Hi all,
I'm trying to create a custom keyboard with STM32F103C8, for the first version, i use HID class. Then i figured out that i can not update leds status. So, i changed to Custom HID class. And i hit this issue. Seem like i only can send one report after 200ms.
This is my code:
Clear_HID_Report();
keyboardHID.keys[0] = 0x15;
USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, &keyboardHID, sizeof(keyboardHID_t));
HAL_Delay(100);
Clear_HID_Report();
keyboardHID.keys[0] = 0x17;
tmp = USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, &keyboardHID, sizeof(keyboardHID_t));
HAL_Delay(100);
Clear_HID_Report();
keyboardHID.keys[0] = 0x10;
USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, &keyboardHID, sizeof(keyboardHID_t));
HAL_Delay(200);
Clear_HID_Report();
USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, &keyboardHID, sizeof(keyboardHID_t));
�?�?�?�?�?�?�?�?�?�?�?�?�?�?
This code return: 'rm', 't' are missing.
Then i increase the delay time to 200ms for all HAL_Delay, and i receive 'rtm'. Is there anyone can help me?
I event try this
do {
tmp = USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, &keyboardHID, sizeof(keyboardHID_t));
} while (tmp != USBD_OK);�?�?�?
It's not help, too.
