Arduino for STM32

Hi everyone
I decided to make a voice recorder.
I know that I need a 44.1 kHz sample rate to cover the entire range of human hearing.
stm32f103 has 5MSPS ADC, can I use this?



Google this: stm32 + voice site=github.com

Thank you so much :)

Thanks for your reply

Hi
I have problem with stm32.
Nothing show on OLED

How I can put stm32f103 to sleep mode in Arduino IDE?

Hi
Is there any way except restart micro controller, to go back to setup() when we are in loop() ?

I'm using STM32F103C8T6 with my own designed PCB, using 8MHz for main core and 32.768Khz for RTC and 3v 2032 battery.
Yes LSE is enabled, I attached the code above.

Have you changed clock source to external ??

setClockSource(STM32RTC::LSE_CLOCK)



when I change clock source, the program stop after change.

This sketch shows how to configure the RTC and to display
the date and time periodically

Hi
I'm using STM32RTC lib to get time, but when the board reset time reset too, I know I should work with RTC backup register, but how on Arduino IDE?
