Schaer+ Programmer using PIC12F629 microcontroller

Description Schaer is a generic programmer circuit capable of uploading and downloading firmware to/from several electronic devices like microcontrollers and eeproms. This and other programmers came to my attention when I was working in CAMBADA, the robotic soccer team from the University of Aveiro, and since all other programmers available there were too expensive for me to buy

Air diplay adapted schematic

A modified version of the “Air diplay” adapted to be used in a bicycle using PIC12F629 microcontroller

Anthony from Cumaná, Venezuela, made his own “Persistence of vision” (POV) display, similar to my Air Display but it can be mounted on any bicycle wheels and it displays fifteen messages in Spanish. Here is the PCB with each part of the project. It uses a 12F629, works with a voltage of 3Volts This is

Using Fixed Voltage Reference FVR for A D conversion in enhanced mid range PIC microcontrollers

Using Fixed Voltage Reference (FVR) for A/D conversion in enhanced mid-range PIC microcontrollers

The reference voltage plays a very important role in any A/D conversion. It determines both the range and the resolution (Volt/Count) of the A/D conversion. Besides, the accuracy of the conversion also depends upon how stable the reference voltage is. Usually in PIC microcontrollers, the reference voltage for A/D conversion can be selected as the
