Earle F. Philhower, III c4623f4297 Disable Wire slave interrupt on ::end (#621) 
Fixes #620

Earle F. Philhower, III 10b869ef30 Fix XIAO RP2040, allow swapping HW units 0/1 (#606) 
Add plumbing to allow `Wire`, `Serial1`, `SPI1` to map to the 2nd
hardware unit for devices where the PCB layout only brings out the
2nd port.

Fix the Seeedstudio XAIO pins

Fixes #594

Earle F. Philhower, III 24583494c6 Fix Wire::available() when ::requestFrom fails (#604) 
Avoids returning 2^32 bytes in the case of a requestFrom read fails
due to timeout.

Earle F. Philhower, III a3a5abac23 Fix Wire I2C restart handling (#586) 
Fixes #585

On an I2C bus restart, call the onReceive callback and clear the buffer.

Thanks to @DWiskow for the debug and patch!

Earle F. Philhower, III c4046602f0 Allow changing I2C clock speed while running (#459) 
Fixes #458

Earle F. Philhower, III 25b9ca821e Only call Wire.onReceive if data is available (#423) 
The Pico HW seems to generate an interrupt on the end of every I2C
write cycle, even if the slave address wasn't actually targeted.
This would cause the onReceive method to be called with a 0-len
parameter for every write on the I2C bus.

Now, only call onReceive if there is 1 or more bytes of data available.

SirSydom 3585c58688 Reset the SDA and SCL pins to INPUT at Wire.end() to prevent multiple pins connected to I2C when changing pins (#302) 2021-09-03 08:40:18 -07:00
Earle F. Philhower, III 580970cd72 Use Stream::setTimeout to specify I2C TO (#263) 
Use the existing Arduino Stream method of setTimeout to set the Wire
I2C timeout delay.

Fixes #260
