Hi guys, I'm now working on a project were two devices have to communicate with each other. The devices are an Attiny85 and an Arduino UNO. It's crucial to me that they work at a same pace. When I was doing previous projects that consisted of an Attiny85 I ran it at 1Mhz since the timing was the closest to the Arduino UNO. I didn't select any other frequencies because they were way off timed. Plus the projects were simple, consisting of just few leds or servo's.
However, now I'm using a library that requires devices to run at least 8Mhz and when I upload a sketch to the Attiny85 using Arduino UNO as an ISCP and while clicking Tools > Board > Attiny85 @ 8MHz (internal oscillator; BOD disabled) the sketch starts to run incredibly slower.
Note: the board options are from an aditional library
For Example:
If I take a sketch that everybody is familiar with, which is the blink sketch that blinks the famous LED on pin 13 on Arduino boards once every two seconds and upload it to the Attiny85 selecting the 8Mhz option (obviously changing the led number 13 to a number from 0 to 4 which corresponds to the pins on the Attiny85). I get a LED blinker that dosent blink every two seconds but instead blinks every ˜10-15 seconds.
So obviously there is a problem with the configuration with the internal clock but I'm sure that I misconfigured something too.
I hope my point was clear. Help would be appreciated,
miXania.
