Measure Temperature with Commodore 64 @JosipRetroBits

Josip Retro Bits In this video, we connected DS18B20 digital temperature sensor to Commodore 64. Then we learned how the 1-wire protocol works and implemented the same in assembly. In addition, you will see how I dealt with floating point numbers in assembly. Enjoy :)

Morse Code Keyer and Commodore 64 | Part One

Josip Retro Bits 2024-04-08 | This is the first part of the "Viking Morse Code Keyer" video and in this part, we will connect it to a Commodore 64 and try to capture the signals using BASIC language. We will prepare our circuit so that we can use external hardware interrupt and in the next video, we will capture Morse code signals using Assembly code and MIKRO ASSEMBLER Cartridge.

Using Arithmetic Instead of Logical Operators in Commodore Basic

Josip Retro Bits 2023-08-15 | In this video, I tested a couple of different solutions for joining two conditions in IF statements on a Commodore 64. The idea for this video came from a Facebook post to use arithmetic instead of logical operators in if statements. The goal was to compare those solutions and see which one is the fastest one.

☕ If You like this video you can buy me a coffee: ko-fi.com/josipretrobits ☕

METHODS:
==============
1 if a=0 and b=0 then
2 if a=0 then if b=0 then
3 if (a=0)*(b=0)=1 then
4 if a*a+b*b=0 then
5 if abs(a)+abs(b)=0 then

TEST CASES:
==============
1 A is equal to 0, B is equal to 0
2 A is not equal to 0, B is not equal to 0
3 A is equal to 0, B is not equal to 0
4 A is not equal to 0, B is equal to 0

TEST CODES:
==============
0 rem arithmetic check
10 s=ti:a=5:b=5
20 fori=1to200
30 if a*a+b*b=0 then c=c+1
40 next
50 df=ti-s
60 print df,c

0 rem abs sum check
10 s=ti:a=5:b=5
20 fori=1to200
30 if abs(a)+abs(b)=0 then c=c+1
40 next
50 df=ti-s
60 print df,c

0 rem equal to, operators
10 s=ti:a=5:b=5
20 fori=1to200
30 if (a=0)*(b=0)=1 then c=c+1
40 next
50 df=ti-s
60 print df,c

0 rem nested if's
10 s=ti:a=5:b=5
20 fori=1to200
30 if a=0 then if b=0 then c=c+1
40 next
50 df=ti-s
60 print df,c

0 rem classic if and
10 s=ti:a=5:b=5
20 fori=1to200
30 if a=0 and b=0 then c=c+1
40 next

Creating Mazes on Commodore 64 | With cool visual effects

Josip Retro Bits 2023-06-30 | A whole bunch of Mazes written in BASIC and C programming language. We explore the "Recursive Backtracker" algorithm and the "Recursive Division" algorithm and their implementation on the Commodore 64. In addition, you can see some Maze Art with some cool visual effects.
This video is inspired by the "Back to Basic" video and his BASIC code for creating mazes on the C64.

Assembly and Basic code together on Commodore 64 | Mikro Assembler

Josip Retro Bits 2023-06-06 | Exploring Mikro Assembler for the Commodore 64 and discovering some hidden options that allow us to merge the assembly with the base code in the same source file.
It is weird to see the assembly and basic code together in the same source file but it works really nicely and it does open some crazy possibilities :)
Mikro Assembler was released as a cartridge by Supersoft in 1983 and written by Andrew J Trott.

Big Thanks to Steve from @8BitRetroReFix channel for shots and images of Mikro Assembler cartridge used in the video.

Someone cracked my game and made it better | C programming

Josip Retro Bits 2023-05-29 | Some time ago I made a little series of Pong games; Mini-Pong made in BASIC. The second is Tiny-Pong is a pong game that runs inside Sprite written in C language. And the last one was Micro-Pong, a game of Pong that runs inside the Petscii Character.
In this video, I present a cracked version of Tiny-Pong with improved C code. Enjoy :)

I made a Commodore 64 Case | 3D Printed parts | DIY

Josip Retro Bits 2023-05-10 | I made a DIY case for the Commodore 64 that is easy to assemble and disassemble. The case is intended for C64 shortboards, and it serves me the most during final tests and before the motherboard ends up in the original case.

10 PRINT program with no RND() | Commodore 64

Josip Retro Bits 2023-04-21 | We explore different ways to create 10 PRINT MAZE without the use of the Random function. Using XOR, Modulo and other bitwise operators we create some beautiful patterns and shapes on Commodore 64.
