Another comparison video on YouTube

Guys, I noticed this new video on YouTube for beginners which compares Arduino on the Blue Pill to an Arduino Nano. He did a good job, but didn't seem to use the bootloader. EaZuKRSvwdo Note. The author has 700k subscribers ! Edit. One other thing I keep noticing is that the LeafLabs docs get used a...

Lecture on firmware patching STM32 binaries

Guys, I thought some of your may be interested in this video I came across on YouTube, which describes methods to patching existing STM32 firmware to add new features and fix bugs in the manufacturers original code GX8-K4TssjY The first 3 minutes can be skipped as it covers an overview of the STM32 ...

404 error on the joining link for me.
I recall there being a problem with the link that victor originally posted. But I can't remember what I had to change in the link to make it work :-(

@cesco

If you have a display connected .e.g ILI9341 you can use it as frame store, albeit reading the data out not that fast

Re: Any ideas what creates a .sgl firmware file ?

Guys, Thanks for your help,but I think trying to decode the firmware update file is impossible / impractical, and there are probably better ways to get at the firmware. I found a post on Hackaday, where someone had managed to extract the firmware from another radio by the same company, by exploiting...

Hi Victor, I'm a bit out of the loop at the moment as I've had other more important things that I need to do (repair my house!) Perhaps if some other people register with AllPCB via your link, then you'd get some more credit ?? I dont seem to be getting spammed by AllPCB, so I don't think its very h...

Re: Any ideas what creates a .sgl firmware file ?

Andy Yes. The radio is a Radioddity GD-77. Well I've already figured out that its actually a Tytera MD-760 but that Tytera (as there are tell-tail signs of the product code in the data files, and Tytera are selling this radio under the Radioddity brand name with the GD-77 model number. It would be n...

Any ideas what creates a .sgl firmware file ?

Hi have a firmware file for a digital radio, which has the .sgl extension, and I'm trying to work out what created it. The file is being uploaded using STM's DFU DLL's, so I initially thought the processor in the radio was a STM32 However someone sent me some photos of the inside of the radio and it...

Re: nrf24 / esp8266 /xbee section ?

LOL... Believe it or not, my 2 year old hot water service ( boiler) contains no electronics at all. It just gas a gas pipe to it, and uses a pilot light lit during installation via a mechanical piezo system ( hand operated push button). And has a mechanical thermostat, which I think is a bi-metal st...
