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 September 18, 2012 at 21:20Hi, as i know stm32 operations alway read-modify-write. Not atomic. If i read below it looks like C is already atomic for some operations. Or is it not guarantee on stm32 platform? http://www.informit.com/guides/...
Posted on September 21, 2012 at 18:08The ST32F4xx user manual, RM0090, on page 205, for the EXTI_PR (pending register) bits says: > This bit is cleared by writing a 1 to the bit > or by changing the sensitivity of the edge detector. The latter one ...
Posted on September 21, 2012 at 10:44Hello,I'm currently trying to implement a UART driver with interrupt handling for the STM32F100RB on my Discovery board. Therefore, the function UART_Init() configures the UART1 and enables the interrupts TC and ...
Posted on September 21, 2012 at 15:07When I program a GPIO pin, I have to define a ''speed'': 2, 10 or 50MHz. What does this mean in terms of hardware? Is this a filter? If I program the pin with 2MHz I can't output a signal with 5MHz. What is the h...
