Hi group. I’ve recently purchased the Sparkfun Pocket AVR Programmer to connect to the ATmega328P-PU. I found a schematic at All About Circuits (https://www.allaboutcircuits.com/projects/breadboarding-and-programming-the-atmega328p-and-attiny45-in-atmel-studio-7/) that shows how to connect to the MCU. I’ve attempted this with no success. I did download and install the appropriate driver for the product. Am I missing some additional hardware that is needed? Is there a better way to connect to the MCU such that I can begin programming it?
I should share that this is my second attempt at programming. I’ve also purchased an Adafruit ItsyBitsy 32u4 3.3V controller. I was successful in programming this. However I’d prefer to use the Atmega328P as a standalone MCU which will be built in to my project.
If you have some thoughts as to what I need to look for, to test or do to make the appropriate connects, please don’t hesitate to share. I appreciate any assistance anyone can give.
That programmer uses a ATtiny2313, is that what you have selected?
Otherwise, let me offer some suggestions and things to check:
Connections:
Double-check all your connections between the programmer and the ATmega328P-PU. Make sure they match the schematic exactly.
Ensure you have proper power supply to the ATmega328P-PU (usually 5V or 3.3V, depending on your setup).
Verify the ground connection between the programmer and the MCU.
Additional hardware:
You may need a breadboard and some jumper wires if you don’t already have them.
A crystal oscillator (usually 16 MHz for Arduino-compatible setups) and two 22pF capacitors are often necessary for the ATmega328P to function properly.
Programmer settings:
Make sure you’ve selected the correct programmer in your IDE or programming software.
Verify that you’ve chosen ATmega328P as the target device.
Testing the connection:
Try using AVRDUDE (a command-line tool for programming AVR microcontrollers) to test if your programmer can communicate with the ATmega328P.
You can use a simple command like: avrdude -c usbtiny -p m328p
Alternative setup:
You might consider using an Arduino Uno as an ISP (In-System Programmer) to program your ATmega328P. This can sometimes be easier to set up and troubleshoot.
Hey I seriously doubt this is the correct location for my comment…If if is I apologize, this is my first attempt on the message board and I looked all over for an answer to my question and looked also for some "directions/guidelines on how to use this system.
My question is I have a sparkfun AVR pocket programmer and it was loaded on another laptop that has died. I have a new laptop windoes 11 and cannot locate the drivers for the programmer board. Can someone please advise? I did look at Github and saw numerous files however I was not sure which ones nor how to install them. Lastly can anyone point me in a direction for the guidelines/directions on use for this system.
Thanks in advance
