Posted on May 20, 2014 at 11:52I just want to place a STM32F401 64pin LQFP chip on my PCB, but to my surprise this chip has 2 pin 1 marking dots, on two diagonal corners. If I position the chip such, that I can read the text ''ARM STM32F401...'', th...
Posted on September 03, 2014 at 14:25Hello Dear Community-Members,I am having a problem with the STM32F207VG generated code from STM32CubeMX and the MicroC Pro Software from MircoE.As I am new in this area I would need some help. The generated HAL f...
Posted on August 08, 2014 at 17:21Hello! I'd like to design minimal schematic for STM32F429. I'd like to have all pins connected to goldpins. I want to program through ST-LINK and SWD. Please check my schematic. It's in the attachment. Thanks! #s...
Posted on September 01, 2014 at 06:25Hello, I have a Discovery board and am using the SPI master DMA example and SPI4. I set NSS as SPI_NSS_HARD_OUTPUT. What I get is CLK, and MOSI come out perfectly, but NSS is pinned low. I put a pullup on it, and...
Posted on September 03, 2014 at 17:26I've been trying to run the system bootloader from my application on an STM32F205. I think that should b feasible, but at present the system firmware behaves badly. Probably I'm doing something wrong, but I can...
Posted on September 03, 2014 at 10:26Hello, At the moment I am designing a PCB with the STM32F4 and PSRAM. Are the FSMC_NEx signals the bank switch signals? Can I use all the FSMC_NEx signals for the PSRAM or are certain banks only for a certain me...
Posted on September 01, 2014 at 17:11Hi,I want to use 512 Mb MMC card with STM32F103VC.Hardware is ok . Do you have any ideas on this issue? any driver for STM.How can I read and write file in MMC card ? Regards,
Posted on September 03, 2014 at 00:58I'm trying to run SPI on DMA Mode for STM32F407 (Discovery). I'm stuck with the below code, with the oscilloscope showing SPI CLK but no data. I'm wondering:1. How do you do slave select in DMA Mode?2. Is the DMA...
Posted on September 03, 2014 at 23:30The STM32F4-Discovery_FW_V1.1.0 library has USB code that I'm using in an STM32F4 project for USB HID support. usb_bsp.h has the board support package function definitions. I'm implementing these for my own cus...
Posted on August 30, 2014 at 23:22Hi Forum, Is there any way to avoid returning from an USART1 interrupt? The booting process of our unit takes some time so we want to jump to the main menu quickly by pressing a key on the keyboard. This works and t...
