This past year we proved out most of the hardware and learned a lot in the process. Currently I have the design for a new PCB and frame for the quadcopter nearly complete. More recently I've been working on the software side of things. The firmware is based off the AeroQuad project, and will run on top of Energia. Right now my focus is on getting Energia released for the C2000 LaunchPad. I'm happy to say we will be doing a public beta in December of Energia for C2000.https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/256948/instaspin-quadcopter/1056019Thu, 14 Nov 2013 17:24:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:cc5835c4-cbf5-4417-b390-b7022dbbfd72Arne ReykowskiAny update on this project? Thanks, Arnehttps://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/277443/drv-8834-stackable/1029312Tue, 08 Oct 2013 22:47:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:fdb381a9-b425-47a3-8d20-133896e1b038Michael PrairieMax, Thanks as well for the project. I assigned the exact thing (Booster Pack with the DRV8834) to students last week as a PCB layout project for learning how to use Eagle, and then I stumbled on your version a couple days ago. I am having them use through-hole components from bench stock for all but the DRV8834, so we'll have some differences. We had trouble finding the library component for the DRV8834, so I hope to snag it from your schematic. Any suggestions or updates would be appreciated. I left the design goals open so a one-motor stepper controller is the minimum, but I challenged then to come up with something they could stack to control three motors. We'll see what they come up with. Thanks again...

The iOS app was created by a third-party contractor and is proprietary. We are working to release the app onto iTunes.” Best regards, B. Mirshabcc2541https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/257217/ads1293-wireless-ecg-stellaris-launchpad-booster-board/1027474Sat, 05 Oct 2013 15:16:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4916f5a8-ebb0-471d-939a-f685cbae0aeeoleg petrovskyHi Bahram. I've seen many comments on the forum regarding the availability (or in this case unavailability) of the application source code running on CC2541 on top of the BLE Stack interfacing to ADS1293 like in this demonstration: http://focus.ti.com/general/docs/video/Portal.tsp?lang=en&entryid=0_ijl2ira7 is there a reason this iOS application and the CC2541 application code was not made public? Is it because of the ECG GATT profile is not finalized? Would it be still OK to peek in to the interface implementation to ADS1293 based on CC2541 SoC? Many thanks!cc2541ECG With Bluetooth Low-EnergyADS1293https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/257217/ads1293-wireless-ecg-stellaris-launchpad-booster-board/984253Sat, 03 Aug 2013 09:11:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:70711903-3c9b-4902-97e6-783273f5dc17Bo Nystedt102116Hi Mirshab When we saw your presentation of CC2541 together with Stellaris LM4F120 on "7534.ADS1293-LaunchPad-Booster-Board-4-8-13.pptx, we were quite happy and hoped we could get the source code for the LM4F120 as well as CC2541. We are very interested in LM4F120's interface to ADS1293, because in our project (now in late prototype stage with SAM4 and nRF51822) we need to make heavy use of the ARM Single Cycle MAC Insructions for our hand-coded assembly windows,and filter algos (to insulate the P-waves in ECG). We saw immediate a possibility to great improvements using the LM4F120/CC2541 presentation. Getting hold of the source code for all its implications is essential for our product strategy, as you certainly understand. So if there is a chance to get the desired source code, we are prepared to change direction and hold the fiber laser for a while. Kindest regards Bohttps://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/257217/ads1293-wireless-ecg-stellaris-launchpad-booster-board/983272Fri, 02 Aug 2013 05:46:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:c5600501-2220-4083-a34f-7b766dc05bc1Bahram MirshabHi Bo, Please see the link below for downloadable app. note and sample code.

