<p>CMSIS-DAP Firmware uses USB HID as interface to host computer.

|

|
|
<p>CMSIS-DAP Firmware uses USB HID as interface to host computer. </p>
|
||
|
|
<p>The CMSIS-DAP Firmware uses MDK Professional middleware components to access the USB peripheral of the microcontroller. The CMSIS-DAP Firmware uses the USB Human Interface Device (HID) class that does not require any USB driver development for the host computer. However it is important to provide correct configuration information for the USB Peripheral as described in this section.</p>
|
||
|
|
<p>The following steps describe how to change and configure the USB peripheral in the CMSIS-DAP Firmware project:</p>
|
||
|
|
<ol type="1">
|
||
|
|
<li>In the <b>Project Window</b>, the group <b>USB</b> contains USB interface with the relevant configuration files.</li>
|
||
|
|
<li>Open the file <b>usb_config_0.c</b> in the editor and select <b>Configuration Wizard</b> as edit mode; then change the following settings:<ul>
|
||
|
|
<li><b>USB Device 0 - High-speed</b>: enable this option only for a high-speed USB peripheral; disable for full-speed USB.</li>
|
||
|
|
<li>Update <b>Device Settings - Vendor ID</b> which is provided by the <a href="http://www.usb.org/developers/vendor/" target="_blank">USB Implementers Forum</a>.</li>
|
||
|
|
<li>Update <b>Device Settings - Product ID</b> to provide a unique identification for the Debug Unit.</li>
|
||
|
|
<li>Update <b>Device Settings - Device Release Number</b> to indicate the revision of the adaptation.</li>
|
||
|
|
<li>Update <b>String Settings - Manufacturer String</b> to reflect the vendor of the Debug Unit. This setting should match the <b>Vendor ID</b>.</li>
|
||
|
|
<li>Update <b>String Settings - Product String</b> to indicate the Debug Unit. Note that "CMSIS-DAP" must be part of that string to allow identification by debuggers.</li>
|
||
|
|
<li>Optionally each Debug Unit may provide a unique <b>Serial Number String</b>. If the <b>String Settings - Serial Number String</b> is not provided, only one Debug Unit can be connected at the same time to a host computer since it is impossible to identify multiple Debug Units.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
</ol>
|
||
|
|
<p>The CMSIS-DAP Firmware can be also part of a USB composite device. If this case, the <b>HID Interface String</b> must contain the sub-string <b>CMSIS-DAP</b>. The <b>HID Interface String</b> is configured in the file USBD_Config_HID_0.h under the category <b>Human Interface Device Class Settings</b>.</p>
|
||
|
|
<dl class="section note"><dt>Note</dt><dd><ul>
|
||
|
|
<li>The USB Device setting high-speed / full-speed USB must be reflected in the <b>DAP_config.h</b> file as described under <a class="el" href="group__DAP__Config__gr.html">Firmware Configuration</a>.</li>
|
||
|
|
<li>The <b>String Settings - Product String</b> must contain "CMSIS-DAP" somewhere in the string. This is used by the debuggers to identify a CMSIS-DAP compliant Debug Unit that is connected to a host computer.</li>
