HelloMy app does not start without the debug probe.I replaced source code (app with freertos) by a simple blinking led, and it starts withoutthe debug probe (segger j-trace)...Any idea?Edit; Moving around a blinking led in the code, it appears that c...
I am testing the stemwin using the stm32f429i-disco Board.When building the project, I get the following error and I can not trace the error.This error occur when i use GUI_Init() FunctionPlease help me!!
I would like to sample 3 channels simultaneously and continuously.The plan is to use the ADC in continuous operation and DMA.Is it possible to have all 3 ADC sample at the same time?And if so, how can this be achieved?
Hello.I do not find in the datasheet (for example STM32F072) information that will allow me to conclude what the maximum clock frequency the timer (for example TIM1) hardware (via ETR) can support.Can you help me?I have knowledge of similar experienc...
Hi,I am trying to use all the 4 PGAs in the STM32F303 to amplify and measure some low voltage signals (100-200mV with a gain of 8 or 16) coming from a temperature sensor. Doing so on one channel works fine, and I am able to get accurate readings once...
Hi everyone, I have a strange behavior with STM32F4-DISCOVERY I2C communication.My system includes an STM32F4-DISCOVERY, a BLDC motor, a flow sensor (SDP601), and a pressure sensor (MS5525DSO). The motor works as a blower and 2 sensors measure the fl...
Posted on May 09, 2012 at 00:56One of the areas I'm looking at with the STM32 is being able to transfer files (or at least data) from an IrDA dongle from Windows to the STM32. However, as I understand it, the STM32 only implements the PHY layer usin...
Dear All,I need to a get a delay of 5 microseconds using STM32F407VG Discovery board. Is using a timer a good option for this or there is other ways available to solve the problem without using any external library?
Posted on April 17, 2017 at 19:54I am looking for the max and typical update times for the LPTIMx_CMP and LPTIMx_ARR registers on an STM32L4x. I don't see these listed in the reference manual anywhere. Additionally, are there any settings or device ...
There are multiple references in the documentation that allude to being able to do two flash operations in parallel on the STM32H743 as long as you are doing these operations on different banks.For example, the reference manual RM0433 Section 3.2 sta...
