Chapter 2. API Reference
CONFIG_ESP_IPC_TASK_STACK_SIZE
Inter-Processor Call (IPC) task stack size
Found in: Component config > IPC (Inter-Processor Call)
Configure the IPC tasks stack size. An IPC task runs on each core (in dual core mode), and allows for
cross-core function calls. See IPC documentation for more details. The default IPC stack size should be
enough for most common simple use cases. However, users can increase/decrease the stack size to their
needs.
Range:
• from 512 to 65536
Default value:
• 1536
CONFIG_ESP_IPC_USES_CALLERS_PRIORITY
IPC runs at caller’s priority
Found in: Component config > IPC (Inter-Processor Call)
If this option is not enabled then the IPC task will keep behavior same as prior to that of ESP-IDF v4.0,
hence IPC task will run at (configMAX_PRIORITIES - 1) priority.
Default value:
• Yes (enabled)
LCD and Touch Panel Contains:
• LCD Peripheral Configuration
LCD Peripheral Configuration Contains:
• CONFIG_LCD_PANEL_IO_FORMAT_BUF_SIZE
CONFIG_LCD_PANEL_IO_FORMAT_BUF_SIZE
LCD panel io format buffer size
Found in: Component config > LCD and Touch Panel > LCD Peripheral Configuration
LCD driver allocates an internal buffer to transform the data into a proper format, because of the endian
order mismatch. This option is to set the size of the buffer, in bytes.
Default value:
• 32
ESP NETIF Adapter Contains:
• CONFIG_ESP_NETIF_TCPIP_ADAPTER_COMPATIBLE_LAYER
• CONFIG_ESP_NETIF_IP_LOST_TIMER_INTERVAL
• CONFIG_ESP_NETIF_USE_TCPIP_STACK_LIB
CONFIG_ESP_NETIF_IP_LOST_TIMER_INTERVAL
IP Address lost timer interval (seconds)
Found in: Component config > ESP NETIF Adapter
The value of 0 indicates the IP lost timer is disabled, otherwise the timer is enabled.
