From: ATMEL AT91SAM7S512 AT91SAM7S256 AT91SAM7S128 AT91SAM7S64 AT91SAM7S321 AT91SAM7S32 handbook
What core does the AT91SAM7S64 use?
It uses an ARM7TDMIe core with Thumb support.
How much Flash memory is available on the AT91SAM7S64?
The microcontroller provides 64 KB of internal Flash memory.
How do I turn on an LED on the AT91SAM7S64?
Write the LED mask to the PIOA_SODR register, e.g. *AT91C_PIOA_SODR = LED1; which sets the LED pin high.
How can I read an analog value from the ADC?
Read the ADC channel data register, mask the lower 10 bits and scale the result, e.g. EXT_AD_Val[0] = (*AT91C_ADC_CDR0) & 0x3ff;
