Part Number: CC2640R2F
Other Parts Discussed in Thread: SYSCONFIG, , LAUNCHXL-CC2640R2
Hi,
For cc2640R pin assignment, I no see about UART/SPI pin
I have question about pin assignment for communication via UART/SPI
I want to connect cc2640R with MSP430 via UART or SPI
Which pin is nessary for bluetooth communication such as TX, RX , interrupt , reset and etc ?
How many wire for connecting ?
Thank you
Best regards,
Hi YK Chen and TI support team,
Note with thanks
I am starting development between BLE CC2640R2F with external MCU
I have question about pin diagram for CC2640R2F design as figure below
Note: Green color: use for connecting, Red color: No connected and Yellow color: not sure for connecting
1. If I connected pin as green color, Is it enough for BLE using ?
2. Has CC2640R2F shutdown pin ?
3. Is the yellow color pin nessary for connecting ? Can I no connect ?
4. How should I do the pin is not connected (ex. DIO, X32K and etc)? Leave open, connected to GND or etc ?
5. For JTAG_TMSC and JTAG-TCKC, Can flash program from external MCU ? How can I connect to external MCU for flashing program ?
Thank you
Best regards,
Hi YK Chen and TI support team,
From LAUNCHXL-CC2640R2 Design Files in LAUNCHXL-CC2640R2_1_0_0_Schematics page 2
1. What is the external flash use for ?
2. Is it nessary to use ?
Thank you
Best regards,
