$ make install
This will install the library in /usr/local. If you want to install it
elsewhere, use the following syntax:
This will install the library into /usr/local. (permissions permitting)
$ DESTDIR=/opt make install
If you want to install it elsewhere, use the following syntax:
The recommended location is to install into your toolchain directory, e.g.
/home/someuser/sat for a toolchain built using the summon-arm-toolchain
script from https://github.com/esden/summon-arm-toolchain.
$ make DESTDIR=/opt/libopencm3 install
$ DESTDIR=~/sat make install
If you want to attempt to install into your toolchain, use this:
$ make DETECT_TOOLCHAIN=1 install
Note: If you install this into your toolchain, you don't need to pass
any extra -L or -I flags into your projects. However, this also means
you must NOT pass any -L or -I flags that point into the toolchain. This
_will_ confuse the linker. (ie, for summon-arm-toolchain, do NOT pass
-L/home/user/sat/lib) Common symptoms of confusing
the linker are hard faults caused by branches into arm code.
You can use objdump to check for this in your final elf.

This test sets up the CAN interface on Lisa/M and transmits 8 bites every
100ms. The first byte is being incremented in each cycle. The demo also
receives messages and is displaing the first 4 bits of the first byte on the

This example program sends some characters on USART2 on the
ST STM32L DISCOVERY eval board. (USART2 TX on PA2)
The terminal settings for the receiving device/PC are 38400 8n1.
The sending is done in a blocking way in the code, see the usart_irq example
for a more elaborate USART example.

* (from the EFM32 documentation at
* http://www.energymicro.com/downloads/datasheets), and was seen analogously
