• ATMEL Microcontroller
• ARM Microcontroller
• Microcontroller Kit Vendors
• Microcontroller versus Microprocessor

There are various ways one can do microcontroller programming, popularly C and assembly language is used. After the program is written for specific tasks either in C or assembly language, the same need to be converted to hexadecimal file will be burnt on microcontroller's internal ROM if the program is small or on external program memory if the program is large.

Programming devices

Microcontroller programmer, flash programmer or EPROM programmer are used for programming the device. Various such kits are available from the microcontroller device manufacturers themselves.

C Language Microcontroller programming Example

Following Microcontroller hardware circuit show interfacing of LED with port 1/pin no. 1. We will write C program to switch ON and OFF LED at some regular interval using delay routine.

microcontroller interface led As shown in the program above delay_1ms function introduces delay of about 1 ms which can be called in for loop to generate delay of your choice. hence delay_ms passed with argument 10 introduces 10ms of delay. P1^1=1 switches OFF LED and P1^1=0 switches ON LED. This instructions are put in while loop hence will continuously run till microcontroller circuit is powered ON. The example program also explains how to configure serial port to be used for interfacing external device to be used for serial communication at some baud rate.
