Generator functii

Recommended Posts

Salutare !!! :smt006

am cautat pe net mai multe scheme de gerator de semnale

asta se pare a fi cea mai interesanta http://bygselvhifi.dk/freqsynth.htm

problema este ca nu merge sub 1Khz (desi MAX038 poate sub 1Khz)

 

propun pentru cei interesati sa contribuim cu idei (scheme si soft) pentru a construi un generator de semnal care sa indeplineasca urmatoarele conditii:

 

1). Frecventa generata 10Hz - 20MHz (MAX038)

2). Microcontroler PIC16F877

3). Afisare grafica LCD128x64

4). Interfata RS232 pt conectare la PC

 

astept sfaturi/idei

..sincer nu am stiut :smt102 dar am MAX038 bagat"" intr-un generator mai simplu si cu performante reduse zgomot la potentiometre ...in magazine cred ca se mai gaseste MAX038totusi daca sti un IC sa merga pana la 20MHz si sa nu fie scump ... pastram ideea !
