NUCLEO-U575 CAPTURE FAIL, is it a silicon level bug?

2024-10-08
For the Nucleo-575ZI-Q, while in stop mode 2, I have the capture module enabled, I set CH1 IO Usage as input.A square wave generator connected to PC1->LPTIM_CH1.While the Micro is in stop mode 2 an indeterminate number of pulses trigger successive ca...

STM32U LPTIM Autonomous Mode

2024-10-04
I am using the LPTIM3 with LSEAn external input is used to trigger a capture.The STM32U575  spends most of the time in STOP MODE 2.To keep the LSE active in the LPTIM use the following instruction:_HAL_RCC_LPTIM3_CLKAM_ENABLE(); // SET_BIT(RCC->SRDAM...

Can the STM32U5 converge to an efficient algorithm, or a few, to enter to low power?

2024-05-05
At first this post looks more like a catharsis than a question, but ultimately there is a question.Why are there as many procedures to enter sleep mode as there are STM32 programmers? There I see Piranha posting his own catharsis, titled "The ST Stan...

STLINK-V3MINIE current draw

2024-05-02
I am using a STLINK-V3MINIE  as a programmer with my custom board.The custom board has a battery holder, with 2xAA 1.5V each.A jumper is in series with the positive terminal of the battery holder, where I am using an ammeter.I measure a baseline of 3...

SystemClock_Config Visivility

2024-05-01
The image below shows how Cube MX allows us to control the visibility of some functions.Uncheking a prototype moves it from main.c (private) to main.h (public). When unchecking for SystemClock_Config, its  prototype is still generated on main.c, only...
