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...
I have done the implementation of 3 wire SPI using DMA and when I do SPI transfer usingHAL_SPI_Transmit_DMA(&SPIx_handle, (uint8_t *)TxBuffer, 8u); the HAL_SPI_GetState(&SPIx_handle) is stuck at HAL_SPI_STATE_BUSY_TX.Not changing the state.My configu...
I'm trying to get the SPI communications to a peripheral handled by the DMA. I have reviewed the STM32L0 reference manual, and LL libraries, as well as close examples. I am able to get Tx operation working properly. However, I cannot get Rx to work. ...
I have found the address of VREFINT_CAL for other processors. THE STM32F205 seems to have the vrefint adc channel on ADC1_IN17 but I can't find the address for the factory cal value.Thanks,Roger KellyROM Communications
