  1. P321 Details • Directly supports 4 standards: • RS232 (+/-5V) • RS422 (5V differential) • SPI (variable voltage) • I2C (variable voltage) • Fill-group-from-file with generator syntax • Serializes data for user • Allows user to work with predefined fields • Does not preclude user directly driving • Support in on-line help

  2. Fill-Group-From-File • In options for group selection

  3. Syntax • In Manual! • RADIX <Decimal | Hex | Binary> • DATA • ASEQ <Start Val> <Incr> <Cnt> • RS232 <DataBits: 7 | 8> <Parity: Even | Odd | None> <StopBits: 1 | 2> • I2C <DevAddr> <ExtFlag: 0 | 1> <Byte Count> • SPI <Mode: 0-3> <1-8 field specifiers of the form [0:x] or [x:0]>

  4. RS232 File • What does this say? #RADIX HEX #RS232 8 EVEN 1 48 45 4C 4C 4F 20 57 4F 52 4C 44 21 21 21 0D 0A

  5. RS232 Scope trace

  6. SPI File #RADIX HEX #SPI 0 [7:0] 55 56 57 58 59 60
