2020-06-11Wire: add sensible defaults to setWireTimeoutMartino Facchin
2020-06-11Introduce non compulsory Wire timeoutGreyson Christoforo
move timout handling into its own function change timeout from milliseconds to microseconds don't forget operating slave address or the bitrate when we reset because of a timeout Co-Authored-By: Witold Markowski <witold.a.markowski@gmail.com> fix delay datatype uint16_t --> uint32_t Update libraries/Wire/src/utility/twi.c fix mix up using TWBR instea of TWAR! Co-Authored-By: Matthijs Kooijman <matthijs@stdin.nl> Update libraries/Wire/src/utility/twi.c fix 2nd TWBR/TWAR mixup Co-Authored-By: Matthijs Kooijman <matthijs@stdin.nl> twi_stop() should use the same timeout as everywhere else all while loops are now protected by timeouts Revert "twi_stop() should use the same timeout as everywhere else" This reverts commit 68fe5f1dae1bb41183bb37eeda3fb453394a580c. make timeout counter volatile rename timeout function for improved clarity - resetting the twi interface on timeouts is now optional - timeouts in the ISR are no longer hardcoded and now obey the set timeout value - a user-readable flag is now set whenever a timeout occurs - the user can clear this flag whenever they like
2017-11-13UnConfigured I2C Slave ISR Causing Rebootchuck todd
In a MultiMaster I2C environment, The Default value of 0xFE in the TWAR cause the Arduino to respond as an I2C Slave device at address 0x7f. If the Wire.h library was not configured as a I2C Slave, `Wire.begin(slaveID);` the Callbacks for `twi_onSlaveTransmit()` and `twi_onSlaveReceive()` are never initialized. But, they are called during servicing the TWI ISR. This causes a reboot of the Arduino by jumping to an uninitialized function address (0). So, this fix initializes them to the Default Wire.h handler which will respond correctly even during Master Mode operations. A MASTER MODE only Arduino will respond to all Slave Calls that match TWAR, Unless the TWEA bit is disabled outside of Master Transactions. Chuck. It also initialized the TWAR to the General Call ID (0x0) and Disables General Call responses. Chuck.
