STM32L051C8 comparator consumption

Hi,I have a strange problem on an STM32L051C8 with the comparators enabled in window mode.If I put the system in stop about 20 seconds after powering the microcontroller, the current draw is about 250 uA. If I then exit the stop mode with a soft rese...

I2C with repeated start.

I have seen the question asked many times, references made but the question never gets answered with precision.  So, once again...I want to use HAL_I2C_Master_Seq_Transmit_IT along with receive to read an I2C device register.1. START SLAVEADDRESSWR (...

peripherals power consumption of stm32u585 in stop mode

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...

Resolved! HAL_ADC_Start_DMA caused main loop to become blocked?

Hi, I am configuring the ADC in single-channel continuous conversion mode using DMA. However, once I call HAL_ADC_Start_DMA(&hadc, &AD_RES, 1), the main loop stops executing, and the HAL_ADC_ConvCpltCallback() function is not triggered.I noticed that...

Resolved! OCTOSPI signal integrity issue on STM32H723 vs STM32H725

Hello everyone,This is my first post on the ST Community forum.I recently moved from a custom 6-layer board using STM32H725IGKB to a simpler 4-layer board using STM32H723ZGT6. Both designs use an external OCTOSPI memory, with 50 ohm controlled-impeda...
