I am giving the link for the pocket programmer.
http://www.8052.com/users/Nimish/RECO0097.JPG http://www.8052.com/users/Nimish/RECO0098.JPG I have successfully programmed 89c51 using this programmer.LCD serves as good as 17" monitor.I made it on general board which makes it look ugly.I will soon do it on PCB.Disassembly works GREAT.The display code is about 6.5 KB.Rough cost of this programmer is about Rs 300 (i.e $7 US) Few limitation which I observed is 1. I am using PC keyboard.Makes things bulky(I use only 23 keys).Trying to shift to I2C 2. I have alloted space for data storage.Hence the user has to enter data within alloted space only.1kB for 89c51,89c52,89c4051. 512 bytes for 89c2051 and 256 bytes for 89c1051.Instead of this I may used the reversed opcode A5 to inform start and end of data bank. 3. Still having versatile "reset" problem This community is responsible for the success of this project.I thank all of you in helping in making my very first 8051 based project.I would be glad to get any criticism and suggestions. thanks once again. |
