spongebob Posted March 19, 2011 Report Posted March 19, 2011 How to connect FT232BL with PIC18F452? I tried to connect directly, but nothing happened. I used Yamaha and Roland driver. the yamaha driver did not want to transfer data. I connected a RX and TX of FT232 with each other and test in hyperterminal. data is passed to and returned. Quote
TK. Posted March 20, 2011 Report Posted March 20, 2011 Maybe the FT232BL transmits at the wrong baudrate? (I've no experiences with this chip... at the time it was released I already developed my own MIDI interfaces ;)) Best Regards, Thorsten. Quote
spongebob Posted March 22, 2011 Author Report Posted March 22, 2011 My midibox is burned with ID to use with MIDIbox-to-COM Interface Can I re-burn controller with 0000000000000000 ID and connect ft232 directly to PIC without optocouplers? Quote
TK. Posted March 22, 2011 Report Posted March 22, 2011 The FT232 chip has to be connected directly to J11 (without optocoupler) anyhow, because it works at TTL level and not as a current loop like MIDI. With All-Zero ID the MIDI interface will run at a common MIDI baudrate of 31250 - is it possible to select this baudrate on a FT232? Best Regards, Thorsten. Quote
spongebob Posted March 23, 2011 Author Report Posted March 23, 2011 Yes, it is possible to select 31250 bps on FT232. Can I work at 38400 bps? (My controller will be work with Ableton, Tracktor and other software) Should I close DTR and DSR on ft232 as shown in the picture. Quote
spongebob Posted March 24, 2011 Author Report Posted March 24, 2011 Yahooooo! :) It works! 1) Reinstall MIDI-to-COM Roland driver 2) Reinstall FTDI driver 3) Connect Rx and TX lines through 220 Ohm resistors P.S. Yamaha driver don't work :( Quote
