Launchpad Rev 1.4 RXD TXD jumpers ?

[sirri 28]

Hello,

I am using 2553 microchip using Launchpad Rev 1.4

According to https://github.com/energia/Energia/wiki/Hardware

I have to cross the jumpers (check the image please) in order to use Serial Communication. How will i do that (without soldering)? Any idea?

Thanks,

You can do it with 2 female to female jumper wires. I soldered wires across 2 lots of 2 female headers making a 2x2 block with wires soldered across. This is neat and unobtrusive.

 

The only non solder job I can think of though is 2 crossed f2f jumper wires.

 

Have a great Christmas.

Thank you very much DanandDusty. I don't have those female-to-female wires but i am planning to buy some female-to-female and male-to-male packs..

Merry Christmas ; )

Take four jumpers that have open tops instead of closed ones. Place them so that each is on a single pin. Then use some spare cable and stick it into the free side of each one, crossing them over. Like little headers. 

 

 

Or if you soldered on the female headers on your r1.4, then you only need the 2 jumpers. I used 24awg wire, 23awg would fit better.

thank you. but your launchpad is already a rev 1.5 right?

It looks like a 1.5, but the concept should work for yours as well

Three of four at r1.5. The r1.4 is currently being used, so I couldn't do it with that (I got female headers on that one anyway.) But yea, the concept works for both boards, and really, for anything where you need to turn a male header into a female one. I use it for the p1.6 led jumper, since the usi i2c uses p1.6, I have to disconnect the jumper for it to work, yet I use some this trick to have another pin toggle that led.

I too have a rev 1.4 Launchpad upgraded with an m430g2553 and have created an X jumper for the RXD TXD.  I have tried several of the example sketches in Energia but I am not getting any data back from the Launchpad in the serial console.

 

Any help would be greatly appreciated.

crossing jumpers on the 1.5 would change it in a double loopback, wouldn't it?

So the MSP430 RX and TX are connected to eachother and the USB RX and TX to eachother as well.
