| Problem with Nokia 3310 |
 Posted: Mon May 19, 2008 2:54 pm |

Hi,
i use a Pic18F452 and the Nokia 3310 display with the sample from www.techdesign.be/projects/012/012.htm
My problem is, that all char. from the table5 are not shown correct on the display. I use to compile the CCS 4.025 an i cant find the problem.
Can anyone help me, please??
many greetings
Bobby
ps: sorry for my bad english.
Here my code:

#define nok_sclk PIN_D5
#define nok_sda PIN_D4
#define nok_dc PIN_C5

int16 ddram;
char plot_value;
int32 plot_value32;
int32 plot_umsb,plot_lmsb,plot_ulsb,plot_llsb;

I'm having a funny sort of problem. I'm using a '628 with Michel Bavin's driver (the one above). The 3310 is on PORT B:
nok_sclk - B1
nok_sda - B2
nok_dc - B3
nok_cs - B4
nok_res - B5
I'm providing power to the LCD from A0, through two 4148 diodes (to drop the voltage to the acceptable ~3.3v).I've checked the voltage at the LCD's Vcc. It's about 3.2v. I've also connected the clock, data and other pins through 1k resistors to prevent frying the PCD8544 driver chip.
I've used the example code given in the driver
| Code: | nokia_init();
nokia_gotoxy(0,0);
printf(nokia_printchar,"test???"); |
I've also used this | Code: | while(1)
{
output_toggle(pin_a1);
delay_ms(500);
} |
with an LED at the end of the code as a sort of 'checkpoint'. The code seems fine to me, and the LED flashes away merrily, but I see nothing on the display.
Now the funny part - the LCD works fine through my parallel port using LCDInfo. Occasionally, the LCD fails to display anything. But even then, when I exit LCDInfo, a horizontal line pops up on the LCD for a fraction of a second showing me that the LCD is still working.
I've been trying to get the LCD working for quite some time now, and I'm kinda stumped. Suggestions? Advice? Help?

Another thing - in the 'Absolute Maximum Ratings' section of the the PCD8544 datasheet, it says that Vdd can be a maximum of 7v. Does this mean I can run the LCD at PIC voltages (ie 5v)? Or is there a reason I must go through the drop diode/resistor ritual?

Yes, it can. But nominal values are 3V3.
