Hi everyone,

I have switched to a new processor chip for the SeaTalk Nmea Bridge.

Currently we have an ATMega32 - which has 32 kb memory.

In the future I will make a bridge available, that uses an ATMega1284p processor. This chip has 128 kb program memory and also a little bit more RAM memory.

That gives us more space to implement new functions.

For example, I have enabled the 'big-digit display' for SOG, which was not available in the past due to memory limitation on the old processor. .

Next things will be - calcualtion of true wind heading/speed from apparent wind heading/speed and speed through water or speed over ground.

A first software version for this new chip is running in the lab.

I also have switched software development from linux to Windows with AvrStudio 4. This software will be available as a AvrStudio project.

Anyone interested to get a peliminary software release for testing and/or programming ?
If yes - just send me a mail and I'll send you the AvrStudio project.

I can also send pre-programmed processors if you should have problems getting the chip.
The chip used is a ATMEGA 1284P-PU PDIP-40.

All right - I have sent a first testversion to a user/developer.
I'm eagerly awating responses. Hope everything works as it should.

A first version for calculation of true wind direction & speed is also included.
It takes apparent windspeed and direction and boat speed and calcualtes true wind direction and speed from this.
Also eagerly awating responses. Smile
