Hi,

I just bought a AT89C2051 MicroController and can't seem to find a programmer that supports it. I"ve tried Keil Uvision3, Flip (all versions), and WinISP. If anyone know a program that works fairly well with this microcontroller, also versions, that would be a great help.

Thank you.

AT89C2051 is not an ISP so FLIP or winISP will not support it.
here are some programmers which are often used for the programming...

Hardware: http://www.kmitl.ac.th/~kswichit%20/easy1/easy.htm
Software: http://www.kmitl.ac.th/~kswichit%20/ez4/ez4.html
PCB: http://www.kmitl.ac.th/~kswichit%20/easy1puiu/easyp12.htm

Just try google and look for AT89C2051 Programmer. you will get many of them

I have tried EZdownloader(all versions) but the ports available is limited. The only options for the earlier version is port 1-4, but the port my serial is on is port 9. Version 4 has a search option, but yet it doesn't detect it. I"m using an RS-232 to USB, so the USB is acting as a serial port.
I've already googled for programmers, but have found none that works.
If anyone know of another one, or maybe something with EZ downloader that I don't now about,
Please let me know.

Thank you,

talk to the guy who created the software tell him about your problem and ask for the source code. I think they are using Borland Delphi for making the softwares... or ask for notes on how to make this loader software in VB. so i can help you with it..

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
