Re: F405 & F411 versions of the BluePill

Squonk if the design in Eagle is all good, do you want to share the Gerbers to order some PCBs? or you expect some changes in the redesign with Kicad?

Re: F405 & F411 versions of the BluePill

Not 100% certain, but I think in the F1s the page size is the same size for all pages in the same device, but look at this with the F4, 3 different page sizes! in he same device:

Re: F405 & F411 versions of the BluePill

I think the register addresses for the GPIO are different (and also for the USB controls), and I know the GPIO clock settings etc will be different. But the GPIO stuff should be easy to crib from the LibMaple F4 core. I believe you are right about GPIO, just the base addresses are different, but sa...

Re: F405 & F411 versions of the BluePill

Yesterday I saw an old video from STM on the right way to jump to the rom bootloader: https://www.youtube.com/watch?v=cvKC-4tCRgw Seems to be straightforward, have not tested it thought, but should be easy to test. I'll try when I get a second. @Roger you are giving me too much credit, I barely modi...

Re: AC Dimmer

Victor I looked at the data sheet for the moc3043 but the Zero crossing part if the chip something to do with only turning on the triac at zero crossing and not part of the detection as far as I can see I think it’s for a different use, where you have a highly inductive load and don’t want to turn ...

Re: AC Dimmer

MOC3043 for example has zero cross, is the same as MOC3023 + Zero cross. Pito may have misstyped 6/8 @Pokemon: This is my zero crossging ISR: https://github.com/victorpv/reflowOvenController/blob/master/bluePillReflow/bluePillReflow.ino#L155 But as you see here, I am simulating it with a timer to us...

Re: AC Dimmer

I wanted to know if there was an opportunity, run on two timers, that's all. You can, the switching won't be synchronized with the AC wave, so no good for lighting, but for a heater you should be ok. I do something similar for my reflow oven controller, and works fine, though I plan to enable zeroc...

Re: AC Dimmer

Andy are you suggesting the capacitive dropper+ the opto? The opto provides isolation, so the schematic from pokemon has isolation. About using it without cross detection, you could modulate power by turning on for a number of cycles, then off for a number of cycles, rather than for a percentage of ...

Re: F405 & F411 versions of the BluePill

I have not used the hardware dfu in the F4, normally just use the STLink. That said, I see we have two options: add extra components to pull those pins low, which may affect their usage for other functions (if the pull down is too weak, it may not have an an effect other than if the pins are floatin...

Re: F405 & F411 versions of the BluePill

Roger, it's the same for me with dragging, tracks only in openGL.
I haven't tried dragging a component in canvas mode, need to try that, but in OpenGL dragging a component doesn't drag the tracks attached to for me.
So openGL mode is the same for me as you describe.
