I want to setup an system with 4.3" 480x272 LCD Working with LTDC with external flash (External Flash Loader)Can we directly interface an existing QSPI Loader if yes, Then Which one.
STM32F303CBT6 DAC and PA4/PA5
I read a lot about it for other STM32 MCUs but can't find any confirmation that it’s not possible to use PA4 and PA5 as GPIO output and DAC1 channel 1 and channel 2 internally for STM32F303CBT6. There's a hint in the errata of another STM32F303* usin...
Resolved! How to reduce I2C frequency from 100Khz to 20KHz
Hi, i am using STM32F401RE Nucleo board and i want am using I2C channel in standard mode which is upto 100KHz but i due to little long length of communication cable, i want my I2C frequency to be around 20KHz. I am using HSI only as clock source.This...
USB GPIO Alternate function
Posted on March 26, 2013 at 01:59I am using STM32L152 evaluation board. I realized that the USB HID module does not configure the USB D+ D- line as GPIO Alternate function. I wonder that what is the usage of GPIO Alternate function for USB?
Resolved! Standalone MCU Application - Unable to Flash F103
Hey, I am currently trying to get my own hardware to run on STM32 Microcontrollers. In this case, I am using a F103RET6, LQFP64 package. It is being used with very improvised hardware, as a proof of concept only. The layout looks like so, made in Kic...
