@brief Support for the Atmel SAM D10 Xplained Mini board.
|
||||
|
||||
## Overview
|
||||
|
||||
The `SAMD10 Xplained Mini` is an ultra-low cost evaluation board by Atmel
|
||||
featuring an SoC. The SoC includes a SAMD10 ARM Cortex-M0+ micro-
|
||||
controller. For programming the MCU comes with 4Kb of RAM and 16Kb of flash
|
||||
memory.
|
||||
|
||||
The samd10-xmini is available from various hardware vendors for ~8€ (as of
|
||||
2020 October).
|
||||
|
||||
## Hardware
|
||||
|
||||
|
||||
|
||||
### MCU
|
||||
| MCU | ATSAMD10D14AU |

|
||||
| Datasheet | [Datasheet](http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-42242-SAM-D10_Datasheet.pdf) |
|
||||
| Board Manual | [Board Manual](http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-42387-ATSAMD10-Xplain-Mini_User-Guide.pdf) |
|
||||
|
||||
### User Interface
|
||||
|
||||
1 User button and 1 LED:
|
||||
|
||||
| Device | PIN |
|
||||
|:------ |:---- |
|
||||
| LED0 | PA09 |
|
||||
| SW0 | PA25 |
|
||||
|
||||
## Flashing the device
|
||||
|
||||
Connect the device to your Micro-USB cable using the port labeled as *DEBUG
|
||||
USB*.
|
||||
|
||||
The standard method for flashing RIOT to the samd10-xmini is using EDBG.
|
||||
|
||||
On Linux you will have to add a **udev** rule for hidraw, like
|
||||
```
|
||||
echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"' \
|
||||
| sudo tee -a /etc/udev/rules.d/99-usb.rules
|
||||
sudo service udev restart
|
||||
```
|
||||
|
||||
Then you can flash the device as usual
|
||||
|
||||
```
|
||||
make BOARD=samd10-xmini flash
|
||||
```
|
||||
|
||||
## Known Issues / Problems
|
||||
|
||||
### I2C
|
||||
|
||||
The I2C pins on the board do not have any pull-ups connected to them.
|
||||
That means that running e.g. `i2c_scan` without any I2C slaves connected
|
||||
will run into timeouts.

* @name External oscillator and clock configuration
|

*
|
||||
* There are three choices for selection of CORECLOCK:
|
||||
*
|
||||
* - usage of the 48 MHz DFLL fed by external oscillator running at 32 kHz
|
||||
* - usage of the PLL fed by the internal 8MHz oscillator divided by 8
|
||||
* - usage of the internal 8MHz oscillator directly, divided by N if needed
|
||||
*
|
||||
*
|
||||
* The PLL option allows for the usage of a wider frequency range and a more
|
||||
* stable clock with less jitter. This is why this option is default.
|
||||
*
|
||||
* The target frequency is computed from the PLL multiplier and the PLL divisor.
|
||||
* Use the following formula to compute your values:
|
||||
*
|
||||
* CORECLOCK = ((PLL_MUL + 1) * 1MHz) / PLL_DIV
|
||||
*
|
||||
* NOTE: The PLL circuit does not run with less than 32MHz while the maximum PLL
|
||||
* frequency is 96MHz. So PLL_MULL must be between 31 and 95!
|
||||
*
|
||||
*
|
||||
* The internal Oscillator used directly can lead to a slightly better power
|
||||
* efficiency to the cost of a less stable clock. Use this option when you know
|
||||
* what you are doing! The actual core frequency is adjusted as follows:
|
||||
*
|
||||
* CORECLOCK = 8MHz / DIV
|
||||

* NOTE: A core clock frequency below 1MHz is not recommended
