New VLF with double MCU and 2.4" touch screen

[reptooyep]

Hi to all,
I've just finished my new project board.
The detector is mostly inspired from quasar shematic for the TX and RX circuitery but with a ATMEGA328P.
The second MCU (the same) is used for HMI interface (TFT and touch screen + Battery indication).
The first MCU will be clocked by a 16MHZ quartz and the second with the external clock from the other.
The TFT board is a 2.4 TFT LCD shield for ARDUINO with a SD port, so, you could have a cool display with pictures.
I know how to program AVRs with ATMEL studio or ARDUINO but it'll take months to make it work cause phase measurement function will be hard to implement for me...
That's my board (lay6 file).

Nice idea, just cannot imagine situation on the field with that touchscreen and my hand's with mud on a rainy day's.
Nothing wrong, just my little opinion.

Like my dog, i prefere not going out when it rains
Maybe i should add a tuning button ?
The touch is resistive so, you could use it with a stylus.

It's not just the mud and the rain. Most people wear protective gloves when searching.
You will need special gloves to control your touch screen in a reliable way.

Someone knows a project (VLF or IB) with open sorcecode? I Wang to have a look at the Software implementation.

hello reptooyep,

are files for diy available for others, or just for your own?
working hex file would be ok

Funnily I was thinking about 2x MCU when I saw two DD coils in the same housing. Not that its needed as you would have to switch one coil off to sample with the other.

Hi,
I just did the pcb file and i'm improving it before ecthing.
The soft is not implemented yet but i think i'll start working on during jully.
EVERYTHING will be open-source cause tha's the goal of a forum, i think.
If someone wants to make money with that, i'm agree with it, i don't care about money, i just care about DIY stuffs.
I think i'll start workink on the softs with arduino cause the library is available for the touch screen.
The only obscure part of the job is for programmi.ng the two MCU. I'll try to burn the fuses for external quartz for the first and external clock for the second but i don't know if i'll be able to promram the second one with different fuses configuration.
I've already programm a standalone AVR with ARDUINO IDE but only with a quartz, not with external clock. But i think it should work
