## What is AVR Tutorial Pro?

This app is a AVR tutorial based on ATMEGA16 C language. It is suitable for hobbyist or engineering students.


Learning AVR mcu is difficult. The learning curve is steep. The process including reading datasheet, writing code, building prototypes and troubleshooting. The most possible errors are the setting wrong value of registers.

Now, AVR tutorial Pro is the solution. The code wizard allow you to set the timer, UART, ADC, interrupt and peripherals by just a few clicks in setting. The proven C source code is generated automatically. 


Though the code wizard is based on ATMEGA16 mcu, it is easy to port to other ATMEGA mcu since the source code is highly structured


Features
• AVR architecture review
• AVR asm mnemonics & C language
• 21 demo projects including LED, buzzer, key switch, lcm16x2, ADC, etc
