Attiyn2313 TinyDebugSerial @ 8Mhz #87

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Using TinyDebugSerial at any of the 3 baud rates
2. Output text 
3. @ 8Mhz
4. TX connect on Pin 4(documentation is missing pin number for 2313)

What is the expected output?
I should get clean text output via serial.

What do you see instead?
Garbled data only at 8mhz not at 1Mhz, which works.

What version of the product are you using? On what operating system?
Latest version 0017 with Windows 7 Ultimate x64

Please provide any additional information below.
The Attiny2313 works find at both speeds. 

I am using simple sketch. And blinking an LED works fine at 8Mhz

I didn't mention that this is with the 2313A and the 2313 works fine.

It turns out even though it worked on the 2313 and on the 2313A @ 1Mhz for 8Mhz 
I had to tune the resonator. I used TinyTuner2. 

Here is my forum post about it and it should help you tune. It requires another 
AVR to generate the pulse.

I am going to design an easier way to tune Attinys. It may be awhile but I will 
post it on friedcircuits.us.
