Grove Project

WA2ZKD · December 2017

I started working on my Grove project. It will use the BB Green Grove connectors to manipulate external devices such as an antenna matrix. Part of that required a peek at the /boot/uDev.txt file. Does that file get modified when a kiwi update occurs?

KA7U · December 2017

I took a look and did not find your /boot/uDev.txt but I did find /boot/uEnv.txt. That file enables capemgr for various capes, it would seem. Don't know if the KiwiSDR software edits this file or not. These are the only active lines in the file on my KiwiSDR.

uname_r=4.4.9-ti-r25

cmdline=coherent_pool=1M quiet cape_universal=enable

cape_enable=bone_capemgr.enable_partno=BB-SPIDEV0

uuid=edfcb0d5-8128-41ef-a56c-ba206238018c

So I doubt the KiwiSDR software is writing to this file with each update, but maybe it does.

So tell us more about your layout for using the Grove project. Is it this kit, http://wiki.seeed.cc/Grove_Starter_Kit_for_BeagleBone_Green/ ?

my typo! Thanks

Regarding the grove kit, no. I bought individual pieces from Mouser, a selection of stuff but not much money. will surely report!

I am using this module to test Grove with and figure I can mod one to use as a relay driver http://wiki.seeed.cc/Grove-Chainable_RGB_LED/

Further........

It looks like it is easy to convert the Grove-UART connector to act as GPIO. Some typos in the examples on webpages is thwarting me at the moment.

The Kiwi code does not modify /boot/uEnv.txt but instead uses an older method for setting up the GPIO pins it needs.

Be very careful when editing that file. Make a backup copy in that directory. Certain mistakes will brick your Beagle. And the recovery method is annoying (USB or serial cable needed).

I have found this and need to explore it some more. I have extra kiwis here so won't jeopardize my online one if I mess up!

After installing seeedgrove from a .deb, this now runs and the Kiwi is still alive. Now i just need the right grove module

Searched and found this, will be helpful

I have another version of that table that covers all the Beagle P8/P9 pins if the Grove UART pins are not on there.

There is a similar one in the BeagleBone Black system reference manual (SRM): System Reference Manual

You should be able to figure out how to manipulate the Grove I2C/UART ports using Linux commands with the Beagle GPIO interface in /sys/class/gpio.

There are tutorials on the net about this I believe.

Then you could add those commands to another instance of the antenna switch extension backend. This is the generic backend for manipulating arbitrary GPIO pins. It's just a shell script that the antenna switch extension calls:

I need to get back to this project... has anybody tried any Grove stuff?

WA2ZKD · January 2019

FWICT, the BBG will work with Grove but the kiwi OS version will not... or at least not with the Grove Cookbook stuff

The nice GPIO spreadsheet John had done seems to be lost in the archive here (?)

Not sure what's wrong there. One of my browsers shows the pdf in that thread fine and the other doesn't. Here it is again:

Can you be more specific about what Debian disto you think is required for the Grove stuff? Is it a stock Beagle Debian release or something Seeed has hacked?

WA2ZKD · January 2019

I believe it is off the shelf code, but let me confirm that

WA2ZKD · January 2019

http://wiki.seeedstudio.com/BeagleBone_Green_Wireless/ has detail I need to explorehttp://wiki.seeedstudio.com/BeagleBone_Green_Wireless/

Looks like it works on normal Stretch using the mraa stuff. I have a BBG with jessie on it, I'll change it to stretch and advise

WA2ZKD · January 2019

I have the Grove stuff working.... I just installed the latest debian stretch release. Obviously, as it needs stretch, my work so far has been on a bare BBG, not a kiwi

WA2ZKD · January 2019

further news.... the BBG supports Grove UART and I2C only, not analog and digital. That limits what Grove Module will work with a basic BBG.
