| 140 | +System Clock |
| 141 | +============ |
| 142 | + |
| 143 | +The PIC32CXSG41 MCU is configured to use the 32.768 kHz external oscillator |
| 144 | +with the on-chip PLL generating the 48 MHz system clock. |
| 145 | + |
| 146 | +Serial Port |
| 147 | +=========== |
| 148 | + |
| 149 | +The PIC32CXSG41 MCU has 8 SERCOM based USARTs with one configured as USARTs in |
| 150 | +this BSP. SERCOM4 is the default Zephyr console. |
| 151 | + |
| 152 | +- SERCOM4 115200 8n1 connected to the onboard Microchip Embedded Debugger (EDBG) |
| 153 | + |
| 154 | +PWM |
| 155 | +=== |
| 156 | + |
| 157 | +The PIC32CXSG41 MCU has 5 TCC based PWM units with up to 6 outputs each and a period |
| 158 | +of 24 bits or 16 bits. If PWM TCC is enabled then LED0 is |
| 159 | +driven by TCC0 instead of by GPIO. |
| 160 | + |
| 161 | +SPI Port |
| 162 | +======== |
| 163 | + |
| 164 | +The PIC32CXSG41 MCU has 8 SERCOM based SPIs. |
| 165 | + |
| 166 | +I2C Port |
| 167 | +======== |
| 168 | + |
| 169 | +The PIC32CXSG41 MCU has 5 SERCOM based I2Cs. On the Microchip PIC32CXSG41 Curiosity Ultra, |
| 170 | +SERCOM7 is connected to a AT24MAC402 EEPROM. |
| 171 | + |
| 172 | +Programming and Debugging |
| 173 | +************************* |
| 174 | + |
| 175 | +The Microchip PIC32CXSG41 Curiosity Ultra comes with a Microchip Embedded Debugger (EDBG). |
| 176 | +This provides a debug interface to the PIC32CXSG41 chip and is supported by OpenOCD. |
| 177 | + |
| 178 | +Flashing |
| 179 | +======== |
| 180 | + |
| 181 | +#. Build the Zephyr kernel and the ``hello_world`` sample application: |
| 182 | + |
| 183 | + .. zephyr-app-commands:: |
| 184 | + :zephyr-app: samples/hello_world |
| 185 | + :board: pic32cxsg41_cult |
| 186 | + :goals: build |
| 187 | + :compact: |
| 188 | + |
| 189 | +#. Connect the Microchip PIC32CXSG41 Curiosity Ultra to your host computer using the USB debug |
| 190 | + port. |
| 191 | + |
| 192 | +#. Run your favorite terminal program to listen for output. Under Linux the |
| 193 | + terminal should be :code:`/dev/ttyACM0`. For example: |
| 194 | + |
| 195 | + .. code-block:: console |
| 196 | +
|
| 197 | + $ minicom -D /dev/ttyACM0 -o |
| 198 | +
|
| 199 | + The -o option tells minicom not to send the modem initialization |
| 200 | + string. Connection should be configured as follows: |
| 201 | + |
| 202 | + - Speed: 115200 |
| 203 | + - Data: 8 bits |
| 204 | + - Parity: None |
| 205 | + - Stop bits: 1 |
| 206 | + |
| 207 | +#. To flash an image: |
| 208 | + |
| 209 | + .. zephyr-app-commands:: |
| 210 | + :zephyr-app: samples/hello_world |
| 211 | + :board: pic32cxsg41_cult |
| 212 | + :goals: flash |
| 213 | + :compact: |
| 214 | + |
| 215 | + You should see "Hello World! pic32cxsg41_cult" in your terminal. |
