As revealed in your second post, the problem is about precisely determining the tag's location rather than "detecting" it. That's far from an usual RFID application. I guess, only a multiple receiver UHF or microwave RFID system could accomplish it. You may want to start with considering available antenna positions and calculating required p

Are you sure it is displaying "Hello Wor". I think it may be "Hello Wo" and "r" will not be displayed. It happens because the 16x1 lcd will behave as 8x2. That means the 9th character will have different memory location Nandhu

Data logger is a device which automatically collects data and send it to a remote location or store it on its own memory for analyzing purpose in future.
extracta is an exe that lives in allegro install directory. I think you can simply copy extracta to working directory. You can run the extracta from command and manually extract database. Or fix your paths to point to extracta location in mentor.
Most likely the origin of library part is way off. What you should is edit library part and check where the reference is. Likely this is the issue. After changing reference to pin1 or center of component you will probably have to adjust part location in pcb.
You need to generate a new device file from librarian. You will have to make sure device file is in correct location. check your paths.
Read the compiler documentation. There is usually a directive to do this. For example, using Freescale Code Warrior, to locate a variable at a specific location and initialize it, you could write, unsigned char variable_1 @0x00000555 = 0xaa; unsigned char variable_2 @0x00000aaa = 0x55;
Sara are you sure that RSSI is implemented in your device? If not, it will be very hard to find... From what I have understood talking to some customers, RSSI is commonly used with the algorithm you mentioned (i suppose) in WIFI systems for asset location with an accuracy that hardly goes below 2 m. Any more info about the device you are

Hi! I have desinged a patch array antenna with sidelobe level less than -16 dB and return loss is better than 13 dB over the designed bandwidth (center freq. 13.7 GHz). Now the antenna need to be positioned inside a housing where the location of the antenna is fixed, i.e., nothing can be changed like distance from the radome (or cover). Distance
hi, anyone have example of ldmos PA ? i have question about how to determine the location of bias on the in\out matching lines and design of RF choke for DC. Why the design in the datasheet use two symetrical decouple path?
Some factories make such modules.You could get location information via RS232 interface with it.Their outer circuits is quite easy also. I give you two websites of them here.You can take a look. But if you want to send its information to your computer,it should be added RF modules.
Hi, Non of your code actually shows what chip you are using, but assume it is a 16F type. When you use ' PIN_I equ 0Eh ' it actually places PIN_I at memory location 0x0E which is normally a system register area. Most 16F user registers start much higher. If you allocate it as a normal user register, then loading in the value 0x04, the ide

The "CREG" command returns the location Area Code and the Cell ID. You need a command that returns the"ARFCN" (Absolute Radio Frequency Channel Number). There is no standard command for this so it varies from manufacturer-to-manufacturer. For SIMCom modules you can use the "AT+CENG" command. For Telit modules use the "AT#MONI" command. Other

At location A, I listen from (...)
there is no AT commands for cell info display or tower location Of course there is. - you get connected cell information with extended +CREG messages - manufacturers have self defined commands for monitoring connected and neighbour cells. Siemens has e.g. ^MONI and ^MONP. For the translation of cell numbers to locations, you h
To demonstrate the Watchdog in the 89S51 all what you have to do is to include the following sequence: MOV 0A6h,#1Eh MOV 0A6h,#0E1h where 0A6h is the location of the WDTRST .. and repeat it somewhere in your code so the processor is fed with it more often than, say, 15ms (Q=11,0592MHz), otherwise the “dog” will reset the uP e
I would possibly split the memory into two sections, one for your current code and the new code. You would have to create a bootloader to write to these locations. You would have to allocate a dedicated byte address for the bootloader to determine which location to write the new code. On a GPRS command when downloading new code, the micro should p
