PIC18F2455 PIC-Tengu CCS C Talking Robot

Funny robot application is a fun app 🙂 Speaking software installed on PIC18F2455 with CCS C prepared according to the audio signal around talking smiley made ​​of LEDs. Also working in windows environment with source code in JAVA based program’s

When I first saw the cloned Tengu developed by Alex on the Hackaday blog, I thought it was a suitable project to learn to use certain functions of PIC microcontrollers such as A/D converters, interrupts and timers.

After examining the features of the original Tengu developed by Crispin Jones, I started to determine the requirements for my own clone.

I decided to add a simple game that aims to turn it into a personalized birthday present; my sister’s birthday was near.

It is very easy to use. After connecting the PIC-Tengu to a USB port, it will boot in sleep state. He will wake up by blowing on his face. Then the PIC-Tengu yawns and starts the candle game if and only if we are using it for the first time.

The object of this game is to blow out the candles one by one, so it can be pretty boring if the honoree is over a certain age, but less painful than pulling their ears. Fortunately, my sister is only 25 years old.

A personalized ticker appears when the game is over.

Later, PIC-Tengu begins to imitate every sound it hears. Four sets of faces are available: eagle-nosed, snub-nosed, noseless, and Luciano. The active face set changes with a blowing or strong sound. Pic-Tengu audio sensitivity is configurable via the rear potentiometer.

Pressing this button toggles between imitation mode and tickertape mode. If we hold down the button for more than 2 seconds, the PIC-Tengu will reset and return to the same state as if it was never used before; this means the candle games will reappear after you wake him up.

Finally, if there is no activity for more than 5 minutes in emulation mode, the PIC-Tengu will go to sleep. The brains of this project is a PIC18F2455 whose pins directly activate the matrix rows of the LED. There is only one column of LEDs active at any given time, which is determined by pins PIC18F2455, but this time using an intermediary ULN2803.

The signal captured by the microphone is amplified using an LM358 before reaching an analog input at the PIC. The firmware is written in CCS C and written using the parallel port version of PIC, GTP Lite and WinPIC800.

It also has a JAVA-based program that works in the windows environment with its source codes.
