Example
Initialize the mouse HID HOST, and after connecting the mouse, read the cursor's x, y coordinates and button status.
from m5stack import *
from m5ui import *
from uiflow import *
import module
import time
setScreenColor(0x222222)
usb = module.get(module.USBHOST)
usb.max3421e_init(sclk=18, mosi=23, miso=19, cs=5, irq=35)
usb.hid_init()
while True:
usb.hid_poll()
if usb.mouse_button_status(1):
print('mouse button left click')
if usb.mouse_button_status(2):
print('mouse button right click')
if usb.mouse_button_status(4):
print('mouse button center click')
print((str('X:') + str((usb.mouse_cursor_x))))
print((str('Y:') + str((usb.mouse_cursor_y))))

import module
usb = module.get(module.USBHOST)
usb.max3421e_init(sclk=18, mosi=23, miso=19, cs=5, irq=35)- Initialize the USB Module.
usb.hid_init()- Initialize Mouse HID Host
usb.hid_poll()- Refresh the status of the input devices.
usb.mouse_button_status(status):- Get the button status:
- status:
- left:1
- right:2
- left+right:3
- center:4
- left+center:5
- right+center:6
- left+right+center:7
- status:
- Return:
- True/False
usb.mouse_cursor_x
usb.mouse_cursor_y- Get the cursor position of the input device
