MLX90614 (I2c.frequency(I2C_STD) failed #701

Closed Segredo12 closed 3 years ago

Segredo12 commented 3 years ago

Hello everyone one.

I'm trying to use the MLX90614 with this library and I'm having some problems to property work with it. I'm using Raspberry Pi 3 Model B+ with the next code: PS: I'm using Java.

System.out.println("MLX90614 Example"); MLX90614 sensor = null; for(int i=0; i<=10; i++) { try { sensor = new MLX90614(i, javaupm_mlx90614.DEVICE_ADDR); System.out.println("Sensor succesfully created !"); break; } catch (Exception e) { System.out.println("Failed to create sensor -> " + e.getMessage()); } } if (sensor != null) { System.out.println("Sensor created. -> " + sensor.name()); System.out.println("Ambient Temperature: " + sensor.readAmbientTempC()); System.out.println("Object Temperature: " + sensor.readObjectTempC()); } I'm having the next exception: "UPM Invalid Argument: MLX90614: I2c.frequency(I2C_STD) failed".

Can someone tell me what I'm doing wrong or it is problem with the hardware ?

I discovered that mraa while creating the address was cousing an error with the hardware, so I found another solution using Java and Python at the same time. Executing python scripts and reading its values onto java.
