Small fix--Pacsat software x0.1f
by Burns Fisher (AMSAT) 07 Aug '23

07 Aug '23

I removed testing to see whether Golf i2c devices are there. They are not, and it makes boot slower and messes up the display for "get i2c". I also made "get i2c" more clear. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

Ignore it. The three ADCs are on Golf only, but at least one has the same address as the temp sensor, which is why it is showing up as true. I'm not sure why the temp sensor is showing up as false, but again, it is probably a screwup. I'll remove that stuff. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Mon, Aug 7, 2023 at 3:25 PM Bill Reed via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Any idea what this is telling us: > > Pacsat> > Pacsat>get i2c > I2c device state: > ICR ADC: 1 Solar ADC: 0, CSS ADC: 0 > RT-IHU Temp 0 > Pacsat> > > > ----------------------------------------------------------- > > pacsat-dev mailing list -- pacsat-dev(a)amsat.org > View archives of this mailing list at > https://mailman.amsat.org/hyperkitty/list/[email protected] > To unsubscribe send an email to pacsat-dev-leave(a)amsat.org > Manage all of your AMSAT-NA mailing list preferences at > https://mailman.amsat.org >

Re: RSSI reading
by Burns Fisher (AMSAT) 07 Aug '23

If you say "get rssi" it is read from the register right then and there. It looks like (need to ask Chris) it also checks the RSSI before it accepts a package, and in that case it also prints it out only moments after it took it. And it looks like it is only accepting (and printing) it if it is greater than 170 (raw value) which I think is -85dBm. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Mon, Aug 7, 2023 at 3:13 PM Bill Reed via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > When is the RSSI reading taken?

Re: Temp sensor

Are you sure it is 90 degrees and not the pure number 90. 90 is about correct for the numeric output, but then it should say something like (75F) after that. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Mon, Aug 7, 2023 at 10:11 AM Bill Reed via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > My temp sensor at get temp shows 90 degrees but my infrared thermometer > reads 79.

Re: Problem solved
by Burns Fisher (AMSAT) 07 Aug '23

07 Aug '23

The pause might be because the routine that polls I2c devices is working now, and since there is only one, they all time out. That routine could easily be changed to avoid polling devices we don't have. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Mon, Aug 7, 2023 at 8:51 AM Chris Thompson via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Glad to hear this is working. > > I have noticed one thing with version X0.1e.
