Error check is just my String to be printed when no ack package is received. Before starting a file transfer or any other commend, there should be ensured, that the check-packet is properly answered by the ack-packet (See fxReverse 4.10.1). Could you log the bytes, which are actually exchanged by t...

I updated the Code now with checking for Ack, but its still not working. As soon as i connect the calculator to the Arduino, change cable to 3pin and press "RECV" my console is printing: _|0000000|_Error check _|0000000|_Error check _|00000000|_Error check _|00|_Error check _|000000|_Erro...

What is the calculator's response to the 0x45 command? Usually you have to wait for a response-Packet (F. i. ACK) after sending a command or a data packet. ... Serial.write("56");//checksum(calculated from everything after command) ...wait for ACK sendData("12345678"); ...wait fo...

I think one really shouldn't rely on a zero terminator when working with serial numbers, as they might contain zeroes, which would cause weird behaviour anyway. Just to ensure that people, who use the serial number in their programs, are not concerned: The serial number of the casio fx-9860 calcula...

A memcpy isn't necessary, the following suffices: //8-byte unique ID const unsigned char * deviceId = (unsigned char *) 0xA000FFD0; Then you can use deviceId the same way as you'd use workbuffer , except for writing of course. The problem with the serial number is, that it is not terminated by a ze...

Perhaps you could try to trigger the bootcode OS update by simultaneously holding down F2, 4 and Ac/ON and pressing the RESTART-button about one second (the calc should show a blank display after releasing the keys) and finally pressing 9 and x consecutively (hold down 9 and x about a second each). ...

Long time since. I do not remember. I have the notion, that I had noticed some according code while browsing OSes.

Once you access the storage memory out of the emulator, a file CasioUserROM.mem in the project directory INIT is created. Unfortunately parts of the contents seem to be packed or encrypted. It looks as if the contents cannot be easily read or written.

Considering the error "** L2011 (E) Invalid parameter specified in option "input" : ""C:\Program Files..." you should check first, if you installed the SDK in a directory "C:\Program Files..." which name contains the string "(x86)". The SDK does not ...

Did you hit EXIT?
