9.2.2.1 Read DSP Button
When the “Read DSP” button is pressed (if there is an interrupt request), the runtime application issues an
SCP read command to the DSP. The results of the DSP read are printed out in red to the “Log” window.
9.2.2.2 Reset DSP Button
When the “Reset DSP” button is pressed, it brings the nDSP_RESET line low, waits for 100 ms, and
brings the nDSP_RESET line high.
9.2.2.3 Auto Read Checkbox
When the “Auto Read” checkbox is enabled (if there is an interrupt request), the runtime application
issues a read command to the DSP. This occurs approximately every 500 ms. The results of the read are
printed out in red to the “Log” window.
9.2.2.4 Command Field
The “Command” field allows the user to issue commands. The following commands are possible:
• Hexadecimal commands sent to the DSP
• Filenames of configuration files (*.cfg)
• Comments that start with a “#” sign
Note: Users are able to issue commands to the DSP using a console window.
9.2.2.4.1 Hexadecimal Command
Hexadecimal commands allow the user to transmit an 8-digit hexadecimal number. This number must be
in the form of “XXXXXXXX”, where X is a hexadecimal digit. No hexadecimal identifier (“0x” or “h”) should
be used.
