Regarding this project, https://pic16f628a.blogspot.com/2010/09/pic16f628a-ds1820-4-digit-seven-segment.html I'm having trouble compiling and I don't know if I'm doing something wrong or there's something wrong with the code itself. I'm trying to compile this code in MPLAB with Hi-Tech C as the compiler. I get a bunch of errors when I build the file.
Here's the error message:
Could someone try to compile the code and let me know if it works on their end? Thanks
