RTOS/CC2642R: CC2642R: Porting from CC2640R2 and project zero

richard payne

Part Number: CC2642R

Tool/software: TI-RTOS

I like to port RTOS (non-postix) code which is based on project zero demo code into CC2642R to try out.

Earlier, I was forced to mask out BLE code because it interferes with UART (even I tried to disable it the BLE debug UART but it did not work, I have raised the issue in this forum earlier, one solution us to devised soft UART, which I lacked time to do this, I just mask BLE code and leave it to later works. With CC2642R, it has two hardware UART, so which UART BLE debug message code use?

I like to move RTOS code (which contains no BLE interface or BLE application code/protocol, it is standalone application code that I developed using SPI, UART, GPIO, driver, RTOS power manager etc) into CC2642R and use 2nd UART (which one?) and do some work to establish BLE interface with Android, which BLE 5.0 demo code I should start (the one with data/command exchange) from the software kit (simplelink_cc26x2_sdk_2_10_00_44 package) so I can port RTOS code in there .

Do you plan to rework project zero demo code for CC2642R and when this is released?, I cannot find it in simplelink_cc26x2_sdk_2_10_00_44 package.

Project zero I refer to this location (which is none-postix): C:\ti\simplelink_academy_cc2640r2sdk_1_14_02_04\modules\projects\ble_projectzero

Can you do hardware compare between CC2640R2 and CC2642R, the compare from the website is very shallow and does not do details comparison.

Hi Richard,

You can find Project Zero for CC26x2R included in the 2.10 CC26X2 SDK and here on TIRex: http://dev.ti.com/tirex/#/?link=Software%2FSimpleLink%20CC26X2%20SDK%2FExamples%2FDevelopment%20Tools%2FCC26x2R%20LaunchPad%2FBLE5-Stack%2Fproject_zero

On the CC26x2R1 Launchpad, only UART0 is connected to the USB UART interface on the XDS by default in the board files. However, the XDS has a second virtual COM port (Auxiliary Data Port) really meant for things like SWO trace. If you set up UART1 to output to the TDO pin (IOID16 on the launchpad) you will get that output in the XDS Aux Data port. Note that there is no input pin, so output only.

// CC26X2R1_LAUNCHXL.h
#define CC26X2R1_LAUNCHXL_UART1_TX              CC26X2R1_LAUNCHXL_DIO16_TDO

// project-zero :: main.c
    // ....
    UART_init();
    UartLog_init(UART_open(Board_UART1, NULL)); // <-- Board_UART1 here

For a detailed comparison, please compare the Features column of http://www.ti.com/product/CC2642R and http://www.ti.com/product/CC2640R2F or refer to the technical reference manuals or data-sheets.

I'm not sure I understand what you mean by "which UART BLE debug message code use", but on CC2642 the uart-log output for project zero is by default on the regular com port conncted to the XDS-USB bridge (Application/User UART).

Best regards,
Aslak
