Hello,
Yeah it works now! Thank you for the clear instructions!
I've managed to get many sensors to display on oscilloscope from single mote
although there seems to be many data loss as seen from the graphs jerky
movement and rough plots. I think that is because of data packet collisions
from the different sensors when they are transmitting.
Thank you so much for the help!

Hi,
In the beginning, i have to warn you that you should understand what you
did.
Assume you have X and Y sensors.
1. modify this part in OsciloscopeM.nc;
uint8_t packetReadingNumber;
uint16_t readingNumber;
TOS_Msg msg[2];
uint8_t currentMsg;
to,
uint8_t XpacketReadingNumber;
uint16_t XreadingNumber;
TOS_Msg Xmsg[2];
uint8_t XcurrentMsg;
uint8_t YpacketReadingNumber;
uint16_t YreadingNumber;
TOS_Msg Ymsg[2];
uint8_t YcurrentMsg;
And you have to modify whole code in OscilloscopeM.nc to differentiate the
X and Y sensor readings and their reading numbers.
2. In OscilloscopeM.nc file, double the task named dataTask as XdataTask
and YdataTask. For XdataTask, assign channel 1 and for YdataTask assign
channel 2. (Of course you can change the numbers.)
task void XdataTask() {
struct OscopeMsg *pack;
atomic {
pack = (struct OscopeMsg *)msg[currentMsg].data;
packetReadingNumber = 0;
pack->lastSampleNumber = readingNumber;
}
*pack->channel = 1;*
pack->sourceMoteID = TOS_LOCAL_ADDRESS;
3. When you read X sensor and Y sensor, call XdataTask and YdataTask
respectively.
4. You have to double the ADC interfaces in OscilloscopeM.nc (If you
sample X and Y sensor readings from ADC)
interface ADC as ADC1;
interface ADC as ADC2;
5. Combine them ADC1 and ADC2 interfaces to appropriate ADC channels in
Oscilloscope.nc
It needs more dealing and if you don't understand the modification, it
gets confusing. I am looking forward to hearing good news.
Enjoy the day,

display
Hi, thanks for the help!
I'm currently using TinyOS-1.x though,
I'm still learning nesC and need more detailed explanations on how to
assign different channel numbers to each sensor. Where exactly do I
alter/add these channel numbers ?
Thanks
