Other Parts Discussed in Thread: CC3100, MSP-EXP430F5529LP, MSP-EXP430FR5969, MSP430FR5969, MSP430FR6989
I have been posting and dialogging with Michael in the CC3100 forum. He suggested I also try this forum.
To Date I have not been able to successfully get the CC3100 to work with the FR6989 launch pad
- Again, my Ultimate goal: Add CC3100 WiFi to my FR6989 products
- Unbelievable that TI or some user does not have a working example.
- I am sure many people would be extremely grateful to have a posted working "WiFi email with CC3100 - FR6989
CC3100_sdk_1.3.0, CCS_8.2.0, Compiler TIv18.1.3.LTS
- Working perfectly with F5529 examples
- I successfully ported my F5529 product to the latest sdk, CCS, and compiler, Working perfectly with my F5529 products
- Working perfectly with FR5969 examples
- To Date I have not been able to successfully port it to have CC3100 work with the FR6989 launch pad
- I have used the FR6989 Out of the Box example (so very simple application to start with) and have tried to add CC3100 WiFi simplelink to it by adding files from the FR5969 example
- As outlined in the documentation in the sdk download: CC3100_sdk porting guide can be found at cc3100-sdk/docs/simplelink_api/html/index.html:
- Per the instructions I have created my own local copy of user.h (not linked to the CC3100_sdk library or since it is a linked file it will change the base file and break all other examples and projects)
- I copied all of the body from the original user.h but then had to change my copy to link to my new copies of 1) board, 2) cli_uart, 3)spi
- The pins and instance of the uarts and spi are different for each of the launch pads (see table below)
- I created boardFR6989.C and .h, cli_uartFR6989.c and .h, spiFr6989.c and .h
- In these files I changed pin numbers and Interrupt vectors to match the FR6989
- To date: I have a clean compile, it runs, I can single step and see it writing to the Back Channel uart buffer by watching the registers, but no characters are displayed on the back channel Uart and the WiFi does not work
This posting provides a link to wiki page which provides working UARTs for these launch pad.
The FR6989 UART works and the code is very well written and documented
https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/465550?help-MSP430FR6989-launchpad-deverlopment-UART
http://processors.wiki.ti.com/index.php/MSP_UART
myUART_05_example.zip …for the FR6989
myUART_5529.zip myUART_5529.zip (MSP-EXP430F5529LP LaunchPad)
myUART_5529.zip myUART_5969.zip (MSP-EXP430FR5969 LaunchPad)
My next step is going to take the working myUART_05_example.zip for the FR6989 and now try to add simplelink to it as at least the back channel UART is proven to work.
I will post my cli_uartFR6989.c code that I modified from the FR5969 CC3100 example….in case someone can spot an easy obvious error
- For the benefit other users this is the mapping of each of the CC3100 WiFi pins to the respective launch pad pin number
- I used tabs, so I hope this is still formatted OK once it is posted
