Good afternoon,
I am trying to port an application I wrote for the STM32F407 Discovery board, which makes use of the ADC, DMA and NVIC to the STM32F429 Discovery board.
I receive a lot of errors wh...
Posted on June 27, 2013 at 00:37Hello, the I2S interface is specified up to 192kHz, and actually the stm32f4xx_spi.h file has defines from 8kHz up to 192kHz. I am wondering if anybody has ever tried to push the I2S interface up to 384kHz (and po...

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 15, 2013 at 19:00 I need advice on the following problem. I have to connect an external hardware generating 32-bit values at a continuous rate of 1536 kHz to a GPIO port of a Cortex M4F CPU, that of the STM32F4 Discovery board, which I...
Posted on May 13, 2015 at 00:55You are quite right... I am having problems, as I need to use the touch screen with the emWin libraries, and this implies the use of some functions of the STM32Cube. Naturally, the includes of STM32Cube are not compati...
Posted on May 11, 2015 at 22:12Clive, thanks for your answer. The problem is that the define USE_STDPERIPH_DRIVER actually IS defined... as is the processor STM32F429_439xx... using here the Keil uVision IDE, and I have just checked for those se...
Posted on June 27, 2013 at 22:30> 768 KHz @ 32-bit (16+16) would be workable, however @ 64-bit (32+32) your bit clock is pushing > 49.152 MHz which is beyond the expressed limit. I'll presume you're stuck at audio rates? No, audio does not enter ...
Posted on June 27, 2013 at 18:01Clive and Jan, thanks indeed for your suggestions and help. After all, it looks like it can be done... I will contact immediately the FPGA programmer to talk him into modifying his code to give me rates of 384 and...
Posted on June 27, 2013 at 13:14> Perhaps you can restate the question, the bus can clearly go above 384 KHz, but that refers to a > audio sample rate at some bit width and channel count. You'll need to quantify those requirements. Presently I u...
