|
********
|
|
|
|
The OLIMEX-STM32-H103 is a simple development board based on the
|
|
STMicroelectronics STM32F103RBT6 ARM Cortex-M3 CPU, with all the MCU pins
|
|
populated and accessible through two male 26-pin connectors.

|
|
- ADC_1: PA1
|
|
|
|
System Clock
|
|
------------
|
|
|
|
The on-board 8 MHz crystal is used to produce a 72 MHz system clock with PLL.
|
|
|
|
Serial Port
|
|
-----------
|
|
|
|
The board has 3 U(S)ARTs, UART1 and UART2 are enabled by default, with UART2
|
|
used as Zephyr's console. Default settings are 115200 8N1.
|
|
|
|
On-Board LEDs
|
|
-------------
|
|
|
|
The board has one on-board green LED that is connected to PC12, which
|
|
is active low.
|
|
|
|
There is also a red power LED neither connected nor controlled by the MCU.
|
|
|
|
On-Board Button
|
|
---------------
|
|
|
|
The board has one user button connected to PA0.
|
|
|
|
USB
|
|
---
|
|
|
|
USB is not enabled by default, however PC4 is configured by default as an ADC
|
|
input to sense the USB voltage (see schematic). It is possible to disconnect
|
|
it by desoldering the appropriate pad in the PCB.
|
|
|
|
The board uses PC11 to disconnect the pull-up resistor on the USB-DP line.

Programming and Debugging
|
|
*************************
|
|
|
|
This board does not include any embedded debug tool interface, instead you
|
|
will have to use an external probe connected to the available 20-pin JTAG
|
|
connector to program and debug the board. Both JTAG and SWD are supported.
|
|
|
|
By default when using ``west debug`` ST-Link will be used with OpenOCD's
|
|
SWD transport, but it is also possible to use JTAG with the Olimex ARM-USB-OCD-H
|
|
probe, for instance. For the latter, you should replace the file ``openocd.cfg``
|
|
by ``openocd_olimex_jtag.cfg``, located in the board's support directory.
|
|
|
|
Flashing
|
|
========
|
|
|
|
Here is an example for the :ref:`button-sample` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/button
|
|
:board: olimex_stm32_h103
|
|
:goals: build flash
|
|
|
|
Debugging
|
|
=========
|
|
|
|
You can debug an application in the usual way. Here is an example for the
|
|
:ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: olimex_stm32_h103
|
|
:maybe-skip-config:
|
|
:goals: debug
