Resolved! STM32H7BI3-DK WiFi Not Working
Hi,I have been writing drivers for the ISM43341-M4G-L44-SPI WiFi module mounted on the STM32H7BI3-DK.I can send the device AT commands and get back the OK response, but after setting the network parameters SSID, password, security mode, DHCP after is...
Are there a STMF4 or STMF7 ADC overun detection code example?
Hi,I´m working with a STMF767zi and STMF429zi kits and I´d like detect ADC overrun. Sow I write the callbackup code:void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { flagOverRunCH1=0; if (hadc->Instance==hadc1.Instance){ // Overun detection/* ...
Synchronize Timers of 2 different Stm32f767zi nucleo Board
Hi everyone,I have synchronized the clock of 2 F7 nucleo boards with the same external oscillator. To do that I have activated MCO of a third nucleo board and then I have connected it to the Pin 29 of CN11 of 2 boards.2 Clocks of MCUs:I have used the...
STM32F429 Disco with HM-10
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...

There is no DWT in the M0/M0+ kernel.
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...
Resolved! Error on Application note (AN2834), AND Where to report it?
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....
Vbat pin drawn high currebt when power is off
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...
DMA Uart Rx occur only once
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...
