Recently, I tested the 0832 LED Matrix Board that I purchased from Sure Electronics. Since I have a simple AVR microcontroller breakout board and a PIR sensor that senses motion, I decided to make something fun using the 0832 LED Matrix Board. [Read more...]
The LPC1343 is a low power ARM Cortex M3 microcontroller targeted for embedded applications. It has 32KB of flash memory and 8KB of SRAM. On-chip peripherals include I2c, SPI, UART, Timers, Interrupts, ADC, USB, etc. It includes both UART and USB bootloader. Believe me, the USB bootloader is cool. [Read more...]
Few weeks ago, I purchased a 32×8 LED matrix board from Sure Electronics. It was a very nice board and I was really excited to use it in one of my projects.
This board is composed of four 8×8 LED matrix modules and HT1632 LED matrix driver. It can be powered by a 5VDC supply and at least three microcontroller pins are needed to control the board.
I tested the board using my 28-pin AVR breakout board and ATmega8 microcontroller. It was not very complicated to use but, to make things easier, I am planning to write my own library for this board.
Here’s the video of the test.
Hey, take a look also at my project about 8×8 LED matrix board using an AVR microcontroller.
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...]
