No, SW V2 has nothing in it. I created it at Bob's request, but then we decided it would all work easier and better to make a branch of the first one. My code is branch WB1FJ_Port_to_Blinky. It looks like Chris merged something with main, but I'm not sure what. However, until a couple days ago at least, main was still the launchpad version. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Tue, Feb 27, 2024 at 9:22 AM Jim McCullers via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > > > I received my board last night and got it unpacked and started the visual > review process, as in, that’s where that is. > > I’ll get it over to the software station tonight and start the learning > process. > > My assumption is Burns V2 github version is the correct one to use. > > > > Looking at the schematic, there may be a possible problem in the receiver > front end but I need to review the AX5043 documentation and schematic > before testing. > > > > 73 > > > > Jim > > WA4CWI > > > > Initially there is an issue hearing a signal.

I received my board last night and got it unpacked and started the visual review process, as in, that’s where that is. I’ll get it over to the software station tonight and start the learning process. My assumption is Burns V2 github version is the correct one to use. Looking at the schematic, there may be a possible problem in the receiver front end but I need to review the AX5043 documentation and schematic before testing. 73 Jim WA4CWI Initially there is an issue hearing a signal. RX Device 0 and 1 have no RSSI even if a strong signal is transmitted on their receive frequency RX Devices 2 and 3 both show an RSSI change with a transmitted signal. I'll try to see if one of them can trigger the interrupt line. Initial testing suggests they do not. 73 Chris On Mon, Feb 26, 2024 at 9:05 PM Bob Stricklin via pacsat-dev <pacsat-dev(a)amsat.org <mailto:pacsat-dev@amsat.org> > wrote: I just checked a board and I see the RX3 sitting at GND state.

Initially there is an issue hearing a signal. RX Device 0 and 1 have no RSSI even if a strong signal is transmitted on their receive frequency. RX Devices 2 and 3 both show an RSSI change with a transmitted signal. I'll try to see if one of them can trigger the interrupt line. Initial testing suggests they do not. 73 Chris On Mon, Feb 26, 2024 at 9:05 PM Bob Stricklin via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > I just checked a board and I see the RX3 sitting at GND state.

I just checked a board and I see the RX3 sitting at GND state. Assuming the TMS570 is programmed to be an input the AX5043 must be pulling this line down to a low state. The IRQ line is pin 19 and they all have a via close by that you could scratch the solder mask off of and measure the voltage. If they are programed correctly and receive data this line should go high and stay there until the buffer is cleared.

We know that interrupts work on both the Launchpad board and the RTIHU, so if they and Blinky are all wired the same way, we should be good there.

The AX5043 has a 65K pull-up on the IRQ line. It interrupts by taking this line to a high state. The data sheet dose not say this but the output must be driven low when not in IRQ state. Seems like a odd way to do this so I may be reading it wrong. Output lines are supposed to support up to 40 mA. So you could probably cause an interrupt by using a 1K resistor with a jumper on it. Connect the jumper to 3.3V (Tab of the big regulator standing up and bent over) and tap the other end of the resistor on the IRQ line. You should get a single pulse and not damage anything.

It could be hardware or software. To help sort out issues with the AX5043 I have made up a table (attached) to correlate the Select, IRQ lines with the physical chip on the board. All four AX5043s should have an RX signal so in theory any one of them could be used to receive signals. However there could be a hardware issue with any of them.
