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 August 07, 2013 at 06:47 Our requirement is to configure the DMA so that it transfers data from the GPIO lines (8 bit data lines) to the RAM buffer upon receiving a trigger signal on the timer capture input channel.We had received an exa...
Posted on November 14, 2015 at 19:02Hi.I'm using timer in PWM mode to control LED. If output is always 1 (CCR register is equal to ARR), LED is green. If output is 0 (CCR is always 0), LED is red. If I set duty cycle to 50% at high frequency, LED is...
Posted on July 13, 2014 at 15:52 I used STM32CubeMX for a configuration of RTC in STM32F405RG on the OLIMEX STM32-H405 board. It seems that RTC does not work although the OLIMEX example works. For sure, I tried LSI also. I watched the ''time...

Posted on November 16, 2015 at 15:08Hi everyone,I am using the STM32L152 MCU. I am trying to implement a watchdog on my low power module (in stop mode).The device only wakes up on interrupt in order to optimize power consumption.I saw differents top...
Posted on November 14, 2015 at 19:02Dear all,Is there a way to use the Class D functionality in the CS43L22 audio codec on the STM32F407 Discovery Kit? I have been looking at the schematics for some time now, but it seems that the SPKR A+, A-, B+, B...
Posted on November 09, 2015 at 12:38I have been trying extend Clive1 ADC_DMA example on STM32L_Discovery to do multi-channel conversion. But am struggling to get the NVIC_IRQ Handle for the two channel right. Can someone assist me with an example of...
Posted on October 30, 2015 at 10:17Hi, When generating a new MDK V5 project with Cube V4.11, the ''Name of Executable'' in ''options for target/output'' will left empty but t his is a mandatory field and need a value. Normally is this value ''[Proje...
Posted on November 16, 2015 at 03:24Hello all,I'm having another strange issue, when an update interrupt happens, neither the instruction ''__HAL_TIM_CLEAR_IT(htim, TIM_IT_UPDATE)'' (line 2869) of the hal_tim.c library or my code in the callback fun...
Posted on November 15, 2015 at 23:34I have a Nucleo F411RE board and eventually want to program it with code generated by the MikroE Pascal for ARM compiler. At present I have the board running code from the MBed C++ compiler and the programming si...
