I know this may seems extreme, but sometimes the USBASP is not wired to supply +5V power fo the AVR... I see you don't have any external 5V to that protoboard on the first picture...

I see you have a folder with name "AVRDUDESS".... this is the folder from the graphic interface for AVRDUDE. If yes, launch AVRDUDESS and set interface clock low, lower than...

tinyAVR DAC Tone Generator on Slow Clock Speed
Perhaps you can generate the 2kHz sinewave you want with only 100Hz clock to the AVR. It is so simple to build a 2kHz sine oscillator with two transistors or op-amps, and the...

Miniature Speaker and ATMEGA
Based on my 1970ish calculations of speaker boxes we use to make with tick marine plywood, and concept of power transfer, to achieve the best possible power transfer, the...

Different working speeds at the same baud rate
One common way used many years ago, even on mechanical machines, when no packet CRC was used, was to echo back the received character.  The sender would only transmit...

Different working speeds at the same baud rate
115kbps is the speed the chip is serializing the data out, it doesn't mean "all the time".   Even the USB-UART may talk to the chip at that speed, but the speed it...

Are general purpose/IO reg and Data memory created using a single SRAM?
Yes, even that the following in fact copy R16, R17 and R18 into R0, R1 and R2, because the first 32 SRAM addresses gate the data to the GPRegs, it doesn't need to have a dual...
