Hello
Im trying to read the default set charge current from the I2C register with Arduino.
This is my code:
// Include the Wire Library
#include <Wire.h>
uint16_t data;
void setup() {
Serial.begin(9600); // Start seriel
Wire.begin(); // Init I2C
}
void loop() {
// Reading
Wire.beginTransmission(0x6B);
Wire.write(0x2);
Wire.endTransmission();
Wire.requestFrom(0x6B,2,true);
// Read the two bytes and combine them into a 16-bit value
data = (Wire.read() | Wire.read() << 8) & 0b0000011111111100; // Mask to keep bits 2-10
// Output the result (binary and decimal)
Serial.println(data, BIN); // Print binary value
Serial.println(data); // Print decimal value
}
My output is:
Binary:
11001000000
Decimal:
1600
I think this is not right? In my opinion the register should be set to 400(decimal)?
Thanks.
Silvan
