ATTINY85 in the IDE

Projects Programming

Does anyone have experience using the ATTINY85 with the IDE?? I am getting dozens of errors, just when compiling a simple code.

I am using one of the ATTINY example codes.

Errors:

Arduino: 1.8.19 (Windows 10), Board: "ATtiny25/45/85, ATtiny85, Internal 16 MHz"

What core are you using? I really like the ATTinyCore core. It will not solve all of your problems, but it will help.

There are differences in pins between the Nano an tiny85. Using the ATTinyCore, if you use serial, the default pins are RX = pin 1, TX = pin 0. ATTinyCore also implements I2C (Wire) and SPI in hardware. See ATTinyCore/ATtiny_x5.md at v2.0.0-devThis-is-the-head-submit-PRs-against-this · SpenceKonde/ATTinyCore · GitHub for pin assignments.

3

I know nothing about a core...
I've been following this.

4

Success!! It now successfully compiles!

5

A lot of those errors are because the core that you are using does not support the Wire library for I2C. The ATTinyCore does support the Wire library.

I am using this:

Should I get an external crystal, or use the internal one?

NOTE: This is my first time using an ATTINY chip, I'm a beginner with these chips!

7

It's been a couple of years, but I'm dragging one of mine out... I need a pwm generator...

I don't think the 'wire' library you are using is for the Tiny85...

Dug this up, see if it helps you out...

Good luck...

:smiley_cat:

8

Yes, @groundFungus's core suggestion solved the issue.

9

Do you need super accurate timing? If so, the crystal is necessary. If not, I have found the internal oscillator sufficient.

The only time that I used a crystal was for a timer for a clock. It did work very well.

Where is the 3.5V originating?

The is no 5V supply to the Tiny85 or is it off until you press the button?

If you are just measuring and displaying battery voltage and not using serial, I see no reason for great timing accuracy. The 8MHz or 16MHz internal clock should work well for you.

Here is the pin out for the tiny85 using the ATTinyCore showing the default pins for I2C (Wire).

The schematic does not show the required 0.1uF ceramic decoupling cap between Vcc and ground and the recommended 10K pullup resistor from reset to Vcc.

If you use less than 5V you may not be a able to use the 16MHz external or internal clock.

What is the 'A input' (PB3) being used for, PCINT3/XTAL1/CLKI/OC1B/ADC3 ?

How does your switch/battery circuit produce an 'analog output' and where does it go?

Into PB1? Which of these, MISO/DO/AIN1/OC0B/OC1A/PCINT1 are you trying to implement on PB1?

Suggest you put a an r/c network on the reset pin, other than just a pull-up. You want some minor delay so the micro won't reset if the power wobbles a little on power up... don't need much 100th of a second usually works, but a second wouldn't hurt it either. It gives you a long time for housekeeping if it's going down for power reasons. Should run without it...

I think this is pretty low power device, the datasheet states this for the internal 8mHz clock.. looks stable down to about 2V. Probably the same for an external rock...

How are you going to program this thing?

Do you have or have you built a programmer for these?

:smiley_cat:

That is to read the "internal" battery voltage (the battery powering the project).

It is reading the battery you are testing and then displaying that on an OLED screen. I'm using D0.

I'll be building this:

20

What I was driving at, which function of the pin are you using, PCINT3/XTAL1/CLKI/OC1B/ADC3?

I assume it's using ADC3 on PB3 ?

What is the purpose of monitoring the internal batter...?

How are you using D0 to test the battery? It will be one or zero...?

How will this tell you the 'test' battery voltage?

What kind of voltage range will the 'test' battery be?
