Bonescript shiftOut() question

Is Bonescript shiftOut() supported? and with what version?

I am running the 3.8.13-bone47 #1 SMP Fri Apr 11 build on my BeagleBone Black and I was using spidev_test.c to test talking to SPI devices. And my board says: running BoneScript 0.2.4

Well my coworker was wondering if we could do SPI with Bonescript instead (Performance not really a goal today).

When I looked into this BeagleBoard.org says:
shiftOut(dataPin, clockPin, bitOrder, val, [callback])

Note: This doesn’t work until BoneScript version 0.2.3

http://beagleboard.org/Support/BoneScript/shiftOut/

But when I click on the shiftOut example on my BBB it says:

Cannot GET /Support/BoneScript/shiftOut/



Is SPI supported from Bonescript and which version?

Thanks!

I will just copy the example on beagleboard.org, or just use beagleboard.org to connect to my BBB (just realized you had an option for that, pretty dam cool!). I tried this briefly and was not getting any output on SPI0 but I’ll take a look with a logic analyzer tomorrow to see exactly what is coming off the pins. And in the meantime we will use spidev_test.c to write to SPI but still would like to get this working from within node.js!

Did you know? This page can interact with your BeagleBone

So cool…

Jesse, you should still be able to use Nodejs if you can present the SPI to the system as a filesystem object. There is always mmap too, but more complex . . .

The example documentation and the implementation of shiftOut are
separate. shiftOut works fine in 0.2.4.

Not directly yet.
