Increase frequency to 480

Hi​Pre-purchased microcontrollers (stm32h743i) can increase this frequency up to 480 MHz?

Accurately measuring board current consumption.

Hi, I'm trying to get as accurate a power measurement as possible on an NUCLEO-F103RB board. I set it up using STM-CUBE to run at 1MHz and all peripherals in the default state. The only code I am running (once initialization is complete) is an empty ...

BlueNRG-2 IIC error with reading more than 16 bytes

Hi, I am working on BlueNRG-2 and I need drive NFC-EERPOM(M24SR64). I tried to read from M24SR64, I got error when the reading bytes were more than 16.(It was ok <= 16 bytes), it stuck on the while loop as below. I put my readfunction and init func...

STM32F4. Interrupt from DMA burst writing only once appears

MCU is STM32F405. I write data array to output pins using DMA mem to peripheral (DM2 stream6 channel0). Trigger is TIM1 CC1 event. Also I use DMA2 stream5 channel6 for write to TIM1 registers. Trigger is TIM1 UEV event. So the writing and interrupt D...

STM32F103C8 I2C module enters to busy state and cannot get out of it

Hello, I am trying to communicate with an SMBus battery. That has 2 sections so I am using 2 I2C modules. There was this problem: After the first I2C module makes a successful communication second module gets stuck. And it gets stuck in Busy. So I ch...

In stm32f407 when i tried to implement SPI communication (data send only) the OVR and RXNE bit is enabled what is the problem? and how to solve that

DAC in DMA not working?

dear all,I keep studing the STM32H7 architecture and this time I am trying to control a DAC using DMA which seems an easy task. However, in my case, the output is always at zero. I have used it without DMA and it works, therefore my HW debugging work...
