======
The Olimex STM32-E407 configuration is based on the configuration
olimex-stm32-h407 and stm32f4discovery.
Configurations
==============
Instantiating Configurations
----------------------------
Each Olimex-STM32-E407 configuration is maintained in a sub-directory and
can be selected as follow:
tools/configure.sh [OPTIONS] olimex-stm32-e407/<subdir>
Typical options include -l for a Linux host platform or -c for Cygwin
host platform. See 'tools/configure.sh -h' for other options. And
<subdir> is one of the sub-directories listed below.
Compile Firmware
----------------
Once you've set the proper configuration, you just need to execute the next
command:
make
If everything goes find, it should return the next two files:
nuttx.hex
nuttx.bin
You can return more kinds of files by setting on menuconfig.
Flashing the Board
-----------------
You can flash this board in different ways, but the easiest way is using
ARM-USB-TINY-H JTAG flasher device.
Connect this device to the JTAG connector and type the next command:
openocd -f interface/ftdi/olimex-arm-usb-tiny-h.cfg -f target/stm32f4x.cfg -c init -c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"
Configuration Directories
-------------------------
nsh:
---
Configures the NuttShell (nsh) located at apps/examples/nsh. This
configuration enables a console on UART2. Support for
builtin applications is enabled, but in the base configuration no
builtin applications are selected.
usbnsh:
------
Configures the NuttShell (nsh) located at apps/examples/nsh. This
configuration enables a console on USB_OTG1. Support for
builtin applications is enabled, but in the base configuration no
builtin applications are selected.
netnsh:
------
Configures the NuttShell (nsh) located at examples/nsh. This
configuration is focused on network testing.
bmp180:
------
This is a configuration example for the BMP180 barometer sensor. This
sensor works with I2C, you need to do the next connections:
BMP180 VIN -> Board 3.3V
BMP180 GND -> Board GND
BMP180 SCL -> Board PB6 (Arduino header D1)
BMP180 SDA -> Board PB7 (Arduino header D0)
This example is configured to work with the USBNSH instead of UART NSH, so
the console will be shown over the USB_OTG1 connector.
On the console, type "ls /dev " and if the registration process goes fine,
you should see a device called "press0". Now execute the app
BMP180 to see the ambient pressure value.
dac:
---
This is a configuration example to use the DAC1 of the board.The DAC1 is attached
to the PA4 pin (Arduino header D10).
This example is configured to work with the USBNSH instead of UART NSH, so
the console will be shown over the USB_OTG1 connector.
On the console, type "ls /dev " and if the registration process goes fine,
you should see a device called "dac0". Now execute the app
dac put a value at the output.
ina219:
------
This is a configuration example for the INA219 DC current sensor. This
sensor works with I2C, you need to do the next connections:
INA219 VIN -> Board 3.3V
INA219 GND -> Board GND
INA219 SCL -> Board PB6 (Arduino header D1)
INA219 SDA -> Board PB7 (Arduino header D0)
This example is configured to work with the USBNSH instead of UART NSH, so
the console will be shown over the USB_OTG1 connector.
On the console, type "ls /dev " and if the registration process goes fine,
you should see a device called "ina219". Now execute the app
ina219 to see the ambient pressure value.
timer:
-----
This configuration set the proper configuration to use the timer1 of the board.
This example is configured to work with the USBNSH instead of UART NSH, so
the console will be shown over the USB_OTG1 connector.
On the console, type "ls /dev " and if the registration process goes fine,
you should see a device called "timer1".
