STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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 */...
Hello.I have a problem with external eeprom.In my codes, I can read multiple datas in one time. I can't change. But I want to read/write it continous time.How can solve this problem?
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 ...
