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...
Dear all, I am working on FDCAN with Nucleo STM32G474RE. And I cannot receive any messages...Unfortunately I cannot find any examples for this board.I am able to send messages from the board and receive it on PCAN tool.Unfortunately when I send messa...
I'm using DISCO Board STM32F769I and use SDRAM in my application applicationi note that when i write data more than 1023Byte the data is written in the next bytes as expected and also over write from the start of SDRAM (0xC0000000)if there is any con...
This post: https://community.intel.com/t5/Intel-Makers/Low-Voltage-Signaling-SD-Cards/td-p/490563 seems to imply that newer SD cards can operate directly at 1.8V with no translation to 3.3V. Can anyone confirm if STM32H743 supports this?If so, does t...
Hi,I am using STM32G474 with TIM1, TIM8 and TIM20 and working with STM32CubeIDE.I want to updatethe ARR, CCR1, CCR2 and CCR3 regs at the same time. I taught that with the preload register it can be done but it doesn't work for me.So how can I do to s...
Hi All,I am having trouble with DMA transfers using a F429.I am using DMA1, Channel2, Stream6 - regulated by TIM4 Updates.It is a memory to perpheral, 32 bit, single transfer, double buffer Off - from Flash (AHB3) to GPIOG (AHB1).However, it breaks o...
Hello i want to to generate variable phase shifting PWM
I am running an STM32L476RG at 1.8V and have noticed that I2C-3 does not generate a clock or data signal. I have tried isolating the MCU from the rest of the circuit and found that there is still no signal at the MCU pins, so i know the circuit is no...
Hi,I'm trying to use QSPI to interface with a flash memory chip (GD25Q16). I can read and write to memory and status registers using blocking code, but I'd like to use DMA to decrease the CPU load. However, the QSPI handle's State gets stuck in HAL_Q...
I'm using STM32CubeIDE/MX to program and debug a simple demonstration of UART on the B-L475E-IOT01A development board (with integrated STM32L475VG). The code is straightforward (and autogenerated, apart from the hello world message).Probing the pins ...
