Hi,I'm using the STM32L4R5AG MCU with 4MHz MSI clock.I want to use I2C in fast mode (400kHz).The PCLK for I2C is also 4MHz from the MSI directly (in my application, I don't want to use a PLL).In CubeMX for 4MHz PCLK, if I select fast mode, the TIMING...
I have a Pi that sends data to the MCU via SPI. I have the SPI running in DMA circular buffer mode on the MCU. In the TxRx callback, the data from the Pi is processed, and then the motors are turned ON/OFF, etc. This works, however, each time the Pi ...
I am working with the STM32F769 microcontroller (SystemCoreClock: 216 MHz) and I need to generate a roughly 3 ms pulse (negative pulse is also ok), that is always exactly the same, on pin PG14 for calibration purposes. According to STM32CubeMX, the p...
Hello, i am building the clock setting based on HSE in STM32FG14 using the link bellow.1.At first i am setting the 16th bit of the CR register of RCC and wating till 17th bit will be ready2.enabling power3.voltage regulator setting4.FLASH ACR setting...
Hello,I am reading data from a motion sensor but I would like to save processor resources as much as possible. I want to implement I2C with DMA support.Presently I have external interrupt (EXTI) from sensor which signalize that data in FIFO are ready...
Hello, I've managed to compile, debug and flash the code from homework onto the device (using Cube ver. 1.6) and was able to run the CubeMonitor under linux Manjaro. Everything works just fine and according to the slides, except that myProbe_Out and ...
This is a fairly high-level question... but just wondering whether the NVIC system is capable of interrupting an interrupt when one of higher priority comes in? Can someone point me to information on this?Thanks,Doug Burrell
Hi everyone, I am currently working on a project working on a STM32F469I-DISCO. I would like to be able to use the embedded RTC as well as the backup SRAM. I have seen on the schematic that the VBAT pin is tied up to the 3.3V. Is there a way to still...
