[beagleboard] Re: Is there a GPIO status register somewhere?

POSIX type operating systems in general, including GNU/Linux, everything is done by reading and/or writing to a file. The GPIO "files" are in the "virtual" file system located at /sys/class/gpio. An example for header pin P9.14, which is GPIO 50: cat /sys/class/gpio/gpio50/value at the

[beagleboard] Is there a GPIO status register somewhere?

Hello! On a Beagle Bone Black Rev C is there a digital GPIO status register where I can simply read the [digital] status of all the GPIOs? or Is there a way for two or more separate programs to read-only monitor the same digital GPIO pin at the exact same time? I've looked through the PDF

On my quest to learn ROS and convert sami to BBBlue I'd like to try the turtlesim turtle_teleop_key on the BBBlue. I have the simulation working on the desktop machine. Now I'm building turtlsim on the 'blue. Looks like it wants the qtbase5-dev

I'm trying to set the bus speed for i2c-2 to 40. I'm running kernel 4.4.68-ti-r107 on a Beaglebone Black. So farI've tried 1. modifying am335x-boneblack.dtb to set the speed to 40 2. recompiling the kernel (after modifying i2c-core.c). in i2c_parse_fw_timings() i set

I've been having great fun playing with the BB Blue and the Strawson[1] robot. It's a pretty rugged little balancing bot. But today I have the first mishap. One of the encoder connectors broke off.
