    Radiofrequency prototype 6 天 left
    已验证

    Utilizing technology used in the automobile industry, I would like to develop a radio frequency prototype for location tracking. Automobiles use key fobs for starting a car when the key fob is anywhere within the vehicle. I would like to use this or similar technology. I am not interested in the aspect of the key fob that does remote start or opens the doors from 100 yards away. I am interested in the aspect of the physical presence of the key fob within the car and how the car recognizes the fob to be present (trunk, front seat, back seat - none matter as the car starts no matter what). Utilizing this technology, I would propose to build a prototype device using existing technology to serve as a local tracking device. For instance, with this device - we would be able to determine if...

    We need to convert C language drivers from dsPIC33EP512GP506 to dsPIC33FJ128GP306 due to the current unavailability of the former and our current old stock of PCB's with dsPIC33FJ128GP306 which we need to now use. They are very similar and essentially it is the pin usage that has to be corrected. For a guru on Microchip PIC's this will be quite easy to do. Very importantly, after I assign this project, there will be no renegotiation of the price. Don't waste my time with low ball bids and then try to ask for more money later. I'm providing the schematics and the source code plus I will answer any questions before final bid. Please do not bid if you do not have relevant experience with drivers on the PIC platform and therefore waste my time. Only make an ...

    Design a device that will work as scanner/printer machine. If the switch is on, the device will read a sentence of 10 characters from a scanner which is connected serially. The sentence is saved in external RAM memory. When the switch is off, the device will print 20 characters from internal ROM serially. The user of the device should turn the switch on or off. Initially the switch is ON. Write all your assumptions clearly. Use the 8051 for your design and use 1,200 baud rate. 3. Write a code that read characters from a device called line generator connected to the serial port of 8051 and convert the uppercase characters to lowercase. Use baud rate 19,200. 4.
