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 October 25, 2016 at 17:28Hi, I am trying to get interrupt based I2C functionality running on the STM32F429, eg using the HAL_I2C_Mem_Write_IT function. However the EVT interrupt that should occur to get the process rolling is never calle...

Posted on October 31, 2016 at 20:33HI,I'm trying to figure our why I'm having an issue with a I2C clock stretching problem.On my I2C bus I have various devices all work flawlessly apart from one (MCP39F521) that once you have finished a Master Trans...
Posted on October 18, 2016 at 02:36Hi everyone, I'm a bit puzzled when I'm looking at the pinout part of the STM32F20xxx datasheet (p. 47). In there, it says that pins PA4 and PA5 are of type TTa (3.3V tolerant) BUT have a little note (4) saying ''F...
Posted on October 25, 2016 at 04:45Hi,I am using STM32F4xx MCU in our product and there is a GSM module connected over UART2 of MCU.Initially MCU was configured to operate at 168MHz frequency and UART2 was configured for 38400 baud rate. At that tim...
Posted on November 01, 2016 at 17:28Dear all experts,I am programming Incremental Encoder Reading project for 2 encoders.I intend to use TIM2, and TIM3 for Encoder Config with 4X Reading. I check the datasheet (DM00105814) for MCU Pin configuration....
Posted on November 01, 2016 at 16:12Hi everyone, I have a general question regarding the sampling time when triggering ADC in DMA mode by using a timer event update. Let�s say I have a DMA buffer with size N. Is it possible to take one ADC sample pe...
Posted on October 29, 2016 at 11:30Hi everybodyI need to get PWM input value using input capture .I set Input Capture in Both Edge mode and I'm getting the HAL_TIM_IC_CaptureCallback very well . but for calculating the PWM duty cycle I need to know ...
Posted on November 01, 2016 at 15:50Dear all, I have an issue using the option bytes to set the program flash write protection during a firmware update through IAP (in application programming). My devices are STM32F427ZI and STM32F429NI (Eval-Board:...
