Hi everyone, I want to program a few ATTINY841 using an arduino as ISP. Thing is that on the attiny there are multiple pins that can multiplex MOSI and MISO. Which pins should i use? Do you have a reference schematic?
Thank you very much.
Google it , many items on this
Hi, thank you for your reply. It seems tho that the example you provided Is about attiny84, which has some defined pins for SPI. On the other hand, if you take a look at attiny841 pinout, you'll see that MISO and MOSI can be multiplexed in more than one pin, so it is really important to use the "default ones" for programming. I'm betting that the default SPI pins are the same shared with te ATTINY84 pinout, but i was (and still am) not sure. Maybe someone already had the same problem and had a chance to test it.
Google again !!! This shows them Only in one place - try that .
(It’s not the most common of processors used with Arduino, all I’ve done is search on google ).
Probably worth going to Atmel and getting their data sheet too , which should have all the answers
