c++ serial port
Hi, i´m trying to interface serial port using DEV c++, when i used an old Dos compiler everything was easy simply use outport and inport, now for windows it´s very different, but I sussefull put data on serial out, the problem is that I can´t read data from RX pin.
It only...
qpsk schematic
Hi jontio congratulations for that project !
I´m am planinng to make some simple qam modulator using 8051 microprocessor an DAC and ADC , the modulator simple get the data via serial than if 00 it generates like a cosine wave at 5Khz for example and DAC will generate analog...
22.1184
Hi, I´m working in a project, i´m using AT89S52 with a xtal at 22.1184MHz, I need to generate a binary coded sine wave with 20KHz at P1 with max and min amplitude using the 8bits of P1, 0000 0000 for min and 1111 1111 for max . It will be applied to a hi speed DAC
For a good...
atmel 89s8253
Any one has tryied this programmer
https://rafaelbf.tripod.com/grava.htm
Will be there any problem because windows don´t give acess to parallel port?
:D
89s8253 programmer
Hi, I´m trying to program my atmel 89s8253 but i´m having problems :/
I am using ponny prog
for the base board and

qpsk demodulator 8051
Based on this project **broken link removed**
it is possible to use audio bandwidth to transmitt 16 or 64QAM modulation and get data rates up to 100kbps or more over a FM RF link.
Fully software designed it was an excelent idea!
My ideia is collect some...
data over audio
Hi, i´m planning to do a project based on QAM or QPSK for transmitting data over a RF audio link.
I have sucessful buitl a FSK FM data link, but I want to get more data transferer, so QAM or QPSK or superior digital modulation is needed.
Any ideias, schematics or any thing that...
best c compiler
Hi, what C compiler do you recommend for free?
Is keil the best? Can I programm any atmel chip?
If I see in the data shet the adress of the ports, timmers etc and declare it it´s possible to programm any microcontroller?
Tanks :)
Hi, I need some help with declaring adress in c compiler for a 89S8253:
80h P0 11111111
81h SP 00000111
82h DP0L 00000000
83h DP0H 00000000
84h DP1L 00000000
85h DP1H 00000000
86h SPDR ########
87h PCON 00XX0000
This are the default byte addressable registers in the data sheet of the 89S8253...
Hi, I need to program a AT90S8515 using a C compiler, the problem is that the C compilers that I have teste do not have the 90S8515.h include
Any recomended C compiler for this with this include.
First I was looking for the 89S8252 but it is realy expensive for projects, but i could find the...
ft232 c++
Hi, I´m working in a experiment, until now I used the serial port of the pc to send and receive the data I wanted to put there, using simple C commands, like outportb() and inportb() with bios.h, even using turbo c++ 3...
I have look to FT232 chip, but it seems a bit complicaded...
