| mbed_official | 205:c41fc65bcfb4 | 20 | The UART HAL driver can be used as follows: |
| mbed_official | 205:c41fc65bcfb4 | 21 | |
| mbed_official | 205:c41fc65bcfb4 | 22 | (#) Declare a UART_HandleTypeDef handle structure. |
| mbed_official | 205:c41fc65bcfb4 | 23 | |
| mbed_official | 205:c41fc65bcfb4 | 24 | (#) For the UART RS485 Driver Enabled mode, initialize the UART registers |
| mbed_official | 205:c41fc65bcfb4 | 25 | by calling the HAL_RS485Ex_Init() API. |
