STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Can I use STM32F411RE to learn DSP programming? Please advise!
I use CMSIS to write program that transfer data from SD card through SDIO. For my task i need 4bit mode, but it isn't working. When i try to read some block from SD card STBITERR bit in SDIO_STA register goes high, that means that start bit hasn't be...
There is a problem with the start-up of both HF (25MHz) and RTC(32k) oscillators after a turn-OFF followed by immediate turn-ON (cca couple ms).Oscillators:EPSON FA-238 EPSON FA-135The RTC crystal does not start-up at all and the HF one does show ins...
Hello,I am using an STM32H753 mcu and I working on a project with 8 GPIO Interrupt Pins. I am using RTX RTOS. The problem is that when the interrupt happens the same time with a thread activation. The mcu goes in dummy handler with bus Precision erro...
This is my test program：uint8_t dev_test=0x00;while(1){HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PIN_RESET);HAL_SPI_Transmit(&hspi1,&dev_test,1,10);HAL_SPI_Receive(&hspi1,test_R,4,10);HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PI...
Hello,I am writing & erasing flash during operation, and this seems to cause a bus stall which prohibits all execution from flash during these operations.AN4808 seems to indicate that if you use a dual-bank device you can avoid this by executing out ...
Hello Experts I am beginner in STM32 , I have a old Discovery STM32 board , I want do some project, Now I require some already availabe libraires ,I dont know where can i get it ?Help me to findout ?
The STM32F070RBT has Hardware Flow Control for RS485, with DEAT, DEDT and DEM bits in USART_CR1 and USART_CR3 registers.How do we identify which series of ICs have these features easily? Is it a particular series or type? The STM32F4 IC we are curren...
That's how it looks: Started the TIM4 interrupt mode:/* USER CODE BEGIN 2 */ HAL_TIM_Base_Start_IT(&htim4); /* USER CODE END 2 */The counter values should be incremented in the middle and in the end of the period, however it doesn't happen. There...
