I don't have Pi Zero W. Do you have some other Pi?
Actually, I was just trying it out on a Pi 3 B, although I just swapped the SD card and didn't do a fresh install. I ended up with the same result.
OK Change some code of demo.c & try.
// You can change font file
FontxFile fx32G[2];
FontxFile fx24G[2];
FontxFile fx16G[2];
Fontx_init(fx32G,"./fontx/ILGH32XB.FNT","./fontx/ILGZ32XB.FNT"); // 16x32Dot Gothic
Fontx_init(fx24G,"./fontx/ILGH24XB.FNT","./fontx/ILGZ24XB.FNT"); // 12x24Dot Gothic
Fontx_init(fx16G,"./fontx/ILGH16XB.FNT","./fontx/ILGZ16XB.FNT"); // 8x16Dot Gothic
printf("pass1\n");
FontxFile fx32M[2];
FontxFile fx24M[2];
FontxFile fx16M[2];
Fontx_init(fx32M,"./fontx/ILMH32XF.FNT","./fontx/ILMZ32XF.FNT"); // 16x32Dot Mincyo
Fontx_init(fx24M,"./fontx/ILMH24XF.FNT","./fontx/ILMZ24XF.FNT"); // 12x24Dot Mincyo
Fontx_init(fx16M,"./fontx/ILMH16XB.FNT","./fontx/ILMZ16XF.FNT"); // 8x16Dot Mincyo
printf("pass2\n");
lcdInit(screenWidth, screenHeight, offsetx, offsety);
printf("pass3\n");
lcdReset();
printf("pass4\n");
lcdSetup();
printf("pass5\n");
Hello
I have not made any changes to tft.config.
I hade already put in some debugging code in demo.c. I only made changes to the main function.
int main(int argc, char **argv)
{
int i;
int screenWidth = 0;
int screenHeight = 0;
int offsetx = 0;
int offsety = 0;
char dir[128];
char cpath[128];
printf("argv[0]=%s\n",argv[0]);
strcpy(dir, argv[0]);
for(i=strlen(dir);i>0;i--) {
if (dir[i-1] == '/') {
dir[i] = 0;
break;
} // end if
} // end for
printf("dir=%s\n",dir);
strcpy(cpath,dir);
strcat(cpath,"tft.conf");
printf("cpath=%s\n",cpath);
if (ReadTFTConfig(cpath, &screenWidth, &screenHeight, &offsetx, &offsety) == 0) {
printf("%s Not found\n",cpath);
return 0;
}
printf("ReadTFTConfig:screenWidth=%d height=%d\n",screenWidth, screenHeight);
printf("Your TFT resolution is %d x %d.\n",screenWidth, screenHeight);
printf("Your TFT offsetx is %d.\n",offsetx);
printf("Your TFT offsety is %d.\n",offsety);
// You can change font file
printf("fontx 0");
FontxFile fx32G[2];
printf("fontx 1");
FontxFile fx24G[2];
FontxFile fx16G[2];
Fontx_init(fx32G,"./fontx/ILGH32XB.FNT","./fontx/ILGZ32XB.FNT"); // 16x32Dot Gothic
Fontx_init(fx24G,"./fontx/ILGH24XB.FNT","./fontx/ILGZ24XB.FNT"); // 12x24Dot Gothic
Fontx_init(fx16G,"./fontx/ILGH16XB.FNT","./fontx/ILGZ16XB.FNT"); // 8x16Dot Gothic
printf("fontx 2");
This is what I get when I compile and run it:
argv[0]=./demo
dir=./
cpath=./tft.conf
width=240 height=320
ReadTFTConfig:screenWidth=240 height=320
Your TFT resolution is 240 x 320.
Your TFT offsetx is 0.
Your TFT offsety is 0.
Segmentation fault
It's weird because the first statement after the printf that outputs my offsety is just another printf, and I never see the output from that.
Hello again,
I started with a fresh install of the latest version of Raspberry PI OS, did sudo apt-get update, sudo apt-get upgrade and then followed the Rapsberry Pi only instructions. I did have to run sudo apt-get install git half way through, but other than that, I ran everything as the instructions indicated. I still get the segmentation fault error.
I figured it out. I was running
./demo
When I run
sudo ./demo
it works fine. So it's a permissions issue.
Older OS don't require permissions.
There may be a bug in the latest OS.
Hello,
I'm using a Pi Zero W with a generic ili9340 display. I've got it wired as per your instructions in the README.md. I followed the directions that you have labeled just for the Raspberry Pi and did not receive any errors. during setup/compiling. When everything was done I ran:
./demo
from the Raspberry-ili9340spi directory and received the following error:
Your TFT resolution is 240 x 320. Your TFT offsetx is 0. Your TFT offsety is 0. Segmentation fault
I looked through the issues and saw a recommendation to someone to use bmc2835 1.6.4, so I used the only Raspberry Pi instructions to use 1.64 instead. I still receive the same error.
Thank you
