Posted on August 27, 2013 at 11:03Helloi wanted to design usb3317 for my stm32f407 but there are some problems.i read something about OTG,that there are A-device and B-device but i dont know how to design them to work together on the board.please so...
Posted on August 26, 2013 at 22:06While dumping some memory from the CCM on an STM32F405 at address 0x1000 FF00 I noticed the GDB memory browser window cut off at 0x1000 FFEF as the end of valid memory. The last 16 bytes of CCM didn't show. Has an...
Posted on August 26, 2013 at 15:47Hi thereI'm still a bit confused about whether I have to connect the nRESET pin of the 10-pin Cortex Debug Connector to the NRST or the NJTRST pin of the STM32 in case of both JTAG and SWD connection. Could anyone t...
Posted on August 15, 2013 at 05:55Hello: Today , I want to capture the high-level length of input signal using TIM5 Channel 1 (PA.0) in chip (STM32F103ZET6)?but why program can not enter TIM5 interrupt service ? please help me ! I have attached ...
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 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...
