| more than 8 custom characters with hd44780 lcd driver CGRAM |

Is it possible that more than 8 custom characters with HD44780 lcd driver?
I want to say yes, but there is some of rules for this driver and also i hope so this legal way because of i have edited CCS C library's driver for LCD.C
There are two versions of code below. First one is (LCD_CGRAM_TR.c) for all PIC, second one is (LCD_CGRAM_TR_RAM.c) for higher hardware source and RAM capacities for example 18F series PIC. But both of them do same work and i have tried a few times works nice. I could not find any bugs and problem.
So if you want to use 6 pin (without R/W) just you write FALSE in related define RW line. But in this way you do not access more than 8 custom characters. you access TURKISH characters or some i created characters. I called them LCD_TURKISH and MORE_CUSTOM_CHARACTERS in the codes. You must define one of them with RW FALSE mode. We do not need R/W pin because we write just 8 characters to CGRAM in lcd_init(); function.
On the other hand 7 pin (with R/W) just you write related PIN related define RW line. With this way you access more than 8 custom characters. so you must define LCD_TURKISH and MORE_CUSTOM_CHARACTERS before your codes. The program send custom characters to CGRAM before using and show on the lcd after load immediately. We use R/W pin because of we read last cursor's position from DDRAM's address. When we load the data of CGRAM,DDRAM's lost last address. We solve this problem before read DDRAM's address. You must be careful you do not show at same time same CGRAM data. I think that you understand when you work with this codes 
Best regards,

| Hi! Thanks for sharing your work. I note it that your library takes -along with my code- 91 percent of the ram of my uC. But I don't care that for now. |

I wanted to ask if this code will work for the Arduino controller. Moreover, this code is for which controller.
Please reply. |

This is a forum for PIC's using CCS C.
The header for the driver refers to the PIC18 family.
So, no it won't work 'as is', but the basic idea can be adapted. |
