Hi, OK, I missed it when reading the pot's documentation, my bad. Could you tell me what is the code for the SPI(x,y) function/library you are using on the BeagleBone ? I used SPI between PRUs and an accelerometer once, and I encourtered a similar problem, which finally came form the SPI phas

Hi, Is there a 2GB LXQT (or LXDE) image available for the BB-X15 somewhere, preferably Debian 8.x or is it better to start with a console image, and add all of the X packages (maybe something like the following FLIR Lepton example)? We have only 4GB of eMMC and looks like we need Xinit, X11,

So, I did want to point out that the toptechboy tutorial is not for the latest Rev of the BBB Wireless. In the latest, the hardwire Cat5 connector has been dropped, in place of all Micro- (no longer mini-) USB or WiFi connections. Pretty minor change, but you should know for your project. On Th

If I understand correctly, you are only trying to move 1 MB/s into SDRAM, which should not be a problem. You should do burst writes for efficiency, see the BeagleLogic code for examples. If you don't want to hassle with ring-buffers, you can dedicate a chunk of contiguous physical memory to your

Hi, AD8403 has a SDO pin (Pin 13). And my issue is in transferring the data to the pot. I meant to say, whatever value I pass to the pot, resistance is not changing. But when I use an arduino board, resistance is changing. Regards, Kaarkuzhali Murugan On Thursday, 8 February 2018 02:39:31

Have a look at the BeagleLogic project: they use one PRU for data acquisition and the other one to write to a portion of DDR allocated through a kernel driver: https://github.com/abhishek-kakkar/BeagleLogic/blob/master/firmware/beaglelogic-pru0.c On Monday, January 22, 2018 at 3:29:36 PM UTC, Da
