[beagleboard] Re: Official eQEP driver Support

Hi all, I'm trying to use the eQEP Linux driver. I can get it to load by adding a device tree overlay, but it doesn't increment much. I can see that its loaded (called tieqep) with lsmod etc. I've never used a quadrature encoder before, so I question if I just havn't connected it correctly.

[beagleboard] BBB device tree compile

I am using Debian 4.6.3-14 and trying to compile a brand new device tree (the entire thing, not just an overlay) and I am getting errors trying to use the dtc functions. I read that it may be possible to use the make function to compile the device tree but have not seen anything specific to

[beagleboard] Re: As much as possible GPIO Outs . What should I do ?

Depending on how fast you need to control and respond to the GPIO, it may be easier to use the I2C bus and control some GPIO expanders. A chip like the PCA9555 will get you 16 each GPIO, and you can control 8 of them on an I2C bus. If you need more GPIO than that, you can buy other parts that

[beagleboard] eQEP1 setup problems with latest debian iOT

Following on from my earlier messages related to this, I am using cape-universal now to setup and control the pins for my mechatronics project. Pinmap constraints mean I need to use eQEP1 and eQEP2. eQEP2 on P8_11, P8_12 and P8_16 is working, but I can't get config-pin to setup eQEP1 on P8_31,
