sg- 70fad08a4c Update SPI API documentation for hardware driven SS. Modify all target spi_api.c implementations. spi_init ssel parameter was used incorrectly to determine master/slave mode rather than enable hardware driven SS (seems to be due to legacy copy paste). Remove duplicate copy paste code of initialization in spi_init that is done by constructor (SPI and SPISlave) 2015-04-10 00:38:27 -05:00

Sissors 86e71216fa Allow Serial pin to be NC on Freescale/NXP devices
Nordic(?)/STM should also be done, but I don't know if they do their own
stuff.

Issue is that since the mbed-assert implementation, calling pin_mode
causes an assert when a pin is NC. Since defining a serial object with
only TX or RX is a valid use case, this should be handled.

pinmap_pinout does accept NC pins, so there no guards are needed (person
who adds asserts there may also fix it in all other code).

neilt6 e57e69c772 Changed error(...) to a weak function
Made error(...) a weak function so that it can be overridden in
production projects. Also fixed several serial_api.c files that required
stdlib.h, but were getting it from error.h.

Michael Moon a249e39826 Improved baudrate calculation function.
Uses 100% integer math, delivers more accurate results with fewer iterations in less time.

Since it seems most of the NXP chips use identical math, I have also altered the other targets in this commit.

If there are non-NXP chips which use a similar serial block, consider porting to those as well

Adam Green 5d27f98c7b serial_putc() can cause rx bytes to be dropped
While fixing this issue in the various LPC* ports, I noticed a comment
pointing to this mbed forum post which summarizes this bug quite well:
  https://mbed.org/forum/bugs-suggestions/topic/4473/

This bug was introduced in the following commit:
2662e105c4

The following code was added to serial_putc() as part of this commit:
    uint32_t lsr = obj->uart->LSR;
    lsr = lsr;
    uint32_t thr = obj->uart->THR;
    thr = thr;

As the forum post indicates, this causes the serial_putc() routine to
actually eat an inbound received byte if it exists since reading THR is
really reading the RBR, the Receiver Buffer Register.  This code looks
like code that was probably added so that the developer could take a
snapshot of these registers and look at them in the debugger.  It
probably got committed in error.
