I've read the Release Notes and they say nothing about any bugs that may have been fixed going from STemwin 5.40 to 5.44 (for example the memory leak in GUI_GIF_DrawEx).Does such a document exist, if so can someone post a link to it please?Cheers

A year ago I had a lot of grief getting the JPEG peripheral working - came down to memory regions! Now I want to improve the quality by changing from JPEG_420_SUBSAMPLING to JPEG_444_SUBSAMPLING but I get random hard faults .Is it possible the jpeg ...

If I try to encode blocks of colour using the hardware JPEG encode in an F7 from a BMP image (screen memory in this case) they fail if the colour is pure (e.g. all red, all blue) and they come out different shades of green.By experiment, I have found...

I've tried both Eclipse and the VSCode Cortex debug plugin to set a conditional watchpoint but both fail (break every access irrespective of value). This I guess is due to OpenOCD not supporting the multiple compare registers in the DWT that are requ...

I'm using a spbtle-rf to scan for BLE beacons. I get the LocalName of the device scanned and its hardware 'MAC' address using either aci_gap_start_limited_discovery_proc() or aci_gap_start_general_discovery_proc() but I can't find a way of reading th...

Check that the memory you use for the DMA buffers is accessible to the JPG block. I had 6 months of grief finding this out on an F7 as by default only the first 128k is in the correct cache region

Rather than 'Blue Pill', take a look at 'Black Pill' which has a choice of f401 or f411. Make sure to get the latest V3 PCBs, there are a lot of sellers flogging off older versions.BTW: The last Blue Pills I got had fake f103 on them - took a lot of ...

I (eventually) received panel initialisation details from the LCD manufacturer. They were quite a lot different to what I'd started with from online trawling and after that everything just worked (apart from a couple of tweaks to the PCB layout on th...

We have also found the PDF describing using BTLE for social distancing, it's the code that implements it that we're after as well.My investigation has succeeded in generating beacons with the data I require using aci_gap_set_discoverable() but my use...

On further investigation it appears to be older IOC files that confuse CubeMX. Starting a project from scratch I have no issues but some projects originally generated 2 years ago have all these problems.
