i figured out the problem , and fixed it
my next problem is i want to do serial communication with virtual terminal in proteus
Can someone help me transmit the Result into VT ?!
Onebit Add/Sub using 8051-HELP
Hello Friends:
i'm trying to do one bit simple calc(using 8051 MCU) , which can take two numbers and operator from the Keyboard (save the numbers in RAM)
then do the math
the problem i'm facing , i end up having wrong numbers when reading from RAM .
here's...
@Frag
Yes Sir this was helpful i could show up the two values
Now i have the C code for showing the values , and the main c (with the Nokia LCD)
we need to combine both to get the ability to show the real values
C0-C7 is connected from the Resistors to the port C on the pic
and then from Resistors to photo diode of the sensor
Pin 8 , 9 it's the bypass Capacitor for LCD,PIC, EPROM
i meant the picture above , anyway
here's the Design by narccizzo

you can see the electrical schematic and how to connect to the LED,photodiode
@Jongs :
@leonel : regarding the sensor , you can use two LED (infra & RED ) with the photodiode directly without the need of 555 (if you are using narracoz design )
(look on the photo provided by JONGS how he attach them directly to desired points)
other solution , which i'm doing , is to use...
Thanks Fellos
i think the best way is to change the display
i'm trying to do that , using 16x2 LCD display and modifying the code to make it working
the problem i'm facing when using a simple code to view two words (SPO2=,PPM=) (and some constant values ) in proteus it doesnt really show the...
@Fragrance : thanks for answering my question
I'm trying to do the same circuit JONGS did , i found the same problem in the display pin configuration
@Jongs , have you test the signals in the Testing points ?! if they were right as the ones given in the schematic i think you are only having...
