For the HS - * examples it also assumes you have a waveshare USB3300 breakout board plugged - * into the ULPI PMOD header on the openh743i-c. - * - * UART Debugging: - * Due to pin conflicts in the HS configuration, this BSP uses USART3 (PD8, PD9). - * As such, you won't be able to use the UART to USB converter on board and will - * require an external UART to USB converter. You could use the waveshare FT232 - * USB UART Board (micro) but any 3.3V UART to USB converter will be fine. - * - * Fullspeed: - * If VBUS sense is enabled, ensure the PA9-VBUS jumper is connected on the core - * board. Connect the PB6 jumper for the LED and the Wakeup - PA0 jumper for the - * button. Connect the USB cable to the USB connector on the core board. - * - * High Speed: - * Remove all jumpers from the openh743i-c (especially the USART1 jumpers as the - * pins conflict). Connect the PB6 jumper for the LED and the Wakeup - PA0 - * jumper for the button. - * - * The reset pin on the ULPI PMOD port is not connected to the MCU. You'll need - * to solder a wire from the RST pin on the USB3300 to a pin of your choosing on - * the openh743i-c board (this example assumes you've used PD14 as specified with - * the ULPI_RST_PORT and ULPI_RST_PIN defines below). - * - * Preferably power the board using the external 5VDC jack. Connect the USB cable - * to the USB connector on the ULPI board. Adjust delays in this file as required. - * - * If you're having trouble, ask a question on the tinyUSB Github Discussion boards. - * - * Have fun! - * -*/ - -//--------------------------------------------------------------------+ -// BOARD DEFINES -//--------------------------------------------------------------------+ - -//LED Pin -#define LED_PORT GPIOB -#define LED_PIN GPIO_PIN_6 -#define LED_STATE_ON 1 - -//ULPI PHY reset pin -#define ULPI_RST_PORT GPIOD -#define ULPI_RST_PIN GPIO_PIN_14 - -// Tamper push-button -#define BUTTON_PORT GPIOA -#define BUTTON_PIN GPIO_PIN_0 -#define BUTTON_STATE_ACTIVE 1 - -// Need external UART to USB converter as USART1 pins conflict with HS ULPI pins -#define UART_DEV USART3 -#define UART_CLK_EN __HAL_RCC_USART3_CLK_ENABLE -#define UART_GPIO_PORT GPIOD -#define UART_GPIO_AF GPIO_AF7_USART3 -#define UART_TX_PIN GPIO_PIN_8 -#define UART_RX_PIN GPIO_PIN_9 - -// VBUS Sense detection -#define OTG_FS_VBUS_SENSE 1 -#define OTG_HS_VBUS_SENSE 0 - - -//--------------------------------------------------------------------+ -// MACRO TYPEDEF CONSTANT ENUM -//--------------------------------------------------------------------+ - -UART_HandleTypeDef uartHandle;
