Hi, This is my first try in this forum. I am really impressed by the way the forum progresses. I would like to thank the organiser for giving such a grrrrrrrrrreat GuestBook . I want an assembly routine to calculate SQUARE ROOT OF A DECIMAL NUMBER . eg:- square root of 0.81 should give me 0.9 Does any one have the routine with you ??? I think , square root algorithm in C is also needed ... Thanx in advance. karthik bala guru

KEIL to SDCC conversion Tool :-) =============================== Could i save still more time ??? Is there any tool that converts code in KEIL to directly into that of SDCC ??? That is, a tool that translates KEIL syntax into that of the SDCC syntax without too much of manual interruption . a lazy dude's way, but still saves time and money !! Let me know if ther is any such coool tool . karthik bala guru tkarthikbalaguru@yahoo.co.in

The following was forwarded to me by a friend of mine . Do add some more if u find anything with u or from others !! Advantages of Keil - * smaller code size than that produced by SDCC for the same program .(((very Gr8 point indeed))))!! * Good Documentation and Employees available for a good handsome of money. * Excellent GUI. Disadvantages of Keil- * Price is toooooo high. * Price for upgradation toooo !!(terrible dude) Advantages of SDCC - * Free * Open Source * On both Linux and Windows * Vast Net community behind it Disadvantages of SDCC- * Developers r rare to find * Documentation is still poor and way behind that of KEIL. * No GUI, only command line instructions Add some more friends !! Learning is fun !! karthik bala guru tkarthikbalaguru@yahoo.co.in

Hi all, I am in a hard time to get a suitable IDE cum compiler to program in C for AT89C2051, I am using the evaluation version of KEIL C51, but you know there is a limitation on programming 2051 by KEIL evaluation as the address starts from 800h, so I changed the hex code and the address I started from 0000 manually and according to the length information of the hex code I changed all the address information of the output hex file by Keil, but IT is not working when i downloaded the modified hex file in my 2051 chip., can anyone tell me what is the other secret behind this ? Is not it possible at all to use the hex code generated by evaluation keil c51 on 2051 which has only 2KB flash memory ? I would appriciate your help.

Hell Experts, Sorry... away from the topic,,,, but you embedded guys should have come across the below problem. So,...do help this chap...... ! I have a board with ATMEL 89c51 interfaced with 1 MB data memory and 0.5 MB program Memory, a keypad and lcd interface. I am able to port and run a particular application built using KEIL successfully in the 89c51 controller and store the data got from the user into the flash. The software is perfect. I have many such boards and it runs perfectly. But, at times the board/controller goes into a hanging condition while getting the data from the user and the data in the flash memory is lost. Using our another serial port software i am able to get the data stored just before the controller went into the hanging condition from the flash memory in the board . The same board works fine the other day with the same software in the same condition in which the board came to standstill the previous day. I am really confused . I am unable to find or predict the moment it will go into hanging condition . I am unable to find the moment i will lose my data. It hangs at certain times if the data is low and at times if the data is high . I am Really confused . Has anyone come across such problem ? where is the problem ? y is it unpredictable like windows ?? Should the problem be with the software or with the hardware ? but most of the times the software works and there is no such hanging problem . But why should it hang at certain times ??? How to avoid it ?Plz do help me. Xpecting ur reply, karthik bala guru.T linladn@yahoo.co.in tkarthikbalaguru@yahoo.co.in
