New to Avr + Zigbee (ATMEGA2564RFR2)
Hi,   I am just curious about a few simple questions. I tried reading about ATMEGA2564RFR2 (the 8bit zigbit chip). My simple goal right now is to locate a zigbit chip,...

Super Simple Soft Serial Write
I know I saw somewhere a super simple Software Serial. Along the lines of put char to output PD7 (AIN7) for my case. sleep, write next char. I can't find it, does anyone know the...

Output voltage from avr pin
If I supply a voltage to my chip (atmega328p) of 4.1v the output I had expected the pin out (ie:PC0) to be in that range. Instead I measured it as 1.6v. I have made a horrible...

UART fgets, but with timeout?
I am looking to write to a chip, and I always expect a response, but if the chip is off (or broken) I want to not hang waiting forever. My code has both a regular polling version...

from Tiny to Mega
Just curious, I was thinking of going from my Tiny4313 to a Mega8PA for the space. Should I expect major code differences? Mostly logic, except UART, and delays. I would hope no...

Check if I am reading pin correctly. (Solved)
I know its not all the code, I just want to make sure if I supply +V to Pin B2 on my attiny4313 this should read "1" (or rather 4, point being not 0). Sadly I only get "0" back (...

uart works with delay? (CLOSED)
CLOSED I have an attiny2313a communicating to a gprs chip (sim900). The sim900 is streaming data pausing for a second or so between a data burst. Quote: write_string("AT+CENG...

itoa atoi
write_string(buffer); write_char('='); write_string(itoa(atoi(buffer),NULL,10)); This leads to: Quote:0136=3136 Why isn't it 136, why is it 3136? Note: I did post a more...

How much ram
Based off of someone's recent post of an ISR collecting usart information, I realized I might run into a ram issue.... Remember I am new to this. I probably will get a response...

Tips on how to communicate with other chips
Specifically UART. I am going to be communicating with another chip, but as I program I want to make debugging easy. I want to know what I received from the chip. Now my chip (...

Soft UART on ATTiny2313a
I am trying to find a soft uart for my attiny2313a, so that I can use my usart to communicate to a chip and communicate from my terminal. (ie: daisy chain computer to avr to chip...
