    [PIC] CLOCK Settings in PIC18F4331

    tried the test during debugger it is working i am able to stop and start the process but i program the same with internal RC oscillator / external 16Mhz Crystal also not working i guess i must start looking at the internal osc mode first and then switch to external oscillaotor i changed the...

    [PIC] CLOCK Settings in PIC18F4331

    1641181398 i tried the above but still it is not working i think i will check the hardware now to see if the Crystal is working properly .. i tried internal oscillator also still not working after programming

    [PIC] CLOCK Settings in PIC18F4331

    Dear All i am currently doing project in PIC18F4331 it is just to read 3 Inputs in RE0 to RE2 and to send corresponding outputs to PORTB if i am running in debug mode through PIC KIT 3 i am able read and send data but if i am programming the device i am unable to read the output data. it seems...

    PIC12F675

    i have changed the code as advised #pragma config FOSC = INTRCIO // Oscillator Selection bits (INTOSC oscillator: I/O function on GP4/OSC2/CLKOUT pin, I/O function on GP5/OSC1/CLKIN) #pragma config WDTE = OFF // Watchdog Timer Enable bit (WDT disabled) #pragma config PWRTE = OFF //...

    PIC16F886 Timer 1 as counter Not counting pulses

    hi i use 5V power supply and i am testing it in the real hardware in simulation it works properly i am connecting it to PIN No 12 , RC1 It is a proper squre pulse driven from CD40106

    [SOLVED] INTERFACING MCP4162 with PIC16F886

    i think it is impossible to get a 10 Ohms output even with a parallel resistor i may switch towards to a motor + pot solution thanks for your support and help regarding my project

    [SOLVED] INTERFACING MCP4162 with PIC16F886

    hi i went through the document and i am trying it with a parallel resistance is there any other IC which can give me a 10 Ohms minimum out put

    [SOLVED] INTERFACING MCP4162 with PIC16F886

    i already tried to connect 10 ohms across when the wiper is 0x00(90 Ohms) the rest can be done in coding when the wiper is 0xFF it is still showing 10 ohms only that is the problem i am facing any idea i did the math already

    [SOLVED] INTERFACING MCP4162 with PIC16F886

    hi Mate thanks i missed that in the data sheet now it is working properly i need one more help i am trying to take a variable resistance of 10 ohms to 200 ohms using this MCP is it possible to add a parallel resistance between the two terminals
