| mbed_official | 157:90e3acc479a2 | 57 | This driver provides functions to configure and program the OPAMP |
| mbed_official | 157:90e3acc479a2 | 58 | of all STM32F30x devices. |
| mbed_official | 157:90e3acc479a2 | 59 | |
| mbed_official | 157:90e3acc479a2 | 60 | To use the OPAMP, perform the following steps: |
| mbed_official | 157:90e3acc479a2 | 61 | |
| mbed_official | 157:90e3acc479a2 | 62 | (#) Enable the SYSCFG APB clock to get write access to OPAMP |
| mbed_official | 157:90e3acc479a2 | 63 | register using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE); |
| mbed_official | 157:90e3acc479a2 | 64 | |
| mbed_official | 157:90e3acc479a2 | 65 | (#) Configure the OPAMP input in analog mode using GPIO_Init() |
| mbed_official | 157:90e3acc479a2 | 66 | |
| mbed_official | 157:90e3acc479a2 | 67 | (#) Configure the OPAMP using OPAMP_Init() function: |
| mbed_official | 157:90e3acc479a2 | 68 | (++) Select the inverting input |
| mbed_official | 157:90e3acc479a2 | 69 | (++) Select the non-inverting inverting input |
| mbed_official | 157:90e3acc479a2 | 70 | |
| mbed_official | 157:90e3acc479a2 | 71 | (#) Enable the OPAMP using OPAMP_Cmd() function |
