mouseplay: example HID mouse
2+
============================
3+
4+
## Introduction
5+
6+
This functions like the example app "mouseplay" included with [USB DFU Bootloader for PIC16F1454/5/9](https://github.com/majbthrd/PIC16F1-USB-DFU-Bootloader).
7+
8+
The USB stack source code owes its origins to both [vcp](https://github.com/ataradov/vcp) and [free-dap](https://github.com/ataradov/free-dap). The [vcp](https://github.com/ataradov/vcp) USB stack is newer and more sophisticated, but is not a HID implementation like [free-dap](https://github.com/ataradov/free-dap). Using the two code bases, I made an educated guess at what sort of USB HID implementation the author might have written after written vcp.
9+
10+
The linker memory maps have been adjusted to exclude the first 0x400 bytes so as allow operation with the [USB DFU Bootloader for SAMD11](https://github.com/majbthrd/SAMD11-USB-DFU-Bootloader/).
11+
12+
## Build Requirements
13+
14+
One approach is to use [Rowley Crossworks for ARM](http://www.rowley.co.uk/arm/) to compile this code. It is not free software, but has been my favorite go-to ARM development tool for a decade and counting.
15+
16+
*OR*
17+
18+
Use the Makefile in the make subdirectory. With this approach, the code can be built using only open-source software. In Ubuntu-derived distributions, this is likely achieved with as little as:
19+
20+
```
21+
sudo apt-get install gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential
22+
```
23+
24+
## Customizing
25+
26+
usb_descriptors.c contains the USB VID:PID. All unique USB device implementations must have their own unique USB VID:PID identifiers.
27+
28+
If modifying usb_hid_report_descriptor in usb_hid.c, the USB_HID_REPORT_DESCRIPTOR_LENGTH define in usb_hid.h *MUST* exactly match the new size of usb_hid_report_descriptor.
29+
30+
As with any USB HID device, the HID report size (nominally sent by send_buffer() in main.c) *MUST* exactly match the metadata conveyed in the usb_hid_report_descriptor.
