STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello! I just got the STM32F429 Disco board and I'm trying to connect it to the HM-10 bluetooth module. I'm completely out of my depth here, I was hoping someone could nudge me in the right direction.I've worked with the HC-05 and the HM-10 on the ar...
I try process USART 1 upgrade over bluetooth module connected here.App setup all and jump to system memory, but here PA0 change and reset my here connected bluetooth. PA0 isnt defined in AN2606 .
Hi. I am using stm32l01c6tx. I want to use a very simple microsecond function. Libraries I have added below. "DWT" "CTRL" etc. when I included the libraries. It says not defined. But they are all in the "core_cm4.h" library. This library is in Driver...
In application note AN2834 (How to get the best ADC accuracy in STM32 microcontrollers), There is a clear error on Page 10, which defines 1 LSB by Vref+/2^12). But LSB depends on Resolution!If Resolution is 10, then it would be defined by Vref+/2^10....
I am using Nucleo 144 H745ZQi , connected vbat pin directly using coin cell, when power is off/unconnected, LD7 led ovcr indicator turned on and current consumption drawn from baterry was 50mA, also the LD5 led turned on. However when i reconnect the...
I have followed an example found on the web to get DMA RX usart2 running.I had activate RX DMA, global interrupt in cubmx project.In the main I have :HAL_UARTEx_ReceiveToIdle_DMA(&huart2, RxBuf, RxBuf_SIZE); __HAL_DMA_DISABLE_IT(&hdma_usart2_rx, DM...
I am trying to run code in LPSleep mode. I found a video that seems to describe the use of SuspendTick and ResumeTick to do this. I have created a small example where I push a button it jumps into an EXTI handler and toggles an LED. Within this IS...
I have a scope and am triggering on the falling edge of a pushbutton. The LED drive signal is being monitored on another scope channel. The LED is to turn on 50ms after the falling edge of the pushbutton but in reality it is 62ms. LPTIM1 is runnin...
