A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
ds30loader is an 100% open source bootloader for the Micropchip dsPIC30F family of digital signal processing microcontrollers. It supports all devices out of the box, only minor adjustments need to be done in firmware.
The firmware is programmed in asm30 and comes with a preconfigured MPLAB-project. The GUI comes with sourcecode in both c# and vb6. The firmware is open source, supports programming of configuration bits, its size is less than 100 words and works through the UART port.
