Hello everyone :D I am currently using the STM32H743VIT6 (LQFP-100) on a custom PCB.My goal is to generate fast positive pulses (ideal case would be a 10ns pulse) on TIM4 CH2 (PB8). APB2 is clocked at 200MHz so I can get 5ns ticks from my timer.Gener...
Hi!!! I am using STM32H743BIT6 MCU and I want to measure the speed of reading a binary file (image) in SDCARD.SDMMC1 is set and SD 4 wire bus is set.On which pin should I take the measurement on the MCU? Also, the unit of speed is (Mbyte/s). Is it...
Making a port from F334 to G474 controller, used CubeMx 5.3 to do 1 PWM using HRTIM CHA 50% duty as a test and got a this error during compile.
Hi, i converting/translating an arduino code to STM32. Do someone know a similar function in STM32 Cube as arduino "serial.write" and "serial.print"? I know that the function "HAL_UART_Transmit(&huart,Data, size, 100)" works simalarly as serial.write...
I am using STM32H743Bit6.Checking GPIO maximum frequency.Among them, in output mode 11, the maximum frequency of 220Mhz was confirmed in the third environment.What does the 'c' in conditions mean where?
i am able only send 3 frame but i want send 5frame ,what i am doing wrong ? if (HAL_FDCAN_Init(&hfdcan2) != HAL_OK) {Error_Handler();} FDCAN_FilterTypeDef sFilterConfig; sFilterConfig.IdType = FDCAN_STANDARD_ID; sFilterConfig.FilterIndex = 0; sFil...
I am using STM32H743Bit6.#define GPIO_SPEED_FREQ_LOW (0x00000000U) /*!< Low speed */#define GPIO_SPEED_FREQ_MEDIUM (0x00000001U) /*!< Medium speed */#define GPIO_SPEED_FREQ_HIGH (0x00000002U) /*!< Fast speed */#define GPIO_SPEED_FREQ_VER...
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 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 ...
