Thanks will look into... Might be able to test tomorrow...

Sorry need some reference here....
Is OUTPUT_OPENDRAIN active LOW... with HIGH being floating?

I need to set a pin with open drain but not have a HIGH/pulled up state when not active.

I thought the F0 range was meant to be for low power? Or did I have that wrong?
Yeah the LDO battery chip is going and hopefully we should see some significant improvements there. But I feel we should still be able to reduce the stm32 further than 4mA

Using the built in sleep library "STM32LowPower.h" When going into deep sleep mode, I'm still reading around 4-5mA, from what I've been told we should be able to get this number down into the uA. Is there anything more I can do to reduce this number? I did see https://electronics.stackexch...

Also not working on a bluepill....!

I went with adafruit for this "quick" job thinking it be simple and off the shelf..... So you saying it needs to be tied to a spi out pin?

Even tried swapping the 8mhz crystal with a 16mhz.
And changed
uint32_t SystemCoreClock = 8000000;
to
uint32_t SystemCoreClock = 16000000;
in system_stm32f0xx.c

still having the exact same issue, even adjusting the dividers around to account for the new clock.

Not sure I set the pin correctly as the signal wasnt sharp but only in a few mV variance, but I manged to get 47-50mhz off PA8. So the mcu isnt underclocking. But still only getting 284khz signal for the led string. Im really out of ideas here. its clear the signal is too slow coming out. But I cant...

2 things. Firstly im not convinced my mcu is running full speed. Even though I have this in my generic_clock.c void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; /** Configure LSE Drive...

Hi fpiSTM has said in other threads this lirbary has been forked/ported to stm32core. But im having a real hard time getting it to work. Basically my led strip is only showing white. (full RGB) Whats interesting. if I set the leds less than my strip length, it only lights that number of leds. So som...
