http://www.waitingforfriday.com/index.php/MicroSimon This project creates a micro-sized MB Electronics Simon game clone using an 8-pin PIC12F683 microcontroller. The original 'game 1' of Simon is re-created including all 4 skill levels. The project was made for the Sparkfun microcontroller competition (2011) and demonstrates several useful design techniques for using low pin-count controllers such as low-power sleep, charlieplexing, random number generation and switch multiplexing using a voltage divider with an ADC. The board is also in-circuit programmable making it easy to change and experiment with the software (which is coded in C and fits in the 2K of available program memory).

http://www.waitingforfriday.com/index.php/USB_Generic_HID_Open_Source_Framework_for_Atmel_AVR_and_Windows Version 4 of the Generic HID library supports the ATmega32U4 and provides both a test and reference hardware and software environment for you to build your own USB projects using Windows and AVR. The code is now covered by the MIT licence allowing both commercial and non-commercial use. Only attribution is required in order to use the framework in your own projects.

http://www.waitingforfriday.com/index.php/USB_RGB_LED_VU_Meter This project creates a RGB LED VU Meter which is controlled via USB by a Windows 7 or Vista host machine. The project serves several purposes: Firstly, it demonstrates how to read audio information from the Windows machine and pass this over USB to the device (which is a question which popped up several times after my USB Performance Monitor project). Secondly, it implements an open source TLC5940 driver. Although a library has been available for the AVR microcontroller, I wasn't able to find an open source library for the PIC. Hopefully this demonstration will be useful to anyone wanting to control a large number of LEDs with PWM brightness control. Originally published on YouTube: 2010-07-19

http://www.waitingforfriday.com/index.php/PIC18F_USART_implementation_with_Go-back-N_ARQ This video shows a demonstration of 2 PIC18F2550s communicating over a USART serial link. The communication stack supports flow-control, error-correction using CRC16 and a Go-Back-N ARQ sliding window mechanism. In the video you can see the Tx and Rx lines interrupted and the DTE and DCE being reset, the LED status indication shows the stack recovery mechanism in action. For more details please see the project page on my website. Originally published on YouTube: 2010-11-05
