short on VBAT?

recently i tried to meddle with RTC on my Baite MM clone, RTC 'simply works' thanks much for the really good effort here. then i hooked up a CR3032 coin cell on VBAT pin on the MM, it seemed to run quite well initially keeping the clock going after removing USB power. after less than a month the CR3...

Re: BluePill on Hackaday again

actually i think hackaday should feature our 3 different arduino cores libmaple, stm32generic and stm's very own stm32duino core
it is probably one platform with concurrent 3 different cores that you can choose
:lol:

Re: Graphing calculator feat. STM32F412VGT6

our stm32duino calculator does a different feat, it isn't quite that beautiful but maybe it is possible to draw an fft chart on an ili9341 what our stm32duino calculator excel at is that it can crunch floating point numbers at 500 mflops - no other beautiful stm32 f4 calculators may come close, but ...

Re: Change "Button" pin in bootloader

imho, one of those issues is that it isn't possible to tell what board it is running on, e.g. between BP, MM etc there really isn't anything a sketch or bootloader etc could tell if it is running on BP or MM, that would mean distributing binaries / images and the board or features is in the file nam...

Re: Anyone tried to make a 3D Printer controller?

+1 :) have been caught up with 'real life' recently, having no time to play with these things. But 1 of those things i'd like to do is to pair up one of those stm32f407 boards (e.g. stm32f407 black) with a RAMPS or RAMPS-FD board and have Marlin running on it. it'd probably seem like an overkill giv...

Re: [POLL (Open)]- favorite STM32F1 board for stm32duino 08/2107

oh btw i've got this board https://www.olimex.com/Products/Duino/STM32/OLIMEXINO-STM32/open-source-hardware it is a STM32F103 RB the price tag would certainly look bigger than aliexpress/ebay BP/MM but for its price, some of the features actually looked pretty good, with things like separate LDO reg...

Re: [HackaDay] Take the Blue Pill and go Forth

i'm yet to try out forth too :P the idea of running forth on blue pill or maple mini is an attractive one indeed, https://github.com/jeelabs/mecrisp-stellaris some of those things that's also pretty much using those 'reverse polish' notations are the 'plain old' *postscript* https://en.wikipedia.org...

Re: STM32F407VET6 has 1MB flash !

the other speculation may be that batch of chips that do not pass the qa for 1m are marked as ve, and that those flash are intended to be 'disabled' perhaps as part of the manufacturing process, but that in any case it is decided 'not to waste time' and just mark that vet instead of vgt, so that tho...

Re: [Solved] Brand new Blue Pill does not appear as USB device

i simply used better usb cables, i used one that's shielded with braided wires i once encountered a situation where sketch install always fail with errors, usb detection is inconsistent, that's solved once the better usb cable is used. every install works with no errors no matter how many times i di...
