Damien George 77fc276c08 stmhal: For UART, check that baudrate is within 5% of desired value.
Also includes documentation about minimum baudrate.

Addresses issue #1090.

Damien George baafb290ad stmhal: Add uart.sendbreak() method, to send a break condition. 2015-02-13 19:04:24 +00:00
Damien George 3b51b3e90f stmhal: Collect all root pointers together in 1 place.
A GC in stmhal port now only scans true root pointers, not entire BSS.
This reduces base GC time from 1700ms to 900ms.

Damien George 2cf6dfa280 stmhal: Prefix includes with py/; remove need for -I../py. 2015-01-01 21:06:20 +00:00
Paul Sokolovsky f4a6a577ab stream: Convert .ioctl() to take fixed number of args.
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.

Damien George 4029f51842 stmhal: Fix UART so bits counts number of data bits, not incl parity.
Addresses issue #950.

Damien George 4ef67d30f1 stmhal: Implement support for RTS/CTS hardware flow control in UART.
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)

Damien George 185cb0d943 stmhal: Use OSError with POSIX error code for HAL errors.
Addresses issue #921.

Damien George 481d714bd5 stmhal: Overhaul UART class to use read/write, and improve it.
UART object now uses a stream-like interface: read, readall, readline,
readinto, readchar, write, writechar.

Timeouts are configured when the UART object is initialised, using
timeout and timeout_char keyword args.

The object includes optional read buffering, using interrupts.  You can set
the buffer size dynamically using read_buf_len keyword arg.  A size of 0
disables buffering.

Damien George 5c00757a5c stmhal: uart ioctl uses EINVAL, and checks TXE bit for write-ability. 2014-09-07 20:57:18 +01:00
Damien George e2a618615d stmhal: Fix modselect so non-hashable objects can be polled. 2014-09-07 20:41:09 +01:00
Damien George a2f55fe12b stmhal: Add polling ability to UART object. 2014-09-07 20:40:32 +01:00
Damien George ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int.
Addressing issue #50, still some way to go yet.

Damien George 951ed9d02f stmhal: Fix REPL printing by cooking output sent to stdout_obj.
Recent changes to builtin print meant that print was printing to the
mp_sys_stdout_obj, which was sending data raw to the USB CDC device.
The data should be cooked so that \n turns into \r\n.

Damien George 40f3c02682 Rename machine_(u)int_t to mp_(u)int_t.
See discussion in issue #50.

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Paul Sokolovsky 9b71b16a94 unix,stmhal: Make "mpconfig.h" be first included, as other headers depend on it. 2014-05-02 18:08:16 +03:00
Damien George 8d09640b22 stmhal: Add documentation in comments, and script to generate HTML.
Decided to write own script to pull documentation from comments in C code.
Style for writing auto generated documentation is: start line with ///
and then use standard markdown to write the comment.  Keywords
recognised by the scraper begin with backslash.  See code for examples.

Running: python gendoc.py modpyb.c accel.c adc.c dac.c extint.c i2c.c
led.c pin.c rng.c servo.c spi.c uart.c usrsw.c, will generate a HTML
structure in gendoc-out/.

gendoc.py is crude but functional.  Needed something quick, and this was
it.

Damien George 7533700393 stmhal: Rename USART to UART.
It's really a UART because there is no external clock line (and hence no
synchronous ability, at least in the implementation of this module).
USART should be reserved for a module that has "S"ynchronous capabilities.

Also, UART is shorter and easier to type :)
