EIC module consumes a lot of current
Hello,   Have you tried to select the low power 32kHz clock as the clock source? Bit 4 – CKSEL Clock Selection The EIC can be clocked either by GCLK_EIC (when a frequency...

SAMC21 Main clock, peripheral clock and clock domain synchronization
Hello,   The advice Steve gave was spot on, the synchronization of clock domains (mostly) does not have a significant delay. I tested this on a free running timer...

SAMC21 Main clock, peripheral clock and clock domain synchronization
 track the number of iterations required for various clock ratios. What would be a good way of doing this? Toggle pin between the synchronization loops and measure the time...

[NO ASF] Issue with SAMD21 LIN slave implementation on UART using break/sync detection
Update 2 Tested with CPU core clock set to internal 8 MHz clock so that the APBC clock connected to SERCOM is also 8 MHz. Still got the same problem as described in update 1

SAMD21 read/write to NVM [NO ASF]
I have not worked with the NVM myself, but have a look at the caching of data. Datasheet p22.3 Block diagram. It could be that the data you wrote is still in cache or when you...

[NO ASF] Issue with SAMD21 LIN slave implementation on UART using break/sync detection
Update The PID that I sent was 0x06 (0b0110 LBS first), I started testing with other PID´s and found out that PID´s starting with a 1 work ok so 0x0D (0b1101 LBS first) . I...
