I had faced the same problem, but my project was not running a motor it just operate a relay and a buzzer, and both of them were isolated from the PIC by optocoupular.
and what is the best TTL-CMOS level converter to be used with PIC16F877A?
but I have worked with ATMEGA328p-PU also its logic voltage is 5V but it works fine with GSM SIM900A , so what causes not to work with PIC?
I decided to use the diode configuration so that I can reduce the voltage by forward voltage of the diode.
from the data sheet of 1n4007 diode the forward voltage is 1.1v so for two series diode total forward voltage is 2.2V so the terminal voltage to the GSM becomes 2.8V which is within the...
here is the circuit that was initially configured.
and below is the code to send sms to the host which was written in MPLAB XC8 compiler
UART_Write_Text("AT+CMGF=1\n\r");
__delay_ms(100);
UART_Write_Text("AT+CMGS=\"+mobile number\"\n\r")...
I had designed a project that involves the serial communication between GSM and PIC. But I faced the problem of communication, Initially I used MAX232 to change the level of voltage from 5V of PIC to 3v of GSM but nothing detected from pic to GSM and vice versa, I tried to connect directly...
Here is the attachments of the past comment, I was showing the type of software I'm using,
I tried to use the programmer directly from MPLAB IDE directly I got this error
"The programmer could not be started: Could not acquire hardware tool communications resources: PICkit2PlatformTool...
I'm using MPLAB version 3.5 IDE and MikroC pro version 6.6.3
Thanks I get you about running in debug and release but how to interface the PIC so that I run in debug or release mode, because in you explanations seems that I need to run the PIC while still connected to IDE.
**broken link...
Sorry, I have got no much experience on this microcontroller, I don't know how to build for debug or release,
in case of schematic for hardware it is well soldered to all two Vss and two Vdd and the MCLR pin is connected through 10K resistor but there is no bypass capacitors. But rather than...
Thanks for your solution,
I connected the Aux pin to PGM pin of PIC16F877A and disconnected all unused pins, and try to program using LVP entry, it alerted to change configurations, I changed the LVP to ON in codes, and upload the program successful, after programming I plugged my chip to my...
I'm using PICkit2 PIC KIT2 debugger programmer + Programming Adapter M123 so during program uploading I fix my PIC on a a programming adapter, after successful uploading I fix on my board. here is my PICkit2 PIC KIT2 debugger programmer + Programming Adapter M123
It is uploading successful, and if you check for blank there is no blank, and also if you read it reads successful, but after successful programing the PIC does not work, due to the problem I decide to upload a simple code to blink an LED for every 1sec but won't work too,
There after I decided...
It is uploading successfull and if you check no blank. it also read successfull but when you operate the pic does not work.
Due to the problem I decided to upload simple code of LED blinking that blink after 1sec. but won't work.
I tried use new PIC it function successfull but when you try to...
I wrote a program to upload to my PIC16F877A. Initially it uploaded correctly using the PICkit2 programmer and the microcontroller worked fine, but when I tried to change a piece of code and reprogram the same PIC the program was successfully uploaded but when I tried to test the chip it didn't...
