For your record, Im using a PIC16F887.
I did try to add in other variables in my program, it's still compilable....I'll only have error when adding the bit to variable "segment"
Hi guys, im trying to design an up/down counter which consists of 8-bits data. This means I can have a total of 256 different set of bit. There's an error shown when compiling the code. Below is my code:
PORTD is my output port
unsigned int ch=0,d...
Hey guys, I'm trying to write a code of SPI, and I have 0 experience in this :
The device needs to be designed to provide translation between the RS232 and SPI protocols in
either one of the following modes:
• A1 is a RS232 receiver. It will receive a serial bit-stream from a PC and perform the...
ive drawn a double layer PCB using diptrace. Now ,the problem is ,how do I actually connect both top and bottom layer??
Here's the picture of my design:
I'm designing a PCB using Diptrace software on a single layer design, but after routing, I found that there's alot of paths which are not connected. It requires additional jumpers to connect those paths.
I've tried to place the components on different places, but it still end up the same. And...
Mate, i think u got it wrong by what i mean. i need the same input of 1 to give 2 outputs.
The schematic diagram is as follow:
where p1.0,1.1,1.2,1.3 and p3.0 are the output pins(Lets say PORTA of the MCU). While for the input, i plan to use a 5V connected to 4 inputs(Lets say...
can someone show me how to write a program which:
(i) Has 4 inputs of 5V on 4 different pins(Let's say PORTA),with switches on all of them.
(ii)The input control's 4 outputs(Let's say PORTB)
(ii)the output toggle each time a 5V is connected.(press switch once=1,press switch 2nd time=0)
ctownsend, thx 4 the help... the second diagram is just what i needed.
i need to use PIC mcu to do this. Since i'm new in programming, can u give me some guidance on how to do it? eg. how many i/o ports i need, and some examples on how to do it.
TY.
Elaborate pls.
Btw,I'm trying to pair up the HT12E on the transmission side with a microcontroller( PIC 16F887) to control the data input and address of HT12E.
