Radiation Detection Circuit 1. First of all, you do not create files, but the class will do that for you. You will of course need to make sure that your hardware gpio is supported by the Linux kernel. Tachometer, etc, are different to a togglable GPIO. If the frequency is low 20Hz , you can do this from user space. Our header files are static or dynamic library 1. You could do something like the code below through sysfs as per the Linux kernel gpio documentation.

Equating complex number interms of the other 5.
You may probably have bigger problems with your Linux kernel. Dec 242: Post as a guest Name. Radiation Detection Circuit 1. Enabling GPIO through registers in FriendlyARM mini minii2440 I want to write to a physical address to change the voltage of a pin using an ARM board- but in order to write to a physical address, I need to take a virtual address, and map it to the physical address using mmap.

Why I am getting this substrate picture, when i create a new workspace? I had seen samples of your general purpose program and tried to write a C code for it myself.
Short circuit protection in PCB design 5. How this is related to your PWM question is unclear, but you seem to mix up two different kernel driver areas You could do something like the code below through sysfs as per the Linux kernel gpio documentation. How this is related to your PWM question is unclear, but you seem to mix up two different kernel driver areas Anyway, this class works fine for me and some other people.
How do you get an MCU design to market quickly? I think you missed that idea. Sign up using Facebook. Heat sinks, Part 2: Distorted Sine output from Transformer 6. Eagle PCB clearance error 2. Code C – [ expand ]. How to upload a counter value to a website automatically 3. More importantly, you have not provided any concrete errors. You need need to specify your imni2440 a little more clearly.
I really have no idea why you keep mixing up the two. What is the PWM frequency and duty cycles?
Access GPIO/PORTS in mini2440
Email Required, but never shown. How this is related to your PWM question is unclear, but you seem to mix up two mnii2440 kernel driver areas.
First of all, you do not create files, but the class will do that for you. I am almost certain if it is not closely hardware related it would be rejected in the Linux kernel.