Nice to hear that it was useful for you. Sure I'm interested in your design. In the meantime I improved the design too, added a potentiometer to set the driving current. I'm going to use 0 Ohm resistors to make it stackable and will post the updated plans soon.https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/277443/drv-8834-stackableFri, 12 Jul 2013 05:35:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4801b445-a6d8-480c-84c5-11235d051d7cBen SorensenOther Parts Discussed in Thread: DRV8834 I like your design. I learnt a lot from it. I have an idea to make it stackable that you can take a lot further. It's on EAGLE. Please send me your email address if you're interested.

We have moved up to 11.1V 3S batteries, and have new 2900 and 3800 KV motors which should spin a little faster. We will be testing with the smaller two blade props, but if we can't get enough lift from them I also have some new 5030 3 blade props which should give us a little more umph (but will require lengthening the PCB). Also of note, the motors are a beautiful shade of red and black which mirrors the TI colors. I'll post another update once we get these guys spinning and quantify the thrust we get.https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/256948/instaspin-quadcopter/942822Thu, 06 Jun 2013 01:26:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:c4678125-ca0f-44f4-8402-0d3ef799c45eTrey German289Nico, We are using some special unreleased software to control the motors, but it will be coming out very soon. For now you can use the standard sensorless BLDC control algorithms already in controlSUITE. As we move forward with the design more information will be released as it is ready. I just don't want anyone to make mistakes that I've already made.

Congratz! :) Can you please post the control code (using the 28027) for spinning the motors. I am trying to build a 30A ESC using a 28027(C2000 launchpad) + drv8301 + 6 x N-channel mosfets :) My motors for my Quadcopter are KV1120 (they need more then 13A max, else the drv8332 would have worked nicely) Regards Nicohttps://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/256944/bluetooth-audio-amplifier-boosterpack/942380Wed, 05 Jun 2013 18:52:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:8cb55dd4-a0e0-4adf-9ab1-7673e9aaa642Trey German289Baluba, I actually had that heatsink lying around and just cut it up with a table saw to get the size I wanted. I looked for an appropriate heatsink that I could get in quantity, but it proved difficult to find a good one.https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/256944/bluetooth-audio-amplifier-boosterpack/941809Wed, 05 Jun 2013 03:46:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:c01cf8c7-f483-4be7-9601-b20fce53951cBaluba RozetHi Trey, You had a nice ideea to use a Bluetooth audio link with your amplifier :) I am building an amplifier using TAS5611. Can you please suggest a heatsink to be used, like the one you have on the board presented on Youtube ?

Here's a quick status update video: http://youtu.be/Kkeyz3raP-Mhttps://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/256948/instaspin-quadcopter/938514Fri, 31 May 2013 02:16:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:1c11d1f9-677e-4012-891f-a9888981731cThanh H TranHi Trey Thanks for the response. I've always interested at controlling the motors directly and have a board that has everything in one PCB. My code was hosted here: https://code.google.com/p/simple-flight-controller/source/browse/ The discussion about the project & list of videos are here on the first page: http://www.rcgroups.com/forums/showthread.php?t=1335765 At first the copter was a as big as 20" in diameter. Then it's shrunk down to palm size (3.6" motor to motor)https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/256948/instaspin-quadcopter/938501Fri, 31 May 2013 02:04:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:e578b15a-f88f-40fd-913e-6ded780c82e2Trey German289Thanh is correct about the motors. I heard about your copter at the DIY event and I'm definitely interested in leveraging some of the work you have done. We are currently having some trouble getting the motors spinning on the actual quadcopter board, but this should be resolved soon. Then I will focus on the software. Can you post some links to design information and/or videos? I'm curious how you implemented the software for the 430.https://e2e.ti.com/administrators1/microcontrollerprojects/f/ti-employee-boosterpack-design-challenge/256948/instaspin-quadcopter/938467Fri, 31 May 2013 01:29:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:9d8f5f03-c886-42ea-b331-2a92569eabd0Thanh H TranThose motors look like HobbyKing 5g brushless motors. Trey, I made a small palm size quadcopter running with TI MSP430F2274 and CC2500. (I called it "simple flight controller").
