README ====== 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 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.
