STM32 neural network in_data had concated my raw data, but out_data always show 0...
I had check program for erros or not and try to adjust possible parameters ,it's still unworked for out_data @@. Are some ideas, guys?

I am using STM32L471 controller, I just want to ask that what is the maximum value of decoupling capacitor which can be used at JTAG SWDIO pin of controller, so that there would not be any issue during programing of controller using SWD 4MHz setting.

Resolved! User byte address in option byte (store 2 byte except flash memeory)
Hello All,I am using stm32g030f6 mcu.I have done this project before with stm32f0 mcu and now i am porting it to stm32g0 mcu.flash size of each is 32kB.The project is filling up all the processor's memory.So I used option bytes to keep some values in...
Ping pong buffers in speech IO
Hi,I am trying to implement a speech IO system using stm32f4 discovery board. For this I am using interrupt for extracting(from digital mic) pcm samples to a buffer & for output(using polling) I am continously writing circularly the same buffer con...

STM32 Nucleo boards - how to calculate xtal load capacitors
I'm aiming to add an 8MHz xtal to a Nucleo-L496 board but I'm struggling a bit. The recommended part isn't available, I've found one that will fit but the load capacitance is 10pF compared to 8pF of the one in the manual.However, what is confusing me...
Resolved! Iam using stm32F4 discovery board to find FFT. But when i use the arm CMSIS library i am getting errors like this

Resolved! Debug mode cannot be invoked
Since I flashed the Nucleo-F439ZI board with a firmware, I can neither flash another firmware nor go into debug mode. No error message appears in the console. What could this be?
