Embedded Linux

            Yes I am diving little into traditional stuff, still its interesting to try something from scratch. While working on some hi-tech stuff where we mostly don't care about writing something from scratch as its time consuming. Now a days platforms like arduino are concentrating on Application, they are not meant to use to understand the hardware peripheral. In fact I never tried it though ;). I know there are lots of example available online regarding this graphics LCD. This LCD I selected is HDG128x64F, which is more or less what is conventionally used, but I found some differences as in column addressing method. I got datasheet about HDG128x64F here , where I can only find some commands which are more or less similar to that of 16x2 LCD except RAM addressing method. To start working on this I preferred using Proteus Simulation software to make it more flexible in terms of Hardware. Note - This software I tried with Proteus not on actual h...

       As many people need some sort of storage in their embedded project, they prefer to use SPI flash. Hence I decided to try this interfacing with ATMEGA32 microcontroller. This SPI flash is 16Mb flash, works on SPI interface. You can reuse below code if you want to integrate this flash to your project. I tested this code using proteus simulation, you can also test and comment. Features of M45PE16- 16Mb of page-erasable Flash memory Page size: 256 bytes Sector erase: 512Kb 75 MHz clock frequency (MAX) In current interfacing I only did Page Write/ Read API's. The SPI needs to configure in Mode 0, and Master at Microcontroller side as given in code below. The result or Page read bytes are displayed over terminal using UART. Code- M45PE16.c /*  *  *  *  Created on: Apr 18, 2014  *      Author: Shrenik Shikhare  *      File: M45PE16.c  *      Discription: Interfaci...
