STM CircleOS forum / STM32F10x - FreeRTOS - ADC

Dear Collegue,
I have to use an ADC integrated into the STM32F10x microcontroller.
The firmware application is based of STM32 Peripheral Library and FreeRTOS Porting for STM32 Arm Cortex M3 RTOS.
I have to configure the ADC to operate in single channel continuous conversion mode.
i would select the ouuput data of the ADC with the ADC Interrupt service routine.
I don't know How I can configure the ADC Interrupt and How I can generate an OS Signal in the ADC ISR to start the task.
Can yu help me?
In addition I would like to know if I can use in alternative at the ADC ISR, a DMA to transfer the ADC Output data into the memory without CPU load and How I can do it.

The Primer's CircleOS does touchscreen and battery voltage acquisition by managing ADC in DMA mode. It can be a good example.
Take a look at this page :

Else, you can see the several examples provided with the ST peripheral library on ST website.
