Posted on February 09, 2018 at 02:17I use DFSDM(at STM32L471RE) to record voice. the human's voice is record OK. but I can not record the heartbeat voice. it is about 500Hz.So I want to read the PDM data and analyze at PC.How to get the PDM data?I t...
Posted on February 09, 2018 at 00:14Hello,I consider to start a new project using the STM32H743. In my project I would like to connect an external camera with external syncs (8 bit) and also use some external RAM for data storage + SPI + UART + 3 pi...
Posted on February 09, 2018 at 06:53 ST is to be complimented for three specific design improvements apparent in the 769disco. FIrst, it actually has a connector to the display, rather than the LCD cable being soldered directly to the board, as i...
Posted on February 09, 2018 at 01:13HiI am using ST-LINK to program a STM32F103RBT6. I program it and the unit runs - then I set option bytes via the menu for readout protection and the unit stops. Power cycle et al does not recover. Are there ot...
Posted on February 11, 2018 at 22:27Hi there, im trying to work on some UI for the stm32f429i with StemWin. I set up everything with this tutorial http://slemi.info/2017/07/01/stemwin-touch-screen-stm32f746g-dicovery-part-2/Everything's okey but in ...
Posted on February 11, 2018 at 12:36I'm need to generate N channel (N>1) PWM output in a such a way that one channel is main 'governor' lets say ch0. Every other channel repeats the same duty, but with time shift (or or phase shift). Ch1 need to set...
Posted on February 07, 2018 at 04:36Hi,We designed a new PCB for the STM32F205RGT6, but we�re having trouble toggling GPIOs using the chip.We wrote a simple program that toggles a GPIO every 250ms, we confirmed that the code works on the http://www....
Posted on February 11, 2018 at 19:03What is Software NSS and Hardware NSS in SPI? Which Nss mode should we select?Do we need to connect the NSS pin (between master and slave) in Software mode?I read the NSS pin management in Reference manual, but I ...
Posted on February 11, 2018 at 15:00Hello everyone. I have encountered problem with USART1 on STM32F446RE. It seems it doesn't work for me. I have used multiple times USART2 and it works as it should, but USART1 with same configurations just refuse ...
Posted on February 11, 2018 at 08:07Hi, I'm interested in better understanding how SDRAM works with the on the STM32F4 Discovery development boards. For example, I have an STM32F429-Discovery. It has 64-Mbit SDRAM on the board.I've closely examine...
