hi hd44780
shared within the forum. How can I use the 2nd line in the serial lcd program. How can I specify the spacing I want in rows?

I want to write it in different places such as the beginning, middle and end of the 1st line. I could not use the 2nd line at all, I would appreciate if you can help.

I have uploaded the whole file here. I'm thinking of using a 2x16 screen. how can i use different fields of rows. and if possible how do i read 1024 for an adc reading 5volt and show it on the screen.

1)Hello you can start with this tutorial:

2) here you have the commands for col and row

thank you dear alex for me to learn again. do you recommend this serial method or I2C method. I use microchip 16f887 in general. I would be grateful for any suggestions

If I show the status of a few digital outputs and one ADC reading on the screen, I think it will reach 70% occupancy. Will this be an extreme problem for this processor, I will start the lessons after I get your opinion on them. Thank you in advance.

Hi smorc, yes, the limitation using the serial lcd method is that it uses a lot of memory, I wasn´t able to use I2C with ldmicro, maybe you could give it a try. On the other hand you can "play" (test) with different ladder configuration for reducing space, see image attach, I had some memory problems until I tested other ways to reduce

yes, when I look at it, if I choose a processor like the atmega2560, it can knit my work very comfortably. The memory problem for the 16f series is quite a lot.

I've never used atmel before but I think it'll be easy

I'm going to start working on it.
first, my program is in the form of few commands. If it is not enough, I will continue with Atmel. I think it will take some time. Thank you very much for the information.
