#Floalt led panel code

The code that executes a brightness change in practice sets up DMA between a pre-populated fade table in SRAM (source) and the timer responsible for doing PWM to the LED (destination). So when I set it to min 1% I'd just get (approximately) 100, 45, 23, 10, 5, 2, 1.

The first patch region around 0x92xx reduces the minimum brightness, but isn't enough on its own since another aspect of the code still results in 7 brightness levels, fitting some polynomial curve.

Note this is the sum over what flash really contains, not what a firmware update contains (updates don't contain empty bits, and probably do contain some signature overhead).įactory default brightness levels are 100, 60, 35, 21, 13, ~8 and 5 (% of full). This is obviously not proper documentation (just the 'what', not the 'how' and only minimal 'why'), but in case I have a stroke or something, the patch against 1.2.217 is: 0x000092dc 3868401c => 00bf00bfĠx000092e1 eb80006421b0fbf1f0 => bf00bf00bf4ff02000 Raise a bug against the instructions to get my attention if you follow them and find holes in them.Ī superficial look suggests it'll work with minimal adjustments on the larger panel sizes too, but nobody has tried yet to make sure. The wrinkles in this may not yet have been ironed out guidance of the other willing panel owner got stalled by slow delivery of their Blue Pill from China.

A USBserial cable would also come in handy.Įdit 2: A rough walkthrough can be found on Github. If you're nerdy enough to follow along but don't yet have a SWD probe, buy yourself a Blue Pill for two or three dollars on eBay. With that in mind, anyone else want to try this out on other models? If so, I could guide someone through it, or maybe even write it up properly.Įdit: I am now guiding someone through this, and will document it as we go. If all that sounds scary, or like Greek, or like a scary Greek, this isn't for you. It's not for the faint of heart, and probably not worth it unless you find soldering fun I mention it only because several people seem to have asked for it/complained about the lack of it on here, and because maybe one of those is patient/determined/nerdy enough to try.Īmong other things you'd need: a Floalt you wouldn't mind accidentally frying, a healthy fear of mains electricity, a healthy indifference towards warranties, soldering skills, probably Linux and/or embedded skills, and a JTAG or SWD probe. Alternatively, you can control the devices with a TRADFRI remote or using the Ikea Home smart app on your smartphone.I wanted to use the Floalt (30x30) as a sunrise alarm clock, so I hacked it to have 32 levels of brightness (default firmware had 7) starting at 0.05% (default firmware bottoms out at 5%). You can then control the devices with Amazon Alexa, Apple HomeKit or Google Home. You need to have the TRADFRI gateway to use these devices, which may be getting a refresh itself.

The device is said to measure 306 x 131.5mm (~12 x 5-in). According to these sources, the device would be able to charge gadgets connected via USB-C at up to 18 W and wirelessly via the Qi standard at up to 5 W. MobiFlip found FCC and WPC listings for the potential gadget, though they gave few details. Ikea has not confirmed if this is the case.Īnother possible new smart home product is the SYMFONISK Charging Shelf. The current smart devices come in various shapes and sizes, and are dimmable between 2,200 K and 4,000 K.Ĭaschy’s blog, which spotted the change to the product listings, speculated that this could signal that Ikea will launch new versions of these products soon. The Ikea GUNNARP LED ceiling or wall lamp and the FLOALT LED light panel have been marked as ‘Last chance to buy’ in several European countries. Another report claims that the company could also be expanding its SYMFONISK range shortly. A product listing update indicates that Ikea may be updating its GUNNARP and FLOALT lighting ranges. Recent rumors suggest that Ikea could be developing new smart products.
