The C2000 Launchpad is Here


Recommended Posts

Good to know. I'll take a look at this. Most of the testing we do is on Windows, but we are seeing more and more customers using Linux and are trying to improve support for this platform (as well as MacOS). I've got a linux box here, so I'll do some testing before the next release.

Glad to hear people are getting their launchpads. I'm really sorry about the jumpers...in the rush to get everything done and ready I must have over looked this. If it starts to become an issue, I'm

Its almost here guys(/gals)! Boards are on their way from China to Dallas!

Secondly, I agree the download is huge and there is no reason why you need all of controlSUITE. I fully anticipated this and back in June I developed what I lovingly referred to as controlSUITE2go-LaunchPad. This was a cut down version of controlSUITE that only included what a user would need to get up and running with the LaunchPad. Marketing thought the introduction of another controlSUITE package would confuse people and they didn't like the name, so because of the time crunch as we were approaching launch we decided to drop it. What do you guys think of the controlSUITE2go branding? Does it make you think of a lightweight development package with everything you need and nothing you don't?

 

I think it makes perfect sense. Why download everything for all kits when you only want or need the stuff for one kit? Imagine the bandwidth savings! ;)

 

Third, JP4-JP11.... Confusing right?!? You can thank the boosterpack standard for this:

http://processors.wi...erPack_Standard

We had to design our LaunchPad to match the pin out of the MSP430 LaunchPad. On their GPIO mux, SPI and I2c functions are muxed on the same pins, while on C2000 devices these functions are always on different pins. This made it difficult to impossible to implement the boosterpack standard, so we had to connect multiple GPIO to each of the header pins to implement a few of those pins on the boosterpack standard. When the chip is initially powered, all the GPIOs come up Hi-Z and stay that way until configured. The thinking with these pins is that a user will configure I2c or SPI and not the other, which will allow for both of these peripherals to function on the desired pins. The JP4-11 jumpers were added so that a user can easily change how these GPIOs are routed to the pins. By defaults everything is connected per the schematic, but you can take an Xacto knife and cut through the trace that goes in between the two pads to disconnect a GPIO from one of the pins. Of course after it has been cut, one could easily (ok...they are 0402 footprints...it might take some skill) reconnect these GPIOs to a pin by soldering a 0 ohm jumper (or simply just blobbing some solder on there...less skilled approach)

 

Heh... I hate cutting traces, easier to unsolder 0402 jumpers with just about any iron, ... six of one and half a dozen the other. Guess I'l dual label them.

The jumpers we'll put in the e-store, but the lack of a crystal and associated caps is a conscious design choice. The Piccolo device has two internal 10MHz oscillators which can be used to clock the chip. Because the chip lacks any high speed asynchronous interfaces (USB, CAN, etc.), in most applications there isn't a need for the external oscillator/crystal.

 

That being said you could easily order a crystal from digkey and populate it yourself. The footprint it such that it should accept either a through hole or surface mount package.

Any possibility of getting the manufacturer to not solder the unused pads? :)

Hi,

 

Just got in my board also and ... no jumpers ... ill need to pluck them from one of my launchpads it seems ...

 

BTW the estore now states that I should order some jumpers myself ... they are cheap as chips but unfortunately the shipping is going to cost more than the lauchpad ...

 

cheers
