Hi I've been searching for some info about these two MCUs and I need some clarifications.1. What is the difference between STM32U585RIT6 and STM32U585RIT6Q?2. On page 150 of DS13086, STM32U585xx datasheet, regarding power supply scheme, I can see the...
Currently i am using USB peripheral for communication (CDC) with STM32F070CBT6 microcontroller. For generating 48MHz clock, i am using internal oscillator as a source for internal PLL circuit. I have to send certain data to STM32 (for save it to exte...
Hi, I am trying to use DMA in my project for SPI and noticed there are 2 type definitions as below:- SPI_HandleTypeDef hspi1; DMA_HandleTypeDef hdma_spi1_tx; Which one do I need to use for SPI transmission as I am having problems using 'hspi1' as b...
Hi, Has anyone fed the Analog Watchdog Internal Signal output into Timer 1 on the STM32G031K6 ? To Drive Mosfet power switches of a Power Supply, The Analog Watchdog is used to limit the current. The timer 1 also has a break function and some fancy f...
Hiwhen the STM32F103 enter the standby mode, it has the lowest power consumption. And it said the voltage regulator is switched off. And all of the data in the RAM will be lost except the backup ram and register of the RTC.But I tested it, the data w...
Hı everyone, ı was trying to design basic timer project in register level about toggling on related led pin every 1 second. However, the led is on a few seconds after that it is off and never becoming on. When ı do the same project in HAL library, it...
Hi,I am working on a new product. For this I use the STM32H723 µC and the LAN8742Ai PHY from Microchip.Our schematics looks like this:We have a 25 MHz crystal connected to the STM32H723 (HSE). The MCO is configured to HSE. The crystal matches the clo...
I'm using STPM-3PHISOSD for testing with Sigma Delta ADC, but I can't understand the relationship between Oversampling of 800 and right bit shift of 6 in the default GUI. I looked up a lot of STM related materials, but none of them explained. In addi...
When I start my program from the uVision debugger the code runs to a debug instruction in the start-up code.It requires three run push buttons to get it past the debug instruction. The program then works perfectly.This problem only happens when I inc...
