MrMobius: yes
MrMobius
bummer
i could use a 74 series chip to select between two lines but then i would lose any bytes coming in spontaneously on the other line
Spirilis
yeah
fwiw the FR5969 and similar e.g. the easier-to-solder FR5949 (TSSOP-38) should have two USCI_A's
MSP432 has four USCI_A's ...
alas none of the G2xxx series have more than one USCI_A nor more than one USCI_B
F5529 has two USCI_A and two USCI_B
USCI_A of course is the only one that does UART

MrMobius: are you using both uarts as input?

I tested out that nrf adatpter board this morning as they rx side of things and it worked perfectly, so no more rats nest of wires for my original that I had used for testing for so long....
It's nice to reduce the clutter...:)
Now I just need to test it out a bit more and see if I need to make any tweaks...otherwise I'm going to get a few more boards printed....as well as order more of the LDO chips that I apparently ran out of in building this last batch of boards..
Rickta59
nice glad it worked out for you voodoofish430
Spirilis
nice
voodoofish430
yeah, I looked at the code yesterday morning and found it would pretty much work with the board without any changes...so loaded it up and tested it out with a couple of tx's and boom...worked...
Now I can take the wired up one apart...
I just have the board and the max232 adapter...makes it so clean...
Rickta59
max232 for the pc connection?
voodoofish430
yep
Rickta59
heh .. i don't think any pc here have a real rs232 here
voodoofish430
I don't have any on my newest system. My old one was old enough to have one.
16550 or whatever it was...
Rickta59
that is your machine that acts like a dehumidifier?
voodoofish430
thats the one that sounds like a jet with the fans being so loud..
it was night and day when I got the new one...
Rickta59
i have a old 1u machine from the early 2000's that is like that
i think there is a 650MHz in there
maybe not even that fast
voodoofish430
mine was a 05 or 06....I forget what year it was...I kept doing little upgrades, more ram, video card...but it started lacking in....OOMF...
so upgraded....it lasted 8 years...so...
not bad for a PC's lifetime..

now there are phones more powerfull than your old PCs

99$ - 8 cores
4 times more cores than my laptop

"your old pcs", heck I started with a zx81 having 1k ram.
ike
there are now some intel CPUs with 128 MB of eDRAM L4 cache
where is your god now?!?
Amperture
Sanity check: The Programmer on the G2553 Launchpad is based on the EZ430-RF2500 (Since I tell mspdebug that's what the hardware is)
Thus, the device is programmed via Spy Bi-Wire
The FR5949 chip can be programmed via Spy Bi-Wire, according to SLAU367F.pdf
Also SLAU230T.pdf
Thus, I could potentially use the G2553 LP board to program an FR5959.
Am I getting out of hand anywhere in those assumptions?
voodoofish430
Sound like it might work.
ike
there is some crap about what chips supports Launchpad's firmware
supported chips have to be whitelisted
