Resolved! Issue with STM32F107VCT6 Data Corruption when Resetting nRESET
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...
Resolved! Some I3C Speed Rates are not available?
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...
Resolved! RTC Alarm EventCallback called only 1 time
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...
Resolved! Has there been any changes to TIMx_SMCR in STM32F407 series MCUs?
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...
Why is UART_SetConfig () for the F4 family declared static?
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...
Square wave of 2, 4, 8 Mhz generation.
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...
STM32H7 - Unable to use PA15 as GPIO output pin
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 ...
Cant access RTC coming out of standby mode
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 ...
Discerning Rising and Falling Trigger Edges in HAL_GPIO_EXTI_Callback()
Posted on May 03, 2016 at 00:19I have a digital input GPIO line where I need an interrupt whenever its input changes. In STM32CubeMX I set this pin to an EXTI line and set the interrupt to trigger on both rising and falling edges. When, in response ...
