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 ...
Hello, my STM32L011's core is running at 32 MHz. I use systick for 1 ms interrupt. However, if i try to use the WFI inside my while loop in my delay function, the timebase changes from 1 ms to 6.28 ms. Any help is appreciated!#include "user_systick.h...
Hey Guys, iam trying to convert Arduino Code to my C Project in CubeIDE..I have some troubles(=warnings and iam unsure) with the SPI Trasmit functions.Could you tell me if my code does the same as the Arduino Code?ARDUINO : ******************* void ...
We are Planning to Use STM32F7508-DK board for our Application. As I go through Datasheet of it. It is mention that 64 KB for internal flash. But I am very sure that my application required more than 64 KB. Question : Can we use QSPI Flash in case ...
