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 12, 2013 at 10:44 So, here the situation. There is high priority asynchronous external interrupt and low priority systick interrupt. In EXTI handler I disable all interrupts and make pulse on test output 1 In S...
Posted on September 13, 2013 at 17:54hello everyone,Now I use stm32f4 discovery. I want to use ADC example ''ADC_DualModeRegulSimu'' from the StdPeriph_Lib_V1.1.0 Project.I have following questions:1. They use ADC Dual Mode with DMA, but they don't ...
Posted on September 16, 2013 at 23:19Hey there,is there any way i can implement a GUI with my stm32F3. I am using KEIL at the moment as a debugger and code-uploader.Martin
Posted on September 16, 2013 at 20:54Hello my dear Forumers,I'm having difficulties to understand the Update Disable bit and Update Request bit.In the peripherial libs it is said, and i quote:Configures the TIMx Update Request Interrupt source. * @...
Posted on September 13, 2013 at 15:37Hi forum!I am trying to launch a soft reset of the STM32F417 core without losing peripheral state or resetting the peripheral registers. I intend to jump from one application (in flash) to another (in SRAM), for ...
Posted on September 12, 2013 at 23:49Hello, I have problems to set up the right pin state while TIM2 is configured in PWM mode and turned off. The corresponding CC output pin stays HIGH while timer is off but I strongly need it to be LOW. I thought ...
Posted on September 15, 2013 at 19:30Strange! I2C1 stop working after code passed 8Kb when int vect reallocated to 0x4000I am using a USB bootloader, and all the sources must be compiled with interrupt vectors realocated at 0x8004000. After the comp...
