I’m sorry to have absent for a while, but it was for health reasons. Returning to the subject AS3935, the prototype is working since I rode the SPI mode and I2C. The dificíl was wait for lightning. I sent an email to AMS talking about the lightning emulator and the answer came with a NDA, schematics and code (hex) of project using PIC24FJ16GA002, did the assembly and recorded in the arquivo.hex in PIC24FJ and was very good … I can now emulate a lightning 5km, 10km, even a disturbance or an “Storm overhead”, ie giving to emulate and adjust the AS3935 using LCD NOKIA 5100.

Right now the chip is telling me that there are lightnings all around me. I´m not sure about that result but I´m glad that there is more than “lightning out of range”.
This should be solved by modifying some registers.

I wish you continuing success with the chip.

Now that I can reliably talk to the chip, I am finding that during storms I never get strike alarms just disturbers and noise. I have a series of technical questions I sent to AMS that I have not received answers on yet. I think I will learn what I could do to make my system more sensitive and possibly yours less. This will likely be to change the front end gain and the threshold register values. But how I am not sure.

Stay tuned and I will be sure to post my findings.

Your english is much better than my German!

it seems you know lots about the chip AS3935.
Maybe you have an idea to a tiny problem in the context of my chip.
Till now there´s no problem to write or read the register of the chip, antenna tuning and clock generation works fine. The rest of the registers stay on default values.
My problem is that the value of the REG0x03[3:0] is nearly always 0001 (which stands for noise level too high).
Occasionally this value is zero, but the register of the distance estimation is always 0x3F, althougt there are values in “Energy of the Single Lightning” REG0x04 | 05 and so on..(I´m glad to have an lightning emulator to test lightnings ;) )

So I´m wondering if the problem is because I forgot to set any important value at any register -any software problem- or could it be possible that my board is wrong connected (I did it by myself so it´s really possible..) or the LC resonator is not correct, althougt the antenna tuning works fine -hardware problem-?

Thanks in advanced, it´s great that you share your experience with others!
(Sorry about my bad english)

Cheers Gina

So an address of 3 (0011b) needs to be shifted up a bit to make room for the read/write bit. The address defined in the as3935.h file is an “8 bit address” and should be entered as (0×03<<1) or 0x0E. I hope this helps.

i ran a I2C address scanner and located the as3935 at address 0×03.
that said i located a spot in your library, as3935.h that sets the address to 0×00. i changed that to 0×03 and still get the above read on serial monitor. curiously i pulled the pins A4 ans A5 and restarted striker. same readout. it is as if i am missing a minor detail in the addressing. my board is definitely address 0×03.
did i miss your scheme for setting the base address for the board?

i’ll let you know.

i have 5 v, gnd, irq to D2, SDA to 4 w 2.2k to 5 volt, and SCL to 5 with 2.2 k to 5 v.
CS and MISO left open.

no further help on this compile issue is anticipated.
thanks so much again and again.
you have a favorite fan.
Dave
