- apa102 benchmark used image.CMYK, which was added in go 1.5. This has the side
effect of making benchmark BenchmarkDrawSlowpath a bit faster.
- mpu9250 used type aliasing by accident, which was added in go1.9.
- periph-web used http.Server.Shutdown(), which was added in go1.8.
This is important to enable portability across platforms.
- UART_TX, UART_RX, UART_RTS, UART_CTS
- SPI_MISO, SPI_MOSI, SPI_CLK
This could break users who were depending on the previous wording but that would
be highly surprising.
- precalculate clock idle polarity and remove clockOn()/clockOff()
- check for higher (unknown) modes and reject them
- move internal functions down, to be grouped together
- idle clock on Connect
- Handles clock-related Mode options for bitbanging SPI.
- Adds error handling for each errorable operation in spiConn.Tx
- Adds support for NoCS mode option
- Re-adds early catch for unhandled modes, now just HalfDuplex and
LSBFirst
Fixes#266
Used the following:
go get github.com/kisielk/errcheck
errcheck -ignore 'Close|rintf' ./...
While some are irrelevant, there were some genuine issues so this is worth
enforcing, hence a few innocuous places were 'fixed' so that the list could go
down to zero.
Do not enforce this in travis yet, but should be done soon.
It regressed in e9544992d9. :( This is due to
integer overflow. Tested against the executable compiled from periph v2.
Refactor the tests to make the error messages clearer.
Fixes#256
Provides some basic functionality for initialization, self-test,
calibrarion and reading the gyroscope and accelerometer data.
Uses SPI interface, I2C is yet to be implemented via the separate
transport.

The rationale is that both intensity limiting and temperature correction can
still be used with 8 bits resolution, but perceptual mapping can't.
Make the documentation clearer about the implications. Add global PassThruOpts
to make its clear for users.
Add example for ToRGB() using PassThruOpts.
Add unit tests.
Add flag -g to cmd/apa102.
Extracts a condition from the inner raster loop, increasing performance by up to
25%.
Fix bug in dst overrun.
- Convert existing tests to table-driven
- Make reading []byte diffs easier by aligning lines
- Should be a no-op in terms of what's being tested and with what data
The remainder is ALL_CAPS, underscores and golint confusion when multiple
exported variables are defined on a single line.
No functional change except one error string tweaked.
display: move devices.Display as display.Drawer
This removes the last interface from devices, which was misplaced due to
historical accident. The new package display will also be the location for an
interface for text output only devices.
Remove io.Writer from this interface. While it's a good performance optimization
for some drivers, it shouldn't be required.
Change Draw():
- Return an error, so that communication erorr can be surfaced correctly,
instead of an adhoc driver specific Err() method.
- Move go1.8+ test code using t.Run() into separate file conditionally compiled
on go1.8+. It's not a big deal to partially lose test coverage on <1.8 as long
as the main code runs fine.
- Run coverage before race checker to help get results faster.
- Fix typo.
- No need to run travis on recent versions, they are handed by gohci workers and
they are faster. :)
- Change DefaultOpts to be a struct instead of a function. This makes the godoc
much more descriptive.
- Change InputStatus() to accept a slice, so that the driver will be able to
eventually support the flavors cap1155 and cap1166.
This is borderline pedantic but enables 30*physic.MegaHertz which I think is
more readable than 30000000, reducing the risk of typos.
Do not change Stream.Resolution() gpiostream yet, but I'll likely change it too
to match in a follow up.
