Hello,i want to use a really precise PWM signal but i get a lot of Jitter on it.I am using the F410 with a 16Mhz crystal. The PLL produces from there a Frequency of 100Mhz (I need this high frequency for my other tasks).The rest of my hardware needs ...
I want to read Temperature data in register [20h,21h] , but the data I read are 0x00 , should I setting which register ?
Hello,I am using the STM32F107VCT6 microcontroller and, under normal circumstances, it works flawlessly. However, I have been encountering an issue where data in a specific memory area becomes corrupted when I toggle the nRESET pin at 2-3 second inte...
Hi，I am working with STM32H5RBT6U：How do I calculate the frequency of the I3C Controller? Is there documentation to cover the content?I tried using CubeMX to set the frequency, but strangely, all the frequencies work fine except 3~5MHz. The exceptio...
Working with the RTC I'm having some issue with the callback only being called a single time. void HAL_RTC_AlarmAEventCallback(RTC_HandleTypeDef *hrtc) { RTC_AlarmTypeDef sAlarm; uint32_t hobb_time; __HAL_RTC_ALARM_CLEAR_FLAG(hrtc, RTC_FLAG_AL...
This might be a really stupid question but I recently downloaded RM0090 revision.19 for reference in use of timers in STM32F407IGT6.But I have noticed some diffrences from old reference manual & I can't find revision history for that. Old revision of...
Posted on July 12, 2017 at 21:23Hi,For the STM32F7xx family, the UART HAL library includes in its public API the function UART_SetConfig(), by which certain UART parameters can be modified at run-time, after the initial configuration (baud rate, par...
Posted on January 09, 2015 at 16:49Hi I'm a newbie to stm32 , I have a STM32F4 Discovery board with me. So what I want to do is to generate 2Mhz,4Mhz,8Mhz square wave on any of the Pins on the Header. Can you please provide some sample code for th...
I'm using an STM32H725ZE chip. I know that PA15 defaults to JTAG pin JTDI, but the datasheet for the part specifically says this:In SW-DP mode, the unused JTAG lines JTDI, JTDO and nJTRST can be used for otherfunctions.I'm in SWD mode because it's a ...
Hi I am programming a STM32L433 and have the processor wakeup from Standby mode. The first thing it does after wakeup is check the cause of the wakeup, and if RTC increase the time, do a few readings and go back into Standby mode. When I am running ...
