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...
Posted on November 13, 2013 at 13:07Hi everyone, I'm currently working on a musical (using midi) project on which i need very precise delay in order to synchronise with other instruments. This delay should be able to be accurate at 1 microsecond. Fo...
Posted on November 12, 2013 at 15:54 Hello, I'm coding a real time system based on STM32F427 requiring a lot of ressources and using almost all peripherials (ADC, DAC, SPI, I2aC, USART, USB, SDIO). This is why I want to reduce the ressou...
Posted on November 15, 2013 at 10:31I am working on the SPI communication between PC and STM32F405RG MCU. FTDI chip FT232H serves as a bridge between PC and MCU (USB to SPI converter). FTDI is set to be SPI master and MCU is slave. I am using DMA tr...

Posted on November 13, 2013 at 01:03Hello experts,I'm trying to get SPI with DMA running on my STM32F3board. So I wrote this code after a tutorial and the StdPeriph Lib. To test the SPI parameters I wanted to send a 16 bit value and watch on the bu...
Posted on November 15, 2013 at 04:56Hello,I have been busy these past days trying to understand a problem revolving around this simple algorithm : every second write a byte through SDIO using ST DMA2 example. Using a simple loop in main works perfec...
Posted on November 13, 2013 at 11:03i use my own board and try to use SD card to update IAP when i try to erase/write flash the function always return ''flash_error_program''i checked flash->sr value is 0xC0, but i just follow the step with stm32f4_...
Posted on November 13, 2013 at 23:43I can successfully load the code from stm32f407 processor to stm32f100 in my project by using f100's bootloader firmware and RS232 protocol. However, I used the same(similar) way to load the code to stm32f303 proc...
Posted on November 13, 2013 at 21:16 Has anyone managed to connect a ULINK2 (or other JTAG debugger) to the STM32F429 Discovery using CN2, if so, how? Yes, I know the Disco comes with a ST LINK V2 interface, and that works just fine, for now. But, e...
Posted on November 14, 2013 at 14:57Hello everyone,I've been trying to discover the STM32F4-Discovery features and peripheral examples of its firmware package lately. I'm having trouble with the ADC-DMA example. Actually, I wanted to observe only co...
