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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello,e.g. in RM00367 Rev 8 released some days ago, the block diagram of the LPTIM block in 24.4.1 does not show LPTIM_ETR pin/functionality.
Hi, I'm using the STM32G070 processor. As power supply a TPS563201 regulator. Is a LDO pos regulator necessary? or just the switching regulator is enough? Is the processor stability or durability reduced due to switching regulator? (I am not using pr...
I'm trying to transmit some data using DMA as a slave SPI device. I'm sending 8 byte but the peripheral always gives me 9 byte on the MISO line (first byte twice). The Master NSS is connected to a GPIO input (SPI_ENABLE) using external interrupt Mode...
I've managed to get the DFSDM working with a PDM microphone (on a STM32L496 board) - using direct access to registers. But the documentation often made things more difficult than they needed to be. Just a few extra sentences, less ambiguous language ...
Hello,I wanted to experience data transmission through NB-IoT in Canada by using a Cellular Discovery Kit (B-L462E-CELL1).The eSIM is activated and the board communicates with echoclient, but it selects the operator automatically. Unfortunately, the ...
As shown in above figure.The EXT/GPIO pin directly connected to MCU with pull up resistor (10K).So once the switch press the PMOSFET start switching supply to MCU.Please let me know the effect of voltage on EXT/GPIO pin without suppling power to MCU.
Hello.Hi Forum. I am new to the H743 line of processors and the first thing I tried is getting printf() output on the traceswo pin of my nucleo-H743ZI. What I have tried:1. The 'Everything out of the box' way:Use cubeMX to configure sys to async trac...
Hi everyone!I've got something strange with my ADCs (working on STM32H743). Everything was working until I realized that both of my ADC values are refreshed only if use other DMA peripheral. For example, it seems that sending SPI refresh the ADC, oth...
