◆ is_updating()

bool esphome::nextion::Nextion::is_updating ( )
overridevirtual

Check if the TFT update process is currently running.

This method provides a way to determine if the Nextion display is in the process of updating its TFT firmware. When a TFT update is in progress, certain operations or commands may be restricted or could interfere with the update process. By checking the state of the update process, the system can make informed decisions about performing actions that involve communication with the Nextion display.

Returns
true if the TFT update process is active, indicating that the Nextion display is currently updating its firmware. This implies that caution should be taken with commands sent to the display to avoid interrupting the update process.
false if the TFT update process is not active, indicating that the Nextion display is not currently updating its firmware and is in a normal operational state, ready to receive and process commands as usual.

◆ set_protocol_reparse_mode()

bool esphome::nextion::Nextion::set_protocol_reparse_mode ( bool  active_mode)

Sets the Nextion display's protocol reparse mode.

This function toggles the Nextion display's protocol reparse mode between active and passive. In active mode, the display actively parses incoming data. In passive mode, it does not parse data unless specifically instructed to do so. This is useful for managing how the Nextion display interprets incoming commands, especially during initialization or in scenarios where precise control over command processing is needed.

Parameters
active_modeA boolean value indicating the desired reparse mode.
  • true to set the display to active protocol reparse mode, where it actively parses incoming commands.
  • false to set the display to passive protocol reparse mode, where command parsing is done only on explicit instruction.
Returns
bool Returns true if all commands were sent successfully to the Nextion display, indicating that the mode was set as expected. Returns false if any of the commands failed to send, indicating that the desired reparse mode may not be correctly set.

◆ upload_tft()

bool esphome::nextion::Nextion::upload_tft ( uint32_t  baud_rate = 0,
bool  exit_reparse = true 
)

Uploads the TFT file to the Nextion display.

This function initiates the upload of a TFT file to the Nextion display. Users can specify a target baud rate for the transfer. If the provided baud rate is not supported by Nextion, the function defaults to using the current baud rate set for the display. If no baud rate is specified (or if 0 is passed), the current baud rate is used.

Supported baud rates are: 2400, 4800, 9600, 19200, 31250, 38400, 57600, 115200, 230400, 250000, 256000, 512000 and 921600. Selecting a baud rate supported by both the Nextion display and the host hardware is essential for ensuring a successful upload process.

Parameters
baud_rateThe desired baud rate for the TFT file transfer, specified as an unsigned 32-bit integer. If the specified baud rate is not supported, or if 0 is passed, the function will use the current baud rate. The default value is 0, which implies using the current baud rate.
exit_reparseIf true, the function exits reparse mode before uploading the TFT file. This parameter defaults to true, ensuring that the display is ready to receive and apply the new TFT file without needing to manually reset or reconfigure. Exiting reparse mode is recommended for most upload scenarios to ensure the display properly processes the uploaded file command.
Returns
bool True: Transfer completed successfuly, False: Transfer failed.
