Mikrodenetleyici Projeleri, blog arşivinde ATTINY2313 ILE WAV PLAYER konusu "atmel* atmel avr projeleri* ATTINY2313* avr* MAX232* player* TDA2003* wav* " ile etiketlendi
Kesin bu horozu :D
Devre ATtiny2313 mikrodenetleyici üzerine kurulu MAX232 ile pc bağlantısı kurulabiliyor pc programı ile wav dosyası yükleniyor TDA2003 anfi entegresi ile çıkış güçü yükseltilmiş
The electronic circuit it ATtiny2313-mas* mikrovezérlo that of a circle is being built. AVR-hez* the memory IC (AT45DB4161) a voltage divider is attached with resistances since the memory is a maximum 3.6V-ot* is able to tolerate it. According to this Z-diódás with a stabilizer 3.3V-ra* the supply voltage is portrayed for IC. From IC it adatvzeték* the AVR re is attached directly since he is AVR the 3.3V-ot* H can perceive it as a level yet.
The digital code being equal to the sound AVR single R-2R turns it into an analogous sign with a network, mainly the cost effectiveness and I decided it because of the simplicity at this solution. The strengthening grade follows this. For strengthening IC TDA2003-mat* I singled it out mainly his plain connection, his price, and the equivalent, cca. 10W-os* because of his leave performance.
To put on a sound for the apparatus, to delete we are top notch with the help of a computer. The electronic circuit sorosporttal* is attached to the computer, this an MAX232 type next fitting accomplishes it through IC
