Ok! now i has finished project transmit successful through soundcard. My data is modulate with PSK31(BPSK,QPSK). I referenced file PSK.dll on webhttps://www.qsl.net/ae4jy/index.htm
my program is written with borland delphi7.0 base on PSK31.dll
i tested them and it run good.
I want to share with...
hs1101
this is a project mesurement and control temp, humidity for a glass house.
I used pic 16f877A with LM35 and RH humidity HS1101+ keyboard
Humidity is a RH base on Capacitor --> frequency with LM555
LM35 is input for AN0
You can enter temp min and max and delta temp. the same for RH with...
i have to a project to tranfer data between PCs using sound card. Require data is modulate FSK or PSK or HDB3 ... to packet. This is my exercise for data communication and transmission.
Please help me ? using PIC or PC, soft by delphi
Have you some idea?
picbasic count signal
In PBP you can using command COUNT for counting frequency
with 4 MHz crytal you can counting 25KHz and 20Mhz for 125KHz. if input signal you through a circuit devide frequency example div 100 or before you put it a pin on MCS PIC you can counting range into MHz.

program for at89s52
if you need a ICSP for AT89S52.It's here.File is designed in Prote*l
I re-designed a circuit for programmer AT89S/Cxx and AT89S/Cxxxx in website
sunrom.com it support for 17 difference of kinds. I will upload to 4rum. I tested it run
well. The circuit is designed in...
i designed two kits for myself to study with PIC with modules for basic to advance. You can make it better. I base on design of USBXBoard for PIC 18F4550 and PIC16F877 file is designed on ORCAD9.2
You can see and recommend for me!
have fun!
