Excellent example but this is a good reason why we should use a 7segment display.
6 digits with Ldmicro is almost unreadable, or you should use buffers / latches, which makes the use of a controller much less attractive. I once made a program for serial(uart) HPDL2614 display, unfortunately, that they are so small. I think there are many of us are searching for an instruction(s) that can display text or numbers in a good and inexpensive way. 7segment display are a good example, LCD's and SPI peripherals also. But I am happy with what you've already done, much more transparency in the program, bugs out, detailed instructions, etc ....

Duh... I'm getting old, attached the HPDL2614 picture.
thank (by susu)
you can tell me and everyone 32pin version 328 chip is not. Arduino pro mini thank you

I'm not sure that I correctly and fully understood you. You can use the official version of LDmicro from http://www.cq.cx/ladder.pl and select any microcontroller that shown on the attached image.

You can use the unofficial version of LDmicro from https://github.com/LDmicro/LDmicro/releases and select any microcontroller that shown on the attached image. Almost all of these MCUs was tested by different people with different Ladder Diagrams LD.

You can also sponsor support the new MCU.
The addition to the list of processors AVR with a change in package type (eg ATmega8 PDIP -> ATmega8 TQFP) or (ATmega328 PDIP -> ATmega328 32-Pin packages) I set price at $10 (0.5 hour). The addition to the list of processors new MCU will cost $20 (1 hour). DONE - means was tested, TODO - means not tested. The possible MCU you can see on the attached image. Please contact [email protected] Development of LDmicro continues under the GPL v3.

Also you can read top of threads http://www.cq.cx/ladder-forum.pl?action=viewthread&parent=4832 http://cq.cx/ladder-forum.pl?action=viewthread&parent=4947 and change log from Release 3.0.0 to 3.5.4

You can use old Arduino UNO based at ATmega8 https://www.arduino.cc/en/Reference/Atmega8Hardware Please read https://github.com/LDmicro/LDm...rd-without-an-Arduino-software
thank you (by susu)
I'm poor students do not have money to pay for ban.neu you help thank you very much

No run UART for pic 16f877A help thank you

no run down counter pic 16f877a help thank
help (by july)
Simulation ok put into practice not running

I changed pins connections in swatch1.ld SWATCH1\PROTEUS directory in zip file contain Proteus_v7.1 project with PIC16F877A. It work as expected.

PORTA has no Pull-up resistors in inputs. If you don't use external resistors then X1, X2, X3 buttons not work.

You can select PORTB with internal inputs Pull-up resistors.

I can not run down counter. I can help you.thank

There is bug with 'Formatted string over UART' with negative numbers. I need a time.
CTR reversive counter is worked right.

Fragment of manual.txt
... > FORMATTED STRING OVER UART var -{"Pressure: \3\r\n"}- ... If the variable might be negative, then use `\-3d' (or `\-4d' etc.) instead. That will cause LDmicro to print a leading space for positive numbers, and a leading minus sign for negative numbers. ...

1) You are right. CTD down counter in releases from v3.5.2 to v3.5.4 has critical decrement error. It will be fixed in near time. 2)There is NO bug with 'Formatted string over UART' 3)If the variable might be negative, then use `\-3d' (or `\-4d' etc.) in 'Formatted string over UART'. __ || _____ R1 ___________________ C1 _________________ || 0007||-------] [---------------{"value: \-3\r\n"}--------||
