Re: stm32 vs arduino
stm32 has a huge portfolio of soc for choice you'd only need to take a look at the boards that is 'supported' for stm core https://github.com/stm32duino/Arduino_Core_STM32 - performance tends to be faster due to - clock speeds even stm32f103 is running at 72 mhz - and it is advisable you start with ...

Re: Is the 'EEPROM' library of 'STM32F103CB' safe?
stm32f103cb has 128k flash, stm32f103c8 has 64k flash. EEProm library use that flash that is shared with program codes to store your data. check that storing data will not erase part of your program. note that normally, erasing a full block at the 'back' is 1/2 of the flash so for stm32f103cb it can...

Re: STM32F103CB ‘Sleepy mode’ and ‘Wake up’ function
that is designed for Arduino_Core_STM32 I've not used it prior, hence you would need to review the examples, codes yourself. beyond the library, review the reference manual for your soc https://www.st.com/resource/en/reference_manual/rm0008-stm32f101xx-stm32f102xx-stm32f103xx-stm32f105xx-and-stm32f1...

Re: STM32F103CB ‘Sleepy mode’ and ‘Wake up’ function
library is here https://github.com/stm32duino/STM32LowPower you need to use stm core for that low power is not for novices, to do low power, the simplest way is to consult the reference manual and figure out how to do that from there. in some low power modes, you need to trigger a reset after wake u...

Re: Synthesizer DSP STM32 resources
for synthesizer codes I'd guess it'd take quite a lot of c/c++ codes etc to synthesize https://www.google.com/search?q=software+synthesizer+c%2B%2B if you're keen on midi there are things like gus patches the soundfonts files can easily be like > 100 megs https://www.google.com/search?q=midi+syn+gus...

Re: Synthesizer DSP STM32 resources
Unfortunately, F411 do not have DACs. https://www.st.com/en/microcontrollers-microprocessors/stm32f411ce.html Hence, for this chip PWM is about the only way to do some DAC. stm32g431, stm32f407, stm32f405 etc has DAC, check the specs https://www.st.com/en/microcontrollers-microprocessors/stm32g4x1.h...

Re: Flash and Serial usb f103
if you are using stm32f103c8 blue pill you need to choose generic_boot20_pc13.bin https://github.com/rogerclarkmelbourne/STM32duino-bootloader/blob/master/binaries/generic_boot20_pc13.bin and flash that using st-link (or uart) if you are in windows use stm32cube programmer to flash that boot loader ...

Re: Flash and Serial usb f103
for stm32f103 you need either a st-link v2 https://www.adafruit.com/product/2548 https://www.st.com/en/development-tools/st-link-v2.html https://octopart.com/search?q=st-link+v2 or a usb-uart (3.3v) dongle for a usb-uart you need to set boot0 to program it alternatively, get a stm32f401/f411 (e.g. 4...

Re: Stumbling at the first connection...
for this maple DFU boot loader, after you press reset, it should blink fast for like 6 times, you need to click upload or run dfu-util within about 4-5 seconds when it blinks there is a 'perpetual' mode, and I think the setting is 'boot1' jumper this is from the good old days http://static.leaflabs....
