gpio

I'm trying to use GPIO functionality provided by nct5104d chip on the APU board. I have installed FreeBSD 11 with nctgpio and gpiobus modules loaded. However, when I'm trying to run gpioctl, I'm getting an error message, and no GPIO device exists in /dev: root@apu-freebsd:/usr/home/conveyor #...

Hi! I use RPi B (early release) and FreeBSD 11.1. I use gpioctl to see GPIO pin states and I see, that GPIO pin 6 has OUT state and 1 on it value. According to this - http://elinux.org/RPi_Low-level_peripherals#P1_Header_pinout.2C_top_row GPIO 6 is the ground pin. How it's possible? Or my...

Greetings, Colleagues! Tell me, please, what I/O cards with GPIO-like contacts are supported by FreeBSD. They are also called binary I/O cards, relay-cards, lab-cards, and so on. As a rule, they are used in science, in the management of industrial systems, in different monitoring complexes...

I was wondering how well the zoneminder port works? What is a reasonable amount of cameras it can support? I am using Arecont cameras 5MP with the Arecont Windows software and I want to make the switch to FreeBSD. I have one installation with 8 cameras and one with 12. I have a couple at home...

A couple of years ago, I bought the SunFounder Basic Sensor Kit for Raspberry Pi which includes sample source code for various projects. It is obviously geared towards Linux, but should I expect to be able to compile some of the examples on FreeBSD?

Does anyone have any recommendations for a solar charger for a RPi?

Is there anything like a list of projects that can be attempted using FreeBSD on an RPi? I'd like to know how to do simple things like switch lights on and off for a start. I do have a PiFace Digital board - (that's version 1), but I've never really done anything with it, not understanding...

Got a APU3 from PCEngines directly. Testing the GPIO to see if they used the same GPIO chip and base address as the APU1C. I loaded the module and it looks good. Working GPIO on another amd64 platform. kldload nctgpio or /boot/loader.conf nctgpio_load="YES" root@APU3:~ # sysctl -a | grep 'gpio'...

Looking to learn a web frameworks. I want opinions on what to use. Today I bought some books on python. I want lightweight for embedded usage and I am leaning toward Pyramid. A fellow user here showed a nice Ajax and Python interface that impressed me.. So many choices even within the python...

I have some Dallas One Wire Temperature Modules that present a sysctl interface that I would like to display in a GTKwindow on a RaspPi2. Looking around I found this function: sysctlbyname() which seems to fit the bill for dev.ow_temp. I am finding few examples but this seems the best but is 10...

Been looking at tutorials and source for One Wire gpio and I am wondering if anybody else is using this work? I bought a dozen DS18B20 temp sensors to mess with. The source notes for /sys/dev/ow/owll_if.m has to be the most elaborate source documentation ever. Bravo Warner Losh

I am interested in this GPIO Library. Stupid question. I can't read code yet. What language is the example using. https://www.freebsd.org/cgi/man.cgi?query=gpio&apropos=0&sektion=0&manpath=FreeBSD+11-current&arch=default&format=html

MINNOWBOARD TURBOT LSE EXPANSION HEADER TO BYTGPIO.C DRIVER PIN TRANSLATION Minnowboard calls thier 26pin expansion header "Low Speed Expansion" pin 1, pin 25 and pin 26 are marked on board. This device uses three gpio busses. gpioc0,gpioc1,gpioc2 I had to turn off several settings in the...

In the moment I got some Data Acquisition Installations running FreeBSD 11 on Intel Atom boards using National Instruments PCI boards for A/D, D/A and DIO. I am looking for alternatives which would be less expensive and perhaps somewhat smaller in size, so I could eventually embed the computing...

Support was added to FreeBSD 11 for an x86 boards GPIO pins. PC Engines -APU1 using the Nuvoton NCT5104D with a driver named nctgpio.c I could not find instructions so here is what is needed: kldload nctgpio or nctgpio_load="YES" in /boot/loader.conf To check pin status: gpioctl -lv To set...

Gonzo has added Baytrail GPIO support. This guy is truly a code master. https://svnweb.freebsd.org/base/head/sys/dev/gpio/bytgpio.c?view=markup&pathrev=308295 This has been tested on the Turbot and should work with Intel Baytrail platforms that breakout the SOC GPIO's. This has truly elevated...

Hi guys. I just wanted to get your opinion on the best dev board to run FreeBSD on. I have a project I'm working on where I pretty much just need GPIO, (wired) networking, and the ability to run a Java program. My boss bought me a couple of Raspberry Pi 3Bs, but I can't seem to get anything...

I started work on a GPIO driver and got it roughed in. Aiming for SCH3114 on Advantech boards. Figures, I find this similar Nuvotron driver after I guessed my way through alot. It is nice to see the proper way to proceed for review: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207405 So...

This is an interesting kickstarter-funded board that seems to be running late. Imagine that. http://www.up-board.org/ I like the specs.

Howdy, I am wanting to learn GPIO's on FreeBSD and I need advice on hardware. I have 3 platforms that have advertised GPIO's for I/O use. MinnowboardMax Turbot, Advantech PCM9362 and Nexcom VTC1000. None seem to have a working GPIO found. I have searched the forum here and looked at the docs...
