Liking the result of this MR! Built it and am running it on my own Pis now and it's good stuff.
Suggest adding a mention of introducing the dependency on the wiringpi
package into the README, though for raspios users; that package doesn't seem to be a standard install.
edit: wtf, why does my clone's readme not show the dependencies section added. nvm me!

The wiringpi
dependency isn't introduced by my PR, it was a original dependency of the upstream. They've updated it since to remove it (but haven't incorporated any of the PRs). I've refitted that change, as it really simplifies the whole thing and resolves a number of lingering maintainability issues that are created by including it.
love this PR, can't understand why it hasn't been accepted by the maintainer
is there a way to get it to show host name in addition to IP?

Thanks! I wanted to get it working in my environment, and figured I'd share it back.

Yes, though I don't intend to do so myself. The display code is all bitmapped, so you should be aware there's no fancy scrolling/marquee functions, and getting everything to fit and look good enough is more art than anything.
The labels and such are part of the background bitmap, so those may have to be refactored, depending on how you choose to implement it. I used an online tool to convert images to bitmap arrays to made the adjustments that were needed.
The display code isn't very complicated though, and it's pretty easy to understand, even for a C novice.
I have a working host name solution that looks fine and works great and is a simple logical change. I'm not a C expert though. Some minor changes might be needed to ensure best C practices.
Ok. I can't find a way to modify the PR. So add -
char *GetHostname(void)
{
FILE *fd;
char buffer[16] = {0};
char *host = malloc(16);
fd = fopen("/etc/hostname", "r");
if(fd == NULL)
{
fprintf(stderr, "ssd1306_i2c: Unable to open /etc/hostname.\n");
return 0;
}
fgets(buffer, sizeof(buffer), fd);
fclose(fd);
strcpy(host, buffer);
return host; // Host name
}
AND Modify this routine.
void LCD_DisplaySdMemoryDf(void)
{
char *mnt_dir = "/";
FILE *fp;
char buffer[32] = {0};
float usedsize = 0;
float totalsize = 0;
char used[4] = {0};
char total[4] = {0};
char host[16] = {0};
strcpy(host, GetHostname()); // Gets the hostname
fp = popen("df / | awk '{if (NR==2) {print $3 / 1048576\" \"$2 / 1048576}}'", "r");
if (fp == NULL)
{
fprintf(stderr, "ssd1306_i2c: Unable to stat %s filesystem.\n", mnt_dir);
return;
}
fgets(buffer, sizeof(buffer), fp);
pclose(fp);
// Parse buffer
sscanf(buffer, "%f %f", &usedsize, &totalsize);
sprintf_fix(total, 3, totalsize);
sprintf_fix(used, 3, usedsize);
/*
fprintf(stderr, "Disk Used: %f\tTotal: %f\n", usedsize, totalsize);
fprintf(stderr, "Disk Used: %s GiB\tTotal: %s GiB\n", used, total);
*/
OLED_ClearLint(0, 1); //clear IP address
OLED_ClearLint(2, 4);
OLED_ShowString(8, 0, host, 8); // Display Hostname
OLED_DrawPartBMP(0, 2, 128, 4, BMP, 2);
OLED_ShowString(90, 3, total, 8);
OLED_ShowString(55, 3, used, 8);
}
GitHub newbie here. How do I get the new code for this PR? I can see the comparison between old and new but cannot find a way to get the new code only. Want to try out the improvements.

Probably easiest just to pull my fork of the repo. They don't seem to be responding to PRs, and worse, seen to be copying changes from the submitted PRs without attribution (which is pretty reprehensible).
So, I would install from git clone https://github.com/darkgrue/U6143_ssd1306.git and not from git clone https://github.com/UCTRONICS/U6143_ssd1306.git
as your README says, correct?
Yeah, that was written with the assumption that they'd be playing nice with the PRs, but they're not, so...

Thank you very much for your help and for creating this improved program. Very cool for me to pick up working with c and pis.
You're quite welcome, have fun! =)
