master branch will now work with 2 mrams as I said before. It also can
successfully talk to a serial line at 32k8 (and you really have to have
that to do anything useful) as well as an AX5043. I have managed to get
the 5043 to see a carrier on 2m (the RSSI goes way up) but not to get
it to decode anything or transmit anything. I may try that more, but
I'm not the 5043 expert by far!
talking with Jim McCullers, I converted all the connections to use
inner pins (Booster Pack connectors) rather than the outside pins. Here
are all the connections that the software is setup to use. You can also use the equivalent pins on the outside of the Launchpad (J10 and J11) but I wanted to make sure it would work with the inner pins.
(J2/3 means header J2, pin 3. Pins are counted from 1 on the USB connector end)
Power out (to MRAM and AX5043 board)
3.3V Output J2/1
Console serial line:
Gnd-J3/2 (Or any other --there are lots)
SPI1 (to both MRAMs):
Note that the common term for the data lines is MISO and MOSI. TI calls them SOMI and SIMO, the MRAMs just call them SO and SI.
NCS0: J9/3 (For MRAM 0)
NCS1: J9/8 (For MRAM 1)
SPI3 (for AX5043--probably for all if we have more than 1)
NCS1 J5/3 (Additional 5043s could use other NCS pins on SPI3.
IRQ goes to GIOB J8/8
hope I have all that right, but you can double check from the signal
names against the Launchpad data sheet). I attached a picture of my setup on a previous mail, but it is hung up waiting for Bill to release it.
