-
-For more information visit http://libopencm3.org
-
-The examples are meant as starting points for different subsystems on multitude

-
-The makefiles are generally useable for your own projects with

-
-For flashing the 'miniblink' example (after you built libopencm3 and the
-examples by typing 'make' at the top-level directory) onto the Olimex
-STM32-H103 eval board (ST STM32F1 series microcontroller), you can execute:
-
- $ cd examples/stm32/f1/stm32-h103/miniblink
- $ make flash
-
-The Makefiles of the examples are configured to use a certain OpenOCD
-flash programmer, you might need to change some of the variables in the
-Makefile if you use a different one.
-
-You can also flash manually like this:
-
- $ openocd -f interface/jtagkey-tiny.cfg -f target/stm32f1x.cfg
- $ telnet localhost 4444
- > reset halt
- > flash write_image erase foobar.hex
- > reset
-
-Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
-replace "stm32f1x.cfg" with your respective config file. Replace "foobar.hex"
-with the file name of the image you want to flash.

+[![Build Status](https://travis-ci.org/libopencm3/libopencm3-examples.svg?branch=master)](https://travis-ci.org/libopencm3/libopencm3-examples)
+
+[![Gitter channel](https://badges.gitter.im/libopencm3/discuss.svg)](https://gitter.im/libopencm3/discuss)
+
+This repository contains assorted example projects for libopencm3.
+
+The libopencm3 project aims to create an open-source firmware library for
+various ARM Cortex-M microcontrollers.
+
+For more information visit http://libopencm3.org
+
+The examples are meant as starting points for different subsystems on multitude
+of platforms. If you're just looking to test your build environment and hardware,
+the [libopencm3-miniblink](https://github.com/libopencm3/libopencm3-miniblink) 
+may be more useful, as it covers _many_ more boards, but it is much more limited.
+
+Feel free to add new examples and send them to us either via the mailinglist or
+preferably via a github pull request.
+
+## Usage
+
+You _must_ run "make" in the top level directory first.  This builds the
+library and all examples.  If you're simply hacking on a single example after
+that, you can type "make clean; make" in any of the individual project
+directories later.
+
+For more verbose output, to see compiler command lines, use "make V=1"
+For insanity levels of verboseness, use "make V=99"
+
+The makefiles are generally useable for your own projects with
+only minimal changes for the libopencm3 install path (See Reuse)
+
+## Make Flash Target
+
+Please note, the "make flash" target is complicated and not always self-consistent.  Please see: https://github.com/libopencm3/libopencm3-examples/issues/34
+
+For flashing the 'miniblink' example (after you built libopencm3 and the
+examples by typing 'make' at the top-level directory) onto the Olimex
+STM32-H103 eval board (ST STM32F1 series microcontroller), you can execute:
+
+    cd examples/stm32/f1/stm32-h103/miniblink
+    make flash V=1
+
+The Makefiles of the examples are configured to use a certain OpenOCD
+flash programmer, you might need to change some of the variables in the
+Makefile if you use a different one.
+
+To program via a Black Magic Probe, simply provide the serial port, eg:
+
+    cd examples/stm32/f1/stm32-h103/miniblink
+    make flash BMP_PORT=/dev/ttyACM0
+
+To program via texane/stlink (st-flash utility), use the special target:
+
+    cd examples/stm32/f1/stm32vl-discovery/miniblink
+    make miniblink.stlink-flash
+
+If you rather use GDB to connect to the st-util you can provide the STLINK\_PORT
+to the flash target.
+
+    cd examples/stm32/f1/stm32vl-discovery/miniblink
+    make flash STLINK_PORT=:4242
+
+## Flashing Manually
+You can also flash manually. Using a miriad of different tools depending on
+your setup. Here are a few examples.
+
+### OpenOCD
+
+    openocd -f interface/jtagkey-tiny.cfg -f target/stm32f1x.cfg
+    telnet localhost 4444
+    reset halt
+    flash write_image erase foobar.hex
+    reset
+
+Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
+replace "stm32f1x.cfg" with your respective config file. Replace "foobar.hex"
+with the file name of the image you want to flash.
+
+### Black Magic Probe
+
+    cd examples/stm32/f1/stm32vl-discovery/miniblink
+    arm-none-eabi-gdb miniblink.elf
+    target extended_remote /dev/ttyACM0
+    monitor swdp_scan
+    attach 1
+    load
+    run
+
+To exit the gdb session type `<Ctrl>-C` and `<Ctrl>-D`. It is useful to add the
+following to the .gdbinit to make the flashing and debugging easier:
+
+    set target-async on
+    set confirm off
+    set mem inaccessible-by-default off
+    #set debug remote 1
+    tar ext /dev/ttyACM0
+    mon version
+    mon swdp_scan
+    att 1
+
+Having this in your .gdbinit boils down the flashing/debugging process to:
+
+    cd examples/stm32/f1/stm32vl-discovery/miniblink
+    arm-none-eabi-gdb miniblink.elf
+    load
+    run
+
+### ST-Link (st-util)
+
+This example uses the st-util by texane that you can find on [GitHub](https://github.com/texane/stlink).
+
+    cd examples/stm32/f1/stm32vl-discovery/miniblink
+    arm-none-eabi-gdb miniblink.elf
+    target extended-remote :4242
+    load
+    run
+
+## Reuse
+
+If you want to use libopencm3 in your own project, the _easiest_ way is
+to use the template repository we created for this purpose.
+
+See https://github.com/libopencm3/libopencm3-template

-This program exercises the I2C peripheral on Jellybean's LPC43xx.  You can
-scope SCL on P6 pin 3 and SDA on P6 pin 5.  If Lemondrop is connected, LED1

-Required Lemondrop -> Jellybean connections:

-SCL: Lemondrop P7 pin 3 -> Jellybean P6 pin 3
-SDA: Lemondrop P7 pin 5 -> Jellybean P6 pin 5
-VCC: Lemondrop P4 pin 2, 4, or 6 -> Jellybean P17 pin 2, 4, or 6

-By default (CPSDVSR=0 => Means MAX Divisor)

-Theory:
-SCR=0,  CPSDVSR=32 => 288MHz / (32*(0+1) = 9MHz

-SCR=64, CPSDVSR=2 => 288MHz / (2*(64+1)) = 2.2154MHz
-SCR=128, CPSDVSR=2 => 288MHz / (2*(128+1)) = 1.116MHz

+This example program sends a message "Pass: n" with increasing number n
+from 0 to 200 on USART1 serial line of ST STM32F0DISCOVERY eval board.
+
+The sending is done using newlib library in a blocking way.
