If you are looking for USB PIC programmer. Here is a nice PIC programmer designed by ‘keolereaon’ a member on instructables.com .This programmer supports pic10F, 12F, 16C, 16F, 18F, 24Cxx EEPROM. It works with only Winpic800 v.355. This is one of the fastest and also the best method to program the popular series of PIC microcontroller. The programmer includes all the things that are required that is the hex file, winpic800, PCB board in ARES and also the schematic. The schematics as well as the PCB along with the photos was developed by PICMASTERS, based on some valuable work done before
All the files which include the usb driver, layout of the circuit, hardware setting programmer are included in a file which can be found on author article on instructables.com. The good thing about the project is that the project is totally open source and hence every one can contribute to its growth at any point of time.
I believe it sounds a bit unreal, but it may work. To get job is pretty easy, but first you need to make a good impression to your future employer. Sending perfect resume doesn’t guarantee a success, because all your competitors are smart enough to make their own CV look great so there is a little chance that yours will get exceptional attention. There is another way to make you see different. So Ramiro, the guy who is looking for his dream job decided to design a business card which would contain all aspects of perfect employee: contact information, professionalism, engineering skills, and even more to be used as useful gadget.
This business card is not a piece of paper, but PCB with Microcontroller and memory. PIC 24FJ64GB002 microcontroller contains an USB interface that enables card to act as generic flash stick. That can be plugged to PC USB port. It contains an autorun function that automatically loads resume and other portfolio. Card also can be used for other applications like data acquisition or other tasks. But probably main purpose is to serve as highway to engineering job position and it is worth trying.
Probably you remember we mentioned about Open Source PIC18F USB HID framework. So here it is – a project based on it. And it looks really cool and this is not about circuit and connectivity, but look and idea. Circuit is built around same PIC18F2550 microcontroller with minimal component count. Meter has one RGB LED and couple analogue Hi-Fi UV meters.
The device speaks itself about what it does – microcontroller reads performance counter data from PC via USB, then sends PWM signals to UV meters according to CPU or Network load. RGB LED is used to indicate HDD events. It changes intensity on utilization level and color depending on reading, writing or even both. On PC side there is a Visual Studio 2008 C# host application working to ensure communication with target. Overall this is a fun device that can be built as standalone device or integrated as PC case mod.
Probably today USB interface is near a standard in embedded projects. Probably most of them are based on emulated COM port on computer and need additional driver to be installed. It is always better when things work instantly when you plug your project to PC.
This is a great Open Source project of USB generic Hid device that is based on PIC18F microcontroller and works well on Windows. Actually this is a framework to cover Windows Host side and microcontroller side. By using simple prewritten commands you can virtually do anything with MCU-PC communications. PC side is based on Visual Studio C# class library while MCU firmware has prewritten functions to communicate with Windows – Host application. PIC18F has a built in USB interface, so there is a minimal count of external components to set it working. The information is well documented and there are couple examples to get going. So, no more pain with USB.
