Projects, tutorials, and articles about microcontrollers (AVR, PIC, 8051, MSP430, and STM32 or other ARM architectures), FPGA, analog electronics, and digital electronics
Recently, I unboxed and reviewed the STM32 Discovery kit that I just received. I was very happy with it because it’s very cheap for a 32-bit microcontroller development kit with on-board debugger. I tested it with a small program and it was very easy to use.
However, I needed to tweak the STM32 Discovery a bit. There was no big reason for that. I just wanted my kit to look like how I wanted it to be. [Read more...]
It was almost three years since I wrote my last VHDL program. That was the time when I was still an undergrad student. It was long ago and I almost forgot most of the concepts that i learned about VHDL programming. [Read more...]
Recently, ST Microelectronics launched STM32 Value Line Discovery, one of the cheapest microcontroller development boards available. I did not hesitate to purchase one because it’s priced at more or less 10 USD. When I received the kit, I unboxed it right away. The simplicity of the package really caught my attention and I can’t help but give it a review. [Read more...]
Just a few weeks ago, I availed the PCB order service offered by http://dorkbotpdx.org/. The price is US $2 per square inch of Printed Circuit Board or PCB and you are going to receive three copies of each PCB design. There is no setup fee and that makes the service very cheap. Shipping within US is free (am i right?) but the international shipping is not so cheap if you are going to avail the service for a single small PCB design.
This microcontroller project is another version of a persistence of vision or POV toy. It has 8 LEDs and it is powered by ATtiny2313 (AVR microcontroller by Atmel) operating at 2 x AA batteries. This is a tiny toy and it can be carried easily inside your pockets.
