Wise Clock 4 with ATmega1284

I thought that replacing the ATmega644P with its bigger brother ATmega1284P in Wise Clock 4 would be trivial. How wrong I was. The first step was to burn the bootloader. After a bit of research, here is what I found out: USBtinyISP from adafruit cannot program chips with more than 64K of flash (see this thread ); if you don't want to start from scratch (that is, compile the source code and figuring the fuses) there are at least 3 sources: ryanmsutton , maniacbug and calunium ; USBtinyISP half-works: it writes to the flash, but reading back for verification purpose fails because of a bug in the firmware; I ignored the verification error; although burning the bootloader (any of the three mentioned above) seemed successful, uploading any sketch afterwards always failed; the setup from ryanmsutton did not work for me (I guess the fuses are wrong; then the core files also point to the arduino folder, instead of the sanguino, as it should be); with the bootloader from...

Troubleshooting guide for Wise Clock 3/4

This should really be a chapter of the assembling instructions for Wise Clock 3/4 . Until I integrate everything into a single document, it is just another post that begged to be written (long ago, as a matter of fact). 1. Right after power up, the clock should make a beeping sound. If that does not happen, here are possible causes: missing input 5V power; the optional power LED may be useful in this case, turned on when the power is present; reset pin may be shorted to ground (the processor won't execute any code); processor may not be powered: check that pin 10 has 5V and pin 11 is connected to ground; faulty or missing the 16MHz clock for the processor; check crystal connections to the pins; if everything looks good electrically, try to upload a sketch; it that still doesn't work, test by replacing the processor or replacing the crystal; buzzer may be disconnected; check connections between processor's pins and buzzer, shorts to the ground, terminal soldering. 2. The di...

Stand for ClockTHREE

Image
Some time ago I received, as a gift, this smart and very useful stand from fellow clock enthusiast Nicholas in San Diego. He designed it and made it specifically for ClockTHREE . Simple yet elegant, this is essential if you want your C3 on the desk or table. I did not have the chance to appreciate it until now, with an older  ClockTHREE  borrowed from a friend (I gave it to him as a gift). Here is the C3 on the stand, a perfect fit! Thank you Nicholas! Keep up the great work!

Wise Clock 4 - "Time Lived" menu option

Image
At the request of AlexT, I implemented a new feature in Wise Clock 4 , which allows the display of time lived (since birth) in different formats (years/months/days/hours/minutes/seconds, days only, hours only, minutes only). The above photo shows the year/month/day on the top row and the hours/minutes/seconds on the bottom row. Lifetime in Wise Clock 4 from florinc on Vimeo . The birth date and time are read from the file message.txt on the SD card. I was inclined to use the Time library, but I found it a little bulky for my needs and also unsuitable for dates before 1970. Then, I copied and modified the function makeTime() to convert a datetime to seconds, and I wrote my own diffTime() function to calculate the difference (in years, months, days etc) between two dates. Alternating between display modes is done by pressing the SET (middle) button. This code will be included in the next release of Wise Clock 4 software.
