Re: UT61E SD BLE logger

keeping an eye on this, also bought a UT61E for its logging capabilities :) Maybe also worth mentioning here: when mine arrived a few segments on its display were hardly visible (luckily this meant there was a signal & they weren't broken). A bit of googling showed me some videos on how to clean the...

Re: F405 & F411 versions of the BluePill

I started with the F103 for 2 reasons: -The F103 has mature code with plenty of libraries, sketches etc, and I know how everything works better than the F4. -The MCU is half the price, so if I burn 1 it won't hurt as much. So far I tested the button with a 2k resistor, and works just fine. I believ...

Re: F405 & F411 versions of the BluePill

Is there any list of mcus which fit onto the board (without any mods)? we should make a list, but when discussed earlier, i think the conclusion was that almost all 64 pin mcu's are compatible (with the only differences being the 103's requiring a 0R resistor where the others require the VCAP 2.2uF...

Haha, I was joking!

Do you have a known-working STM32F4xx board (STM32F4DISCOVERY)?
maybe, not sure, i'll have a look in my big drawer of boards XD
*edit*
found a 407 board, should be close enough i hope :)

Ideas: reverse the LeD :)
thanks for the vote of confidence :p

already checked all electrical things, it's not that, probably just something going wrong with the program i generated via cubemx

Re: F405 & F411 versions of the BluePill

i'm indeed running on HSI @16mhz atm, just the very basics
but i'll see if i can do some SWD debugging to see if i can find a reason it's not starting the blink program >_<

Re: F405 & F411 versions of the BluePill

i've been trying to get a basic blink program running, but for some reason it's not working >_<
i can program the stm32, but can't get the blink working, wondering if i made some stupid mistake >_< (i hope i didn't damage the mcu)

Dual soldering iron :?
ow, just saw it's just the caps that are switched, shouldn't be hard to fix with my hot air station :)
*edit* swapped them ^^
really glad i have a hot air station, a cheap aoyue one already goes a long way when working on such pcb's :)
