Hi everybody
This is the problem, I design an application on the Tmote Sky kit.
It have to dialog with an external sensor (I2C protocol), and send
values to an other Tmote.
I dont find some sample on implementation of the I2C protocol,
so I write it myself.
When I connect it with the sample IntToRfm, it doesnt work,
but if I connect the orther sample IntToLeds, it work very well
So I am very sad.
I someone have an idea?? thanks
This is the code of my I2C module :
module DemoI2CM {
provides {
interface StdControl;
}
uses {
interface StdControl as MSPStdControl;
interface MSP430I2C;
interface MSP430I2CPacket;
interface MSP430I2CEvents;
interface Timer;
interface IntOutput;
}
}
implementation {
bool read=FALSE;
uint8_t inc_debug=0;
event result_t Timer.fired()
{
uint8_t Data[2];
//call IntOutput.output(inc_debug);
inc_debug++;
Data[0] = 0x16; //
Data[1] = inc_debug; //
read=TRUE;
call MSP430I2CPacket.writePacket(29, 2, Data );
return SUCCESS;
}
event void MSP430I2CPacket.writePacketDone(uint16_t addr, uint8_t
length, uint8_t* data, result_t success){
uint8_t Data[6];
uint8_t DataToRead = 0x16;
if (read) {
read=FALSE;
call MSP430I2CPacket.writePacket(29, 1, &DataToRead );
} else {
call MSP430I2CPacket.readPacket(29, 1, Data );
}
}
event void MSP430I2CPacket.readPacketDone(uint16_t addr, uint8_t
length, uint8_t* data, result_t success) {
call IntOutput.output(data[0]);
}
command result_t StdControl.init() {
call MSPStdControl.init();
call MSP430I2C.enable();
call MSP430I2C.setModeMaster();
call MSP430I2C.setAddr7bit();
return SUCCESS;
}
command result_t StdControl.start() {
return rcombine(call MSPStdControl.start(),call
Timer.start(TIMER_REPEAT, 250));
return SUCCESS;
}
command result_t StdControl.stop() {
return call MSPStdControl.stop();
}
async event void MSP430I2CEvents.arbitrationLost() {}
async event void MSP430I2CEvents.noAck(){}
async event void MSP430I2CEvents.ownAddr(){}
async event void MSP430I2CEvents.readyRegAccess(){}
async event void MSP430I2CEvents.readyRxData(){}
async event void MSP430I2CEvents.readyTxData(){}
async event void MSP430I2CEvents.generalCall(){}
async event void MSP430I2CEvents.startRecv(){}
event result_t IntOutput.outputComplete(result_t success)
{
return SUCCESS;
}
