Which PIC Microcontroller to Choose?

The Microchip PIC microcontroller range looks really daunting at first, with lots of 8, 16 and 32 bit devices to choose from. This article will look at 8-bit PICs as they are adequate for most purposes and far more suited to beginners.

There are different series of 8-bit PIC microcontrollers- PIC10F, PIC12F, PIC16F and PIC18F, all with different features and price bands. The PIC10F and PIC12F are the cheapest and generally have less memory, smaller pin counts and less peripherals.

AVRStudio Explored

AVRStudio is the development software for AVR microcontrollers supplied by Atmel to allow users to easily develop code for their devices. It includes project management, code editors, assembler and C compilers, simulator and programmer and emulator support. It has been developed over the years and has reached AtmelStudio v7.2 but older versions are available, so which version is the best for you?

Using the AVR Xmega Microcontroller Family

Atmel have added the Xmega series to their AVR range and we are seeing more interest in these microcontrollers as time goes by, but who should be looking at using them?

Well for a start, it is not a chip for complete beginners and people wanting to learn microcontrollers from scratch would be better off starting with standard AVR ATmega microcontroller kits or PIC Microcontroller Kits.

Using USART or UART on a Microcontroller

First, what is the difference between these terms, UART and USART? UART stands for Universal Asynchronous Receiver and Transmitter, and USART means Universal Synchronous and Asynchronous Receiver and Transmitter. Most microcontrollers today, like PIC and AVR, have USART, but the Synchronous function is not often used as they have other synchronous devices like I2C and SPI. So this post will concentrate on asynchronous transmission, which is the same on both devices.

Resurrecting Voloci Electric Motorbike

The Voloci electric motorbike was made and sold by Nova Cruz Products Inc. during the period 2001-2003. It was too far ahead of its time and production soon ceased, but there are quite a lot of them out there. Unfortunately, the firmware had a bug and could get corrupted and a lot of these bikes did not get the very last update that fixed this. Kanda have just been working with one such guy to help him resurrect his machine.
