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...
Hi,I want to realize ir transmitter with pwm signal but i do not understand the basic principle of pwm ir transmitter. What is the right way for creating ir transmit signal with pwm? Which peripherals must be used for this( pwm, timer interrupts...?)
Posted on January 26, 2015 at 11:58 Hello List, I,m struggling with reading, without DMA, from multiple channels. Every, say, 10 msec I call: var1 = Get_ADC_Value(11); var2 = Get_ADC_Value(12); Both variables ALWAYS get ...
Hi All,I'm trying to implement the eval board for a project seems like they have used a lot of different types of memory from HW perspective. I wanted to know what memory is being used for what purpose for this specific board so that I can change it ...
Hi,I need to generate a special waveform via DAC on a STM32F446. DAC samples must be generated at about 240kHz but with minimal jitter. A DMA channel with timer trigger will provide the data from internal RAM or flash. What best case - minimal - jit...
