Anti tampering with STM32L4

I'm working on a project with an STM32L4 microcontroller and I need to implement an anti-tampering function to detect if the case has been opened using a switch. I know that the STM32L4 has an anti-tampering function on pin PA0, but I'm already using...

I have a LUT and need to read from non violatile flash. but dont know how to save it before each power cycle. the size is very small 3k. could i put this in a h file and load in cubeide? what path shall i use if using txt? any example?

I do have time working but it will reset each time when I power it off. I do have the backup battery connected.I thought that it is supposed to keep working on battery and I guess it does. But I guess I might be missing a few lines to read registers ...

UART DMA Rx/Tx

I am working on STM32F401RE, transmitting data via UART using DMA 1(channel 6) , also i want to receive data using DMA 1 (channel 5). I want to use the DMA in single byte transfers in direct mode. Can you help me how to do so correctly because i trie...

Hello, I have a STM32core F446RE board that I should clone. I need to download the configuration that it has loaded to be able to take it to another board. How could I do it? Thank you very much in advance. Greetings.

STM32G4 series fastest way to add 32 16bit signed integers

I have the following function to sum 32 16bit signed integers as optimally as I think is possible:int16_t sum32elements2(int16_t vals[]) { uint32_t s1 = __SADD16(*(uint32_t*)&vals[0], *(uint32_t*)&vals[2]); uint32_t s2 = __SADD16(*(uint32_t*)&val...

Update ARR value when timer is enable ?

I want to update ARR new value when timer eneble(counter is counting). What can I do to update it quickly without time latency (like setting the UG bit) ? I am using stm32f0.
