# ESP32 ESP-IDF and ESP8266 RTOS SDK component for vector (dynamic array)
|
||
|
||
## Tested on
|
||
|
||
1. ESP8266 RTOS_SDK v3.4
|
||
2. ESP32 ESP-IDF v5.2
|
||
|
||
## Features
|
||
|
||
1. Support for any data types.
|
||
2. The maximum size of the veсtor is 65536 elements.
|
||
3. Support external SPI RAM for ESP32 with external, SPI-connected RAM only.
|
||
|
||
## Attention
|
||
|
||
1. Do not enable SPI RAM support unless you are sure that SPI RAM is present in your ESP32 module and it is properly configured via menuconfig.
|
||
2. If SPI RAM is present via menuconfig select Component Config -> ESP PSRAM -> Support for external, SPI-connected RAM and select SPI RAM config -> SPI RAM access method -> Make RAM allocatable using heap_caps_malloc(…, MALLOC_CAP_SPIRAM).
|
||
|
||
## Using
|
||
|
||
In an existing project, run the following command to install the component:
|
||
|
||
```text
|
||
cd ../your_project/components
|
||
git clone https://github.com/aZholtikov/zh_vector.git
|
||
```
|
||
|
||
In the application, add the component:
|
||
|
||
```c
|
||
#include "zh_vector.h"
|
||
```
|
||
|
||
## Example
|
||
|
||
Create, add, read, modify and delete items:
|
||
|
||
```c
|
||
#include "zh_vector.h"
|
||
|
||
zh_vector_t vector = {0};
|
||
|
||
char example[10] = {0};
|
||
|
||
void app_main(void)
|
||
{
|
||
esp_log_level_set("zh_vector", ESP_LOG_NONE);
|
||
zh_vector_init(&vector, sizeof(example), false);
|
||
printf("Initial vector size is: %d\n", zh_vector_get_size(&vector));
|
||
strcpy(example, "Item 1");
|
||
zh_vector_push_back(&vector, &example);
|
||
strcpy(example, "Item 2");
|
||
zh_vector_push_back(&vector, &example);
|
||
strcpy(example, "Item 3");
|
||
zh_vector_push_back(&vector, &example);
|
||
strcpy(example, "Item 4");
|
||
zh_vector_push_back(&vector, &example);
|
||
strcpy(example, "Item 5");
|
||
zh_vector_push_back(&vector, &example);
|
||
printf("Add 5 items. New vector size is: %d\n", zh_vector_get_size(&vector));
|
||
for (uint16_t i = 0; i < zh_vector_get_size(&vector); ++i)
|
||
{
|
||
printf("Item position %d is: %s\n", i, (char *)zh_vector_get_item(&vector, i));
|
||
}
|
||
strcpy(example, "Item 6");
|
||
zh_vector_change_item(&vector, 3, &example);
|
||
printf("Change item on 3 position.\n");
|
||
for (uint16_t i = 0; i < zh_vector_get_size(&vector); ++i)
|
||
{
|
||
printf("Item position %d is: %s\n", i, (char *)zh_vector_get_item(&vector, i));
|
||
}
|
||
zh_vector_delete_item(&vector, 2);
|
||
printf("Delete item on 2 position. New vector size is: %d\n", zh_vector_get_size(&vector));
|
||
for (uint16_t i = 0; i < zh_vector_get_size(&vector); ++i)
|
||
{
|
||
printf("Item position %d is: %s\n", i, (char *)zh_vector_get_item(&vector, i));
|
||
}
|
||
zh_vector_free(&vector);
|
||
}
|
||
```
