On my f3 discovery board, i was measuring voltage between 5v pin and GND with multi meter and the power LED started blinking . When i removed the the multimeter i noticed the com LED is turned off and the board disappeared from ports in device manage...
I would like to buy a microcontroller package and I am seeing the difference between the Nucleo-64 microcontrollers since they all have almost the same specifications but then I saw that there are 3 notable differences which are "Ultra-Low-Power", "M...
Figure 151, Page 682: The second line in the picture should be "ADC Master EOC".Section 27.5.68, Page 1054: Description for bit 20 ADCTBRST should be similar to bit 14. Currently, it is a circular reference to itself "Refer to ADC3TBRST description."...
Hello there, we're using STM32H743XIH6 MCU for out development.We're at a stage where, we need JTAG to be disabled for Production build and enabled for the Debug build.In order to do that, I searched online, and figured that RDP level can be set to d...
Is there any available example or threads for using multiple SPI slaves on the single SPI bus?
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...
