System Clock
142+
============
143+
144+
The PIC32CXSG41 MCU is configured to use the 32.768 kHz external oscillator
145+
with the on-chip PLL generating the 48 MHz system clock.
146+
147+
Serial Port
148+
===========
149+
150+
The PIC32CXSG41 MCU has 8 SERCOM based USARTs with one configured as USARTs in
151+
this BSP. SERCOM4 is the default Zephyr console.
152+
153+
- SERCOM4 115200 8n1 connected to the onboard Microchip Embedded Debugger (EDBG)
154+
155+
PWM
156+
===
157+
158+
The PIC32CXSG41 MCU has 5 TCC based PWM units with up to 6 outputs each and a period
159+
of 24 bits or 16 bits. If PWM TCC is enabled then LED0 is
160+
driven by TCC0 instead of by GPIO.
161+
162+
SPI Port
163+
========
164+
165+
The PIC32CXSG41 MCU has 8 SERCOM based SPIs.
166+
167+
I2C Port
168+
========
169+
170+
The PIC32CXSG41 MCU has 5 SERCOM based I2Cs. On the Microchip PIC32CXSG41 Curiosity Ultra,
171+
SERCOM7 is connected to a AT24MAC402 EEPROM.
172+
173+
Programming and Debugging
174+
*************************
175+
176+
The Microchip PIC32CXSG41 Curiosity Ultra comes with a Microchip Embedded Debugger (EDBG).
177+
This provides a debug interface to the PIC32CXSG41 chip and is supported by OpenOCD.
178+
179+
Flashing
180+
========
181+
182+
#. Build the Zephyr kernel and the ``hello_world`` sample application:
183+
184+
.. zephyr-app-commands::
185+
:zephyr-app: samples/hello_world
186+
:board: pic32cxsg41_cult
187+
:goals: build
188+
:compact:
189+
190+
#. Connect the Microchip PIC32CXSG41 Curiosity Ultra to your host computer using the USB debug
191+
port.
192+
193+
#. Run your favorite terminal program to listen for output. Under Linux the
194+
terminal should be :code:`/dev/ttyACM0`. For example:
195+
196+
.. code-block:: console
197+
198+
$ minicom -D /dev/ttyACM0 -o
199+
200+
The -o option tells minicom not to send the modem initialization
201+
string. Connection should be configured as follows:
202+
203+
- Speed: 115200
204+
- Data: 8 bits
205+
- Parity: None
206+
- Stop bits: 1
207+
208+
#. To flash an image:
209+
210+
.. zephyr-app-commands::
211+
:zephyr-app: samples/hello_world
212+
:board: pic32cxsg41_cult
213+
:goals: flash
214+
:compact:
215+
216+
You should see "Hello World! pic32cxsg41_cult" in your terminal.
217+
218+
