Subject: Test Application for SPI
To: [email protected]
Hi, I want to make an application to test if the SPI is working properly,
the idea is sending some random bytes and watching them on the oscilloscope.
I want to do this because Im trying to run the BlinkToRadio App in my
platform that has msp430f5438. When i run it nothing happens and the code
gets stuck waiting for the event AMSend.sendDone();
Is there any simple test app to test the spi already?
I tried doing:
SPIP.nc:
module SPIP @safe()
{
uses {
interface Boot;
interface SpiByte;
interface Leds;
}
}
implementation
{
void uwait(uint16_t u) {
uint16_t t0 = TA0R;
while((TA0R - t0) <= u);
}
event void Boot.booted() {
uint8_t data = 0x22;
while (1) {
call Leds.led0Toggle();
call Leds.led1Off();
call Leds.led2On();
call SpiByte.write (data);
uwait(1024*10);
}
}
}
SPIAppC.nc:
configuration SPIAppC {
} implementation {
components SPIP;
components MainC;
SPIP.Boot -> MainC;
components LedsC;
SPIP.Leds -> LedsC.Leds;
components new Msp430UsciSpiB0C() as SpiC;
SPIP.SpiByte -> SpiC;
}
This dind't work because the USCI registers are not being configured and
still didn't find how to do it.
Thanks in advance for any help.
João
