ATTINY2313 PROGRAMMER COM PORT RS232 PONYPROG

I had to program an ATTiny2313 for a specific application. After some research, I found numerous circuits, but due to limited resources and issues with my computer, the simple circuits didn’t allow me to work efficiently.

In the end, I managed to program the ATTiny2313 successfully. My savior was the COM port. I attempted to program it using the ATmega8 on the Electronics DIY site (ARV programmer: http://www.electronics-diy.com/avr_programmer.php), and it worked smoothly with the ATTiny2313.

I give the oscillator section in a separate diagram so that the circuit diagram cannot be mixed too much.

The circuit I designed is quite straightforward. I assembled it directly on a perforated board instead of opting for a printed circuit because of its simplicity. This circuit allows for programming an ATtiny2313 and includes a prepared socket, additional crystal arrangement, and ICSP for future program updates. If I need to modify the program for different purposes, I can easily make the necessary connections.

In addition to setting up the circuit, I require a 5-volt power supply. I can source it from an adapter or draw power from the computer’s USB port if needed.

To install the program, I use PonyProg. After connecting the circuit, I navigate to Setup/Interface setup in the upper menu and configure the I/O settings as Serial programmer, SI Prog API, COM1. Then, I select the processor model from the top menu, open the hex file by clicking on the yellow folder icon, and press the “write to program memory-flash” button.

The ATtiny2313 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. Its efficiency lies in executing powerful instructions in a single clock cycle, enabling throughputs nearing 1 MIPS per MHz. This characteristic allows system designers to balance power consumption against processing speed effectively.

The term CMOS stands for “Complementary Metal Oxide Semiconductor.” In laptops, the CMOS battery plays a crucial role in powering the BIOS firmware. Even when the computer isn’t connected to a power source, the BIOS needs to remain operational, and the CMOS battery ensures its continuous functioning.
