Measure STM32F373 core temperature
Hi,I was measuring the STM32F373 core temperature.It seems that the core is 56°C while the environment is 23°C, no housing.Is the 56°C a reasonable temperature? It looks quite high to me.I used the settings below:

Resolved! Mixing HAL and Direct Register Manipulation
Hello. I am writing a code to read ADC data from an AC voltage sensor. I used HAL to initialize ADC 1 and USART2 for checking the values in Putty. However, I would like to use direct register manipulation to send data to USART6 so that it can transmi...
Resolved! Sleep mode, GPIOs and RCC_AHB2LPENR - STM32H5, EXTI wakeup sources
HelloWhat will happen with the IOs when MCU is put to Sleep mode (one of power modes in PWR) and register bits in RCC_AHB2LPENR for each GPIO-block are reset? When bits are reset, the peripheral clock is disabled during Sleep mode.Can the IOs still b...
Which MCU is better for Timer?
Hello.I need Timer for send high speed data.To send data, i need at least 115200 fps.Can you recommend which MCU is perfect for me?
How to use half precision floating variable
Posted on May 22, 2017 at 12:26Hello,I would like to use half precision floating variable in my project but i don't know how. I'm working on a NUCLEO-L073 board that embeds a cortex m0 STM32l073 MCU that does not have any FPU. I'm using the SW4STM32...
How to get ADC-DMA working on a STM32G431KB board with CubeIDE
Hi, I am using a STM32G431KB board with STMCubeIDE. I am trying to read out the one ADC using DMA but have run into problems. As I am new to the STM32G4 and STM STMCubeIDE. I decided to follow the example of Shawn Hymel https://www.youtube.com/watch?...
How to use Vrefint when Vref+ is tied to Vssa?
Hi,I wanted to use STM32H743 with TFBGA100 package in a new project. Unfortunately this package does not provide Vref+ pin and it is internally tied to Vssa. I don't understand what is the reference source for ADCs and DAC, can I use VREFBUF in hold ...
Resolved! STM32H7B3LIHQ and MX25LM51245GXDI00 OctoSPI flash problem.
Hi.I am using STM32H7B3LIHQ MCU, MX25LM51245GXDI00 OSPI flash, IS42S32800J-6BLI SDRAM and 24bit TFT screen. I used the schematic of the STM32H7B3I-EVAL (MB1331) board when creating the scheme. I wrote programs for FMC, OctoSPI and LTDC peripherals us...
Resolved! Can a large number of different interrupts of the same priority on the STM32F4 cause problems?
I am experiencing processor freezes at certain points of use in our products using STM32F4.I am analyzing the cause and have a question regarding this.The processor I am using is STM32F469NI. There is a specific operation that it freezes at, and when...
Resolved! STM32L4 Vbat ADC measurement incorrect
I'm using Vbat as a battery voltage monitor on an STM32L431. Vref is the VDDA pin on this part, which is 3.3V. In my test case, Vbat is also connected to the same 3.3V.Vbat reads a raw count of around 1044. The internal divider is /3, so this come...
