Dear Friend, I am working on a LPC932, and am trying to program the device w/ minimal hardware. I don't have any debugging boards EPM900 or whatever. I have tried to mimic the hardware of such a board and enter ISP Bootloader w/ Three pulses to reset method. I plan to do this very soon. In case any of you have already tried it, please let me know. In case you have the schematic of the EPM900 board (compatiable w/ FlashMagic) please let me know. Also, it would be great if you know places where I can get sample board. Your reply will be very helpful in carrying out my low cost academic project as a part of my university degree. Yours Sincerely, Aravindh Krishnamoorthy
Dear Mr. John, I am an undergraduate student studying in India. If I could afford such a board, I wouldn't have posted the message in the first place.
Perhaps you should consider another 8052... there are many from Atmel and Philips that can be programmed through the 8052 UART with no additional external hardware except a temporary connection between PSEN and GND... and that can be unnecessary if the right software is used. The software to program them (FLIP, FlashMagic) is also free. So your only new cost would be a $10 microcontroller.
