ATiny5,10 programming help

Post by rjdadio »

Hello, I am at my wits end having spent 3+ weeks trying to program a Tiny5 MCU. I have a very simple programing need for 1000+ Tiny5 MCUs. I can program Tiny 25s but to no avail I cannot program Tiny5. I have followed a number of videos showing how to program using command line avrdude and avr-gcc using a USBASP but nothing has worked. Have verified the wiring over and over so that is correct. I have a STK600 programmer with the proper board and socket for the SOT23-6 Tiny5 with Microchip studio but the tools can not ID the chip. I have used my ATMEL ICE with the proper wiring with the same outcome...can not ID the chip.
I have tried everything! I even wiped a computer and reloaded all the software and tool chain only to have the same result.
I can do all the programing on a Tiny25 in C or C++ with no problem, but can not make the Tiny5 do its thing.
A very simple 10+ line C program to use as a hard reset device to wake up stubborn SSD1306 128x32 OLED.
Can some one help? Can I hire someone to work this project out for me? Can someone build a programming setup to do this? I am stuck and cannot finish my new product without this, so I would be grateful for help or for hire to do this. Thanks, Ray

I've had limited success with the ATtiny10 myself, but did run into one poorly-documented detail: they only program when powered at 5V. They can run at lower voltages, but won't program at 3.3V or 3.7V.
