Very peculiar LCD's pins behavior FlameSky wrote:if I'm trying to pull them down
Use of LCD is not just push/pull pins. It is a protocol between AVR and LCD processor.
You should talk in these terms...
ATtiny102, assembler, ADC problem Did you send anything else using USART, can you check your 'serialSend'. May I see the code of, please.

RFI from serial (UART) cable
Thanks for fine discussion, allow me to ask something else:
Admit that it is first time I see tantalum 10uf on such place. I will not ask 'Why NOBODY puts it', because...

RFI from serial (UART) cable
To young freaks: how 100++MHz noise is produced.
When current is switched, an electromagnetic wave is produced. Faster the switching is, more noise is emitted....

Solenoid coil failure detection What you need is a Non-Invasive Current Sensor.
It can be also any small transformer, add few turns of 0.5mm wire as a new Primary winding.

3 phase inverter for AC motor Not necessary, why it should be. Depends on what you will do with this sinusoide. After a Low pass filter, it can become a real one, but the ratio Max/Min will change.
Also...

Google ferrite choke rfi for more pictures.
How precise it should be? If you do not mind the difference, or you will increase the clock by OSCCAL (2% only), then it is for you: I do it often with M48, Timer1,...
