RSP1 Radar Processor

Datasheet

8 Software Parameter Settings

Parameters may be set by the command interface. It works at 38.4kBaud, 1 stop bit and no parity.

8.1 Parameter Storage

All parameters except real-time and debug parameters are permanently stored into the processor-

internal EEPROM.

Fig. 11: EEPROM parameter organization

Parameters are divided into classes:

8.2 Parameter Format

Parameter changes (except class W and D) will be directly stored into the EEPROM user space.

Parameters are set by a serial UART interface and may be set by a host CPU or by an ASCII terminal:

Physical format:

38.4KBaud, 8 bit data, 1 stop-bit, no parity ("8n1")

Format:

Request with prefix $; answers come with @ prefix

<CR> represents Enter key (0x0D hex)
