|
|
|

The S32K344EVB has two RGB LEDs:
|
|
|
|
========= ===== =========================
|
|
RedLED0 PTA29 EMIOS1 CH12 / EMIOS2 CH12
|
|
GreenLED0 PTA30 EMIOS1 CH13 / EMIOS2 CH13
|
|
BlueLED0 PTA31 EMIOS1 CH14 / FXIO D0
|
|
========= ===== =========================
|
|
|
|
========= ===== ===================================
|
|
RedLED1 PTB18 EMIOS1 CH15 / EMIOS2 CH14 / FXIO D1
|
|
GreenLED1 PTB25 EMIOS1 CH21 / EMIOS2 CH21 / FXIO D6
|
|
BlueLED1 PTE12 EMIOS1 CH5 / FXIO D8
|
|
========= ===== ===================================
|
|
|
|
An output of '1' illuminates the LED.
|
|
|
|
If CONFIG_ARCH_LEDS is not defined, then the user can control the LEDs in any way. The following definitions are used to access individual RGB components (see s32k344evb.h):
|
|
|
|
- GPIO_LED0_R
|
|
- GPIO_LED0_G
|
|
- GPIO_LED0_B
|
|
|
|
- GPIO_LED1_R
|
|
- GPIO_LED1_G
|
|
- GPIO_LED1_B
|
|
|
|
The RGB components could, alternatively, be controlled through PWM using the common RGB LED driver.
|
|
|
|
If CONFIG_ARCH_LEDs is defined, then NuttX will control the LEDs on board the S32K344EVB. The following definitions describe how NuttX controls the LEDs:
|
|
|

OpenSDA Notes
|
|
=============
|
|
|
|
- USB drivers for the PEmicro CDC Serial Port are available here: http://www.pemicro.com/opensda/
|
|
- The drag'n'drog interface expects files in .srec format.
|
|
|
|
Configurations
|
|
==============
|
|
|
|
Each S32K344EVB configuration is maintained in a sub-directory and can be selected as follows::
|
|
|
|
tools/configure.sh s32k344evb:<subdir>
|
|
|
|
Where <subdir> is one of the sub-directories listed in the next paragraph.
|
|
|
|
NOTES (common for all configurations):
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To change this configuration using that tool, you should:
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt. Also see additional README.txt files in the NuttX tools repository.
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the reconfiguration process.
|
|
|
|
2. Unless otherwise stated, the serial console used is LPUART6 at 115,200 8N1.
|
|
|
|
nsh
|

|
|
Configures the NuttShell (nsh) located at apps/examples/nsh. Support for builtin applications is enabled, but in the base configuration the only application selected is the "Hello, World!" example.
