Hello,
I'm trying to follow the example provided in the "Infineon-XMC1400_Boot_Kit_GettingStarted-GS-v01_00-EN.pdf".
I followed the instructions in the presentation to the letter and made it all the way to be build step for the "XMC1400_BlinkyMCAN" example.
The tool is flagging the lines which read:
led_config.mode = XMC_GPIO_MODE_OUTPUT_PUSH_PULL;
led_TX_config.mode = XMC_GPIO_MODE_OUTPUT_PUSH_PULL;
led_RX_config.mode = XMC_GPIO_MODE_OUTPUT_PUSH_PULL;
The tool revealed that these led_ variables as undeclared. Which, so far as I can tell is true. What I don't see is any information in the example presentation where these variables are declared.
Is it just me? Or does there seem to be code missing in the example?
The tool also complained about the two lines:
//.enable_automatic_dco1_calibration = true,
//.clock_sync = XMC_SCU_CLOCK_SYNC_CLKSRC_OSCHP,
and rightfully so. These members don't exist in the definition for XMC_SCU_CLOCK_CONFIG_t.
Again, am I missing something simple?
Thank you in advance for your assistance.
