Boosterpacks compatibility (sensorhub + memory LCD boosterpack)

Hi Mario,

You need to see what pins are used in each booster pack, if they are different then they are compatible. If they are both I2C with different addresses then they are also compatible, SPI with different Slave select should also be compatible. I actually never used one myself.

 In the TivaWare there are examples for at least the I2C sensorhub, i think there is one example for the sharp LCD but it's for the FRAM MSP430.

Hi,

    It has just recent that the Booster Pack has been standardized and earlier versions of Booster Packs are not stackable to current Booster Packs that comply with that standard. You would need to re-wire it by means of protoboard or other means.

    From what I know the Sharp Memory LCD booster pack, is one of those that are not pin compatible to Tiva Launchpad booster pack pin outs

Thank you for your answer Kel. Could be another solution? What about the Nokia 5110. Or do you know another LCD that could be compatible with my purposes?

Best,

Since we are talking about compatibility, know that there are 2 pins shorted with a 0R resistor. I can't remember wich ones, Markel can you please confirm?

Mario, you should be able to use the LCD, the problem is that there isn't a available booster pack, you need to rewire the Sharp LCD, you can't just stack it. Here are some community boosterpacks:

I can't confirm which ones are compatible. But i'm guessing the I2C boosterpack only uses I2C pins, so just chose a booster pack that doesn't use those pins with other functions besides I2C 

Hi Mario,

     At this TI booster pack link below, filter the search for "Tiva C Series", and you will see booster packs that are compatible with Tiva Launchpad and should be stackable. 

     http://www.ti.com/ww/en/launchpad/boosterpacks.html

     There are several display booster pack that are compatible with Tiva launchpad.

     Just additional info, all booster packs that are compatible with Tiva Launchpad are designed to current booster pack standards. Most booster packs that are compatible to MSP430 Launchpad are not designed to current booster pack standards. But, there are some booster packs that can be used for both MSP430 Launchpad and Tiva Launchpad.

Thank you Markel, the real expert as spoken :p i was not aware of that search tool from TI.

Thank you Markel and Luis Alfonso,

Actually, that is the link I read, and as you can see there are the Sharp Memory LCD BoosterPack and the SensorHub Booster Pack, but the do not seem to be stackable!

 Hi Mario, try choose from these two LCD boosterpack:

http://forum.43oh.com/topic/4169-22-320x240-color-lcd-booster-pack/#entry37618

 This is the RobG 2.2" display using ILI SPI based on MSP single row than full tiva, you can stack it up on TIVA too, take care about selection strap and definitively remove zero ohm resistor from board, solder a 100Ohm resistor instead, it can run without burning the processor...

This is Dany Rebollo I don't see there for a while, using an oldest CPLD from xilinx extended expandability of his boosterpack. To use this one customization maybe some change need on HDL code too.

 About family I started a comparison never was continued due to biggest noise on this forum and some worst attack:

http://e2e.ti.com/support/microcontrollers/tiva_arm/f/908/t/345187.aspx

 Remember remove the R9 R10 zero ohm resistor before to damage your board if you plan use all the pin exposed to booster connector.

Thank you Roberto,

But, still, I dont see how it can work with the senshub boosterpack with the TIVA TM4C123GXL. When I take a look here: http://www.ti.com/lit/ug/spmu290/spmu290.pdf , in Table 2 (section 2.1.1) you can see the connections. When I look there http://forum.43oh.com/topic/4169-22-320x240-color-lcd-booster-pack/  I do not see a possible pin correspondence.

Regards,

Both, booster packs don't have male headers. So, you can't stack them. If you can put a male header at one of the booster pack, maybe you can stack them. But, you have to make sure of the pin compatibility of the two booster pack and the Tiva Launchpad

 Both pack don't have pass trough connector so you need plug one and wire the other to the first with some arrangement of pass thru. As alternative can I suggest you migrate to TM1294XL? for a few more bunch you can have two boosterpack socket and both sensor hub and LCD can stay together, processor is more powerful and maybe code can also be combined with less pain.

Yes, actually I thought about that, but the TM1294XL is out of stock right now. I'll try with a Nokia 5100 LCD screen. Another choice could be to try with a mobile phone with usb OTG, I guess something can be done. Thank you.

As one w/long experience designing/developing and selling displays - suggest that you NOT do that!  Most phone displays are not, "user friendly" - spec's may prove hard to find/incomplete - & "intermittent" operation due to the uber fine-pitch, flex-cable exit too often is, "normal/customary."

Suggest that a more standard character or small graphic display - or a small, SPI-based OLED be (instead) considered.  Often it's best to design for, "easy repeat use" - not, "because component is available/present!"  (yet otherwise flawed)
