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 15, 2013 at 11:54Hi to everybody, does anyone knows if is it possible to read the pin's state when the GPIO is configured in output mode? I made a quick test, and seems not to be possible.
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...
