  • @Pekka Ritamaki:

    I have tried to code PIC C (CCS) code for Nokia 3310 with PIC18F2620, but no success. I found in your place LINKS-11884.zip code for PIC16F88, but I can't get is open, it need a password Can I get your password, so that I may find my error. I have used 3.3V power, thought the PCD8544 datasheet says that it will last 7V. Here is my Nokia 3310 code ( the main part) void main () { setup_wdt (WDT_512MS ); delay_ms(100); init_tasks(); // Init PIC nokia_init(); // init nokia 3310 display nokia_clean_ddram();// clean ddram while (1) { delay_ms(100); printf( "\rShack 2023.3.21"); nokia_gotoxy(1,0); printf(nokia_printchar,"Shack 2023.3.17"); nokia_gotoxy(2,0); printf(nokia_printchar,"Ella Ritamäki"); delay_ms(100); delay_ms(1000); } } I include my schematic I have also a internet place http://remotesmart.wikidot.com ...

  • @David:

    I first saw a version of this circuit 17 years ago by a student...cheap sound for his friends. It was wonderful then and now. Notes Mount the driver on the heat sink...then there is no need to attach the diodes to the heat sink Build a jig to match the output transistor (and the input ones) Attach a fan to the heat sink Have fun ...that why we do it!!

  • @gevv:

    No wrong. There is a different connection, working system. An example of an old design (elektor); One of our readers from India made the circuit as 200w with 4 mosfets, but said that it worked perfectly when LM741 op amp was installed instead of TL071, which did not work. ...
