Prior to this commit, the actual I2C frequency can be faster than specified
one and it may exceed the I2C's specification for Fast Mode. The frequency
of SCL should be less than or equal to 400KHz in Fast Mode.
This commit fixes this issue for F4 MCUs by rounding up the division in the
frequency calculation.
Latest versions of Sphinx (at least 3.1.0) do not need the `*` escaped and
will render the `\` in the output if it is there, so remove it.
Fixes issue #6209.
By virtue of its name, the pyb module would only be available on a pyboard
and so does not need to have conditional "only" directives throughout its
documentation.
These conditionals were added mostly in
cfcf47c064 in the initial development of the
cc3200 port, which had the pyb module before it switched to the machine
module. And wipy only conditionals were removed from the pyb module
documentation in 4542643025, so there's no
need to retain any more conditionals.
New keyword option in constructor and init() method is "dma=<bool>".
DMA is now disabled by default for I2C transfers because it currently does
not handle I2C bus errors very well (eg if slave device doesn't ACK or
NACK correctly during a transfer).
Hi,
i would like to add a little clarification to the parameter "data" of i2c.mem_read(): I misunderstood
``data`` can be an integer or a buffer to read into
as "i can give a integer variable to read a integer into" . This pull-request adds the following clarification:
``data`` can be an integer (number of bytes to read) or a buffer to read into
Thanks for your great work!
Best wishes,
Matthias
