# this together during an all-nighter on 2017-Oct-19. # Normally takes 196 seconds to program a 28C64, and 32 seconds to read. Python programming script (still a lot of issues - Linux: Need minicom to connect first and leave without reset OSX: doesn't work at all - always get 'eh'): #!/usr/bin/env python2.7 - Introduced + and - to alter k_uTime_WritePulse_uS For this project, besides my Arduino Mega, I use an SD Card module, an LCD display and two push buttons to handle the events. Viewed 144 times 1 Im trying to use my Arduino Mega as an EEPROM memory writer. - corrected SDP (un)protect adresses & k_uTime_WriteDelay_uS Arduino Mega as a EEPROM Programmer for Winbond W29EE011 memories. Functions in the EEPROM class is automatically included with the. The microcontroller on the Arduino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off (like a tiny hard drive).

delayMicroseconds(k_uTime_WritePulse_uS) Learn how to use EEPROM, short for electrically erasable programmable read-only memory, on Arduino boards. static const long int k_uTime_WriteDelay_uS = 500 // delay between byte writes - needed for at28c16 Reading and writing is now orders-of-magnitude quicker.
during reads and writes were about 10,000 times too big! Now, the values are stored, and even if you reboot your Arduino board with a totally different program, those values will still be here, at the addresses 0 and 3. We write here 2 values in the EEPROM memory: Number 7 at the address number 0. - properly looked at timings on the Atmel datasheet, and worked out that my delays First, you have to include the EEPROM library at the top of your file.

- refactored code a bit (split loop() into different functions) (doesn't matter if you write a ROM immediately after, but does matter if you use -unprotect in isolation) 10th Dec 2017 - Fixed one-byte EEPROM corruption (always byte 0) when unprotecting an EEPROM
7th Dec 2017 - Updates from Dave Curran of Tynemouth Software, adding commands to enable/disable SDP. Dec 2017 - Slide code tartups, to remove compiler errors for new Arduino IDE (1.8.5). The last guy claims that: When the Arduino is in reset, all pins act like they aren't connected to anything.

Header from INO: // EEPROM Programmer - code for an Arduino Mega 2560 3, After reset the Arduino always checks this programming flag in it's EEPROM and if it's present it either does not touch the relays or set them to the same position ON/OFF depending on the value it read back from the EEPROM. Microcontroller 24 93 Series EEPROM Programmer Burner Memory Chip SP200S /w Mini. PCB Eagle+Gerber (Elecrow/Jlcpcb) are in EEpromer.zip: Just upload sketch into Mega 2560 arduino.īuild and attach adapter (LED's + resistors are optional):
