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 May 24, 2018 at 12:03I have designed a board using the STM32H743II. During integration testing of the software I have found the following issues related to the microcontroller (SCB->CPUID 0x411fc271) :1)SPI1 and ADC1 is not working when us...
Hi,I am having problems sending a part of an array with SPI. It is no problem to send 4 Bytes from the beginning of the array, but if I want to send 4 Bytes from another starting position (for example: start from tmp[1]) it does not work. In this cas...
Hey, I want asking something, I have a value on backup register, but when the tamper is active when power off, the value on my backup register was reset. On datashet get to protect the backup domain no erase or mask flag bit must enable. I set the no...
Hi,i use STM32CubeMX and Keil 5 for my embedded project and now I want to create a Desktop GUI using QT to command STM32,I want first to just create 4 buttons which correspond to 4 leds of the STM32F4 Disco Board,Please can anyone help me:Environm...
I am trying to generate 4 channel signals using Timer 1 (due to the need of Dead Time) and am facing a problem with the output. Even after defining the timer output compare polarity and all, sometimes the signal just dephases (or in other words shift...
Posted on July 02, 2017 at 05:34Hello,I recently migrated to STM32 Platform and I'm trying to learn all the Peripheral features without using Standard Peripheral Libraries. Problem Statement: I am not able to get PWM output on timer output channel...
I have a STM32F072RB that came with a touch sensor on it. What I want to do is to use it as a input to implement something like a volume silder. Anybody knows how I can get started? I found some an example from ST where the touch sensor is used as a ...
Hey there,I can finally send lin messages from stm32. But now i want to receive and handle received LIN messages. But in datasheet of mcu says receiving is totaly independent from normal usart receiver. I can not find any example to receive interrup...
I have an application where in "run" mode alot of current is needed at 3V3, so there is no way around a 3V3 switching regulator in the circuit. In the sleep mode, i don't need any pheriperal power, the main switching regulator would be turned complet...
Hello:Using a single timer (TIM2) on an STM32L4, can the IC be set up so that it can function down to 300Hz, while the PWM is generating 20KHz?Using CubeMX to do the device setup. I can not change the counter period as it is set correctly to generate...
