I have tried using the HAL_I2C_Master_Transmit_DMA and HAL_I2C_Master_Receive_DMA functions to access an external I2C slave but I find that this takes a fair amount of processing time. I am using a STM32L476R M4 core device. Using a GPIO I measure th...
Hi,I have some troubles with my Nucleo STM32F446RE communicating with my MPU6050 IMU over I2C. When powering everything the first time and debug it, it works fine. However, when restarting with exactly the same code, the board fails to start the I2C...
Hello,We are designing automotive devices (Trackets,Meters etc) and almost in all of our devices we use external watchdog with integrated BOD function.We faced issues in the past during EMC/ESD tests, where the microcontroller's (AVR) BOD or watchdog...
At evening I set time 18-38-00, got it back, it was OK and left it to run. At morning I see the time 32-59-48. My set-get functionsint RTC_SetTime(uint8_t hours, uint8_t minutes, uint8_t seconds) { if (hours < 24 && minutes < 60 && seconds < ...
bit time = [NTSEG1 + NTSEG2 + 3] tqAnd in the note With a CAN kernel clock of 48 MHz, the reset value of 0x06000A03 configures the FDCANfor a bit rate of 171 kbit/s.NSJW = 6NBRP = 0 => 1NTSEG1 = 10NTSEG2 = 3How do you get 171 kbit/s by 48 MHzBest Reg...
Hi I am currently developing a radar backend system wherein I need to pass ADC sampled data at 2.6 MSPS to PC for post processing. I am stuck to which communication type will be optimal for transmiting such data from STM32H743ZI to PC.
Here definition from the datasheet, but in the 32pin package there is no VDDA !Is any VSS also the VSSA ?
When working with STM32CUBEMX. After I clik to Generate Code, and want to open the project I get the message>"Install SW4STM32 Toolchain to open the project.Thank you for you help!
Hi everyone,why they mentioned (64Mbit accessible only) in QSPI?
Hai, We are planning to develop a custom board with STM32F413ZH and STM32F413VHT6 so we are looking for a ST BLE module to be interfaced with these controllers.So can anyone suggest me which is the correct one and good feasibility of BLE stack util...
