I am doing some characterization study for the cache behavior on STM32F7508. The result is hard to understand.Below is a simple code that I use. I align the array A1 to the cacheline (aligned(32)), and it is placed on SRAM1 above TCM (0x20010000~ ) w...
Hi, I have a design where I have multiple GPIO interrupts and some share the same interrupt input line, for example EXTI10_15. How can I differentiate in the interrupt callback routine which GPIO triggered the interrupt aside from reading these GPIOs...
Hello together,currently I'm facing a very strange issue:I'm working with an STM32F777.One GPIO of the MCU is used to enable the voltage to a sensor. This pin is initialized as GPIO_InitStructure.Mode = LL_GPIO_MODE_OUTPUT; GPIO_InitStructure.Outp...
Hi, is there a way to change LPTIM_CNT on TIM4 so that LPTIM_CNT = LPTIM_CMP, this is because for every interrupt we need the PWM to skip some period. is there any sample code ?
In our current project, we are using the STM32G431 (UFQFPN32) with only an HSE connected. In this project, we do also need a longtime accurate RTC for Time/Date. Since the internal LSE have a quit high accuracy of 1%, they dont seem to be suitable fo...
Hello, second day try to launch UART in LIN mode.Task: waiting break, when break flag set up, switch on DMA receiver.Transmitter works fine and send 100us break before frame.But receiver can't set UP Break Flag.And there are not everywhere examples =...
Hello,I am trying to generate a unipolar PWM-Signal with an STM32f103RBT6. The Current needs to be sampled at a specific point in the PWM-Cycle. Due to the unipolar nature the current cannot be sampled at overflow/underflow. Instead it needs to be me...
Hello!As the question/topic title says, I'm new to MCU programming. I've touched C# (Unity) before and programmed an intelligent display by 4DSystems for a few applications. Unfortunately we've found some limitations on said intelligent display, so I...
Hello everyone,I am using ADC + DMA + TIMER for my analog samples on STM32 nucleoF401RE.I am new into the STM32 family.So I refer some code as per given some examples in this community.But I am not able to achieve it.I wanted to follow below method f...
