sunrom atmel 89 series programmer

[saikumar5]

hello , can anyone help me in finding the solution for atmel 89series programmer circuit.actually by using proload 4.1 software, the hardware is detected and displaying the code i.e (like 89S51 is connected and 0 bytes used).so when i burn the program the software says "write successful".but the MCU which i have burned has no response when i tried to run it.
i have burned a small program which will make a port pins high and low(verified and executed using keil c).so when i have connected an led to those ports the led simply glows continuously but not toggling (which i have see in keil c).
PLZ HELP ME SO THAT MY HARDWORK IN BUILDING THE CIRCUIT CAN BE WORTHY!!!PLZZZZZZZ

Have you verified the Programmed chip?
If verify chip is successful then the problem should be with your hardware and c code.

Post your hardware and c file, some one will help you

While your programing software says, Programming Ok, it menas that. Confirm the Project hardware you have contructed is powered by 5 volts to 40 and 31 pin, 20 to gnd, Rest circuit to pin 9 and a crystal to Pins 18 and 19, and your code is perfect. The Sunrom programmer is a tried and trusted piece of invaluable equipment, all over the world by now.
Cheers

Update firmware to 4.4 version and use ProLoad 5.4.

I solve my problems with this!

Thanks for the reply;
can u plz post the firmware 4.4 version to me

MOD: Guess you never use the search box of the forum. There are quite a lot topics and DIY packs releated to the said programmer in the forum and too all over the web. This warning will remind you to use the "search" enxt time you post a requirement without searching for it.

here is archives with 4.4 hex and 5.4 proload

if the led glows continuously, did you try a longer delay between toggling the led?

example:

led pin high
delay
led pin low
delay
loop

if the led glows continuously, did you try a longer delay between toggling the led?

example:

led pin high
delay
led pin low
delay
loop

If delay has some problem ?
make LED pin Low first
delay
LED pin high
delay
in this program
led will not glow
if delay has some problem and it not returning to main program

show us your schematic of the very simple circuit.

I have modified PCB Layout for sunrom 1001-3456 , Single Side Board.

Changed to 2 Layer Board, No jumper wires.
modifies Power Supply/Requlator circuit for better filter.
used smd passive components (Resistors,Diodes)
smd filter capacitor close to vcc pin of microcontrollers.

(images attached)

will test prototype after 10 to 15 days, will post result here.

Does it program AT89S8253? Can you post the Eagle PCB .brd and .sch files?

 

[technofreaks]

I will upload PCB Layout and schematic after checking prototype.

attached is updated layout design
Note: There is no change , addition of feature, attempt is to improve PCB, solve issues related to PCB Design.
Firmware used : 1001-3456 v4.1 (1001-3456 V2)

Waiting for eagle files. Does it programm AT89S8253?

 

[technofreaks]

check here: **broken link removed**
I dont think 89series supports AT89S8253, you need ISP
check here : http://dybkowski.net/content/en/node/15

I will work on this ISP later, and upload PCB files..
