3.3.1 Standard USB Read and Write Operations

Use the serial COM port to read and write registers through USB commands using the following format:

  • Read register format: rreg ADR
    • Where ADR is the address in hex, and rreg is always lower case.
    • Register addresses can be in upper or lower case, and do not need to be led by '0x'. 0 padding register addresses is also optional. For example, to read register address 0xB, some valid commands include:
      • rreg 8
      • rreg 08
      • rreg 0x08
        • When '0x' is used, the 'x' must be lower case.
    • For this example, the EVM returns the results and state (idle or collecting) in JSON format:
      • {"acknowledge":"rreg 0x08"}
      • {"register":{"address":8,"value":0}}
      • {"evm_state":"idle"}
  • Write register format: wreg ADR VAL
    • Where ADR and VAL are in hex, and wreg is always lower case.
    • Register addresses and values can be in upper or lower case, and do not need to be led by '0x'. 0 padding register addresses and values is also optional. For example, to write register address 0x1 with the value 0xfb69, some valid commands include:
      • wreg 20 f127
      • wreg 20 0xf127
      • wreg 0x20 0xF127
        • When '0x' is used, the 'x' must be lower case.
    • For this example, the EVM returns the results and state (idle or collecting) in JSON format:
      • {"acknowledge":"wreg 0x20 0xf127"}
      • {"console":"Writing 0xf127 to CONFIG1 register"}
      • {"evm_state":"idle"}
