Re: F405 & F411 versions of the BluePill

Yes. My understanding on all F103 MCU's was the page size didnt change Its something like 1k on the Low Density MCU's and 2k on the medium and possibly 4k on the High density. But all pages in the same MCU will be the same size. Having different sizes at different locations in the flash is a pain, a...

Re: F405 & F411 versions of the BluePill

Victor I had not considered the flash writing part of the code. It’s strange that the flash page size changes depending on where the flash page is. On the F103 the page size is bigger on the devices with more flash, I remember looking into this, but can’t remember whether it was for the bootloader o...

Re: AC Dimmer

Your board looks good. Did you etch it yourself ? BTW. I found it was cheapest to buy a high power dimmer board from eBay, then remove the triac and heat sink. The only problem is that the position of the screws for the heat sink can change, if you order some more dimmers, even if you order from the...

Re: Interesting pull request to add build options

OK

Normally I find I can edit the source in a library, using an external editor (Notepad++) and I don't need to reopen the IDE etc

The only time I need to close and open the IDE is when I make changes to platform.txt or boards.txt

I agree. It is not worth the effort etc to have this for libraries at the moment

Re: AC Dimmer

Not the most compact of boards, but this was my prototype power controller board IMG_20171212_153930.jpg It does not include the BluePill, as that attached via the pin header on the far right The zero crossing detector is along the bottom, the power FET stuff is on the left of the board. There is a ...

Re: F405 & F411 versions of the BluePill

Hi Victor Re: F4 DFU bootloader You managed to get it working more than I did ;-) Re: Using the old bootloader. From the code snippets I've seen, I don't think that too many changes are needed to get the old bootloader to work on the F4 and like you say, its smaller and can use all the existing bina...
