Have some 5V SPDT EM-relay (called "sugar cube" relays), rated for ~240VAC-10Amps. To switch those, I believe I cannot directly connect them to the MSP430 launchpad I/O pins, right ? I need to use a BJT/FET -- mandatorily ? The 4 relays in turn control incandesent lamps. If anyone has a circuit schematic they could share, it would be very helpful. thanks, Jay

Not sure if I am missing something obvious, but can one really connect a speaker (what wattage, internal resistance?) to P1.6 ?? Can those pins really drive a speaker ?

This is crazy awsome. I've got couple of projects where I was using IOIO, but being able to directly use USB hostmode of tablets (Android 3.x or ICS/JB devices) with MSP430 would be so wonderful. I've got few Allwinner A10 (rather A13) based tablets, but being able to retain warranty on them is crucial, so I am not able to either root the tablets, or install the drivers for usb mode emulation (voids the warranty). So, I can only wish that a libusb based user-mode solution like this one http://android.serverbox.ch/?p=549 (Android + Arduino over USB) could be made someday.

LaunchPad on steroids, if you have a lot of spare time...
jayachar88 replied to xv4y's topic in Energia - MSP
Ok, my bad! Should've followed the links. Looks like 5 USD was a limited period promotion. Anyhow, as I said, 12.99 USD with free 2-day WW shipping is hard to beat for this performance class. Look forward to ordering few for myself, but it show In-Stock and delivery in 4-6 weeks at the same time... kinda confusing. -
Software UART support in Energia, and interaction with processing
jayachar88 replied to jayachar88's topic in Energia - MSP
Have patched kernels in the past, so I think I should be able to manage it, else will come back here. Thanks for the offer.- 12 replies

Ah okay. This is much better than what I'd read earlier. Are you aware of the the CD driver patch location ?- 12 replies

And, I understand that there are no VCOM drivers required on Linux ?? Surprisingly material on Launchpad Wiki (including comments there), and some Q&A on Stackexchange indicated that the Virtual COM port of Launchpad uses a hybrid driver model, which is why serial comm with Launchpad on Linux was problemmatic. I guess that is either incorrect or history!- 12 replies

Thanks @Rickta59. Can you clarify the cost of using TimerSerial in terms of RAM, program memory ? Since this uses a timer resource, is there any other library or function that cannot be used, which also requires timer ?- 12 replies

On the 'Serial Communication' wiki entry, I see that the 'Software UART' case has not been elaborated or explained, unlike the Hardware UART feature available on v1.5 Launchpads. Can it be used to communicate with a Processing sketch running on PC (running Linux) ? Can someone please confirm that they have got the serial communication working (bidrectional) between MSP launchpad ?

Hi, As someone moving from Atmel's (both baremetal and Arduino/clones) to MSP430, I was really jubilant to find something like MSPhere, but looking at the blog and this forum, I get the impression that the project has been stopped/abandoned. Can the project owner comment ? Is there any hope of reviving the work ? For me, if TimerA, GPIO work reasonably well, without excessive bloat (beyond say 15-20% of native C code), it is good enough, although having I2C/TWI and PWM abstraction would be good. If someone has used MSPhere for such tasks, with reasonable level of success, would like to
