Apparently what I have does not exist anymore, but this is very similar and I'd be shocked if it did not work with Jim's PacSat simulator. https://www.amazon.com/Serial-Adapter-Signal-FT232RL-Windows/dp/B08BLHGWHS 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

Pacsat main updated
by Chris Thompson 13 Jun '23

13 Jun '23

I merged version 0.1c into main. This has a few bug fixes to the AX25 data link state machine and cleans up a few things. I am going to take a break from working on the uplink/downlink and catalog all the TODO items that I noted as I worked on the code. They are mostly to do with error cases. I'll make a list of what needs to be worked on and how that will fit with logging errors and the telemetry we need to store/send. The AX25 connection needs a thorough test if anyone has time to work on that. Let me know if you find issues or log them on github. 73 Chris -- Chris E.

Small software update
by Burns Fisher (AMSAT) 10 Jun '23

10 Jun '23

I updated the pacsat software to print something more reasonable about the MRAM size. (What I described to Bill was really not right...I simply had not previously indicated what I was displaying!) The version number is also updated to V0.1b (from a). Please remember to update this when you push changes to the repository so we can keep track of what we are using. (I think there are really a number of different versions all labelled V01.a---if you get b it will be the latest as of today). 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

It's not the whole MRAM. -corey > > ----------------------------------------------------------- > > 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

The flash memory size could have been written as 1.25 megabytes, I suppose. It was just taking the size and dividing by 1 meg and then the remainder by 1 k. The MRAM line has not been updated since a) the file system was added and b) since Jim used those very small MRAMs for the test board. The structure size is the size of the "status info" structure that is not part of the file system, and that is correct (in bytes). The MRAM size is not correct--it assumed the smallest MRAM was 1M. Use "get mram size" to get the actual size. I'll fix that at some point. Thanks for noticing! I usually totally ignore the startup info :-) Pacsat>get mram size MRAM Address Size=2 Partition 0 size=292, partition 1=65244 MRAM0 size is 16KBytes, MRAM1 size is 16KBytes MRAM2 size is 16KBytes, MRAM3 size is 16KBytes Notice that "Partition 0 size=292" is decimal for 0x124, the number shown above. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Sat, Jun 10, 2023 at 11:06 AM Bill Reed via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > My sign in returns: > > AMSAT-NA PacSat Console > Flight Software X0.1a (built on Jun 10 2023 at 08:43:48) > Compiled *RELEASE* > **X, E, U, or DEBUG Version: Not configured for flight** > Watchdog NOT Enabled > Using FreeRTOS withOUT premption enabled; > Free heap size is 55944 > Flash memory size 1Mb+256Kb; MRAM size is 0x124, structure size is 0x124 > > > Free heap size after tasks launched: 19056 > *** NO RTC: SET THE UNIX TIME BEFORE UPLOADING ANY TEST FILES *** > Starting RX with AX5043Device 0, vhf=1 9600bps=0, freq=145835000 > Starting TX with AX5043Device 1, vhf=0 9600bps=0, freq=435760000 > Pacsat> > > What does this line mean? > Flash memory size 1Mb+256Kb; MRAM size is 0x124, structure size is 0x124 > > > ----------------------------------------------------------- > > 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 >
