Implementing an RTC in firmware via AVR 134
I need to add an RTC to one of my pcbs which has an Atmega328. I've read Quote:AVR134: Real Time Clock (RTC) using the Asynchronous Timer It looks like that will do what I need....

FatFs--Using bit bang instead of SPI module
The FatFs thread is getting really long, so while this is closely related I figured starting a new thread would be better. I have a card with an AtMega328 and working firmware to...

Servo speed, direction, and angle to move control
Several of my projects have pcbs that are using 2.4 Ghz communication with Nordic NRF24L01s. On one of the project pcbs, I want to add 3 RC servos. I'm a long time RC hobbyist,...

Sharing switch inputs with LED outputs--any downside?
So, I'm a little short on I/O on my ATTiny 24/44/84 RF remote project. It has six button inputs, three programming I/O (MOSI,MISO,SCK,RST), and two additional signals (CE and CSN...

How to stay in WDT interrupt mode and avoid system resets
The ATmega328P says this about the WDT: Quote:The first time-out in the Watchdog Timer will set WDIF. Executing the corresponding interrupt vector will clear WDIE and WDIF...
