Hello,

Are there any plans about a new batch of sensors?

Regards,
Dmitry.

Hi,

It seems that raw data export has trouble now.

I see some PHP code instead of the data when I access http://radioactiveathome.org/boinc/gettrickledata.php

Could someone check please?

Hi,

Are the sources for 1.78 available?

Szopler,

What about EEPROM? where can I find a hex file for EEPROM?

I programmed my atmega88 with the \Release\Radioactive_V2.60.hex via ISP
and now I got one "?" having my LCD disconnected

What does it mean? What shall I check next?

(Previously I got nothing at rs232 as my usb-to-rs232 converter was broken)

I'm little confused with reading RS232.

How should I connect 1,2,3,4 holes at the PCB with the 9-pin RS232



I connect
[PCB hole <- pin name at the pic]
2 <- TD
3 <- RD
4 <- Signal GND

and leave hole 1 unconnected (as the PCB is powered by MiniUSB connector)

Is my connection right?

With this connection I read the Serial port but nothing comes from the sensor when I attach MiniUSB to the PCB to supply with power.

I've checked the fuses of the atmega and its efuse seems to be wrong (0x04 instead of 0xFC).

Can it cause the problem?

For some reason update of EFUSE fails.

Shell I try to update the program?
How can I do it?

Can I just do
avrdude -c arduino -P COM3 -p m88 -b 19200 -U flash:w:Release\Radioactive_V2.60.hex
?
(where Release\Radioactive_V2.60.hex is the content of the "firmware sources" zip)

Shell I try to update the bootloader? Do I need it?
Szopler, could you advice where can I get the .hex file with the bootloader?

Regards,
Dmitry.

Hi,

I've assembled first sensor. But it does not work.
Could you please advice how to debug it?

When I plug it in the buzzer beeps shortly and LCD shows blank symbols.



Nothing else happens. PC doesn't show any connected USB devices.

I measure 5V at 7(VCC) and 8(GRD) pins of the controller,
but 0 Volts at C9.
0V is also at c10 and c13.

What are the proper steps to debug it?

Shall I try to read RS232? What will it give me? Presence of I2C data exchange?

I have standard multimiter. What are the key points to check at the PCB?

Hi,

How could you resolve the I²C address issue?
Did you reprogrammed the controller?
I've ordered an arduino LCD expander and expect the same problem.

Just FYI.

As I have impediments finding some of the parts I desided to check how many detectors have been assembled.

Only 33 sensors (v2.60) have ever sent measurents out of 200.



Not so many...
