[hide]Download and build the project
- Get From: http://ics.nxp.com/support/documents/?type=software
- LPC175x and LPC176x CMSIS-Compliant Standard Peripheral Firmware Driver Library (GNU, Keil, IAR) (Jun 21, 2011) lpc17xx.cmsis.driver.library.zip
- Keil project at folder
in my laptop F:\opt\WORKSPACES\keil_arm\lpc17xx.cmsis.driver.library\Examples\I2C\Monitor\Keil or in other computer: ...\lpc17xx.cmsis.driver.library\Examples\I2C\Monitor\Keil
- info for project on
- abstract.txt, inside the project directory
- Available for both KEIL and IAR
- Built successfully 400px
- With Keil uVision V4.14.4.0 free version
Testing
- With mbed:
- Source changed for I2C1 instead I2C0
- mbed pin10=SCL1 destroys SCL line of Arduino:
- Pulls high
- Next test:
- Use LPCxpresso board
- use unchanged source
- Pins for I2C0 are available
Hardware setup
- lpc1768-pinout-with-labelled-mbed-pins
- I2C connection:
- For I2C0:
- SDA -> P0.27
- SCL -> P0.28
Hex to bin
For mbed programing a .bin file is needed, so we have to convert the .hex produced from compiler to .bin
Python intelhex
- Alexander Belchenko's
- YES IT WORKS
- like python :)
- Python Hex to BIN utility http://bialix.com/intelhex/0.8/README.html
- Download intelhex-0.8.6.zip
- Worked from command prompt:
- But not from freeCommander
python intelhex.py i2c_monitor.hex
- Windows system variable PYTHONPATH had to be set to:
C:\PYTHON27;C:\PYTHON27\DLLs;C:\PYTHON27\LIB;C:\PYTHON27\LIB\LIB-TK
- as advised here
axf to bin
arm-none-eabi-objcopy
- tested:
- From both command prompt and from inside codered
- Produces too large file, something is wrong
- Keil produces .hex and .axf
- To create .bin for use with mbed a comversion needed
- From Codered OutputFormats, how to use arm-none-eabi-objcopy
arm-none-eabi-objcopy -O binary example.axf example.bin
- batch file created and tested

Keil
- tested fromelf
- Asks FLEXLM license file
Keil hex2bin
- not tested
It is old, Have to check if works with ARM
