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?

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.

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.

Glad to hear this is working. I have noticed one thing with version X0.1e. When you press the reset button on the launchpad it pauses for about a second before printing to the console. Is that an intentional change to the boot process? Otherwise we should investigate what changed. 73 Chris On Sat, Aug 5, 2023 at 5:26 PM Bill Reed via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > The MAX31725 SCL line had a zero ohm pullup.

That's where it went! Knew the inventory was off by one. Woops The MAX31725 SCL line had a zero ohm pullup.

I think I just had to clear MRAM. The garbage must have been some old data.
