Attiny85 problem? #7

Closed lazlyhu closed 6 years ago

lazlyhu commented 6 years ago

Hi!

Thank you for your work, I really like it, just working. :) I have some change, I'm planning to share here but first I wanted to finish my project.

I'm ready with my project (in software side) and made a PCB for finalise it in an Attiny85. In probe panel with Arduino (be exact, on the receiver side an Arduino Nano clone) everything worked great, I attached the the RX radio to pin2, working great. Because Pin2 in Arduino is INT0 I decided to use the INT0 in Attiny too, so used PB1. After the PCB went ready I recognised my mistake, because PB1 is INT0 only in attiny13, in Attiny85 I should use PB2. PB2 was free, so now I connected it to PB1.

Anyway, my issue looks like because some reason It's not working on any port (PB1 or PB2). Do you have any idea why? I complied with DIY AtTiny, and first write out the bootloader to setup the fuses. Maybe some fuse settings failed?

Thank you, wish the best!

Looks like should an issue around PinChangeInterruptHandler lib, or I missed something in that part of the code. I wrote two example sketch. The first working, the second don't. What do you think?

I don't have any idea what's wrong with PinChangeInterruptHandler but there should be some issue. I really want start using the result of my product, so I rewrite RFReceiver out of PinChangeInterruptHandler based on this idea:

Base steps:

Practically you don't need receiver.begin(); anymore, don't need to call
But in setup() you should call something like: attachInterrupt(digitalPinToInterrupt(SIGNAL_PIN), interupt, CHANGE);
And define somewhere a simple target of the interrupt: void interupt() { receiver.handlePCInterrupt(); }
Refactor the RFReceiver to recive receiver.handlePCInterrupt(); as a public call without any argument, drop the included PinChangeInterruptHandler, etc

I know, It's not solve the problem. Maybe if you have time feel free to reopen the issue and I would be happy to help you find some real solution. But I left here, maybe years later somebody looking some fast solution too. 😀

Hi @lazlyhu,

I am sorry that I didn't respond to your issue. I am currently extremely busy at work. I have an Attiny85 in my junkbox. I will try to reproduce the issue this weekend.
