High Voltage Parallel Programmer AVR

Posted by yeyen 1 Comment »

AVR has two different programming modes called Parallel Programming Mode (Parallel Mode) and Serial Downloading Mode (ISP mode).

At the Parallel Mode, the device to be programmed is put on the programmer’s socket and +12 volts programming voltage is required to its RESET pin. Communicating between the programmer and the device is done in parallel programming commands, so that the programing speed is two times faster than ISP mode. This programming mode is used to pre-program many devices or/and ISP mode cannot use due to the board design. However, most programmers except STK500 seem not to support this programming mode. Using High voltage parallel programmer can recovery wrong fuse bit setting.

Posted by yeyen 2 Comments »


Anyone here that didn’t love to play games, please raise your hand! Yeah, most people love to play games, and that’s why there are many game devices, such Sony PS3, Xbox and Nintendo is available on the market!

Of course, first thing first, you have to get a toaster. It does not matter if it is a brand new or second hand toaster, as long as it still can function. Then, you need to rip all the main parts out of the toaster and replace them with an NES board. Beside that, the orange LEDs, AC adapter, resistors, pixelglass and controller parts are included inside the toaster.
After that, keep the [...]
