|
||
|
|
|
||
|
|
## Tested on
|
||
|
|
|
||
|

1. ESP8266 RTOS_SDK v3.4
|
||
|
|
2. ESP32 ESP-IDF v5.2
|
||

|
|
||
|
|
## [Function description](http://zh-onewire.zh.com.ru)
|
||
|
|

## Using
|
||
|
|
|
||
|
|
In an existing project, run the following command to install the component:
|
||
|
|
|
||
|
|
```text
|
||
|
|
cd ../your_project/components
|
||
|
|
git clone http://git.zh.com.ru/alexey.zholtikov/zh_onewire.git
|
||
|
|
```
|
||
|
|
|
||
|
|
In the application, add the component:
|
||
|
|
|
||
|
|
```c
|
||
|
|
#include "zh_onewire.h"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
Search 1-Wire devices on bus:
|
||
|
|
|
||
|
|
```c
|
||
|
|
#include "zh_onewire.h"
|
||
|
|
|
||
|
|
void app_main(void)
|
||
|
|
{
|
||
|
|
uint8_t *rom = NULL;
|
||
|
|
zh_onewire_init(GPIO_NUM_5);
|
||
|
|
if (zh_onewire_reset() != ESP_OK)
|
||
|
|
{
|
||
|
|
printf("There are no 1-Wire devices available on the bus.\n");
|
||
|
|
}
|
||
|
|
else
|
||
|
|
{
|
||
|
|
zh_onewire_search_rom_init();
|
||
|
|
for (;;)
|
||
|
|
{
|
||
|
|
rom = zh_onewire_search_rom_next();
|
||
|
|
if (rom == NULL)
|
||
|
|
{
|
||
|
|
break;
|
||
|
|
}
|
||
|
|
printf("Found device ROM: ");
|
||
|
|
for (uint8_t i = 0; i < 8; ++i)
|
||
|
|
{
|
||
|
|
printf("%X ", *(rom++));
|
||
|
|
}
|
||
|
|
rom -= 8;
|
||
|
|
printf("\n");
|
||
|
|
}
|
||
|
