Posted on February 13, 2014 at 09:33Is there a need to erase a sector of the internal flash memory of STM32F40xx-Devices before writing new data to that sector? I couldn't find a hint in PM0081. The flash_program example of STM32F4xx_DSP_StdPeriph_L...
Posted on February 12, 2014 at 14:42Dear all, I am using the STM32F429i-Discovery, and I experience some problems with UART communication: received symbols are differents from TX. Discussing with some colleagues points out the baudrate might be in ...
Posted on February 13, 2014 at 22:59Hi forum!Here is a very strange problem I'm facing with the SPI1 peripheral of the STM32F417 connected to the LIS3DH. I have to single-step through my code with my debugger in order to get the right data from the ...
Posted on February 08, 2014 at 20:52I'm currently testing I2S between two F4 Discovery development boards.One board is master, running DMA, one is slave. Both are configured with the same sample set for verification purposes, so the data sent can b...

Posted on February 13, 2014 at 14:07I've set up my DMA to transfer 106 half-words via the SPI to a memory buffer. I am quite confident that my buffer size is correct. However, when the transfer actually occurs, it is twice the size I expect (and is ...
Posted on February 13, 2014 at 20:30Hello, I am working on the STM32F429 with Keil uVision version 5, and am trying to get the USART1 module working. In attempting to use the functions provided in the stm32f4xx USART library files, I am getting very...
Posted on February 13, 2014 at 14:00I use stm32f4-discovery board. I am working with the ADCs, and for my prpose I need to set the ADC reference VREF+ at 3.2V. in the reference manual RM0090 it is said that stm32f4 LQFP100 has VREF+ VDDA pin. But th...
Posted on February 12, 2014 at 18:03I'm using custom code which is somewhat ported from the STM3240-G USBD-MSC example application. I also made modifications to the read/write functions to take blocks as arguments vs. bytes. I've stepped through the...
