Core supply for STM32H573AII3Q
Hello, We are using STM32H573AII3Q in our application. It has in-built SMPS for core power supply. Just wanted to know can we disable this SMPS and use seperate external 1V LDO to power the core?

Resolved! VREF Internal voltage reference G431 series
Hello,Can anyone suggest whether or not I need to connect external capacitors to the VREF+ pin if I plan to use VREF only for the onboard DAC?Could this be a hardware problem?STM32G431CBT6. The problem is that on the oscillogram I see oscillations wi...
Setup PWM on TIM12 for trailing edge or leading edge
Dear all,I have a custom pcb with a STM32H753 on it.There I'm already using the TIM12 function for generating a PWM output signal This is my init function - generated from CubeMX: void MX_TIM12_Init(void) { /* USER CODE BEGIN TIM12_Init 0 */ /...
Download elf to STM32H743 failed when code over 512K , STM32CubeIDE 1.16.0
I use STM32CubeIDE 1.16.0 to do project and use STM32H743.when my code is over 512K, I re-write ld file,but download is failed.But I use STM32CubeProgrammer to download the same elf file,it worked!!! So what's wrong about it ?
Resolved! What is the correct connection for VCAP1 and VCAP2?
Hello,VCAP1 and VCAP2 are external capacitors for the core's voltage regulator.The data sheet for the STM32F479VI states that, "Stabilization for the main regulator is achieved by connecting an external capacitor CEXT to the VCAP1/VCAP2 pins."I inter...
W25Q80DV QSPI with STM32F412VET3 - Strange things I don't understand.
Hi everyone.So I have W25Q80DV QSPI with STM32F412VET, I would like to use it to store some data. As per datasheet for W25Q80DV its flash is 8mbit and so I have the following initialization code : hqspi.Instance = QUADSPI;hqspi.Init.ClockPrescaler = ...
Resolved! Do I need to connect VSSDSI when not using the display blocks?
Hello,I'm using a STM32F479VI but I do not need the DSI (display) functionality for my current application.It seems that block runs on a independent power supply derived from VDD.Can I leave the DSI power pins floating or should I power them anyway?
Resolved! Why are DSI pins green when DSI is disabled, they say RESET_STATE.
Hello, This is how an STM32F479VI appears in CubeIDE without doing any configuration.DSI is actually disabled, but the pin are light green and set RESET_STATE when I hoover over them.What is CubeIDE trying to tell me?I do not want to use DSI in this ...
