Hi, i want to know how i can access pb3 reset pin of attiny44 IC. I ran out of pins so i am using it as I/O pin but i am unable to declare it in the code.
The RESET pin of attiny cannot be used as an Arduino pin unless the internal fuses are changed to allow it. Once that fuse has been changed, ISP programming can no longer be used, because for ISP programming, the RESET pin must be in its original mode. The only way to change the fuse back is, I think, to use a "high voltage programmer" which is a specialist and expensive programmer.
However, it is possible to change the fuse and install a bootloader which allows the chip to be programmed over USB. This is how Digispark boards work.
Manipulation is because int led=11; does not work.
yes i am using damellis.
Is there any way to declare in this one because i am afraid spence would take time to install, i have to do alot of research before i can do it.
OK, i am using arduino platform for writing code and then i use HVP in order to turn my reset pin into GPIO. Just now i made a test using atmel studio (the pin declaration as PB3 and it worked perfectly) but in arduino IDE it does not work.I believe that there is some issue with library file, let me try spencekonde core package as you have mentioned.
see it does show 8MHZ but it does not upload to IC, i checked with my HVP(high voltage programmer)
It shows me (CKSEL 3-0= 0000 external clock).
Same issue is there with 16mhz, i believe there is some other issue.
The hell? You're saying that crystals don't work on the r84 at 8 MHz on v 1.5.2? That version has been out for over a year and nobody has reported anything about it.
Note that there are two options - external CLOCK and external CRYSTAL.
Also 1.5.2 - i just checked - doesn't have the external clock options. So you're using the head from github which is 2.0.0 beta. it looks to me like that's the menu from the 2.0.0, where I use scripts to generate all the clock options for all parts. But looking at the file it should be setting the low fuses to 0xFF if you select the external crystal option (but 0xE0 if you set it to external CLOCK, which is what you seem to be selecting in the screenshot)
