I am referring to the regulator connected to the usb 5V ( the 5V pin), can it handle a voltage of 12v and step it down to 3.3V for the chip? if not then what is the limit?
Hi there!I have a project with one Master (F765) and three Slaves (F722), connected by different SPI channels for data exchange via DMA. Also slaves use additional Busy and DataReady signals for flow control and synchronization. IRQ handlers works on...
Hi,Months ago I developed a complete project using HAL libraries for the STM32G030K8T microprocessor. Now I need to implement a low power (STOP0) mode and wake-up it from deep sleep using USART. The point is I am facing the following problems:My proj...
Hi everybody,First, I'm sorry for my poor English.I'm using STM32F407VET6 and I want to calculate 16bit CRC of Modbus RTU. Can anybody help me how I can use hardware CRC of the STM32F407? Is it possible to use hardware crc for modbus rtu? Or should I...
Hi,Can someone has STM32F401 discovery board to verify the Accelerometer functionality please?Actually I want to extend the accelerometer functionality for another application.But sadly the accelerometer LSM303DLHC is not working in new application....
I am trying to retrieve data from the onboard ST MEMS gyroscope, but while setting up I2C I have been running into issues. At first I consulted the gyroscope data sheet to find the address associated with it, but both values (0x68 and 0x69) shifted t...
I have tried the HAL without success - It seems to hard fault when initializing RTC.I have privilege disabled, and trust zone disabled,Unable to access any RTC or TAMP registers.Here is a minimal example of code, including the snippets of misc things...
Hi friends, I have STM32L053C8T6TR, where I use PPS pulse from GPS connected to PB8. I set this pin: #define GPS_PPS_Pin LL_GPIO_PIN_8 #define GPS_PPS_GPIO_Port GPIOB void gps_pps_pin_init(void) { LL_EXTI_InitTypeDef EXTI_InitStru...
My connection is below:I have configured STM32F407G as master and STM32F429I as slave from CUBEMX. According to reference manual "The idle state of SCK must correspond to the polarity selected in the SPI_CR1 register (by pulling up SCK if CPOL=1 or p...
