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

Hi,
If you use TinyOS-1.x, you can achieve it with assigning
different channel numbers to each sensor. Oscilloscope application shows
the mote id and channel to eparate each sensor readings.
If you use T2, i wonder the answer and i want to know it.
Because in osilloscope application, there is no channel number.

Subject: [Tinyos-help] Oscilloscope single mote multiple channel
display
Hello,
I'd like to know whether it is possible for Oscilloscope java
application to display multiple sensor readings from a single mote? For
instance, I have a sensor board which has accelerometer-x,
accelerometer-y and temperature sensors. The sensor board is mounted
onto a single mote. Can the Oscilloscope application display multiple
sensor channels from the setup?
I've tried displaying multiple channels before but it requires
multiple motes, each mote corresponding to one channel but it's not
efficient and quite wasteful to have many motes if I can use just one
mote to display multiple readings.
Thank you
