Modern compatible microcontrollers are available from multiple vendors, in all shapes and sizes, and with a wide range of peripherals. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. This section will be brief, as I built my programming shield some time ago. I've attached the schematic and pictures of the assembled board.

The PDF of the schematic can be found in the repository. Install at89overlord. It's source code can be found here.

Upload built IntelHex file to the chip. Assemble the circuit according to schematic. A PDF version can be found in the repository. We start by including the AT89X header from sdcc. It contains macros for interacting with registers as if they were variables. We also include stdint. An interrupt occurs when the Timer0 overflows.

Every time the Timer0 overflows the counter is decreased. If it's equal to zero it's reset, and the led state is changed. We configure the timer module and await changes in the led state control variable.

TMOD is the timer mode control register. TL0 and TH0 are Timer0 control registers. Question 11 months ago on Step 6. Hi piotrb5e3, I find myself into some trouble using the software, maybe you can helpme: I can read the AT89C, but I cannot write to it. I get an error message at the Verification step "at89overlord.

AT89CommException: Verification error. Mismatch at byte 0x0" , any idea where the error may be? I use Linux Mint, and the program is a simple blink using P1. Thanks in advance! Answer 11 months ago. It sounds like a hardware issue. Reply 11 months ago. I tried with a different IR device, to enable the 12V to write. I also reviewed a couple resistors and one of them had a wrong value. No harm, just no current or just too little for the circuit to work. So far, everything works as expected!!!!

I could write and then read to check, and the result file is exactly what I flashed at the beginning! Thanks piotrb5e3, for the project and the support! Every Microprocessor has its own instruction set. Once you learn that instruction set you can even program it via machine language. I used to do that back then. And there is so many thing you can do with such 8 bit controllers. Did the same with MPUs as well.

By piotrb5e3 Follow. About: Passionate programmer by day, hardware hacker by night. Features: 2. Add Teacher Note. You will have to program the programmer board: 1.

Clone the repository. Build and upload the sketch from the Arduino IDE. Create a python virtual environment. Verify installation. Clone a simple blink project. Build the application. Locate Arduino's serial port. You should see the green LED flash with a frequency of around 0. Participated in the Arduino Contest View Contest. Did you make this project? Share it with us!

AT89C2051 8-bit Microcontroller With 2K Bytes Flash

A simple programmer for the Atmel AT89c microcontrollers. This is one of the simplest programmers. It was designed using common components, with respect to simple construction. It connects directly to a PC parallel port. Software is written in Pascal, the new version uses the Turbo Vision user interface. It should work with no problem on the first try. Both software versions support so-called DEBUG mode, that should greatly simplify any troubleshooting.
