Arduino Wire Library modified to add timeouts to the freeze-prone TWI while() loops
This is not working with
Arduino UNO R3
Arduino IDE 1.8.5
MacOS 10.13.4
Installed as described ('librairies' folder)
Replaced _#include <Wire.h>_
with _#include <WSWire.h>_
Corrected minor errors:
'Wire.write('\0');' => 'char c = '\0'; Wire.write(c);'
'Wire.endTransmission(true);' => 'Wire.endTransmission();'
Compiled (with AVR ISP)
Uploaded to Arduino
=> No I2C communication anymore
Replaced _#include <WSWire.h>_
with _#include <Wire.h>_
=> I2C communication working
The twi head in this lib is an outdated one. Are there some one going to fix it?
Sorry for my poor Eng.
There is no function to set clock frequency as Wire library. It seems fixed at 100000.
Hi. In recent versions of Raspbian something must have changed, so that I now no longer can communicate between a Raspberry Pi and an Arduino over I2C.
When using the original Wire library it works however.
