Re: Adafruit Nexopixel Library not working...
for neopixels I've been thinking about using Timers and DMA https://www.thevfdcollective.com/blog/stm32-and-sk6812-rgbw-led https://ralimtek.com/posts/2021/ws2812/ think Adafruit's Neopixel lib uses SPI? well nothing 'wrong about it' but that using Timers possibly 'saves' an SPI port and is possibly...

Re: WeAct Studio STM32F411CEU6 BlackPill v3.1 crystal is 8 MHz
among the things to try, after successfully flashing through st-link, try with DFU again, maybe make some changes so as to tell that that is installed from DFU. it is quite possible the flash could be write protected. But that with st-link, there is a special means connect under reset which can ove...

Re: WeAct Studio STM32F411CEU6 BlackPill v3.1 crystal is 8 MHz
if you can work with fpiSTM to do a commit for a new variant for 8 Mhz (by means of a PR pull request) do help to test that. the files that are needed to be updated are a copy of that variant file with a new name, and maybe some other source files (i'm not sure but you'd need to check), e.g. the inc...

Re: WeAct Studio STM32F411CEU6 BlackPill v3.1 crystal is 8 MHz
if the stm32cube programmer messages make sense, it seem your boards are actually working, otherwise cannot even program. but the blink test not working is unusual. I rebuild a blink test with some other test usb, adc, temperature reading, whetstone benchmark etc my board is 25 mhz, I've rebuild thi...

Re: WeAct Studio STM32F411CEU6 BlackPill v3.1 crystal is 8 MHz
if that doesn't work, then it is unlikely to be a clock issue, because by returning in void SystemClock_Config(), before clock setting.
it is running on its internal clock, not even on the crystal
it seem you have a few boards, all of them don't work?

I also bought the same boards with HSE 25 MHz today, but they will arrive no earlier than in 2 weeks.

Re: WeAct Studio STM32F411CEU6 BlackPill v3.1 crystal is 8 MHz
for 32k RTC crystal , i've a few times it doesn't oscillate, but normally for the HSE 8, 12, 25 mhz crystals etc, seldom have problem, so it is surprising if HSE don't oscillate, but maybe sometimes that can happen.
