Implement ftdi led device #1595

nurikk · 2023-03-25T19:41:48Z

Hello! This PR introduces ftdilib1 led device implementation. FTDI chips are common usb2serial/spi/whatever chips, and are available for 5-10$ from Chinese website as various breakout boards.

(This is the back port from awawa-dev/HyperHDR#521)

My wiring is following:

FTDI  |  APA102 
AD0 -> CLOCK
AD1 -> DATA

AD3 -> CS (active low) // can be used to drive logic shifter OE pins


FTDI  |  WS2812 or SK6812
AD1 -> DATA

AD3 -> CS (active low) // can be used to drive logic shifter OE pins

I've tested my code on MacOS and webos7(lg tv c2), no extra drivers required.

This implementation is tested against APA102, WS1218 and SK6812.

Requires libftdi1 dependency hyperion-project/hyperion.docker-ci#6

Test webOS builds available here https://github.com/nurikk/hyperion.ng-webos-loader/actions/runs/4520870590

Hi @nurikk
many thanks for your contribution!

Thanks for the PR backporting FTDI support from HyperHDR.
In some areas hyperion works a bit differently.
Therefore, please find some review comments below and related to the files.
I am happy to support you in getting it aligned.

Following additional comments:

The content_leds.js code does not support the discovery mechanism.
Ping me privately on discord and I share a updated version with you or provide access to your repository and I push a commit with some updates...
Would you mind adding libftdi1-dev to doc/development/CompileHowto.md
I am still wondering, if it would make sense changing the backend code that way, that e.g. apa102 can work via SPI or FTDI.
i.e. having common LED type code but working via a different way of communication.
Currently, the e.g. APA SPI and APA FTDI is not consistent any longer.

Hi @Lord-Grey, thanks for a great review! I've addressed all questions.

I am still wondering, if it would make sense changing the backend code that way, that e.g. apa102 can work via SPI or FTDI.

I'd love to do that, but I'm afraid I'm not competent enough in cpp and overall project structure to start such refactoring.

@Lord-Grey can you help me with linker issues? It compiled right for mac os, but it fails on linux https://github.com/nurikk/hyperion.ng/actions/runs/4526347559/jobs/7971453468

Lord-Grey

Thanks for turning the previous feedback round quickly!

@Lord-Grey can you help me with linker issues? It compiled right for mac os, but it fails on linux https://github.com/nurikk/hyperion.ng/actions/runs/4526347559/jobs/7971453468

Please see some feedback below. It should address to issue.

You can also run unix docker compiles with local codes to test before running the docker on Git
For the failing Stretch build you would execute in the local code directory:

sudo ./bin/scripts/docker-compile.sh -i x86_64 -t stretch -b Debug -p false -l

Look at the script and you can easily cross-compile for testing on other platforms too.

Ist the baud rate totally dynamic or does it follow the USB serial baud rates?
If it follows the baud rate, I suggest you use a rateList as in
https://github.com/hyperion-project/hyperion.ng/blob/master/libsrc/leddevice/schemas/schema-adalight.json
to avoid user misconfiguration.

it's not abut serial baud rate, since sk6812 is pwm driven and we simulate pwm signal using spi, allowing users to manually adjust baud rate will help to fix any troubles with dodgy strings. same for ws2812

I am not a Cpp-Pro and would need to investigate about it. There are different options, but not limited to, like a bridging class, multiple inheritance, using templates, etc…

I really liked the previously white calc. algorithms ("auto", "auto_max", "auto_accurate"), could we have them back (or they get removed not intentionally) ?

Is it possible that very low led color causes the led flashing between on/off? I used the same length cable /5cm?/ + level shifter /sn74ahct/ (even hooked OE to GND instead of CS /AD3/) as used for esp32 where this problem doesn't occurs. I captured short footage of the issue (the movie was paused):
https://youtube.com/shorts/y1rV8DnI5q0
https://youtube.com/shorts/yPuYVCJ0Oe0
It's totally (source) content related, i couldn't reproduce with effects/colors, also have some 'random' (occurs around some white 'area') white flashes.

Any idea what can cause this? I tried different baud rates, latch time, slower led update rate, but the problem persist :/.
I don't think the problem is related to my hw (everything is kinda the same as I mentioned above) and switching (on the fly -- just changing the controller type) to esp32 + hyperserial fixes the issue.

p.s.: SK6812 RGBW strip

satgit62 · 2023-04-26T08:02:43Z

@asturel
I have connected the FTDI without level shifter and I do not have this error. I also use SK6812RGBW.

asturel · 2023-04-28T23:06:17Z

Is the reset time typo or lowered on purpose based on some tests? const int SPI_FRAME_END_LATCH_BYTES = 3; https://github.com/nurikk/hyperion.ng/blob/ftdi/libsrc/leddevice/dev_spi/LedDeviceSk6812SPI.cpp#L45
According to SK6812's datasheet https://cdn-shop.adafruit.com/product-files/2757/p2757_SK6812RGBW_REV01.pdf the reset time is 80µs, so with 3000000 baud rate it should be 30 (?). I have bumped to 32 at first (calculated with 3200000 baud) and seems like the issue is gone, but from a short test i haven't run into issues with 5 either.

btw it shouldn't be dependent on leds count? (the datasheet applies to 300 leds (?))

m4rkusxxl · 2023-08-28T17:09:11Z

I use a FT232H without a level shifter and tried this patch, but I had to do some adjustments:

Mixture of ENABLE_DEV_FTDI / ENABLE_FTDIDEV
After opening the device I had to add a 1s sleep for it to work.
Not sure why, but ftdi_usb_get_strings failed hard. I removed it but thats of course not a good solution ;)
As I applied it to the current master, I needed to adapt the deviceList keys to systemLocation and deviceName.

With that being said, its driving my old 189 APA102 setup without any problems for two weeks now.
So thank you for the work and looking forward to get it merged.
