ADS1293 wireless ECG Stellaris LaunchPad booster board

Hi

Very interesting board project. Will be perfect to add to my ECG electrode. Are there some source code to download? Have searched but not found.

Best regards

Bo

Hi Bo,

The CC2541 BLE stack can be downloaded from http://www.ti.com/tool/ble-stack

We are in the process of posting the ADS1293 C code in the Git public folder, it should be available within the next few days.

Please the installation of the ADS1299 is true for the acquisition of EEG signals? and how to convert the binary string (27 bytes "3 byte start and 8 channels of input") on real numbers ADC24bit (SEGMA delta)?
thank you

Please Help me anyone please please 

Hi Bahram

Very interesting project, especially when you use LMF120XL Launchpad. I'll use EK-TM4C123GXL which is almost the same as LMF120XL Launchpad because I need the multiply and accumulate instruction while doing FFT and FIR filtering. Suppose you have some experience of that too? Please tell me how you implemented the transformation and filtering. Mutual interestsI hope.

Hi again

Sorry, I forgot to mention  my special interest in your "Digital Signal Enhancement Algorithm" you mention in the slide show. Will you please tell me more about it. I suppose it could be useful when doing FFT and FIR filtering in my battery driven wireless project. By the way, I see no use of LDOs in the schematic named ADS1293 SchDoc dated 3/15/2013. Didn't you use any in your ASS1293 LauchPad Booster Board?

Hi Bahram

In April this year you wrote " We are in the process of posting the ADS1293 C code in the Git public folder, it should be available within the next few days."

I can't find the C source code. What happened? Have I missed something?

Kind regards

Hi Bo,

Please see the link below for downloadable app. note and sample code. The app. note shows how to interface to ADS1293 with  sample C code.

Hi 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
Bo

Hi 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!

Hi,

“For the CC2541 source code, please contact hanyu@ti.com. The iOS app was created by a third-party contractor and is proprietary. We are working to release the app onto iTunes.”
