I'm reading RM0492 Rev 3 about I2C's controller transmitter. The original words on the page of 1185 areWhen RELOAD = 0 and the number of data bytes defined in NBYTES[7:0] is transferred: • In automatic end mode (AUTOEND = 1), a STOP condition is auto...
Hello, In the MCU datasheet, there is a table on page 200: Table 72. Typical dynamic current consumption of peripherals.What is the meaning of the current writing in the peripherals on stop modes, since in this mode, all clocks in the core domain are...
Hello,I am using STM32H750VBT6 to perform microSD card write operations. After a number of writes, the CPU sometimes resets during a write operation. At the same time, the Vcore (1.13V) rail shows a voltage drop. The issue is random, but the higher t...
Dear STM32 users and developers, This new thread is back and is dedicated for our technical developers community to share last STM32 updates, the first part will be products documentation news such as datasheets, Erratas, Applications notes followed...
Hello everyone,I’m working on a control unit board based on the STM32F407VETx (LQFP100) microcontroller. During development I noticed that some pins configured as external interrupts (rising edge) were being triggered more often than expected.To bett...
A new question moved from this thread. In many examples they use the Vref int for the calculation of the temperature. Do I need it for the C0 also or can it be done without?
Hi STM32 community.I'm working on an embedded system which uses a RK3399 CPU (running Linux, functions as a USB host) and a STM32F302CC (Runing FreeRTOS, functions as a USB device). This runs on a custom motherboard. They communicate with each other ...
Hello everyone,I am currently working on a project using the STM32H755 microcontroller, and I am facing an issue with the program getting stuck in the `Reset_Handler` during debugging. Specifically, the code halts at the instruction `ldr sp, =_estack...
Hi, I'm stuck on a problem with setting PWR_CR_VOS on NUCLEO-32 STM32L031K6- I want to select HSI16-PLL as clock source- VDD is 3.3V- FLASH latency is set to 1WSBut I can only set PWR_CR_VOS to RANGE 2 and RANGE 3.RANGE 1 cannot be selected, so I can...
HI, how do I read the temperature value of a STM32C071 ADC and convert it into °C using DMA? I cant find any formula in the datasheet. BR Matthias
