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 July 03, 2013 at 22:30Hello, I wonder if there is any predefined protocol for In Application Programming of the application from ST available. I am looking something similar that does avrdude AVR109 for AVR controllers. I would like to sta...
Posted on July 02, 2013 at 22:09Hi,I am working in a USB Device project. The idea is plugging the device in the PC via USB cable in order to mount a drive unit. Data is storaged in a SD card through SPI interface. I am using STM3210C-Eval board and ...
Posted on July 02, 2013 at 08:44Hello I am using IAR embedded workbench tool and STM32W108XX device for development purpose. When I program it I got error message as No reply received.. Error while initializing interface. Please help me as...
Posted on July 03, 2013 at 01:44Hi all, i'm using STM32F407 with 12MHz ext. crystal with 168MHz system clock, i use demo for STM32F4Discovery, i configured Timer4 and Timer8 in same way, specifically: ARR=1, PSC=0, CKD=0, and i'm measuring 42MHz o...
Posted on July 03, 2013 at 10:29Which IRQ do I need to use ? I don't see any IRQ related to TIM9 at stm32f4xx_it.h.TIM8 can also do PWM input - which IRQ do I need to use there ?void TIM8_BRK_TIM12_IRQHandler(void); /* TIM8 Break and TIM12 */v...
Posted on July 03, 2013 at 06:21Hello, I'm on stm32f3.As far as I know, comparators on the device is very fast so it's very suitable to detect short circuit and over current condition in 50 ns. but most of shunt resistor has very LOW value. so it sh...
Posted on May 28, 2013 at 22:42 Take a look at the video below, which shows Linux, in its uClinuxform, running on the STM32F437 microcontoller: http://www.youtube.com/watch?v=_uO8KfhfY2Y&feature=youtu.be The novelty of this con...
Posted on July 02, 2013 at 20:57In a project I have a periodic interrupt (5ms) that misses a beat from time to time (1-2min).I have an os that will globally disable interrupts (set primask to 1) for very short time then re-enable them. I suspect it ...
Posted on February 24, 2013 at 02:29Hello everyone. As many may have noticed, the STM32F4 discovery boards comes with an unfitted OSC32 crystal (X3) & biasing caps (C16 & C27). Did anyone ever tried to provide her/his the board with those missing c...
Posted on July 02, 2013 at 10:46 Hi, I connected the ethernet port of the STM32F10C-Eval to my pc using an ethernet cable. But the led of the ethernet port is not blinking which means that the connection is not detected. I have changed the cable but...
