Posted on May 27, 2013 at 16:50 I test the microphone[MP45DT02] of stm32f4 discorvery board. I use 1.024Mhz Clock input microphone with i2s signal. Pmd fiter of library is applied and get pcm data from pdm data. Is it corret pcm data that no sou...
Posted on May 30, 2013 at 16:21Hi,Stm32l1 consumes much current than I expected. In standby mode, I measure 6uA consumption for my board but when I put it in stop mode it consumes 480uA. It should be around 10uA.The configuration is; USART_ITConfig(...
Posted on May 31, 2013 at 05:46Does LibPDMFilter_IAR.a in the STMF4 DISCORVERY is used for all STM32 family? for example, Is LibPDMFilter_IAR.a used for STM32F1XX not STM32F4XX????
Posted on May 30, 2013 at 15:28 Can I2S3 be configured as Rx slave, with an external clock ? RM0090 says nothing on the contrary, but looking at the stm32f4xx_rcc.h include file I see this definition, which relates to I2S2, but there is not ...
Posted on May 30, 2013 at 02:28I've got several Discovery boards (2 F4s, and some others). I've got the last version of the Atollic Truestudio Lite IDE before they added a code size limit, v2.3 I think, installed on 3 PCs. I hadn't used them for man...
Posted on May 30, 2013 at 12:28Hi, I believe that FS is USB1 and HS is USB2. I have FS running in my project but can't seem to get HS running.I can run this ST sample on the f4 discovery board: http://www.st.com/web/en/catalog/tools/PF257882I have t...
Posted on January 20, 2013 at 15:12Hi all, I use the STM32F4Discovery Audio playback and recording example. I sound 1KHz from speakers and record the audio. The wav file I get is filled with click sounds. Also if I modify the code and keep everythin...
Posted on May 29, 2013 at 15:22Hello, we want to implement a pulse generator with Timer1, clocked by SYCLK. For marketing reasons we'd prefer a granularity of 10ns, therefor we'd set SYSCLOCK to 100MHz. At the same time we'll need a USB CDC for our...
Posted on May 28, 2013 at 12:58Hi, I'm fairly new to the world of microcontrollers. I'm using the STM32F103ZG on the MCBSTM32E development board and am saving user-defined inputs to the BKP registers. Most inputs are positvie, small integers. Howeve...
Posted on May 16, 2013 at 16:10Hi all I've some troubles with the internal temperatur sensor from my stm32f051: If I read the adc_channel16 I get ~1920 as value. Then I calculate the result in this way �C = ((V25 - VSENSE) / Avg_Slope) + 25 = ((1.43...
