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...
