mbed_official 76:aeb1df146756 8 * functionalities of the operational amplifiers (opamp) peripheral:
mbed_official 76:aeb1df146756 9 * + Initialization and configuration

mbed_official 76:aeb1df146756 15 ==============================================================================
mbed_official 76:aeb1df146756 16 [..] The device integrates three independent rail-to-rail operational amplifiers
mbed_official 76:aeb1df146756 17 OPAMP1, OPAMP2 and OPAMP3:
mbed_official 76:aeb1df146756 18 (+) Internal connections to the ADC.
mbed_official 76:aeb1df146756 19 (+) Internal connections to the DAC.
mbed_official 76:aeb1df146756 20 (+) Internal connection to COMP1 (only OPAMP3).
mbed_official 76:aeb1df146756 21 (+) Internal connection for unity gain (voltage follower) configuration.
mbed_official 76:aeb1df146756 22 (+) Calibration capability.
mbed_official 76:aeb1df146756 23 (+) Selectable gain-bandwidth (2MHz in normal mode, 500KHz in low power mode).
mbed_official 76:aeb1df146756 24 [..]
mbed_official 76:aeb1df146756 25 (#) COMP AHB clock must be enabled to get write access
mbed_official 76:aeb1df146756 26 to OPAMP registers using
mbed_official 76:aeb1df146756 27 (#) RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE)
mbed_official 76:aeb1df146756 28
mbed_official 76:aeb1df146756 29 (#) Configure the corresponding GPIO to OPAMPx INP, OPAMPx_INN (if used)
mbed_official 76:aeb1df146756 30 and OPAMPx_OUT in analog mode.
mbed_official 76:aeb1df146756 31
mbed_official 76:aeb1df146756 32 (#) Configure (close/open) the OPAMP switches using OPAMP_SwitchCmd()
mbed_official 76:aeb1df146756 33
mbed_official 76:aeb1df146756 34 (#) Enable the OPAMP peripheral using OPAMP_Cmd()
mbed_official 76:aeb1df146756 35
mbed_official 76:aeb1df146756 36 -@- In order to use OPAMP outputs as ADC inputs, the opamps must be enabled
mbed_official 76:aeb1df146756 37 and the ADC must use the OPAMP output channel number:
mbed_official 76:aeb1df146756 38 (+@) OPAMP1 output is connected to ADC channel 3.
mbed_official 76:aeb1df146756 39 (+@) OPAMP2 output is connected to ADC channel 8.
mbed_official 76:aeb1df146756 40 (+@) OPAMP3 output is connected to ADC channel 13 (SW1 switch must be closed).
