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...
Hi,I am using backup sram in stm32f429zi. Data Read write in backup sram section is executing properly and data will retain after power down. But when we do the power UP then my program is not executing from main loop. so my code is not working as re...
If I am doing software trigger single conversion of 3 a/d channels and I set my end of conversion selection to be 'End of Single conversion' (CubeMX): Can I expect my to enter my ISR A/D callback at EACH EOCIF?All indications are that if I read the A...
I'm trying to transmit messages through CAN using HAL library. For test I repeated code from the first part of this video I have the same bluepill so I just did the same. Also I've tried his project, but changing Nucleo RE to ZE model. I've looked th...
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.
