Hello all,
I thought this little board came out nice so I thought I would share it with all of you. I love the ISP option of the Dallas HSMs, but I find most using a max232/233 and having to connect this IC as well as a serial connector to be somewhat troubling from time to time, especially when I am breadboarding circuits with them to test out new ICs to me. As in the recent case of my posts, I am building a digi recorder and testing the DACs, ADCs, and other parts was getting to me. I had been using the 8052.com SBC to program them, as I built mine using a 40 pin IC socket. I came across a 40 pin IC socket, somewhat like the ZIF sockets for computer CPUs, and built this : http://www.geocities.com/coloradopics2005/8051p.jpg It would be neat if the next revision of the 8052.com SBC left enough clearance for this type of socket. Hint hint, Craig.. :) It makes programming a Dallas HSM and popping it onto a bread board really easy, and since I often like to run the HSMs at higher frequencies, using this doesn't require me to set down and calculate baud rates. The board has a standard 11.0592Mhz xtal, as well as RX/TX leds. Kinda cool. It makes me wonder if anyone else has something similar for their breadboarding applications? Also, the use of the 233a means external caps are not required. |
