espidf.heap_caps_get_total_size() → int
espidf.heap_caps_get_free_size() → int
Return total free memory in the ESP-IDF heap.
espidf.heap_caps_get_largest_free_block() → int
Return the size of largest free memory block in the ESP-IDF heap.
Erase all data in the non-volatile storage (nvs), including data stored by with microcontroller.nvm
This is necessary when upgrading from CircuitPython 6.3.0 or earlier to CircuitPython 7.0.0, because the layout of data in nvs has changed. The old data will be lost when you perform this operation.
exception espidf.IDFError
Bases: OSError
Raised when an ESP-IDF function returns an error code.esp_err_t
Initialize self. See help(type(self)) for accurate signature.
exception espidf.MemoryError
Bases: MemoryError
Raised when an ESP-IDF memory allocation fails.
Initialize self. See help(type(self)) for accurate signature.
espidf.get_total_psram() → int
Returns the number of bytes of psram detected, or 0 if psram is not present or not configured
