Posted on August 26, 2013 at 15:20 Hi , I am having a little bit of trouble configuring the audio codec (cirrus CS42L52) on the MCBSTM32F400 (stm32f407IG) evaluation board . I am trying to do a reset to the codec via the reset pin , but looking fro...
Posted on August 26, 2013 at 09:42At first glance, this technology seems too good to believe. I suggest you add a ''Customer Case Studies'' page to your stm32java.com website. In this page, you can list some real world products/applications using st...
Posted on August 22, 2013 at 16:35Hello Everyone, I am using stm32f407 which is interfaced with 1MB of external RAM. Linker script is a simple one where it puts the data and bss section in external RAM. Regarding code execution I don;t have an issue...
Posted on August 25, 2013 at 14:46I'm new on STM32F407 and STM32F4xx DSP and Standard Peripherals Library. And now I've got some question.1) GPIO timingWhen I code GPIOF->BSRRH = 0x0100U; GPIOF->BSRRL = 0x0100U; GPIO...
Posted on August 24, 2013 at 07:54Hi, I can't find any basic assembler example for stm32f4 in keil, i would like an example to start with basics like configuration ports( in/outs) to on and off a led with a button. #assembler-keil
Posted on August 24, 2013 at 19:12Hi all,I'm designing a MICROSD SDIO bus on a future PCB with a splitted ground plane below all D0-D3, CMD, CLK and SD_VDD to decrease noise, but I can't find a way to ''totaly'' cover the D0 and D1 traces (LQFP64 ST...
Posted on August 24, 2013 at 18:41Hi there, If I setup both ADC1 and ADC2 in independent mode and set ADC1 to scan channels 1,2,3 using DMA and setup ADC2 for analog watchdog on channel 2 having different sampling times for channel 2 between the ...
Posted on August 23, 2013 at 15:59In my application I'm sampling a 50Hz voltage at 300Hz in a timer interrupt. My application is able to alter a part of the flash memory to save parameters. But during during flash write/erase activity the CPU stalls...
Posted on August 23, 2013 at 12:48Hello again, I have connected two STM32F2 via SPI1. The data will be transfered via a variable sized datablock. The first two bytes are a command (5 bit) and a length (11bit) information of the following block. Is i...
Posted on August 23, 2013 at 09:39I think ITM_SendChar is freezing my code when I don't have a debugger attachedWhen I do have an debugger attached, it works, and I can see my messagesBut when I don't, then the code doesn't get past the printingBut ...
