    [PIC] pic16f1829 output is just half the vdd and pk-pk is 240mv

    OK finally i found that if i make the RB5 pin an input, RC6, RC7,RB7,RB6 becomes fixed at 3.3 V constant. No effect of any toggling happens (Neither individual pin toggling nor full port toggling works). i think this indicates something. why RB5 has such dominance? plz help!!

    this is my simple code which is failing: /* * File: newmain.c * Author: Administrator * * Created on 22 November, 2017, 9:38 PM */ #include <stdio.h> #include <stdlib.h> // PIC16F1829 Configuration Bit Settings // 'C' source line config statements #include <xc.h> // #pragma config...

    [PIC] pic16f1829 output is just half the vdd and pk-pk is 240mv

    I am using pic16f1829 ssop20 package on a commercial pcb board. I also checked the continuity of all the 4 pins with multimeter, they are not shorted. When i toggle the pins one by one i found RC6 and RB7 toggle in pair i.e. RC6 does not change state when toggle alone , RB6 changes state when...

    [PIC] pic16f1829 output is just half the vdd and pk-pk is 240mv

    i have set tris bits to zero to set all the pins of pic16f1829 as output. all the pins are toggling every 2 sec as per my logic but RC6,RB7,RB5 and RB6 not changing state when toggle. what may be the reason, coz i have disabled all the other peripherals also? Plz help!!

    I noticed that when i do this all pins work fine: LATA=~LATA; LATC=~LATC; LATB=~LATB; Meaning when all pins of pic16f1829 are configured as output and all are simultaneously turned on and off then only it works fine not by doing this: LATBbits.LATB7=~LATBbits.LATB7;

    Yes multimeter also shows the same result. One thing i observed is that when i remove the spi data transfer code from my code the RB7 pin becomes a staright line at 1.84V constant and nothing happens. same is the case with RB6 sclk pin. thanks

    There is no load connected to the microcontroller pin. Only oscillator probe is connected. - - - Updated - - - There is no load connected to the microcontroller pin. Only oscillator probe is connected.

    hi all, i have been using pic16f1829 at 3.3vfor spi interfacing but the port B is not getting configured and when i configure it as a digital io it changes state as per the program but with very low peak to peak voltage equal to 240mv only as shown in the oscilloscope image. my settings are...
