TIDA-01624: CC2640

Fisher-san

Thank you very much for your reply.

So I have to watch the DIO ,but not Pin.

TIDA is using DIO_1(pin9) as SCL, DIO_2(pin10) as SDA, DIO_5(pin22) as wakeup.

Lauchpad CC2640 is using DIO_1(pin6) as Free, DIO_2(pin7) as RXD (looks no connection)

DIO_5 (pin10) as SDA.

I am studying with i2c source (TMP117).

So do I need to connect SCL to pin6 and SDA to pin7 then?

Do I need ex pull up for iic?

This is YS.

I am sorry about above.

Please forget last sentence.

Thank you for your reply.

I have tried as above, but it is still not working.

And I tried to install TMP116 sample, but it can not be even inport to the CCS.

What am I wrong???

Hello

I found very big problem.

I dont think the program is lorded propery.

I am using CCS V10.11

I put TIDA sample to

C:\ti\simplelink_cc2640r2_sdk_2_20_00_49\examples\rtos\CC2640R2_LAUNCHXL\blestack\tida_01624

I think I could build them. Then I pressed debug, it stopped

  line200 of main.c

terminate debug anyway,then reconnect the board to power,

I can see BLEmed in my phone, but it looks not working.

Anything wrong with lording?

Hi Shibata-San,

The code included with TIDA-01624 was not written for the CC2640 Launch Pad. Can you clarify what your hardware setup looks like? Do you have a schematic?

If you can see the BLE med patch in the Simple Link SDK Explorer App you should be able to connect to it by selecting the icon.

thanks for your reply.

According to

I Thought it is able to connect TMP117 and LaunchPad .

I have both schematic of TIDA-01624 and Launchpad.

I didnt notice difference of CC2640R2FRSMR(TIDA) and CC2640R2FRGZ(Launchpad)

Do they need different code?

Hello Mr. Makoto Kitamura,

Thank you for contacting Texas Instruments Customer Support. I apologize for the delay on our response as we have experience an influx of inquiry in conjunction with the holidays.

In reference to your inquiry, I understand that you are looking for alternative to the TIDA-01624.

Yes, you are correct. You can use the LAUNCHXL-CC2640R2 and TMP117EVM to recreate the functionality of the TIDA-01624. You just have to follow the connection on the schematic of TIDA-01624 and you are good to go. For the firmware, the LAUNCHXL-CC2640R2 has an on-board debugger. Thus, you will not be needing the TMDSEMU110-U. Kindly refer to the links below for some important files that you might be needing as your reference for this project.

Hi YS,

I was trying to get clarity on your hardware setup, it appears I had misread your initial post, my apologies. This should be possible as long as all the connections are correct. What hardware are you using for the TMP117?

This is the start of the main.c file, when running the debugger it will always start here until you indicate that it should continue.

Can you clarify what you mean by not working? It sounds like you are seeing the advertisements but not able to connect, is that correct?

The code is likely loaded properly if you are seeing the auto-advertisement, but may be hanging if it cannot communicate with the TMP117.

As an initial step you should connect an oscilloscope or logic analyzer to your I2C lines to see if the communication to the TMP117 is working properly.  Since you are using the code as is, please also ensure that you simulate the wake-up pulse during your troubleshooting (i.e. pull down DIO_5 while the program is running).
