c18 bit test
How bit manipulation is done by using C18 compiler from Microchip
I mean if i want forexample to test a certain bit in a character whether it is clear or set how to do this in C18
is there any equivalent in C for assembly instructions like BTFSS,BTFSC
etc
manchester coding sample
Yes its really very simple to manchester encode and decode the data manually by ourself or by using a lookup table in a mcu
But what i want is some function to encode/decode the data in a mcu
manchester coding
Can some body give me C code to Manchester encode and decode a byte of data .
I am using PIC18F452 mcu and C18 compiler.
I need a function like
Encode(byte in)
{
return (byte [2] manchester);
}
Decode(byte [2] manchester)
{
return(byte out);
}
pic18f y rf
the data corrption is not due to interference from any other transmitter this is confirm.
I cant use any other RF module as i have already purchased these.
please give me some links to good resources for manchester encoding and its implementation in mcu
It was also suggested to...
sampling frequency in pic18f252
I am using RF modules operating at 418 MHz with modulation scheme as CPCA(carrier present carrier absent).RF transmitter have serial data input while RF receiver has serial data output.
I interfaced the RF modules to the USART of PIC18F452 mcu.Sent data from...
Re: RF tranceiver problem
Both RF modules have power down pins when a logic 0 is given to that power down pin that module goes into very low power mode and cant transmit or receive and by controlling the supply i meant that i am controlling the power down pins
yes i am using only serial data...
RF tranceiver problem
Iam using RF transmitter TXM-418-LR and RF receiver RXM-418-LR from LINX TECHNOLOGIES both modules are connected with the mcu PIC18F452
Modules have seperate antennas.I am using them as half duplex tranceiver
transmitters datain pin is connected to TX of USART and recivers...
hmm i guess i was wrong that i cant handle that byte of data received from the sensor
any way
though it might sound like that i am aklsing for spooon feeding but literally i can not understand that how i am going to convert a my ascii code back to decimal or hex form, the stuff which i receive...
well tahts ok
but my problem is taht i am taking input from my sensor, this input is stored in mcu and then its sent to pc, where i receive it in ascii, during all this time i dont have any chance of editing it, can any one now guide me to solve the isssue
calculating baud rate in mcc18 compiler
ok
i will try out these new settings
but i would like to know
that how u concluded taht instead of 0x0B should be replaced 0x0C
ne way me out to check whether these new settings work or not,
Added after 1 hours 39 minutes:
and also if i want to know...
we know that when we send the data in the form of bytes from mcu to pc, the windows os will convert this bytes of data from binary to their ascii code, now if i want the data to convert back to their decimal form rather than ascii form , then what should be done for that
yes a 500mAh battery can provide 500mA current for one hour
For example if ur load draws 10mA current then your battery can provide this current for 500mAh/10mA=50 hours
