Function Documentation

boolean msp430GetCommsValid

(

void

)

Gets systemMSP430CommsValid.

Returns

systemMSP430CommsValid

void msp430Init

(

void

)

Initialize MSP430.

use 400us interrupt for SPI comms. This lets us xmit our 24-byte message in 9.6 ms. At the end, we use a 32us interrupt for SPI comms. This is about as fast as the MSP430 can read bytes from the buffer. This double byte signals the end of the message for synchronizing the two processors

Returns

void

void msp430InterruptDisable

(

void

)

Disable MSP430 interrupt.

Returns

void

void msp430InterruptEnable

(

void

)

Enable MSP430 interrupt.

Returns

void

void msp430SetCommsValid

(

boolean

newCommsValid)

Sets systemMSP430CommsValid.

Parameters

newCommsValid

- new boolean value to set systemMSP430CommsValid

Returns

void

void msp430SetModeBuildMessage

(

uint8 *

data)

Set the mode for MSP430 message.

Parameters

data	-sets to MSP430_MODE_C

Returns

void

void msp430SystemCommandBuildMessage

(

uint8 *

msg)

Build a command for MSP430 message and reset command.

Used to build the command for the actual command sent to the MSP430 Reset the command to normal mode

Returns

void

uint8 msp430SystemCommandMessageGet

(

void

)

Returns

void

uint8 msp430SystemGetCommandMessage

(

void

)

Get the command.

Returns

systemMSP430 the command

void msp430SystemReprogramCommand

(

void

)

Set the next command to the MSP430 to be to enter the boot-loader.

Returns

void

void msp430SystemShutdownCommand

(

void

)

Set the command to shutdown.

Returns

void
