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'm trying to configure the ADC to read to values at a specific time in my system that uses the STM32G474.I have two channels of peak current mode control using the HRTIMER. The outputs are reset from either a comparator event or max duty cycle compa...
Dear ST Support Team,I hope this message finds you well. I am currently working on a project using the STM32WB5MM module, and I am encountering an issue with the BLE stack initialization in my application.I have successfully installed the stm32wb5x_B...
The datasheet suggests load of 20pF .Due to size constraints, I hope to use https://jlcpcb.com/partdetail/318914-CSTNE8M00G550000R0/C341522Most 8Mhz resonators of this size seems to have 33pF
Do I understand the datasheet correctly when I believe the internal 2.1v reference is something internal, and the AD is still operating within VCC/3.3v as upper limit? Copilot suggested this: // Enable ADC1 and configure itRCC->APB2ENR |= RCC_APB2EN...

Regarding function calls when performing SPI communication in half-duplex mode.We would like to develop a product that performs SPI communication in half-duplex mode.Are there any sample programs in which the slave side transmits and the master side ...
I know that the question will be trivial, however, I do not understand why the instruction uint8_t dataRx[4] = { 1 }; does not initialize all the elements of an array to 0 ... but only the first one:I have programmed little in the last while so I wil...
We are trying to develop a device that uses SPI communication (Receive Only Master).Are there any sample programs for SPI communication (Receive Only Master)?Which should be executed first: "Receive Only Master HAL_SPI_Receive" or "Transmit Only Slav...
I have some questions. I read that STOP mode has a "RAM retention", so when it wakes up it the whole data is still intact (not cleared).When the RAM retention is off then the data is gone when it goes to STOP mode. So when it Wakes up does it restart...
Dear,Used MCU: STM32H7B0, 100 pins.In the datasheets we had found that TIM3 use the APB1 peripheral clock.In our case is this 120MHz. But when we use the function "HAL_RCC_GetPCLK1Freq()" we become 60MHz.This isn't correct. So what function should we...
