Z80 is not dead - czyli jak zbudować projekt w oparciu o ten mikroprocesor

The Z80's production has ended, and with it, an era. Perhaps we should commemorate the end of this iconic microprocessor by creating a project based on it? In this episode, I'll tell you a few words about the Z80, how you can use it and build a truly minimal system based on it. Of course, we'll try to write a simple program for the Z80, and it will also be an opportunity to learn more about how modern computers and microcontrollers work. Or maybe it will turn out that not much has changed in the 50 years since the Z80's introduction? I've posted the code for the example program I used to communicate with the Z80 and program its memory on my GitHub: https://github.com/TFrancuz/youtube/t... 00:00 - Start 02:07 - CPU vs. MCU 03:54 - Starting with the Z80 note 10:54 - Building a system based on the Z80 14:14 - AVR as a clock source for the Z80 :) 15:21 - Starting the Z80 clock timer 15:57 - Starting the first "program" on the Z80 17:48 - Connecting memory to the Z80 21:17 - How to program memory? 23:43 - What is BUSRQ useful for? 24:38 - Memory control program and the Z80 26:18 - AVR debugger for hardware debugging 29:35 - Programming the SRAM memory 30:49 - Writing the first program on the Z80 32:20 - Does it work? 39:10 - How about the first IO device and LEDs? 40:18 - IO Z80 Space 43:56 - We have a problem... 46:51 - Another problem, or rather, no improvement... 47:55 - Time for LEDs
