STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
Posted on September 03, 2014 at 19:53Greetings all -- I have a custom board built around the STM32F303VC, which has separate pins for VDDA and VREF+. In the interests of keeping the voltage reference quiet, a 3.0V regulator is attached to VREF+, an...
