Re: [Tinyos-help] Question about I2C
Jose,You can communicate through I2C with external devices using Tinyos 1.x. Take a look at tos/platforms/MSP430/MSP430I2CPacket and tos/platforms/telosb/I2CPacketC I2CPacketM. Make sure you take care to arbitrate the bus, since the radio chip is on the same USART.Regards,Matt[EMAIL PROTECTED] wrote: -To: tinyos-help@Millennium.Berkeley.EDUFrom: [EMAIL PROTECTED]Sent by: [EMAIL PROTECTED]Date: 06/01/2006 02:31PMSubject: [Tinyos-help] Question about I2CI need to know if someone it's been working with the I2C protocol in the TMOTE iv, specifically with Tiny OS 1.1.X distribution, not in Boomerang.I need to connect the node in slave mode to another hardware.

Re: [Tinyos-help] Question about I2C
Even though I've reviewed those archives, but I have the following doubt. In the MSP430I2CC.nc file contained the primitives for setting the operation modes. Start is generated by the I2CPacket component, whenever read or write is made. In the StdControl.start a call to USARTControl.setModeI2C is made where is configurate for to work like a master. My question is in which moment it is suitable to make the call for to configurate in slave and to assign the OwnAddress??. After knowing clearly this, when recognizing tmote its direction would generate a ACK immediately, and would begin the reception? If this is correct, these had to be processed byte to byte and which events are generated when information is received??. Thank you very much. -- José Ulloa Suárez El Jueves, 1 de Junio de 2006 14:38, Matthew J Whelan escribió: FONT face=Default Sans Serif,Verdana,Arial,Helvetica,sans-serif size=2DIVFONT size=2PJose,/PPYou can communicate through I2C with external devices using Tinyos 1.x.nbsp; Take a look at tos/platforms/MSP430/MSP430I2CPacketnbsp; and tos/platforms/telosb/I2CPacketC amp; I2CPacketM.nbsp; Make sure you take care to arbitrate the bus, since the radio chip is on the same USART./PPFONT size=2Regards,/FONT/PPFONT size=2Matt/PP/FONT/FONTBRnbsp;/P/DIVFONT color=#990099[EMAIL PROTECTED] wrote: -BRBR/FONTblockquote style=PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #00 2px solid; MARGIN-RIGHT: 0pxTo: tinyos-help@Millennium.Berkeley.EDUBRFrom: [EMAIL PROTECTED]BRSent by: [EMAIL PROTECTED]BRDate: 06/01/2006 02:31PMBRSubject: [Tinyos-help] Question about I2CBRBRFONT face=Default Monospace,Courier New,Courier,monospace size=2 I need to know if someone it's been working with the I2C protocol in the TMOTE iv, specifically with Tiny OS 1.1.X distribution, not in Boomerang.BRI need to connect the node in slave mode to another hardware.

Re: [Tinyos-help] Question about I2C
Jose,Sorry, It didn't register the first time I read your question that you are wanting to use the Tmote as a slave device. If I were you, Iwould forget about using any of the components or interfaces available, except for reference. I would recommend taking a look at chapter 15 of the MSP430 F16xx Family User Guide (found at ti.com) which deals with I2C setup. Using that as a reference, you should be able to access registers directly to configure and read from the USART0 as I2C.Matt[EMAIL PROTECTED] wrote: -To: Matthew J Whelan [EMAIL PROTECTED]From: [EMAIL PROTECTED]Sent by: [EMAIL PROTECTED]Date: 06/01/2006 03:40PMcc: tinyos-help@Millennium.Berkeley.EDUSubject: Re: [Tinyos-help] Question about I2CEven though I've reviewed those archives, but I have the following doubt.
