Tutorial 20 (th-cam.com/video/Tr6mZwcGyh8/w-d-xo.html) improves on programming the I2C LCD and also resolved associated issues with timers, UART, encoder and the 20x4 I2C LCD.
Hello my friend, can the PCF8574T I/O module be programmed to increase the inputs and outputs? Can you help me with that through an example? thanks a lot for your effort
Sir I done I2c program as in video . But I work with d drive. Is it possible or not . In video says only C Mode means what? I am not understand. please clear it. Send me solution
See how to configure LDmicro in C mode in this link if you are want to modify the logic th-cam.com/video/1ooMWbz8Zzs/w-d-xo.html You can also download the hex file from the download link in the description and upload it directly to your Arduino Nano with AVRDUDESS or XLOADER
Onos tech... I have a delay problem when I'm using the I2C. In the counter test and in other tests, the delay is greater, than what was set .. Would the I2C address be the problem?
I don't think the I2C address is the problem. I have a similar experience and I am still trying to figure out the issue. I think the more I2C instructions in the program is what is causing it. For the time being, I did a workaround in the video with the link below with the DS3231 RTC module that produces the seconds pulse. th-cam.com/video/yTvP6C1ZHeU/w-d-xo.html
@@OnosTech I understand... It's just that in the example of the counter that you showed in the video it seemed correct in 100ms, but what I did here was bigger than 100ms, and this is adjusted to 100ms. I'm going to get a DS3231 and give it a try...Thanks a lot!
I have done more testing. My first observation is that the more I2C instructions in a program affects the timers accuracy. Secondly, the PLC cycle time should not be less than 10ms and if it goes up to 100ms, the Encoder instruction function is affected. My next video will be on using just two I2C instructions to correct this issue.
i have problem. 1. when i update fie Hex from AVGGCC, 2 pins RX TX is both unusable. do you know how to fix? 2. a used arduino nano, but I2C not suport to atmega 328 32 pins, and, 2 pins A6 A7 is unusable !
1. I will verify and revert. 2. Please "Create New Issues..." from the "Help" menu of LDmicro so that the developers can resolved and update with a new version or post it on the forum: cq.cx/ladder-forum.pl. I may also do same.
i have issue that is problem for some people, please note to every one in other video. * If you wanto change I2C adress, you have to change in 2 place 1. Library in Ldmicro program folder 2. Library in project folder I changed LCD 0x3F to 0x27 and taked long time to find out zzz!!

Onos Tech this is brilliant my brother. I am wowed, I am proud of you, I am out of words. Keep it up, and God bless!
Many many thanks
This is a great tutorial, perfect base for a real plc, thanks a lot for your effort.
Thanks for all your support too.
Thank you very much OnosTech for sharing your knowledge with us.
I love LDmicro, because I don't know how to write the code.
It's my pleasure. I love LDmicro too. It makes programming easy for non programmers and great for technicians too.
XOD IDE also the best for non programmers, but only for Arduino. Hopefully in the future both LDmicro and XOD will support ESP32.
Great, very great. And very good explanation. U good teacher. Thanks.
Thank you too. 😊😊😊
Excelentes Exemplos
Thanks
Thank you very much friend for your Tutorial.
It's my pleasure
@@OnosTech Can you prepare a Tutorial on GPS Clock based on Neo6M module using Ldmicro.
@@jsrabhi I will add it to the list of tutorials and work towards it. Many thanks for the suggestion
@@OnosTech My Pleasure..👍
Super!!!! Thank You 😀
You are welcome

Sir thank you so much for your toturial. May i ask if whats the name of the website or software in making ur circuit diagram.
This was with PowerPoint
Bom o video bem explicado tem como fazer arduino mega no proteus
Thanks. I am only using the LDmicro simulator and breadboard for now.

Kindly test with this program to see if Rx and Tx is now stable th-cam.com/video/Tr6mZwcGyh8/w-d-xo.html
como converter arquivo para hex???
This video will show you how. th-cam.com/video/1ooMWbz8Zzs/w-d-xo.html

* If you wanto change I2C adress, you have to change in 2 place
1. Library in Ldmicro program folder
2. Library in project folder
I changed LCD 0x3F to 0x27 and taked long time to find out zzz!!
This is very true when it is for an existing project since the library files have been imported from the LDmicro folder to project folder.
Sir
Download Hex file link not open
Please help
Everything looks okay from my end. Try to download with another browser
What next? 😁
Programming PIC in C mode, SIM800L SMS control and then ESP-01 WiFi.
@@OnosTech Are You planing menu or submenu on LCD i2c?
This would be very helpful.
There is a plan for it. But it will be when the the new update of LDmicro that will simplify it like the "Formatted String Over" is released.
