In this blog post, I will describing how we will be using ROM routines to create a Data Input Form where we will display a message, have a user input their name and address, and take user input and display it onto the character display. The above code, we were able to produce a messageContinue reading “Data Input Form”

ROM Routines In this blog post, I will be attempting to recreate the below code using ROM routines with instructions sets designed for 6502. These instruction sets will include modifying Accumulator, Y, and X registers to display text on screen. Also with instruction sets, there are ROM Routines. The first thing I want to discussContinue reading “6502 ROM Routines”

Generating Random Number to Display

The objective of this task is to display a numeric font that is 8×8 bits onto the bitmap. By storing font using dcb directive, we place the 64 bit data into a region of memory and load that memory to display a number between 0 and 99. Creating Font to Display an 8×8 bit DigitContinue reading “Numeric Display Graphic”

First Try at Coding in Assembly Language Recently, I had the opportunity to code in assembly language. The coding was done on an emulator based off of the 6502 chip. There are 56 predetermined set of instructions for the 6502 emulator such as load accumulator (lda) and store accumulator (sta). In this blog, I willContinue reading “Assembly Language”
