[GitHub] benmccrea opened a new pull request #1431: Reduce I2C timeout values to reduce system latency when failures take place

benmccrea opened a new pull request #1431: Reduce I2C timeout values to reduce system latency when failures take place
URL: https://github.com/apache/mynewt-core/pull/1431
 
 
   Most I2C devices will respond in well under 1ms but currently the timeout in most drivers is specified as OS_TICKS_PER_SEC/10. This causes undue latency in recovering from I2C errors. This change adds syscfg to some drivers to specify a smaller I2C timeout of 3 OS ticks. 
   
   Also changes BQ27Z561_LOG default value to 1, since the original default value of 0 can cause I2C errors on the device to go unnoticed.
