Previous to this patch the printing mechanism was a bit of a tangled
mess. This patch attempts to consolidate printing into one interface.
All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf. All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.
Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform. The former is only used when MICROPY_PY_IO is defined.
With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...). Code size is also reduced by around 200 bytes on
Thumb2 archs.
stmhal: For UART, check that baudrate is within 5% of desired value.2015-02-22T00:26:49+00:00Damien Georgedamien.p.george@gmail.com2015-02-22T00:26:49+00:00urn:sha1:77fc276c08b59d67779b726668d0b377c8ef47f0
Also includes documentation about minimum baudrate.
Addresses issue #1090.
stmhal: Add uart.sendbreak() method, to send a break condition.2015-02-13T19:04:24+00:00Damien Georgedamien.p.george@gmail.com2015-02-13T19:04:24+00:00urn:sha1:baafb290ada10c7b8ba0b4b31fb4c5ec8282be88stmhal: Collect all root pointers together in 1 place.2015-01-07T23:38:50+00:00Damien Georgedamien.p.george@gmail.com2015-01-07T23:38:50+00:00urn:sha1:3b51b3e90f1d513031ad2c6b6a2a0d5d391f753d
A GC in stmhal port now only scans true root pointers, not entire BSS.
This reduces base GC time from 1700ms to 900ms.
stmhal: Prefix includes with py/; remove need for -I../py.2015-01-01T21:06:20+00:00Damien Georgedamien.p.george@gmail.com2015-01-01T21:06:20+00:00urn:sha1:2cf6dfa280a8149941aafc852fbaae8bdfc4999estream: Convert .ioctl() to take fixed number of args.2014-11-16T22:16:14+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-11-16T22:16:14+00:00urn:sha1:f4a6a577ab133781c06aec029c806c878555730a
This is more efficient, as allows to use register calling convention.
If needed, a structure pointer can be passed as argument to pass more
data.
stmhal: Fix UART so bits counts number of data bits, not incl parity.2014-10-31T20:28:10+00:00Damien Georgedamien.p.george@gmail.com2014-10-31T20:28:10+00:00urn:sha1:4029f51842656e7a1576dbe7c41aeea3eef83645
Addresses issue #950.
stmhal: Implement support for RTS/CTS hardware flow control in UART.2014-10-31T00:40:57+00:00Damien Georgedamien.p.george@gmail.com2014-10-31T00:40:57+00:00urn:sha1:4ef67d30f17d8a9d08cc72afca9e49c0b45271d3
This is experimental support. API is subject to changes. RTS/CTS
available on UART(2) and UART(3) only. Use as:
uart = pyb.UART(2, 9600, flow=pyb.UART.RTS | pyb.UART.CTS)
