Each 7-segment display can only show a single digit at a time because it is multiplexed. To achieve that a number with four-digit has to be separated into single digits by converting it to thousand, hundred, tens and unit
Is it required to modify the setpoint{persist} for using with any other microcontrollers ? I mean, in order to match with EEPROM of any other microcontrollers ?
I am getting errors in Ardiono IDE while compiling sketch: Error compiling for board Arduino Nano. undefined reference to `EEPROM_read(unsigned int)' undefined reference to `EEPROM_write(unsigned int, unsigned char)' Can you please help me with this ?
I have seen this error in Arduino IDE too. Copy the "RomLib.h" file from the ARDUINO library folder instead of the AVR library folder. There are some differences in the code. If for no other reason configuring LDmicro in C mode with the below link has proven to be more efficient for me. ruclips.net/video/1ooMWbz8Zzs/видео.html
ciao e' da un po' che non ti vedevo ..sei bravissimo e se l'unico che ci capisce davvero ..grazie
Its my pleasure.
this channel is gold mine.. new follower from Guinea
Welcome, Karounka it's good to have you here.
As usual a very good tutorial. Thanks looking forward to your next tutorial.
Many thanks
Hi dear my frind i am MedTronic.... Best wishes... Best Regards
MedTronic! It's good to have you here. Many thanks
wow, its really very good tutorial
Thank you!
sir, can i ask, why we need to convert thousand,hundred and tens ,its for 7 segment?

Details so simple
Thanks a lot 😊

No modification is required as long as the microcontroller has EEPROM and you have selected the microcontroller type from the settings menu
Thank you, Sir
Stepper motor ladder program and wiring diagram with Arduino Uno please make video for stepper motor
I will consider it
I am getting errors in Ardiono IDE while compiling sketch:
Error compiling for board Arduino Nano.
undefined reference to `EEPROM_read(unsigned int)'
undefined reference to `EEPROM_write(unsigned int, unsigned char)'
Can you please help me with this ?
Use the RomLib.h from the Arduino library folder 📁 instead of the AVR library folder 📁. There seem to some difference.
Yes Sir .. Problem solved .. Done compiling. Thank you again for your reply in lightning speed.
Thank you very much!
You're welcome!
Please Start SCADA tutorial in LDmicro
There is plan for it. But we have to complete the most relevant functions in LDmicro
@@OnosTech ok
SCADA
ruclips.net/channel/UCCRu9nezVe42ajMW6wUqxhAvideos
this channel not clear tutorial, but I hoop you are make & made clear SCADA tutorial
Sure
@@OnosTech 100%
Hi, at what point in time data is stored in eeprom?
Whenever the variable value changes
@@OnosTech Thnx
i have a problem uploading the code to arduino nano
Please explain the problem

that was the error showing when i was trying to run it in arduino ide
