Call for Design - SD-Card + EEPROM + SRAM + 40-pin connector TFT BoosterPack for LaunchPad


Recommended Posts

@@Rei Vilo - can you point me towards the libraries for the LCDs?  I'm on the download page and couldn't find any links referencing HX8352-A or either of the SSD drivers.  I was hoping to pull some implementation information from the libraries.  It'll help me figure out the connections.

 

Thanks!

I'm reading this, and I'm thinking that the MSP430 and Stellaris are sufficiently different that it is not the best strategy, in my opinion, to try to make one design fits all.  Doing external memory and SD on a stellaris is rather simple, because many Stellaris parts support SD and external memory without any additional glue logic.  Just make sure your bus traces are roughly the same length and ground-backed.

 

If you still want to make something universal, what would be the most bold would be to include a small CPLD for doing bus routing based on SPI configuration.  :)

3- Wait for the next LaunchPads featuring 80-pin BoosterPack! :smile:
 
Final Wrap-Up: I'd consider the SPI 16 GPIO expander option.

 

 

I know it is blasphemy to bring up ST products on a TI-focused forum, but sometimes the job is easy and cheap when you look at another manufacturer.  The STM32F4 Discovery is low-cost, it is very similar to the Stellaris, and it has a ton of I/O.  I think it is a more-suitable platform than the Stellaris LP is, for doing display-enabled projects.  For doing robotics projects, generally I think Stellaris is better, so of course nothing is the best for everything.

Thanks for the comments and suggestions.

 

Actually, there are many other parameters to take into account: IDE available on Mac OS platform, use of Wiring framework, ...

 

The compatibility across platform answers the way I develop: I start with a comfortable Stellaris and downsize the code afterwards to fit into a MSP430G2553 or the new MSP430F5529.

OK, so it is really a display frame buffer pack for the MSP launchpad.  That makes more sense.  One interesting option might be to use an FRAM MSP430 as your bus serializer and "EEPROM."  Maybe it's possible to use the DMA to always push SPI to-and-from the port register, without any CPU interaction.
