STM32 Project – Digital Photoframe

This is our first advanced project using a powerful 32bit MCU and all sort of modern technologies like Colour QVGA display, Micro SD Card and Embedded file system. We have made several project using 8 bit PICs and AVRs but those were simple and didn’t use modern displays. In today’s world every one owns several gadgets like cell-phone, tablets, media players, hand held gaming device, digital cameras that uses TFT LCDs and uSD storage. So I thought current DIYers should be dreaming of using them in their own design too. This created the need for a DIY project that should help experimenters use such technologies. So I designed a simple ARM project called the "STM32 Digital Photo Frame". Project Description You need to place some BMP format images in the folder "slideshow" in the root of MicroSD card. After that install this MicroSD card in the card slot. Then power up the board using a USB Port. The images will be shown on the QVGA TFT Screen one by one. Their will be an approximate delay of 2 seconds between display of each image. Once all the images have been displayed, the sequence will restart from the first image. The slideshow will continue until the power is removed. Note: In the current version, the BMP file must be 24 bits […]

MicroSD Module

Hi, Last evening I hand soldered a SMD MicroSD Module PCB. The MicroSD Module enable easy connection of MicroSD cards to 5v Microcontrollers. It has on board 3.3v LDO Regulator, 5v to 3.3v i/o converter chip, Indicator LEDs (Power and Activity), SD Pullup resistors, Inductor for clean Hot-swap, Filter capacitor etc. The board is built on hight quality double layer FR4 board.
