Posted on March 26, 2015 at 09:56 I use STM32F4 I set MCO1 to PLL Clock and set output prescaler to 5 and I have 6MHz on my MCO1. There is no problem in it, But when I enable LSE with HSE together, I have no signal on MCO1 pin. Code: ...
Posted on March 25, 2015 at 13:32Hi Issue:Using USART, configured as a normal uart full duplex, we see that the TX pin from the MCU is floating after the stopbit. This seems to be causing issues in some cases.Question 1:What is the default behavior ...
Posted on March 20, 2015 at 15:02Hi,I am having a problem with RAM shortage on 32F429IDISCOVERY because of a complex processing algorithm. Generally speaking heap crushes into my stack and hard fault is called. The algorithm that I use cannot be cha...
Posted on March 26, 2015 at 11:38Is there a way to tell if the reading in the real-time-clock is valid - i.e. that the clock has kept ticking since the last time it was set?My board has a STM32f405, and its backup domain is powered by a Supercapacit...
Posted on April 29, 2014 at 15:01Hello, I have to develop a board to attach to an STM32F429 Discovery kit to control a comercial display. In the design i found that the pins of the discovery kit give only a certain funcionality. Is not other way of ...

Posted on March 27, 2015 at 05:21I have developed a stm32f207 board for my own application. I have interfaced a 14 bit grayscale camera using DCMI. I'm then transferring this image to the SRAM using DMA. The SRAM being used is the same present on th...
Posted on March 23, 2015 at 08:53Hello. I'd like to know how to refer values of variables. My understanding is all of variables are seen in a variable scope when I stop a program, but at the moment, I can't look at some variables I defined. Could so...
Posted on March 26, 2015 at 09:02Hi,I want use I2S function on ST411I2S1(SPI1) can work on DMA Mode?I check DMA1 request mapping Only have I2S2 , I2S3 but in my design need SDIO (SPI2,SPI3) #i2s-stm32f411
Posted on March 26, 2015 at 15:48Dear All, I am new to an embedded world in general and to the STM32F4xx controllers in particular. In order to learn the trade, I got the STM32429I-Discovery board and along with the hardware, I have installed: ...
