3e251a82f6 integrated Timer1 library (instead of custom code) ; but for an unknown reason it breaks the 1-wire communication (timer code doesn't work at all, or timings are wrong, or both) ; search algorithm is broken, and probably everything else as well 2017-05-03 22:06:09 +02:00

a108089f02 fixed probable cause of rare 1-wire bus deadlock where the Arduino would not release the bus and keep pulling it low forever (thanks to fari on http://www.stm32duino.com/viewtopic.php?f=9&t=1852 for posting this fix) 2017-04-25 21:11:19 +02:00

f068849a7d - breaking change: writeBit has been renamed to beginWriteBit to show it's asynchronous, and a new function writeBit has been introduced, which is synchronous and can't be called from an interrupt handler 
- fixed possible bugs when a write operation is canceled and a timer interrupt is still registered

b92a13a59d - breaking change: OneWireSlave::write has been renamed to OneWireSlave::beginWrite, to show it's asynchronous. A new function OneWireSlave::write has been introduced, which is synchronous (and can't be called from an interrupt handler) 
- added code to make sure a client completion callback will always get called, even if it's because of a reset or an error

887741a806 - added possibility to be notified of individual bits received 
- fixed bug when sending individual bits or canceling a write operation
- DS18B20 sample now sends zeros during conversion, and ones when conversion is finished

b97a643227 - breaking change: global instance of OneWireSlave renamed from "OneWire" to "OWSlave" to avoid conflict with the OneWire master library in case someone wants both libraries in the same sketch 
- upgrade to visual 2015 and arduino IDE 1.6.6

300a6be90f added background reset check (in case the master sends a reset while another operation had started) 2015-04-26 21:09:30 +02:00

2294595995 - fixed bug in Pin::attachInterrupt (this is an arduino bug : interrupts that have been triggered before the handler is attached will cause it to be called immediately ; but only interrupts happening after should call the handler) 
- changed OneWireSlave interface to make it completely static (there is an instance, but it's only a wrapper to the static stuff, so that the syntax looks nice)
- the search rom algorithm works fine most of the time, but sometimes it fails, probably because of interrupts being blocked at the wrong time (small delay to respond to the master to send a zero)

74b3f2100e search rom algorithm almost working (but code is in an awful state, and master doesn't recognize the ROM yet, maybe a CRC issue) 2015-04-24 20:17:29 +02:00
