Hello
I am trying to make USB connection to PIC18f14k50.
Following are connections :-
Pin 1 (Vdd)------>5V
Pin 2 & 3 -------->External crystal oscillator (20MHz)
Pin 4 (MCLR)------------->Pulled high with 10K
Pin 20 -------------------->GND
Pin 17---------------------> capacitor (0.1UF)...
Hi dear all,
I have been working on my school project for couple of weeks and I'm trying to make RFID Door Lock by using Pic16f877A and RDM6300 RFID reader , I made a code works on PROTUS but I interfaced the cards tags as decimal number like(123456) and after that I noticed that all RF cards...
Hey all ,
I hope you are doing well and staying safe during this pandemic,
I have posted before that I'm working on a Door Lock system project with RFID module and key pad using Pic16f877a and I want to add QR to my project .
after a saw the answers I did not know actually what to do for that I...
Hello,
I'm working on a project using a PIC24F as a USB Joystick. The code was originally based on the Microchip MLA HID Joystick example. But the project requires being able to send the Joystick commands to change it's mode. As well as receive data back.
Based on research it seemed like...
Hi, guys. I am working on my final year project. I've been trying to interface the Matrix Keypad & 16*2 LCD along the with PIC. However, I wasn't able to get it to work. The LCD is able to display the 'Enter Duration' text but does not display the content of the 'Duration' array. The...
Hi everyone,
Im trying to get an htrc110 to read an ID to my pic 32.
Ive already got all the pcb development done and now all I have to do is write the code.
Ive read the datasheet at least 4 times now and it doesn't supply any sort of examples to help out and the software library doesn't...
Hello
Is that I had a doubt as a student, I want to do the programming of 10 stepper motors 12v to 2.5 A, but it turns out that I do not know which module to use since I will use a pic to program the sequence, due that requires a lot of voltage is necessary to mount an external source or there...
Hello Engineers, I am currently trying to control rotation of a stepper motor by coding with C/C++. What exactly do I need to have apart from an IDE, microcontroller and stepper motor, or is that it? Is there a specific PIC?
Thank you.
Hi guys, I've been studying CAN protocol for a while and I can't understand Filter and Mask in CAN description . I'm referring PIC24H series for studying ECAN.
my Question is
1. why do we need Mask register?
2. won't the filter register be enough to accept incoming CAN messages?
3.How does...
Hello everyone
My name is Mauricio, I'm new in this forum.
I am student of the first semester , so I do not know that much about electronics, I got really interested in this kind of topics and I am trying to make some little projects for the microcontrollers PIC using assembler coding.
I have...
So, I decided to start an 8x8 LED matrix project using a MAX7219 and PIC18F4550. My issue I've run into is that my the LED matrix I found is a max 2.7 forward voltage drop. The MAX7219 outputs around V+ -1.The minimum amount for V+ is 4V so this will put me near the 2.7V maximum of the matrix...
It appears config bits are not being set or followed on my PIC. Is there some thing disabling this feature?
I have been struggling with programming this PIC, even though I have much experience with dsPIC30s. First, I haven't been able to get it to switch clock speeds from the FRC /4 which is...
I am coding on pIC16F886 IC. I am trying to generate Fire alarm siren with PWMsignal . I have few questions as below. I copied code from **broken link removed** My spaker circuit look like this video , I am sending PWM pulses instead of audio Input mosfet circuit
I could able to produce based...
Hello lovely people
I'm just getting my head around CORDIC multiplication and division. It sort of makes sense in a fuzzy kind of way.
What I actually want to do is 2 extra levels of complication:
1) 32 bit maths on an 8 bit pic, so I need 4 bytes for everything
2) the actual calculation is word...
Hello All,
I am using two 74HC595 Shift Resisters for a 4digit SSD.
The problem is that the display needs to be delayed while scanning through the digits. I do not want to use delay since while the display is on, nothing can work as the processor is busy in delay loop. So I thought I will use...
Hello Guys,
I am trying to implement a delay using timer0 interrupt. I'll just post an abstraction of the code in mikroc
void inittimer()
{
//Timer initialization for a 32ms interrupt
}
void interrupt()
{
//interrupt code;
delayvariable++;
}
void main()
{
TRISB = 0...
Hey everyone.
It's know it's been done 1000's of times before, BUT, I'm interested to know if the way I'm doing it is a good way.
So basically I'm driving a 4x16 LCD (44780 controlled) in 4-bit mode.
I set aside 64 bytes of ram (in bank 1) to use as LCD Character place holders.
Throughout the...
Hello I want to generate a PWM for my application. I am using PIC16F1939, MicroC and PICkit 2 to burn the program.
Here's my code-
void interrupt()
{
if (TMR2IF_bit == 1)
{
CCPR1L = 100;
TMR2IF_bit = 0;
}
}
void main()
{
C1ON_bit = 0;
C2ON_bit = 0; //...
Hi folks,
I am trying to send a data frame over uart of pic12F1572.
I want to send an frame from PC terminal [I use Hterm] in the format "RGBFF00F0\n" and receive it at PIC.
I have done code but somehow I found it's not working
anyone have the idea?
a code ,hint or solution is highly appreciated...
Hi, I was wondering whether somebody could help I am a student and am using the Yenka CAD software to program a PICAXE chip, I was wondering whether anybody knew how to perform arithmetic in a flowchart on a variable x such as division e.g. x / 58. Is this possible with this chip /software, or...
I'd like to make a little programmable timer to countdown minutes and seconds. Doesn't even have to be particularly accurate. I have a 16C57 (bought long ago) I can use and a 16F57 to test on, which I know are ancient but still plenty adequate for this. It needs to (indirectly) drive a...
Hello everyone, I'm new to this forum so if I post in the wrong place or I make any mistakes, pls tell me!
As the title suggests, I'm new to PIC microcontrollers
So I just bought a PIC 12F629 but the I realised that I don't have any programmer for PICs :banghead: so do any of you guys know any...
Hi!
I started this topic because I want to discuss a problem related to PIC controllers (12f629 and 16f628A). I will try to give you all the details of this.
The problem is: after succesfully compiling the code and burning it in the PIC's memory, when I put the controller in the circuit...
Hi, i'm working with pic32 and I2C, specifically DS2482 I2C to OneWire chip. I'm reading some DS18B20 Onewire temperature sensors, everything works fine, except under certain contitions (randomly), sometimes it seems onewire bus stops responding.
Now I'm checking the code to see if everything is...
