I would like to ask do I need to add an external 16MHz crystal or what clock source been configured for the fresh attiny 85 ?
Besides, how can I program it using the arduino IDE ?
Is it I need a USBasp and connect the MOSI, MISO SCK and RESET besides the VCC and GND ?
If I use external crystal because I want to use it at 16MHz, then it means I lost 2 IO pins ?
How do I configure the attiny 85 to use internal 16MHz crystal ?
By the way, can I confgure the atmega 328 to use internal 16Mhz oscillator too ?
I thought atmega 328 just can have 1MHz internal
* Open the "boards.txt" file and change both of the "upload.using" entries to the appropriate value for your setup. Following from the examples above, the file would be here... C:\Projects\Arduino\hardware\tiny\boards.txt* Start the Arduino IDE and ensure there are two new boards listed under the [Tools] [Board] menu... "ATtiny84 @ 8 MHz" "ATtiny84 @ 1 MHz"You are now ready to use Arduino-Tiny!What does the bolded part means ?I did not do that. And my tools > board now not only contain the 2 new board, but also some others like what you mention(ATtiny85 @ 16 MHz (internal PLL; 4.3 V BOD) board)
What does the bolded part means ?
I did not do that.
And some of my board type has gone missing
