I am implementing a data save procedure when power fail is detected and want to shut down as much stuff as possible to give myself the most time to copy some data into FLASH.Shutting down the CPU has many modes which are quite complicated. I have bee...
Hi everybody! Could please someone enlighten me on the data output format of the ADC1, on regular channels without oversampling, everything is set to default values? Just enabled one channel and converted it. The thing is, I use 2.5v internal referen...
I'm looking for chip for my project. I don't understand about code of STM32L496ZGTx, what is the difference.
Hi,I'm having some issues regarding removing and reinserting an SD card on the STM32H722 using the provided HAL. I'm not doing anything special (no DMA, no interrupt). Just using the provided SDMMC1 and FATFS. First, I noticed that the library won't ...
When using HAL_UART_Transmit you normally give a timeout.If Transmission time exceeds Timeout the function exits with HAL_TIMEOUT.There're two issues with this approach:1) Timeout should be retriggerable i.e. if I transmit 20 bytes @ 9600Baud an put ...
I try to use "arm_math.h", but I can't find any function about logarithmic operation in "arm_math.h". Is there none logarithmic in this, or am I not found?
I have implemented the following CAN Codeint main(void){ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* Configure the syst...
Hi, experts May you have a nice day! Recently, I am learning RM of STM32G474. I am a little confused about the bulb sampling function. It seems that this function cannot shorten the ADC sampling time, so what is the use of this function? hoping anyon...
I need a clarification about something that I read in RM0351Reference manualSTM32L47xxx, STM32L48xxx, STM32L49xxx and STM32L4Axxxadvanced Arm®-based 32-bit MCUsRM0351 Rev 9...During and just after reset, the alternate functions are not active and mos...
Hi, I did never ask in this forum but used STM32 MCUs for years. Allways I use 48+ pin parts and all work like a charm. I'm very happy with the family and did stop to use other Cortex brands years ago. In 2019 I did work in a project that did involve...
