Electronics spare parts market @ Bangalore

Where is it located :

On S.P. Road, near Corporation circle. There are many small lanes opening up from SP Road. These are filled with electronics spares shops, computer shops and mobile shops.

Closed :  All electronics spares shops are closed on Sunday. Select few computer shops will be open.

USBasp Drivers for Windows 7

I have uploaded USBasp drivers for windows 7 on megaupload. Drivers can be downloaded from the following link:

Instructions:

AVR fuse bits settings

Setting AVR fuse bits correctly is most important and equally confusing part for many beginners. In this post I have presented some of the ready to use fuse bit settings and corresponding batch files, which can be used with AVRdude.

Link for downloading avrdude batch files (to be used with USBasp) is given at the end of this post.

Xilinx ChipScope Tutorial

Using the ChipScope Pro for Testing HDL Designs on FPGAs

Introduction:

Simulation based method is widely used for debugging the FPGA design on computers. Time required for simulating complex design for all possible test cases becomes prohibitively large and simulation approach fails. For rapid testing, such designs can be loaded on to the target FPGAs and tested by applying test inputs and directly observing their outputs. As the complexity of the design under test increases, so does the impracticality of attaching test equipment probes to these devices under test. The ChipScope Pro tools integrate key logic analyzer and other test and measurement hardware components with the target design inside the FPGA. Computer based software tool communicate with these hardware components and provide a designer robust logic analyzer solution.

In this tutorial we will use simple UP counter design and test it using ChipScope.

EAGLE Library – List of most commonly used electronics components

12 Nov 2009 – Post Updated

EAGLE is preferred by many hobbyists and professionals all over the world. EAGLE comes with huge component library, however to find the desired part in this library is really difficult for beginners. Generally we need resistors, capacitors, voltage regulators, pin headers, connectors, etc when designing any electronic PCB. Following is the list of EAGLE library part names of most commonly used electronics components. This list will be very handy when you have just started using the EAGLE and don’t know which part to select and from which library.

CodeVisionAVR Tip: How to display formatted numbers on LCD

Generally at some point of time we all need to display something more than “hello world” onto LCD. CodeVisionAVR(cvavr) provides functions like lcd_putsf() and lcd_puts() for displaying strings on LCD. However these function cannot be used directly to display something like : “Vin = 10V” or may be “Value = 0000A01F”. In short these functions do not provide the functionality of formatted output, as provided by printf() function. How to implement this functionality is objective of this post. Fortunately there is very simple way to get this thing done …

Alert: Using RealView MDK 3.22 ? Switch to latest version

I recently started working on ARM controllers. I have been using RealView MDK 3.22. However I noticed that, when I was trying to run my simple program involving UART peripheral, it was getting compiled but was not running when downloaded on uC.

The same program started working when I downloaded MDK 3.7. So if your programs are driving you nuts because of some strange reasons, which you are not able to figure out, then update to latest version.

Informative and Nice FPGA Tutorial for beginners

I stumbled upon following FPGA Tutorial while surfing the web. It is great for beginners, who don’t know what FPGAs are. This Tutorial covers basic concepts of PLDs,CPLDs and FPGAs. It then gives overview of internal architecture of FPGA. Tutorial also gives overview about design considerations, use of Xilinx tools. In short it covers all basics of FPGAs based design flow using Xilinx FPGAs and software tools.
