AvrBetaDevelopmentBoard

details

Similar to the BetaPicDevelopmentBoard this board is designed for testing and breadboarding AVR projects. Presently this beast only sports a 40 pin DIP socket, 4.9MHz oscillator, 10 pin ISP header, and IO pin access sockets. This was originally for the FreeRtosTest but is now being used for all mega32 development until the AvronicsKit is in full swing. even after the kit i'll likely still use this as it is a handy board.

At this point i have fitted all of the IO pins with SIP headers and added as many SIP headers to ground too. This gives me access to every pin so that i can write the drivers for i2c, spi, rs232, and general IO.

here you see the led's that allow output on the lower nibble of PORTB. I also have attached this kit to a RS232 board and am developing an RS232 driver for use with the AvronicsKit.

very low level debugging is available on this board thru the nibble shown. the four leds are tied to b0..3 so i stobe the upper and lower nibble to see internal register values. at this point the rs232 driver is fairly robust so i use a peek function to see internal registers as well. of course i only do this because i don't want to drop the loot for a ICE. while the JTAGICE mkII is an amazing deal for $300 i don't want to spend that kinda money for my side projects.
