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 February 14, 2014 at 18:01Hi All,reading the reference manual of the STM32, I have a question related to a transfer peripheral to memory using DMA, direct mode ( no FIFO )In section 9.3.12, Direct Mode paragraph, i found:Direct modeBy defa...
Posted on May 28, 2014 at 20:27Hello again Gentlemen!I would like to download some sample code to help me to program the USB peripheral to use it as a Virtual COM port. I guess on the PC side I have to install the ST Micro Virtual COM port driver, r...
Posted on May 28, 2014 at 00:02Hi,I'm trying to configure the UART in DMA mode, but I cannot get the interrupts to work.I have attached my code.Any help will be appreciated.Thanks
Posted on May 29, 2014 at 18:20Hi,I am unable to get the serial port receive to work with this EVAL board. It also does not work with the UART_Hyperterminal_IT example in the STM32 CubeF4 version 1.1. Transmit works fine, and it generates the TX c...
Posted on May 29, 2014 at 16:15I need some help in understanding the Bus Turnaround time of the FSMC. I think I have it right, but don't want to burn out the data bus in finding out I'm wrong. Could someone who knows, confirm please? My STM32F207 ha...
Posted on April 18, 2014 at 22:04Hi I configured the timer in encoder mode with prescaler:RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE); RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_P...
Posted on May 12, 2014 at 05:38Hello,before STM32Cube, my code would try to iterate with the computer right after USB configuration.With the code converted to STM32Cube, it does not. I have to unplug and replug USB. How could I force the MCU to try ...
