![]() ![]() You should fix your I2C bus problems before using the tTimeout (). My problem is this: if one node card (microcontroller) fails or leaves the network, the Master seems to block indefinitely while doing Wire.endTransmission(). It does not exist on other boards and there is no fix for it. Hi Im using an I2C network to connect a couple of Arduclemas (an Arduino derivative with screw terminals on all pins, and I2C pullUp resistors). It was not a overall wide introduction of a timeout. This bug can be also forced if you put a screewdriver on I2C Analog Pins 4 or 5 during a moment. My problem is that periodically Arduino Freezes. I tracked this down through the libraries and it invariably leads (through different ways) to a Wire.endTransmission command in the i2cdev library (line 295), in the call to I2Cdev::readBytes(). The tTimeout () was added to the AVR branch of boards (Uno, Mega, and so on). Forum 2005-2010 (read only) Hardware Interfacing. In void setup () We Start Serial Communication at Baud Rate 9600. To locate the Wire.h library in the Arduino installation path and modify its buffer size, take the steps outlined below: Close the Arduino IDE if open. Being able to change/modify it’s buffer size is very useful for I2C/TWI device communication. ![]() First of all we need to include the Wire library and softwire library for using I2C communication functions in STM32F103C8. The Wire library is used to communicate with I2C/TWI devices. With the example code MPU6050_DMP6, the measurements are really good, but the duino periodically freezes. In Master STM32 let’s see what’s happening: 1. ![]()
