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 06, 2014 at 09:02Hello all. I just got a STM32F429-DISCO board and compiled my first successful program. I'm working under linux compiling with the GNU toolchain for ARM. In order to be able to compile my program, I had to modify...
Posted on November 27, 2014 at 13:51Hi, i am trying to generate an Signal with 50 % duty cycle using PWM Mode 1 Timer 1 channel 1.Pls go through the code below.I can't generate any pulse at PE9 PE9 is used as timer 1 channel 1 PWM OP. Usi...
Posted on January 24, 2013 at 03:46Hi, I have just saw a program about a interrupt time. The program can let the LED on and off in a specified period. But I have some question about the prescaler value, can anyone help me to understand the prescale ...
Posted on November 29, 2011 at 17:56 Our design is made with a STM32F207ZG microcontroller and we have some problems with the RTC peripheral. We have an external 32.768 kHz oscillator (LSE). Using the ST library, the initialization of the R...
Posted on November 27, 2014 at 11:15Hi,I am currently using the dsp library .I noticed that it need math.h library to run correctly.Unfortunately, i couldn't find it on the internet.Does somebody have a link?
Posted on November 27, 2014 at 11:25Good day,Given you use the RMII interface to the STM32F4 MCU does anybody know what the CR (clock range) needs to be configured to? The RMA is not clear if the clock range configuration is for the MII interface o...
Posted on November 27, 2014 at 10:48 I found an example in the stm firmware. It is TIM DMA Burst. The configuration code is as in this link https://github.com/devthrash/STM32F4-workarea/blob/master/Project/STM32F4xx_StdPeriph_Examples/TIM/TIM...
Posted on November 26, 2014 at 11:11Hi, I am very new to 32 bit micro-controllers.I am using STM32f207VG controller.I want to use Timer2 to generate Interrupt every 1 ms.Timer clock is set to 36MHz. I have written the following code for timer ISR.My...
Posted on November 26, 2014 at 10:43I have seen a lost of discussions about synchronized sampling of ADCs. But I haven't seen a single example for synchronized sampling of SDADCs anywhere. I am using stm32f373 MCU where I want to sample SDADC1 and S...
