Adds board support for the Teensy LC board. Support is based off the Freedom KL25Z board. LED, PWM, and UART0 have been tested. The SPI pins are mapped correctly but have not yet been tested. From Michael Hope as SourceForge patch 51.

Teensy LC README
|
||||
================
|
||||
|
||||
This is the README file for NuttX on the Teensy LC. The Teensy LC
|
||||
is a DIP style breakout board for the MKL25Z64 and comes with a USB
|
||||
based bootloader.
|
||||
|
||||
Development Environment
|
||||
=======================
|
||||
|
||||
All testing was done with the GNU ARM Embedded 4.9 toolchain on
|
||||
Linux. See https://launchpad.net/gcc-arm-embedded to download.
|
||||
|
||||
Once you've configured and built NuttX, flash the resulting
|
||||
nuttx.hex file to the board using the Teensy Loader Application.
|
||||
|
||||
LEDs
|
||||
====
|
||||
|
||||
The Teensy LC has a single LED. If CONFIG_ARCH_LEDS is defined, then
|
||||
NuttX will update the LED as the board boots. The summary is:
|
||||
|
||||
* LED off: board booting
|
||||
* LED on: initial stack created
|
||||
* LED flashing: panic.
|
||||
|
||||
See `include/board.h` for details.
|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
The serial console is mapped to UART0 and appears on pins 0 (RX) and
|
||||
1 (TX). Consider using a 3.3 V USB to serial adapter such as the
|
||||
Sparkfun #9717 FTDI cable.

|

* Name: kl_spi[n]select, kl_spi[n]status, and kl_spi[n]cmddata
|
||||
*
|
||||
* Description:
|
||||
* These external functions must be provided by board-specific logic. They
|
||||
* are implementations of the select, status, and cmddata methods of the SPI
|
||||
* interface defined by struct spi_ops_s (see include/nuttx/spi/spi.h). All
|
||||
* other methods including up_spiinitialize()) are provided by common
|
||||
* Kinetis logic. To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in kl_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide kl_spi[n]select() and kl_spi[n]status() functions
|
||||
* in your board-specific logic. These functions will perform chip
|
||||
* selection and status operations using GPIOs in the way your board
|
||||
* is configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* kl_spi[n]cmddata() functions in your board-specific logic. These
|
||||
* functions will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to up_spiinitialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by up_spiinitialize() may then be used to bind
|
||||
* the SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).

|
||||
* Name: kl_spi[n]select
|
||||
*
|
||||
* Description:
|
||||
* PIO chip select pins may be programmed by the board specific logic in
|
||||
* one of two different ways. First, the pins may be programmed as SPI
|
||||
* peripherals. In that case, the pins are completely controlled by the
|
||||
* SPI driver. This method still needs to be provided, but it may be only
|
||||
* a stub.
|
||||
*
|
||||
* An alternative way to program the PIO chip select pins is as a normal
|
||||
* GPIO output. In that case, the automatic control of the CS pins is
|
||||
* bypassed and this function must provide control of the chip select.
|
||||
* NOTE: In this case, the GPIO output pin does *not* have to be the
|
||||
* same as the NPCS pin normal associated with the chip select number.
|
||||
*
|
||||
* Input Parameters:
|
||||
* devid - Identifies the (logical) device
|
||||
* selected - TRUE:Select the device, FALSE:De-select the device
|
||||
*
|
||||
* Returned Values:
|
||||
* None
