Multiple serial communication

Hello all!

Is there a way to communicate between a atmega328 and the Z-UNO? The TX&RX pin on the mega is already in use. maybe possible to use I2c?

LoRa SX1278

Hello,

Do Z-Uno support SX1278? I can not find that many guides on google, but some of the once I do uses library...

Have anyone used this module with the Z-uno?

I don't know if this exist, but I use 15 pin PCB socket.

Re: avr/interrupt.h missing

Thank you, I will read what you said in detail when I get home and try to figurer all this out :) My project is kinda simple, I've just over complicated it out of this world! Basically it notifies me of mail in my mailbox. I live in an apartment and there is 50-60 meters to the mailbox with walls. A...

Re: avr/interrupt.h missing

Am I understanding the example right, when the Z-uno sends the number 1 to the UNO, the led turns on? In that case it actually looks simple! Well, it looks more complicated than the example I found, but I guess I can work with this! In my schematic I shared the RX/TX line from the HC-12, sent it to ...

Re: avr/interrupt.h missing

I am not skilled enough to do that :P


But no worries, I am making the circuit myself, so I'll just add a ATTINY85 to do the serial comm. and then give the Z-uno inputs and outputs :) I know it is overkill and somehow dumb, but it's the way I know how to do it :lol:

avr/interrupt.h missing

Hello, I am trying to use a code that compiled fine on the ATTINY, but not on the Z-uno.. When verifying it sais interrupt.h is missing. I am using the library SoftwareSerial.h Also, if I upload something that dont use this library it works. So I am guessing the library is the problem. I've also add...

Re: RTC or Day timer

That was actually quite smart. I have never thought about that. Converting millis to hours and then use hours instead of an very long line of ms!

Re: RTC or Day timer

I usually try to use standalone chips, and I have a sender and a receiver now. ATMEGA328 and at the receiver I use the z-uno and HC-12 modules between. I read that the ATMEGA chip does not have a good clock, so it will miss "steps" every day... I do not need any precise measure of time. I just want ...

RTC or Day timer

Hello :) I want to include a timer in my project to make something happen once a day. I have read the RTC in these microcontrollers are not great. But I belive that problem disappears if you include a 16 GHz crystal? I then need the crystal and two caps. Is it correct that they will be connected on ...
