I want to enter the CPU in stop mode and wakeup the CPU using RTC wakeup.I wrote the following code.----(void)HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 2-1, RTC_CR_WUCKSEL_2);HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON,PWR_STOPENTRY_WFI);/* STOP MODE */...
Problem with ADC reading at 100 kHz via DMA.MCU runs @ 48 MHz, ADC @ 14 MHz. Configured via CubeMX.Trying to read one ADC channel (1.5 cycles), triggered by Timer 15 (100 kHz) using HAL.Cannot reach 100 kHz (see pictures). Blue are DMA interrupts (h...
I am trying port sample code via usb fs of STM32H743 MCU. I have installed dfuse in win7. But my device is not getting detected. In deVice manager I see warning mark on STM device in DFU mode. If i check the details, it says digital certificate is no...
If you compare the code from e.g. the STM32CubeF2 and STM32CubeF4 archives you'll see that its almost identical. The only differences seem to be the name of the files and defines (have F2 or F4 in them) and the F4 code containing some additional fun...
I use the BSP functions to record audio. The sampling frequency is set to 8000 Hz and the buffer size to save the recorded data into is set at 8000 elements long. It would make sense if the time to fill up the buffer is 1s. However it takes exactly 5...
I have been using Atollic TrueSTUDIO for STM32F3DISCOVERY applications to write and test algorithm for a client. After successful debugging and testing I have to handover the project to the client. However I cannot reveal my source code which is actu...
In the STM32l476, I have found that the VREFBUF_CSRregister 'HIZ' bit is being set from default 0 to 1 when SET_BIT(RCC->APB2ENR, RCC_APB2ENR_SYSCFGEN) is executed. RCC_APB2ENR_SYSCFGEN is the LSB.
I bought Discovery kit for LoRaWAN™, Sigfox™, and LPWAN protocols with STM32L0 . Then I read https://github.com/aureleq/muRataSigfox . This is about my same kit. I was able to register it with Sigfox. More, I read http://blog.aha.nl/2018/02/getting-...
Hi,Our device sometimes turns on from Standby by itself. The only wakeup sources enabled are a couple of wakeup pins.I saw the device reset (from standby) by itself, and the PINRSTF flags in RCC->CSR was set. The reset pin has 100nF capacitor to Gnd ...
Hello,I have been using STM studio for monitoring run time behavior of a software for STM32F4 and I have noticed that traces of some variables contain abrupt changes to zero value. The zero values are displayed despite the fact that the actual value ...
