    Need suggestion in designing of ZIGBEE transceiver

    Hi, No, the zigbee transceiver take cares of all that stuff.

    noise detector with alarm

    Hi wanie84, Yes, remove R13 and D1 of the second circuit and connect the collector of Q1 to VCC of the wailing alarm. And that should do it. mjohan810327

    technique through which one can generate a Sinusoidal PWM signal using a microcontrol

    Re: Sinusoidol PWM-Gating Signal for H-Bridge using a uC Hi, Yes it is possible to create a sine wave using a pic. you need to decide how many poles you want, meaning the resolution of the sine wave. create an array of points to be used. Then you need to design a low pass active filter to get...

    Do we need Manchester coding while 433 module data transmission in UART

    Hi, You get modules that can be set up for different modulation schemes. Manchester is just another medium of transmitting, but it's not necessary and normal data packets can be transmitted. If the data that you transmit needs to be secured, implement a small encryption algorithm and its done...

    [SOLVED] Reading a dip switch using one pin ?

    Hi, If the PIC has an ADC , choose appropriate resistor values and use one input to read the dip switch.

    PIC16F877A Freezing problem...!!!!

    Hi, it sounds to be that the micro in going into a state that it cannot handle because of an arithmetic action that it does not like

    Obstacle detection/distance measurement

    Hi, You can make use of infrared detection. MN

    interfacing 3.3V and 5V RS232 channels.

    Hi, You can also make use of a zener diode circuit on the Tx and Rx Pins. It will do the job. MN

    Help on PIC12 coding using Hitech C compiler and PICkit3 programmer

    Hi, Make sure that the comparator is turned off by writing CMCON = 0x07; MN

    Programming PIC 18F4550 in C

    Hi, the PIC18FXX is a higher range of micro controllers. There is slight changes to the PIC16FXX, for one the addition of the LAT register (See the data sheet for clear explanation). The peripherals is also more advanced. See Program Microchip PIC micros with C - sample source code, FAQ and more...

    Serial data or parallel data

    Hi, the data bus is 8-bits wide, thus the data is transferred to portB in one instruction cycle. Serial data is when a byte of data is transferred on one port pin. MN

    portable heart monitor interfaced with a GPS and a GSM module

    Hi, I'm not familiar with the 8051. But I'm sure it will do the job. To use C/C++ will work. Let me know if you have any questions. MN

    [SOLVED] Using Rx interrupts on PIC16f877 to receive values from PC

    Re: Interrupts on 16f877 Hi, I not sure about the correct synatx. But if it does not work I will send the correct syntax from my pc at work. You wouid do it like this: unsigned char rxbuf; unsigned char index; bit rx_flag; void interrupt isr (void) { if (RXIE & RXIF) {...

    portable heart monitor interfaced with a GPS and a GSM module

    Hi, I don't think it will be necessary for a fpga. The GPS uses a serial interface that can be configures as NUMEA output. This is basically longitude and latitude as we'll as speed. The GSM also uses a serial interface. So a micro controller will do the job. What controller are you intending on...
