New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

Resolved! Does STM32U5xx HAL documentation exists?

Simple question, I'm trying to locate a user manual for STM32U5xx HAL library but can't find it. The official STM32U5 ST page doesn't provide it. And neither does the STM32CubeU5. Does this mean it doesn't exit yet? But if code is there, then it shou...

Resolved! RMII diagrams

Hi, we are working with a STM32F217 and the RMII bus.In the two documents reported I see an inconsistency on the diagrams (on the one hand rising edge sampling, on the other falling edge). Which one is correct for my chip?RM0033 Figure 328 Reference ...

Resolved! STM32L412xx UFBGA package VBUS pins?

Dear allI'm starting a design with the  STM32L412R8I (or  maybe STM32L412RBI6) and I cannot find the VBUS dedicated pin in the datasheet nor in the manual. In this design the USB will be always device (no OTG)Is it enough to have VDDUSB powered to de...

Resolved! STM32L4A6 ADC Sequence Time less than expected

I'm using ADC1 to measure the Temperature Sensor channel and the Vrefint channel. I expect those to vary very slowly and I am in not in a hurry so I am maximizing the sampling time. These are my settings in STM32CubeIDE:It generates the following in ...

SPI - role of the NSS signal?

This is a question about SPI communication.There is an NSS pin for SPI communication, but is it okay to use GPIO instead of the NSS pin when there is one master and one slave?We don't quite understand the role of NSS. I think it will be useful when t...

STM32U545 : LPBAM cotinuous ADC multichannel

Hi,I am using an STM32U545 on which I expect to use ADC4_IN1 and ADC4_IN18 in stop mode 2 (using LPBAM).I want to create two buffer (buff1 and buff2 uint16_t[32]) dedicated to each input.I want to read 32 samples from input1 then 32 samples from inpu...
