Hello ,
I am using the same Caller ID chip "NW6005" interfacing with pic16f1947. I am facing a problem like data pin of this chip also generating a pulses when you talk.I mean Speech is also a FSK Stream .so my pic is getting interrupt till i speak on a phone and if there is auto answering...
In normal mode, Osc Frq =4MHz . I switched as 31KHz (LF) in sleep.
As well as in RF Chip(TDA5252 INFINEON MADE), i had implemented full powerdown mode. Then it reduces to 1.2-1.4 mA.
When i removed RF Chip from the PCB Board ,then current is less than 100uA. So I am bit confused that due...
I tried as you suggested.I changed from 4MHz to 31KHz internal osc. in sleep. but nothing happen.
I am attaching my part of circuit and code.
Can you suggest me which module should i disable in sleep and how?
I am using PIC16LF1936 and HI-TECH C Compiler.
I want to run my code on 2xAA battery and want to calculate battery life. So I implemented SLEEP module and Watch dog timer to awake it every 8sec.
I used I2C to configure my RF chip which works as Transmitter and PIC Hardware UART module to...
hELLO ALL,
I am using PIC16F1937 , MPLAB IDE V8.7 as a software platform tool and MPLAB ICD 3 as a programmer/ debugger.
I am facing some strange problem .
When I program my board and using MPLAB ICD3 programming supply, it works good. but when I remove programming connector and apply...
Hello All,
I am working on USB HID APPLICATION using PIC18F13K50 .
My whole project is working but,
I have to send my source code to someone .They are using MPLAB ICD-3 or PICKIT-3 as a programmer. I wanted to know Which are the minimum required file to burn code on IC?
If I send...
Thanks for the quick replay..
I have attached the part of code as the original code too large....
I didn't understand the calculations they made for 195KHz output.
Please let me know , if it's required i will try to attached the whole code.
Hello All,
I am working on PIC16C54C. There is one code that I need to modify which is in assembly language.. I used to work in C code. So I don't have much idea about assembly language.
When I simulate this assembly code in MPLABSIM , it gives following error
- CORE-E0002: Stack under flow...
Hello All,
I fingered out that,
1. Tuning fork that provided on PICDEM2PLUS board , was actually not accurate.
I changed EPSON tuning fork with 20ppm and 22pf load cap.
2. I was using PC clock as reference to verify exact time. But when you start the PC it take some time to...
Hello,
In Timer1 Interrupt function When Interrupt occurs , should TMR1IF (Interrupt Flag) set to zero first or TMR1H reload first. Does it matters in clock going fast?
Below is the clock generation code. The sequence of reloading timer register and clearing Interrupt flag is shown. Please...
Thanks all for your guidance.
Yes, wp100. I agree.. There is something problematic in my code or hardware .. As I mention before that I am using PICDEM2PLUS Demo board as a development board, They have not mentioned specification about this Timer-1 Crystal. They just say it's a watch type...
Hello all,
I am currently working on PIC16F1937 . My project is Digital clock alarm with several additional features...Due to cost issue instead of using RTC Chip, I am using 32.768KHz as Timer-1 external crystal oscillator to increment time of digital clock and 4 MHz internal osc for...
Hello all,
I am trying to do PIC to PIC communication using hardware Uart. I am working on PIC16F1937 and HI-tech C compiler.
In that case i could not receive correct data.
e.g when I transmit 0b01010101 (0x55 )through one PIC , at receiver side pic receives 0x66. Following are the related...
Hello all,
I am currently working on PIC16LF1936 and PIC16F1937.
PIC16LF1936 has one UART and it is used with Transceiver chip. I need to interface it with PIC16F1937 which has again one UART and it is not used.
I think I have to implement software UART in PIC16LF1936 and hardware UART in...
