Hi everybody,Currently we have a weird thing with Ethernet on STM32H7.Everything work fine if disable cache globally.When enable cache, work fine. We can send/receive few hundreds MB or keep ping /t from PC few days, no error. So we believe we config...
In the follwoing code i would like to use same interrupt multiple times in order to blink the 4 leds different time. i am storing the data in unint8_t ABB, i expect that each time i press the button the value in ABB is incremented but practically n...
Updated Question:I have a custom PCB board with L052K8 and F051K8 with the same peripherals and correct hardware design for each (F051K8 has a VSSA for the ADC and different bypass cap), but only the L051K8 is able to program its firmware and reset c...
Hi all,I'm currently using STM32F051K8 for a smartwatch project I'm pursuing on a custom made PCB. For power consumption reasons, I wanted to change the MCU to STM32L051K8 which has the exact same UFQFPN-32 footprint.Now, my project works perfectly f...
Hello guys good day to you. May I ask you if you can share your experience on changing the frequency of a PWM using a pot. I am using a small board with the STM32F103C8 MCU. I've set TIM2 _CH1 of PA0 as output. I connected a potentiometer to PA...
So for this question, I'm using stm32l4 device. It is a Cortex M4. I've been developing with stmcubemx and Kiel compiler.I have a program that can jump to the stm32 provided dfu mode. That works great. I can update the code using DfuSe Demo.I've run ...
Hello, I have a problem with the I2C communication on my STM32F405. The F4 is running in master mode and has 3 identical sensor connected to I2C1, I2C2 and I2C3. I want to read from the sensors "parallel" 3 bytes with the HAL_I2C_Master_Receive_IT fu...
I am trying to go in standby and wake up after few seconds repeatedly with using RTC wake-up timer but I am having problem after second sleep. It goes sleep, wakes up and then goes sleep again like I expected but after that point(after second sleep) ...
Please suggest alternative to this controller.AT32UC3C0512C
What are the upper limits on the APB and AHB peripheral clock on a STM32H743 ?According to figure 46 of the reference manual:the limit is 240MHz (or 200Mhz depending on the silicon revision I assume ?).However STMicro HAL example set the APB and AHB ...
