Examples for TI-RTOS

MSP430 MSP-EXP430FR6989LP Settings and Resources
Jumper settings:
•
Set
RXD <<
and
TXD >>
to provide UART communications via the onboard USB debugger.
If you use a BoosterPack with this board (
)
,
the BoosterPack fits over J1 through J4.
SPI Loopback example pin connections:
The SPI loopback example is not supported on the MSP_EXP430FR6989LP.
Resources Used:
The following list shows which MSP_EXP430FR6989LP resources are used by TI-RTOS applications on
that platform. TI-RTOS examples control which peripherals (and which ports) are used.
•
TI-RTOS Kernel (SYS/BIOS).
Uses the first general-purpose timer available and that timer's
associated interrupts. Generally, this will be Timer0_A0. The TI-RTOS Kernel manages the interrupt
controller statically without an interrupt dispatcher.
•
TI-RTOS.
— SD Card.
Uses FatFs and the SDSPI driver on EUSCI_B0 without interrupts to read and write to
files.
— I
2
C.
The I
2
C driver is configured on EUSCI_B0 to support various BoosterPacks.
— GPIOs.
The GPIO driver is used on 2 onboard LEDs: LED1 (P1.0) and LED2 (P9.7) as output
pins and 2 switches S1 P1.1 and S2 P1.2 as inputs.
— Serial.
The UART driver uses EUSCI_A1, which is attached to the onboard EZ-FET MSP430
USB chip to facilitate serial communications.
— SPI.
The SPI driver is configured to use EUSCI_B0 for SPI communications. This instance
requires 2 DMA channels for the SPI transfer, one for transfer and one for receive.
— Watchdog.
The Watchdog driver example uses Watchdog Timer A.
— WiFi.
The WiFi examples for use with the CC3100 use GPIO pins P1.5, P3.2, and P2.1 as well
as the GPIO interrupt for port 2. In addition, it uses the EUSCI_B0 pins for SPI communications.
