LaunchPad Pin Assignment

Thanks Rei Vilo !

Like your visual presentation.

Rick, thank you for the pins number.

 

It seems that Energia has defined P2.0 for CS and UCBA isn't implemented:

 

/**
* File: usci_spi.c - msp430 USCI SPI implementation
*/

/**
* spi_initialize() - Configure USCI UCB0 for SPI mode
*
* P2.0 - CS (active low)
* P1.5 - SCLK
* P1.6 - MISO aka SOMI
* P1.7 - MOSI aka SIMO
*
*/

Please comment this schematic guide to use Energia with the LaunchPad v.1.5 an the MSP430G2553.

Is there enough space to show the wiring connections to J3? It would be nice to especially have the connection to the TX and RX J3 pins and show how the position of the jumpers changes the MSP430 connections.

Very nice work, Rei!

I'll base my first version of the HW reference on your work, it's exactly what i imagined

Note: MOSI and MISO are flipped on the USI chips. (g2231/g2452)

Nice work.

And here comes the same schematics for the 2452:

That looks awesome Rei! Let's get this posted on the https://github.com/energia/Energia/wiki/Hardware page.

Good work Rei.

Consider the use of the label "TimerSerial" instead of "UART" in the MSP430G2452 reference chart.

Confused with LaunchPad MSP430 pins :?:

 

Find the schematics for MSP430G2553 and MSP430G2452 based on Energia implementation :arrow: here and also :arrow: there!

These images are great. Nice job. ... My only concern is that people with a version 1.4 board or older will fry their chips. On those boards the first two jumpers are are VCC (3.5volts) and TX. Turning those jumpers sideways could potentially cook the pin. Maybe a disclaimer is in order. If you have a 1.4 board, don't ever turn your first two jumpers 90 degrees.

[energia 485]

Good point! I suggest that we display them in a "save factory default position" and put a big fat circle around it pointing to a foot note explaining all the other positions and when they apply.

[Rei Vilo 695]

Something like that for a MSP430G2553 on LaunchPad v1_4?

The cross connections needs to move on jumper to the right to cross TXD and RXD.

Thank you for the feed-back.
