Cassette Interface

Addition commands

CODE FUNCTION DESCRIPTION 001100 Wait This command suspends the data transfer for a while when reading from the tape. The calculator issues it after loading of the file header, then reads a single data bit. The meaning of this value is unknown to me (the interface always returns 1). 110100 Counter This command defines the frequency of the music tone. It expects an 8-bit value (the least significant bit first). frequency = 32768Hz/value 001110 Play the sound After sending this command, signal of frequency specified by the Counter command appears on the MIC output. 111110 Stop the sound This command terminates generating the music tone. 111100 Close Apart from closing the communication channel, this command has an additional function. After sending it, the calculator can read a single data bit which returns the Cal/Music switch state (Cal=0, Music=1). Otherwise, this switch doesn't seem to influence the function of the controller.

Music playing example

1. OP=0 111100 ;test the Cal/Music switch OP=1 1 ;returned value=1, ;means the switch in the "Music" position 2. OP=0 111110 ;stop the sound 3. OP=0 110100 ;preset the counter according to the note pitch OP=1 01001010 ;value=0x52 (frequency=400Hz) 4. OP=0 001110 ;play the sound 5. delay depending on the tempo 6. goto 1, until all notes played 7. OP=0 000000 ;reset 8. OP=0 111110 ;stop the sound

Printer interface

Available commands

CODE FUNCTION DESCRIPTION 000011 Presence After sending this command, the calculator reads a single data bit. Returned value=1 means the printer is present. 011001 ??? This command always appears immediately before the Presence command, function unknown. 100001 Read status After sending this command, the calculator reads a single data bit. Returned value=0 means the printer is busy, while 1 means it's ready to accept data. 110011 Send control This command is followed by a printer control byte. Order of bits: the start bit=0 8 data bits (the least significant bit first) the parity bit 2 stop bits=1 4 "don't care" bits (the FX-602P sends 1010) The busy/ready status needs to be tested with the Read status command before any data transfer. 010011 Send data This command is followed by a data byte. Otherwise as the Send control command.

Known printer control codes

CODE FUNCTION 0x10 Prints a string using the FX-602P alpha mode. 0x11 Prints a number using the FX-602P numbers mode. 0x13 Function unknown, sent by the FX-602P to the printer after power-on. 0x1F Terminates strings sent by the FX-602P to the printer. 0x29 Selects the FX-702P printing mode.

Power-on sequence

1. OP=0 011001 ;unknown Code 011001 OP=0 000011 ;test for printer presence OP=1 0 or 1 ;returns 1 when printer present 2. OP=0 000101 ;read status - repeat this sequence, OP=1 0 or 1 ;until the interface returns 1 3. OP=0 010010 ;this command seems to be directed to the tape ;interface, perhaps it fixes some interaction ;issues 4. OP=0 011001 ;unknown Code 011001 OP=0 000011 ;test for printer presence OP=1 0 or 1 ;returns 1 when printer present 5. OP=0 110011 ;send control code 0x13 OP=1 0110010001111010 6.

Casio fx-603P Scientific programmable calculator

The FA-2 cassette interface uses the same HD43110 controller chip as the FA-3 one, so the tape interface protocol used by the FX-700P applies to the FX-602P as well.The FA-2 Cassette Interface is designed for the FX-601P, FX-602P, and FX-702P calculators. It can play musical notes as well.The FP-10 printer command codes have the last transmitted bit set.The FX-702P sends only the Reset command after power-on.The FX-702P calculator skips the 010010 commands.Numbers are printed using following sequence:1. control command 0x112. eight data bytes3. control command 0x1FStrings are printed using following sequence:1. control command 0x102. data bytes3. control command 0x1F
