PMIC25 Configuring Method in DK Board from mST

Hi all, I’m searching a method to configure the NVRAM STPMIC25 VINOK_rise param in the 0x90 adress Register (NVM_MAIN_CTRL_ SHR1) As this is a sensitive reg I’m supposing this field and may others are Locked in the NRAM in the DK board from ST. Pleas

STM32L4, voltage breakdown on high-impedance ADC input after MX_ADCx_Init

Hello everyone,I measure a voltage on a STM32L496 using the internal ADC and found the following issue:Setup:The voltage is scaled down via a high-impedance voltage divider (2 x 470kOhm). To avoid distortion by sampling, the voltage divider has a 100

NUCLEO-H755ZI-Q: "No STM32 target found" error via ST-LINK/V3 (STM32CubeProgrammer)

Hey everyone,I'm having a rough time getting my NUCLEO-H755ZI-Q board to talk to my PC. Whenever I try to connect using STM32CubeProgrammer or debug from STM32CubeIDE, I keep hitting the same error: Error: No STM32 target found!I'm using the onboard

STM32N657: absolute maximum ratings for VDDSMPS and VDDA18PMU (not in DS14791 Table 22)

STM32 MCUs Products

Hello,We are designing a PCB around the STM32N657B0 (VFBGA198) using the internal SMPS. VDDSMPS and VDDA18PMU are fed from a dedicated 1.8 V buck, with VDDA18PMU filtered from the same rail, as per Figure 2 in DS14791.For our derating and fault analy

STM32 MCUs Wireless

Hi all,I'm designing a LoRa node with STM32WL55JCU6 (UFBGA73), using RFO_LP only (+14 dBm, high band 868 MHz). My starting point is the MB1842 reference design, which uses a BGS12SN6 RF switch between the TX and RX paths.For UFQFPN48, ST provides dir

Using PWM to control LED brightness on an STM32

I'm looking into the best way to control the brightness of an LED load using PWM from an STM32 and would appreciate some advice on the practical side of the implementation.My understanding is that the average brightness can be controlled by changing

Using the Cortex-M0+ as a load core, free GPIOs and the cycle counter on the Cortex-M33, and a common FreeRTOS/Zephyr workflow

Hello,I am a Master's student comparing FreeRTOS and Zephyr on the Cortex-M33 of the STM32MP257F-DK, with Linux running on the Cortex-A35. I measure task timing on the M33 with the DWT cycle counter and an oscilloscope, and I want a second core runni
