I sent this earlier, but just to Chris.

I got my board today and soldered on the connectors. Looking at the board now, I see that the connectors that came with the launchpad are around 1cm longer than the ones Jim supplied. I can't get the mram or ax5043s to be detected. I don't think it's making good contact on the connectors, for obvious reasons. Do I need to trim the old connector, or did I do something wrong?

I clipped the pins, and still no help. The power light by the serial connector works, and the serial port works. But the mrams and the ax5043's are not there.

I can't find the schematics in the git repository. PacSatDocs, I assume. I guess I need to start debugging to figure out what is wrong.

If you have received a PACSAT Booster Board from Jim, then here are some instructions for testing/using it.

First make sure you have followed Burns instructions to install the IDE and flash the launchpad. You know this has worked when you have the console up and can type commands. When it tells you to type a command in these instructions, it means on the PACSAT Console. You can type help to show a list of commands.

I suggest installing DireWolf on the same or another computer. You need to set it up to operate in full duplex at 9600bps. Initially you can use DireWolf to see you are receiving packets. Then you need to connect the ground station software by telling Pac Sat Ground that the TNC is connected to TCP port 8001, using the File > Settings screen.

In the console type:

send pb status

This will transmit a packet and it should say PB Empty in DireWolf.

Then type:

ls

This should show there are no files on the sat. If this does not work then type:

unmount fs

format fs

mount fs

In the console type:

make psf

This will create a set of test files

Type:

ls

To list them. We now need to set the time before we load them into the directory. We dont have a real time clock so it needs to be set manually.

Look up the current Unix time on the web. I use https://www.unixtimestamp.com/

Type:

set unix time <value>

Then you can type:

load dir

This will load the files into the directory and set their upload time. In the future PACSAT will load the directory at boot. Probably once we have a real time clock in place.

Type :

list dir

This will list all the files in the directory. Now when you reset the satellite the files will still be in the file system with the correct upload time, but the directory will be empty. You can type:

load dir

Without having to set the Unix Time, and it will load the files and remember their upload time.

In the Pacsat ground station you can press the DIR button if the PB is available, i.e. you are not already on the PB. If it thinks you are on the PB then you can type this on the console:

send pb status

If you press the DIR button it should request the directory and download all the headers. If you interrupt the download then subsequent requests will ask for the holes in the directory.

You can press the FILE button to download a file . Either type the file number you want in the box or click on the file in the directory to populate the box. You can also give a file a download priority by pressing numbers 1-9. See the manual for Details.

Feel free to ask any questions.
