#read_Memory_WithoutMultiplexing(path:, addressStart:, addressStop:, bits8_or_bits16_DataSize:, latency:) ⇒ Object

Read parallele memory in asynchronous mode (blocking function) but callBack data is used to receive packet

  • addressStart

    32 bits address

  • addressStop

    32 bits address

  • bits8_or_bits16_DataSize

    0 for 8 bits operation & 1 for 16 bits operation

  • latency

    latency in ns range 7ns to 1600ns=1,6ms

Return USB_STATE End with TIMEOUT_RECEIVE but need to check if received the right number of bytes to ensure all is correct
