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;
