24 ~ 27 Ic Pins Failure Atmega32A & 16L (by MFQ)
DEAR SIR
ATMEGA32A ATMEGA32 16PU ATMEGA32A PU ATMEGA16L SAME LOGIC TEST OF 22,23,28 & 29 PINS SAME PROG WORKING OK SAME LOGIC TEST OF 24,25,26 & 27 PINS SAME PROG NOT WORKING WHATS PROBLEM IS THERE ? TEST BY OSCILLOSCOPE & LOGIC PROBE

DEAR MPG
DO YOU FACE THIS PROBLEM ABOUT THAT (ATTACH FILE) PLEASE IF YOU HAVE ANY SOLUTION ABOUT IT INFORM. THANKS

Ihor is the man you need, not me.
I'm a PIC-man and can not change the source code of LDmicro.

I recommend using pintest.ld with different frequency on the output pins.

This will identify the outputs.

To MFQ:
You are trying to use 44 leads/pads packages of ATmega32?
(no subject) (by Ihor Nehrutsa)
40-PDIP package has a different numbering sequence of chip pins from 44-TQFP/MLF packages.
For example in 40-PDIP 26 pin is PC3, in 44-TQFP/MLF 26 pin is PC7. LDmicro now support "Atmel AVR ATmega32 40-PDIP".

I compile pintest.ld, got a pintest.hex and pintest.asm.
I developed scheme about ATMEGA32 with pintest.hex in Proteus.

Ihor, I found a bug in the editor(compatibility)
Your program PINTEST.LD looks like this in the V2.3, see the printscreen.

You can see more details in zip archive. All files attached above are in ZIP archive.
Please pay attention to excerpts from Atmel documents: ATmega32_page*.jpg ATmega32A_page*.jpg or use original www.atmel.com datasheet pdfs. I change LPC cycle time to 1ms and add CTC counters. PINTEST\pintest.ld PINTEST\pintest.hex PINTEST\pintest.asm Proteus scheme in PINTEST\pintest\PROTEUS\pintest_ATmega32.DSN. Work in Poteus 7.10. pintest_ATmega32_1.JPG pintest_ATmega32_2.JPG pintest_ATmega32_3.JPG show different horizontal scan of Y signals on oscilloscope. About asm you can read https://github.com/LDmicro/LDm...R-Studio-or-PIC-MPLAB-software

to MGP:
It is not a bug. It is a new feature of CTC. CTC moved from the end of line to leaf of a rung. After the CTC counter overflow, CTC generate OSR at its output. This feature is back compatible with old LD files. In this thread http://www.cq.cx/ladder-forum.pl?action=viewthread&parent=4832 I offered "CTC need upgrading!" and Jonathan Westhues says "That seems like a good change. It should be possible to make it as backwards-compatible for the file format always, and forwards-compatible for all programs not using the new feature; so there should be no problem with existing programs."

To MFQ and all:
I can add "Atmel AVR ATmega32 44-Pin packages" into LDmicro. It will cost $10. I can add "Atmel AVR ATmega328 32-Pin packages" It will cost $10. As I wrote earlier: " I appreciate his work at $ 20 / hour. ... Also, the addition to the list of processors AVR with a change in package type (eg ATmega8 PDIP -> ATmega8 TQFP) I set price at $10 (0.5 hour). " On the question of payment, please contact [email protected].

Sorry, I forgot you had already written this.

Dear thanks .
trying to solve my problem but there is no problem. problem in programming.exe too much different attempt on both ic atmega32 and 16 both ic status 24 25 26 27 not work but 22 23 28 29 work properly. there is no use 44 pin pakage PDIP 40 pin use
(no subject) (by MFQ)
dear use different ic use and programming but all ic shown same status
(no subject) (by MFQ)
SEE IC PACKAGE
(no subject) (by MFQ)
NEXT DAY TO TEST YOUR RECOMMENDED PROG. AT HARDWARE THEN INFORM YOU THAT IS WORK OR NOT
THANKS
(no subject) (by MFQ)
DEAR THIS PROG ALSO TESTED BUT NOT SUCCESS

Please send you pintest.hex and tested.hex

to MFQ:
Are you using JTAG interface? This is a fragment of ATmega32 datasheet: ... Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port C output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset condition becomes active, even if the clock is not running. If the JTAG interface is enabled, the pull-up resistors on pins PC5(TDI), PC3(TMS) and PC2(TCK) will be activated even if a reset occurs. The TD0 pin is tri-stated unless TAP states that shift out data are entered. Port C also serves the functions of the JTAG interface and other special features of the ATmega32 as listed on page 60. ...
