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/

Revision:
70:b3a5af880266
Parent:
0:9b334a45a8ff 
Edited DAC routines to allow for the simultaneous use of three channels from two DACs as seen on the STM32F334R8 and STM32F303K8. Edited ADC routines to allow for the simultaneous use of more than one ADC.
