I have been told i need to sync 2 STM32 MCU's together (on the same PCB) to stop an intermittent I2C bus failure between them. At the moment they are operating on separate 8Mhz crystals. I have used the following command to configure and output the 8...
Hello, guys.I need to improve one old project. There is no free pins on MCU left, except PC13-PC15 and I need three external interrupts. Code with initialization for making PC13-PC15 as inputs lower. I do not use LSE or RTC anyway.For PC13 all works ...
Set up TIM4 to generate a hsync pulse of 2us RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE); TIM_Cmd(TIM4, DISABLE); TIM_TimeBaseInitTypeDef timerInitStructure; timerInitStructure.TIM_Prescaler = 0; timerInitStructure.TIM_CounterMode = TIM_...
I'm looking for any potential vendors where I could host a cloud VM for doing automated STM32 builds coupled with some infrastructure for managing releases? Any recommendations?
Is it possible to write a custom loader (.stldr) for internal and external (qspi) flash? If so, any tips?I'm following this guide:https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/external_QSPI_loader.htmlThis is a tou...
Hello all,I thought this is a straight forward thing but for me it turned out not to be...What I want to do is simply using SDADC1 and SDADC2 and perform a regular conversation at a time in multimode. I configured both in CubeMX and tried to sample b...
Hi, I have a question about preprocessor C. When I define macros like:#define CON_A 10 #define CON_B 5.6 #define CON_C 20.896 #define MY_MACRO (((10* CON_A)/CON_C)*CON_B)The last one is precalculated by the compiler or is just plain replaced as it...
I mean, I setup TIM1 CH1 as output PWM, One pulse mode, but I need to trigger it by my codesfor example which register should be set to high or low to generate a pulse on TIM1 CH1
This is the sequence of events:Enter Shutdown with RTC Wake up timer enabled (5 seconds)Brown out, remove and restore powerPOR Reset occurs, correct PWR->CSR = 0x0C000600Clear CSR flags by writing 1 to RMVF in CSRRead CSR flags and confirm they are c...
