Yes it could be faster but it is programming 308K! As usual with flash it is the erase time that slows things down. I tried loading the same data with J-Link and it took around 7s. The original micropython makefile uses a python script which took 22s. Using gdb and a BMP clone took almost 18s. So I ...
By coincidence I had downloaded this on Tuesday because I had hoped it included an SWO viewer that I could use under Linux -- sadly it doesn't appear to. It works fine with OpenJDK on my Fedora 27 laptop using OpenJDK. The only catch was needing to install openjfx -- otherwise you get cryptic errors...

The R in STM32F446RE board name indicates it is a 64 pin part. If you check the STM32F446 documentation you will see that only PD2 is available on any output pin -- so your configuration of PD12 is in vain. I assume you are another victim of the ambiguous Arduino pin numbering and that you are using...

Unfortunately, it seems to show that open source code will be inherently less secure as reference code can be run, and the power usage compared. Roger, I think you are being too pessimistic! That argument smacks too much of Security Through Obscurity to me. I believe some of the most secure impleme...

I think the udev rules provided in the core are not ideal -- certainly not on a systemd based Linux system. On my Fedora and Arch systems I didn't have a plugdev group and didn't have full success when I added one. Essentially, I still needed to use sudo for the dfu-util command. The solution I have...

I've been lurking on the forum since April and have finally registered. I'm another one of those old fogeys that seem to be here: originally cutting my teeth on the National Semiconductor SC/MP II micro -- not even a jump subroutine opcode -- through the 6502 (PET/BBC Micro) and various TI/Motorola ...
