Writing Text on LCD
PostPosted: Sat Jan 06, 2024 9:16 am     Reply with quote
Hello,

I'm using the CCS compiler. I want to print text on an LCD screen. Normally, I use the glcd_text57(); function, which writes text horizontally. However, I'd like to write text as shown in the image, vertically. Could you please help me achieve this or suggest an alternative method?

Thank you in advance for your assistance.

1st I'd ask google to search , see if someone has already done this !
if not you'll need to
1) create a font table for the 'sideways' characters
2) create a 'map' of 'rows and columns' for the 'sideways' locations
3) create functions to display the data( SWprint(........)

Both involve reading the GLCD datasheet and 'mapping out' the pixels. You should be able to use the GLCD driver as a reference.

I'd start with 'A' and upper left of the display.
These days there's probably some fancy internet help to create the characters, bit by bit..old dinosaurs like me used graph paper and pencils.
Get 'A' to display in upper left corner('home'), then create 'B',test,continue with the alphabet. THEN work out the row and columns 'math'.

I'd also name variables as SW...... short for SideWays so you don't get confused with your version of the GLCD driver !!!
Yes, it'll be slow going at first, but once you get ABC, the rest should go a lot faster !

The answer depends massively on the LCD involved?. As Jay has said a
search may well find answers. Some displays do allow you to rotate the
whole screen. On others you have to code a custom font. A lot more work.

For example, I wrote a short text. The code is as follows;

#include <18f452.h>
#use delay(clock = 4000000)
#fuses HS,NOWDT,NOPUT,NOLVP,NOCPD,NOPROTECT,NODEBUG,NOBROWNOUT,NOWRT
#include <HDM64GS12.c>
#include <graphics.c>
char text1[] = "Text1";
char text2[] = "Text2";

void main()
{
setup_psp(PSP_DISABLED);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED, 0, 1);
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_CCP1(CCP_OFF);
setup_CCP2(CCP_OFF);


glcd_init(on);
glcd_text57(1,1,text1,2,ON);
delay_ms(200);
glcd_text57(1,30,text2,2,ON);
delay_ms(200);

} // end of loop

I did some research, but I haven't found anyone who uses it this way. I wonder if there is a ready-made function for it.

you need to do some more research. I quickly found some Ardunio code, seems 'vertical' is a keyword to add while googling....
honestly, to make the 'sidewriting driver' should only take 1-2 days. You've got a working 'normal' driver and the GLCD datasheet.
one possible source would be the manufacturer of the GLCD. They may have 'application notes' about doing what you want.

I don't have your GLCD ,so I can't cut test code.
