Pin Names - Connected Launchpad

Recommended Posts

It would be nice to have the pins that are connected by a shunt noted on the diagrams for the Connected Launchpad.

 

 pins PQ2 and PA3

 pins PQ3 and PA2

 

A reminder about R19 and R20 would be particularly helpful on the X11 connector diagram (since both sets of pins are brought out there).

Yes and no.

 

Yes, R19 and R20 perform the same trick for pins PQ2 / PA3 and PQ3 / PA2 on the TM4C129 as R9 and R10 do for pins PD0 / PB6 and PD1 / PB7 on the TM4C123. 

 

No, as I²C port 8 isn't implemented in Energia and pins PQ2 and PQ3 aren't available on the BoosterPack pins of the TM4C129, whilst all the pins PD0 / PB6 and PD1 / PB7 were available on the TM4C213 and thus prompted confusion.

 

So I'm updating the X11 pins map solely.

 

Now, would you mind filling a ticket at http://github.com/energia/Energia/issues for adding support for the missing I²C ports?

Hallo,

 

Thank you for providing us with pinout map links/files in this post.

 

While trying with Energia 0012 to get Sharp® LCD BoosterPack (430BOOST-SHARP96) working with EK-TM4C1294XL Connected Launchpad with no success so far (NOT PLUGGED IN BUT CONNECTED INDIVIDUALLY TO PINS - SSI module 2 is probably the default in Energia) I found different assignement of pins 14 and 15 (MISO and MOSI) compared to TI document provided in the box with LP - spmz858.pdf - and other TI docs including SSI2Tx and SSI2Rx. PD1 and PD0 correspond.

 

TI:

15 - PD1 SSI2Tx - MOSI

14 - PD0 SSI2Rx - MISO

 

Energia (RV):

15 - PD1 - MISO(2)

14 - PD0 - MOSI(2)

 

Please clarify or expalin to me (I am still learning).

 

Thank you.

Pavel

 

Thanks for the notice.

 

That's a difficult question, as the Energia implementation for SPI refers to the pins as GPIO_PD1_SSI2XDAT0, GPIO_PD0_SSI2XDAT1 and no longer GPIO_PB6_SSI2RX, GPIO_PB7_SSI2TX.

 

The explanation is the TM4C129 is capable of QPI, so no more MISO MOSI but 4 parallel bi-directional lines for fast reading-writing. But QPI hasn't been implemented yet in Energia release 12.

 

I'll proceed with the required tests and update the pins map.

 

As a matter of facts, I haven't had time enough to really play with this board. 

 

Either drawing pins maps or playing with the Connected LaunchPad: what do you recommend?

Rei,

 

I appritiate your job and contribution. I did not ment to give you more work and hope you will have an opportunity to play with the board enough and also generate so valuable outputs.

 

Thank you.
