Project related to creating hardware backpacks for your nodebot to make them more capable.
definitely was working with these specific chips and boards in the past, any thoughts?
I did find a quasi-bug in the keypad backpack firmware though, pin 8 is used for the i2c address and second column: https://github.com/rwaldron/johnny-five/blob/master/firmwares/keypad_3x4_i2c_nano_backpack.ino. You're deprecating that stuff in favor of interchange right?
those are definitely different
Specifically, there is code that allows for setting the I2C address via hardware
You're deprecating that stuff in favor of interchange right?
Uh. I don’t know know anything about that.
Oh, that’s a bug there
The wrong pins are set for A0 and A1
will fix
one sec
@sashasklar fixed.
Would be awesome if there's any backpacks we want to knock over to get them integrated into interchange as well
to make it easy for peeps to install
so you can now do this:
interchange install git+https://github.com/ajfisher/interchange-firmata#depUpdates0.3 -a ... -p ... for example and it will pull the appropriate files from the branch you specify (will use master as per normal if you don't do anything)
by implication that statement means you can also try out latest StandardFirmata from my branch as well as I've now got that built too ;P
That would be ace @gorhgorh - I'm heading to bed now but let me know if there's any issues and I'll knock them over tomorrow. Now Robotnik is in a good place I'm doing a bunch of updates across the interchange related stuff to make sure they are all up to date etc and ready for NBD and will then get onto NodePixel bits
Just updated hc-sr04 firmata code to latest firmata and published that to master on http://github.com/ajfisher/nodebots-hcsr04/ so that can be installed now via direct load. Will publish to NPM soon as I'm upgrading the backpack to handle multiple HC-sr04 sensors on the one backpack as I'm finding this to be quite a common use case. See deets here for comment also: ajfisher/nodebots-hcsr04#5
Hoping to do another release tonight that should install from a local directory if it's available. Just need to figure out the right way to pass it in as a directive to tell interchange what to do. OUtocme will be it will just grab the local bin that's appropriate and jam it onto the arduino
Since this is a robotics centered project I am going to try and ask here. I've been looking for a day now for a program which will stream video and add text. ffmpeg will add the text but I want the text to change. The text will have telemetry data from the sensors on my robot hense it needs to be dynamic. Think of it just like a heads up display. This would seem so common that there should be ready made stuff for it. Does anyone know where to look?
@Legendaire ^^^
What you do is bind your video stream to OpenCV, map a bunch of operations to it (eg transforms, corrections, image detection etc) and then you can draw to the output frame as well and then you can pass that onto a stream for eg serving.
This hasn't seen an update for a little bit (but it's mostly just bindings anyway) but this is usually considered the reference library for Node and is what I use.
I've run it on an RPi1 so Edison should be okay - it really comes down to what is your acceptable frame rate for your application and what operations are you doing to each image and at what size - small image, not much in the way of manipulation or detection and I reckon you're pretty good.
@ajfisher when I flash https://github.com/ajfisher/node-pixel/tree/master/firmware/build/backpack directly from arduino IDE, it is successful, but when I flash using the nodebots-interchange, it runs into error:Sending 3020: receiveData timeout after 400ms.
