don't get a pulse of desired length |----------|________| i get |-|_______________ where |-| is "1" at desired GpioPort with length 4-8usec
3. function CParaGpio::SetValue does NOT insert all pins at once, But as before (1st and 2nd question) i get |-| pulse and for each bit next shifted |-|
4. How can I activate 2nd I2C port? /dev/i2c-1
I did not change anything at gpio_dir example. What should I do (idea, example ...) to get proper output at gpio?
Any answer would help allot!
Parallella is board I have waited for a long time,
