| Beginner's Guide to Embedding C Programming Vol 3 |
In his “Beginner’s Guide to Embedded C” and
“Beginner’s Guide to Embedded C – Volume 2” books Chuck Hellebuyck took the
reader through the very beginning of learning how to program embedded microcontrollers
in the C language using a Microchip PIC microcontroller and the Microchip
HI-TECH C compiler.
In “Beginner’s Guide to Embedded C Programming – Volume 3” Chuck Hellebuyck
takes another leap forward by showing you the steps to create the SimpleC
library of functions that make programming in C even easier. This approach
shows the reader how they can create their own functions and expand the SimpleC
library to make creating microcontroller projects much quicker than writing
in raw C code. This book will clearly be the reference for future programmers
who want to build electronic gadgets without all the painstaking steps of
writing every C statement while producing a working project in less time
and with less effort.
The SimpleC library will make the following functions as easy as one command
line:
• Controlling Digital Outputs
• Reading Digital Inputs
• Monitoring Analog Voltages
• Driving Liquid Crystal Display Modules
• Driving Digital PWM Signals
• Sending/Receiving via SPI and I2C Communication
• Writing to/Reading from External EEPROM
• Writing to/Reading from External I/O Expanders
• And More!
The book uses the open source PIC16F886 based CHIPINO module for the hardware
and also forms the platform to make future electronic projects and gadgets
easier to build.
