Erfaringer er det, man får, når man ikke får, hvad man vil have.
The Atmel | SMART SAM D20 devices provide the following features: In-system
programmable Flash, eight-channel Event System, programmable interrupt controller, up to
52 programmable I/O pins, 32-bit real-time clock and calendar, up to eight 16-bit
Timer/Counters (TC). The timer/counters can be configured to perform frequency and
waveform generation, program execution timing or input capture with time and frequency
measurement of digital signals. The TCs can operate in 8- or 16-bit mode, or be cascaded
to form a 32-bit TC. The series provide up to six Serial Communication Modules (SERCOM)
that each can be configured to act as an USART, UART, SPI and I2
C up to 400kHz; up to
twenty-channel 350ksps 12-bit ADC with programmable gain and optional oversampling
and decimation supporting up to 16-bit resolution, one 10-bit 350ksps DAC, two analog
comparators with window mode, Peripheral Touch Controller supporting up to 256 buttons,
sliders, wheels, and proximity sensing; programmable Watchdog Timer, brown-out detector
and power-on reset, and two-pin Serial Wire Debug (SWD) program and debug interface.
