really...where do i get on that list? Maybe the PicCommunity, LLC should d= o a collabortive effort :-) Dave King wrote: Mmmmm project sounds suspiciously like = the RFP for the army let out a few months back. Dave -----Original Message----- From: Assad Ahmed = Alright so i have been suggested to use piclist for help and here i am. Project Description: Using several non-invasive sensors to obtain readings = of the vital health parameters such as ECG, Body Temperature, Respiration = and Blood Pressure and also GPS to determine user's location; and transfer = data recieved wirelessly through Bluetooth. The sensors output either a digital data or analog -- preferably digital, i= f = not A/D convertor. My part of the project: I have nothing to do with the sensors, that is for another person in my = group to figure out. My part of the project is to take the sensor outputs, = use these ( sensor outputs) as inputs to a micrcontroller which does A/D = conversion if required, and transmits the data recieved in Real-Time throug= h = a Bluetooth Module to a Bluetooth Enabled Device. This is all proposed to b= e = done in real-time with the option of storing the data only when its recieve= d = by the bluetooth enabled device. Now, there are two ways of doing this, according to my research and thinkin= g = at this point. Having the sensors' outputs connected to 1 microcontroller which controls 1 = bluetooth module and transfers the data through it. This would however = include wires through the sensors individually which would limit the = portability of our design. Also i have not figured out how to transmit data = in real-time through the sensors, if there is more than one sensor = transmitting simultaneously. Though i believe the time to transmit data of = sensor would be very small, so it should not be something too complicated. Moving on to the second design. Sensors having thier individual bluetooth modules and transmitting data = individually through each. So the person can wear them and monitor data in = real-time whenever desired or take out one or another instead of having to = wear all of them individually. Hence quite portable. So that is the general overview of what i am trying to do and with a = reasonable knowledge of using micrcontrollers, i think i can narrow it down = to either one of the designs. Now the problem and why i am posting for help here. I have no experience what so ever with microcontrollers , either programmin= g = in Assembly Language or C. But, i am very much interested in learning and = this is mainly why i chose this part of the project so that i can actually = learn and apply at the sametime. I have however done my research, and looked into PIC18F and dsPICs. I = believe my project will not invovle any DSP since we will keep filtering et= c = within the sensors' design. I believe i can use either PIC18 or PIC16. Which one would be easier given = that i have experience with C programming.. i don't know since i have not = worked with microcontrollers before. I would be comfortable in learning any = one of PIC16 or PIC18 providing i have reasonable resources that would guid= e = me step by step. I have been looking into the forums at microchip's website, and have not = found it that helpful. Everyone suggested i look at the datasheets and to b= e = honest, i didn't understand much. I have looked in the bluetooth module and i think i am willing to go with = WBTV42-D-SPP by Wintec Industries. It provides USART and SPI interfaces and = i would be using whichever i can learn easily to use. Questions: 1. If anybody thinks there is a better bluetooth module that i can go with, = i would highly appreciate that. 2. Which PIC should i go with ( Supports USART or SPI ? ) 3. Where should i start ? A good book? 4. Any other suggestions of what i should be thinking or looking into at = this point?
