philippe s. / mbed-dev

mbed library sources. Supersedes mbed-src. Fixes analogIn and analogOut problems for TARGET_STM32F3. Tested on NUCLEO-F303K8, using 3 analogout and 7 analogin channels simultaneously. Added ability for STM32F334R8 and STM32F303K8 to use all three channels of DAC simultaneously. https://developer.mbed.org/users/StevieWray/code/mbed-dev/ Added ability for TARGET_STM32F3 to use more than one ADC simultaneously. https://developer.mbed.org/questions/67997/NUCLEO-F303K8ADC/
