A couple years ago I spent a good week wiring up a fairly complex EPROM programmer so I could burn a prom for my jeeps EFI system. Today I ran across this 5 version. Jay Kominek He uses shift registers to handle the addressing and IO lines, all driven directly by the parallel port. Theres no way to escape the number of pins that have to be wired up, but the schematic itself is pretty simple. By the way, arcade supply shops are a great source for cheap UV erase EPROMS. Update Id forgotten about the voltage change 3 vs 5 if I remember needed to write UV EPROMS vs EEPROMS. PNG' alt='I2c Eeprom Programmer Seriali' title='I2c Eeprom Programmer Seriali' />
With a little mod, you can certainly use this for EPROMS as well. Transforming your AVR Microcontroller to the I2. C or TWI Slave IO Expander Project. The I2. C bus read as I squared C is one of the most important embedded system serial bus interface first introduced by Philips in 1. SCL serial clock and SDA serial data respectively make the I2. C bus is a perfect choice to provide additional IO capabilities to your microcontroller project without changing your microcontroller type and design in order to increase the IO port pins. Today there are plenty choices of I2. C slave IO port expander devices available on the market such as Philips PCF8. Microchip MCP2. 30. IO ports which capable of handling I2. C standard bus speed of 1. Khz or fast speed mode of 4. Khz the Microchip MCP2. Mhz bus speed. You could read more information about using I2. C interface on my previous posted blog How to use I2. C bus on the Atmel AVR Microcontroller. The usage of I2. C slave devices is not merely for the IO expander but it also use to expand your microcontroller capabilities as well as its functionalities such as the I2. C real time clock from Maxim DS1. Using Maxim DS1. 30. Real Time Clock with Atmel AVR Microcontroller, Microchip TC1. DAC, Microchip MCP2. ADC, Microchip MCP9. Microchip 2. 4AA1. KB EEPROM. Although there are many types of sophisticated I2. C slave devices available on the market, sometimes we need the I2. C slave device which has the capabilities beyond that, something more powerful, more flexible and yet easy to be configured the answer to this requirement is to use the microcontroller it self as the I2. C slave device, that is why most of the midrange class microcontrollers have the I2. C slave peripheral feature build inside it. This is what we are going to learn on this tutorial, where the principal we learn here could be applied to other microcontroller type as well.

In order to communicate with MCP2. I2. C slave device, the I2. C master controller first has to send the START condition to take control of the I2. C bus and continue with the I2. C slave device 7 bit target address which consists of 4 bit MCP2. I2. C slave identification ID 0. TWREAD, logical 1 or write TWWRITE, logical 0 operation. After receiving its own 7 bit address then the I2. C slave device will response to the I2. C master controller by sending the acknowledge ACK signal. Once the I2. C master controller receive the I2. C slave address acknowledge ACK signal, then it will start to send the requested register address to the I2. C slave device. The I2. C master controller then will continue to send the data to this register GPIO after the acknowledge ACK signal from I2. C slave. Next the I2.
