## 1. no matching function for call to 'HX711::HX711(const int&, const int&)'
|
|
|
|
I'm getting the following error:
|
|
|
|
```exit status 1 no matching function for call to 'HX711::HX711(const int&, const int&)'```
|
|
|
|
The new interface is that the begin(...) method will obtain the pin parameters. So instead of using:
|
|
```
|
|
HX711 scale(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN);
|
|
```
|
|
Use:
|
|
```
|
|
HX711 scale;
|
|
```
|
|
And then in ```void setup() { ... }``` initialize the pins like this:
|
|
```
|
|
scale.begin(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN);
|
|
```
|
|
