Need Help ?? very puzzy problem

[engahmed]

I use pic 18f87k90 with 40mhz

Use 5inch tft with ssd1963 with 16 bit data line

First when I try initialize the tft using the library of micro c not working good the but I searched for
Initialize code and I did it the screen work good but sometime
When draw rectangle or horizontal line the thick of line very small even
I activate set pen function to 10 but the vertical line work good this problem not always some time
I don't know why??? Her pic for my problem

for TFT connecting


// TFT display connections

char TFT_16bit_DataPort_Lo at LATE;
char TFT_16bit_DataPort_Hi at LATH;
sbit TFT_16bit_WR at LATD1_bit;
sbit TFT_16bit_RD at LATD2_bit;
sbit TFT_16bit_CS at LATD3_bit;
sbit TFT_16bit_RS at LATD0_bit;
sbit TFT_16bit_RST at LATD7_bit;
char TFT_16bit_DataPort_Lo_Direction at TRISE;
char TFT_16bit_DataPort_Hi_Direction at TRISH;
sbit TFT_16bit_WR_Direction at TRISD1_bit;
sbit TFT_16bit_RD_Direction at TRISD2_bit;
sbit TFT_16bit_CS_Direction at TRISD3_bit;
sbit TFT_16bit_RS_Direction at TRISD0_bit;
sbit TFT_16bit_RST_Direction at TRISD7_bit;
// End of TFT display connections



i this function to intialize the TFT

i think my feeling told the problem in intialze function !!!!

[hexreader]

Guessing a bit here, but I would have thought:

Code: Select all

char TFT_16bit_DataPort_Lo at LATE;
char TFT_16bit_DataPort_Hi at LATH;

maybe should be:

Code: Select all

char TFT_16bit_DataPort_Lo at PORTE;
char TFT_16bit_DataPort_Hi at PORTH;

Could be completely wrong... I do not have that hardware to test code on and the help files seem to suggest that LAT register is the correct option, not PORT

I see you have a second thread for the same problem.

Please do not double-post as it causes confusion and annoyance.

Let's consider this thread closed....
