ETSIModem (const NamedList& params, const char* name = 0)
| ETSIModem |
Constructor
Parameters:
params | Decoder parameters |
name | The name of this debug enabler |
~ETSIModem ()
| ~ETSIModem |
[virtual]
Destructor
void reset ()
| reset |
[virtual]
Reset this decoder (modem and UART)
Reimplemented from UART.
bool recvByte (unsigned char data)
| recvByte |
[virtual]
Push a data byte into this decoder. Reset this UART and call decode after validated a received message
Parameters:
data | The byte to be processed |
Returns: False to stop feeding data
Reimplemented from UART.
static TokenDict s_msg[] | s_msg[] |
static TokenDict s_msgParams[] | s_msgParams[] |
int idleRecvByte (unsigned char data)
| idleRecvByte |
[protected virtual]
Process an accumulated byte in Idle state
Parameters:
data | The byte to process |
Returns: Negative to stop, positive to change state to BitStart, 0 to continue
Reimplemented from UART.
bool recvParams (MsgType msg, const NamedList& params)
| recvParams |
[protected virtual]
Process a list of received message parameters
Parameters:
msg | The message type as enumeration |
params | Message parameters |
Returns: False to stop processing data
bool decode (MsgType msg, const DataBlock& buffer)
| decode |
[protected virtual]
Process (decode) a valid received buffer. Call recvParams() after decoding the message
Parameters:
msg | The message type as enumeration |
buffer | The accumulated data bytes |
Returns: False to stop processing data
bool createMsg (NamedList& params, DataBlock& data)
| createMsg |
[protected virtual]
Create a buffer containing the byte representation of a message to be sent
Parameters:
params | The list containing message parameters. The name of the list must be a valid (known) message |
data | Destination message data buffer |
Returns: False on failure (an 'error' parameter will be set in params)
Reimplemented from UART.
