I have already mentioned that VINH=2.4 this is Hi and VINL=0.8, while I appreciate responses to my thread but my question remains unanswered which is:
put simple if I connect a port pin of a PIC directly with the driving pin of SSM2404 whose HI/LO I have already mentioned, will it damage...
Hello All,
I am back with another stupid question, I intend to make an audio source select circuit with PIC16F876A and SSM2404. Data sheet of SSM2404 says Logic HI (VINH = 2.4 V) Logic LO VINL = 0.8 V.
My understanding is that voltage on a microcontroller port pin is 5 volts.
If I drive the...
Thanks susan,
Actually what I am trying to do is first learn 7 segment multiplexing, secondly with this program create a 6 digit 7 segment counter.
Third stage is to incorporate the multiplexing code with my RTC code of DS1307.
What/where I am doing wrong, is it syntax error or something else...
Well I did as "aProgrammer" suggested and corrected one error in char declaration the code is now compiling OK, but proteus simulation shows weird behavior. I know I am making a fundamental error in the code "CNTRL", "if statements" or "CA[]", but cant seem to put my finger on it. Appreciate if...
Dear board,
I am back with another problem with the code mentioned below:
#include<pic.h> //Define PIC Registers
__CONFIG(0x3f72);//HS oscillator, Enable(PWRTE,BOREN),
//Disable(CPD,CP,WDTEN,In-circuit Debugger)
#define CNTRL_PORT PORTA...
Thanks for the detailed explanation, and I'll keep it in mind.
But as they say "real proof of the pudding is in the eating" for now the code is working pretty well, and its not a military grade project therefore I'll just keep using it.
Hmmm, perhaps I forgot to check the thread as "SOLVED"...
Dear All,
thanks for your inputs, first of all the code was done by professional software engineer, LCD in this case works better than many other firmwares.
I dug through Hitech C manual and found that the issue is discussed at length in section 3.3.9 under "Structures and Union" and according...
Hello all,
I need slight help in understanding the following code, it is written in Hitech C, from what I understand is that LCD data (D4_D7) is defined at PORT A (RA0_RA3), but what I don't understand at which pin R/S and E are defined and if I want to change it to PORT B with different pin...
Wp100 Hi:
I wish I was good at assembly, I just beginning again after many years with C only.
I changed the code here
btfss PORTB, 5, 0
This was the original code
btfss PORTB, 2, 0
Now would any one point where to set PORTB5 as digital input instead of PORTB2
I have downloaded and compiled Microchip Bootloader for PIC18F27J53 found in Microchip Solutions v2010-08-04, the original code found in the directory has bootloader mode button located at RB2, I tried to move it to RB5 instead, I think I did change the code, however, when I compile and burn...
Re: 7 Segment Code issues - Help requested
Thanks a lot abidr.
I compiled the code but there is too much flickering and the digits are not in sequence.
Re: 7 Segment Code issues - Help requested
"abidr"
that is exactly what I intend to achieve, i.e multiplex at least 4 7 segments on PIC16F87xA, and do it in XC8 or Hitech C.
It will be kind of you to help.
