A lot of the code is duplicated since each sketch built on the previous ones. 8 BIT BREADBOARD COMPUTER. And many of those are either moving on to more advanced projects or using slightly different hardware for the build. I do not want to have to buy an expensive programmer when it is only doing the simple task of writing the data and moving the address, so I have decided to make it on an Arduino. Building a Z80 Breadboard Computer. Since I’ve already written code to write to a chip with software data protection via a Z80 I thought it would be helpful to update my own ‘BenPrommer’ to handle the 28C256 and to document both the hardware and software changes needed. Since the Arduino doesn’t have enough pins to directly control all of the address, data, and control lines of the EEPROM, two 74HC595 shift registers are used for the 11 address lines (15 for the 28C256) and the output enable control line. download the GitHub extension for Visual Studio, Add sketch for microcode with flags register, Add STA, LDI, and JMP instructions to CPU microcode, Fix diagram to match pinout used in code and video, Build an 8-bit decimal display for our 8-bit computer, Reprogramming CPU microcode with an Arduino, Adding more machine language instructions to the CPU. EPROM programmers can be pricey. Initially, the first distraction came from watching and being engrossed in Ben Eater's YouTube videos, where he works through building a computer using discrete logic integrated circuits, supported in part by some modern technology - more of that later. This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar parallel EEPROMs using an Arduino. There’s a much larger series of videos about this project on YouTube as well.

Comparing the pinouts for the 28C16 and 28C256 shows that they both have pretty similar layouts. Arduino ‎(Nano)‎ EEPROM Programmer -Ben Eater. But there’s a catch with the 28C256: it has something called software data protection (SDP), which protects data from being accidentally overwritten. It begins by setting the data pins to output and asserting /CE, We then sent the command sequence by writing specific bytes to specific addresses. Need Help with EEPROM Programmer. If nothing happens, download GitHub Desktop and try again. These chips are used widely in hobby projects and because they are Intel/IBM compatible, they will work as drop-in replacements for old EPROM chips in things like the KIM-1 or Synertek SYM-1. This listing didn't have any reviews so I took a bit of a gamble but it's spot on! Après l’avoir dessoudée, il est préconisé de la connecter à un programmateur … 8 BIT BEN EATER BREADBOARD COMPUTER. And we can finish off by moving the /WE connection from Arduino pin D13 to pin A2 and adding connections from A1 to /OE and from A0 to /CE. There ha This is also the pin driving the on board LED and I’d rather use that for status information without risking corrupting the EEPROM.

Ben’s design permanently connects /CE to ground and drives /OE via one of the 74HC595 shift registers. Three capacitors is probably overkill but it took me a lot of debigging before I realised I needed them. If you have a dedicated EEPROM programmer this is not a problem, the programmer will handle the data protection for you, but many hobbyists prefer to save a few pennies and using Ben’s own breadboard EEPROM programmer. Again, you’ll likely want more context from the full series of videos, but here’s the video describing the code: This EEPROM programmer was designed as part of a larger project to build an 8-bit computer from scratch.

Common Anode 7-Segment Display version of Ben Eater's eeprom-programmer - multiplexed-display.ino. My hardware is not 100% like yours, so I just used some pieces of your code: void writeEEPROMCurrent(byte data); And some of those are using larger EEPROM chips such as the 28C256. I wanted one of these to follow allong with Ben Eater's 6502 computer project and I didn't want to have to deal with customs duties or to wait a really long time. The key routines for this article are writeEEPROMSDP which writes a byte of data whilst SDP is enabled and disableSDP which disables SDP so you can write to the chip with the normal writeEEPROM function. Code and schematics are available on my Github, Couch to 64k – a.k.a. Documents. Image not available. Circuit. You’ll probably want to watch the whole 8-bit computer playlist (see below) for this to really make sense, but the specific videos describing the code here are: The code in /microcode-eeprom-with-flags adds functionality for a flags register to the microcode above to support conditional instructions.

This is a good place to start if you’re looking for the fastest way to make sense of this repo: The code in /multiplexed-display is for programming an EEPROM to be used to decode 8-bit values and drive a 4-digit 7-segment display. Ben Eater. We can now turn to the software. I'm trying to modify Ben Eater's eeprom programmer to flash a 32K eeprom, since the arduino has 32K of program data total the data wouldn't fit in the program. I’m assuming here that you already have Ben’s programmer for the 28C16 available to modify. You can do the same with the 28C256 if the SDP is disabled, but if it’s enabled then you need to send a specific ‘command sequence’ to the chip.
