STM32L412 "Reference voltage buffered output" feature

Hello,DS12469 Rev 6 in Features on page 1 lists "Accurate 2.5 V or 2.048 V reference voltage buffered output" under  "Rich analog peripherals". However "Table 2. STM32L412xx family device features and peripheral counts (continued)" says "Internal vol...

How to make partition binaries for STM32F103ZC using Makefiles

I just switched from Arduino to the ST HAL library, I'm quite new to both the structure and makefiles in general. I'm using a chip that allows for multiple parts that can be used for OTA's for example. While I have made a working project that can upl...

two kinds of deadtime config

yes ， above fig about two kinds of config deadtime ,I don't know how to get that waveformI have readed RM about deadtime chapter,but I still not clear

How to implement MQTT with STM32L4 on ESP8266?

ESP8266 is communicating serially with STM32L4 through AT commands.Now I would like to implement the MQTT protocol implementation on this?

Why SDADC could't not start

Hi everyone,I designed my custom board with stm32f373c8. SDADC runs properly when voltage reference is setted with Vref or VDDA. But when voltage reference is setted with internal 1.8 volt or internal 1.2 , sdadc could't start. It waited while loop t...

Is it normal if MCU of NUCLEOH743 gets hot at 400/480Mhz and ~120mA current at IDD Jumper?

I am using latest CubeMx and CubeH7 versionsWith the increase in clock the MCU start getting hot especially at 400 or 480Mhz. So Is it a normal?I have also checked the current consumption at IDD jumper and it is ~120mA. Iis this normal value when no ...

How to test STM32F469AI of packaging type WLCSP168 if its receiving power?

Hi everyone,I have the STEVAL-IDP005V1 sensor board on which STM32F469AI MCU is present. I suspect that something is wrong with the D9 pin of MCU which is supposed to receive 3.3V from the power management unit on the board which I tested to be up an...

STM32F042 CAN POLLING WORKS - INTERRUPTS NOT HAPPENING

I have coded it both ways, so the hardware and software works except when switching to interrupt-driven receive. No interrupts happen, though I have checked and rechecked. The global NVIC can interrupt setting is there, and the enable. The CAN priori...

ADC single vs continuous mode. If the ADC is set in single conversion mode will a repetitive pin read initiate another conversion at each read or will the same data be read each time after the first read?

CAN Bit Stuff Error during CAN2 pins initialization

Hi,I am using STM32F103RFT6 64 pin package mcu. i am seeing can bit stuff error during CAN2 TX pin ( PB9) initialization. when mcu is in reset state this pin is in high state, the moment CANTX pin gets configure to Alternate function pushpul, Low s...
