Tutorial Using CoIDE

  • Click the CoIDE icon

  • The welcome page is a convenient entry for “Browse in Repository”, “Create a New Project”, “Open a Project”, refer to “User Guide” and go to “Forum"

  • A wizard window will pop up, enter a name for the project (my project name: LoopbackTest)),You can also modify the Project Path.

  • Choose a model. For example, select ''Chip Model', then click “Next”.

  • Select a chip. For example, select "M0516LBN"

  • Click "Finish". CoIDE automatically generates LoopbackTest.coproj file and one configuration: "LoopbackTest".

  • Click the Repository Button

  • Check a component; for example, select 'GPIOSPIUARTCoX.cookie.M051.configC library''Retarget printf'. CoIDE will automatically check the components, which are depended by the checked component.

Tutorial Using W5500

Change code before compile

  • Select the file "stdio.h/printf.c". You want to use "printf", you have to add as below.

void PrintChar(char c)
/* Send a char like:
while(Transfer not completed);
Transmit a char;
xUARTCharPut(xUART0_BASE,c); // additional items
  • Select the define variable in "ethernet/w5500". You should select interface mode and kind of chip.

#define WIZCHIP 5500 // 5100, 5200, 5500

#if (WIZCHIP == 5500) #define WIZCHIP_ID "W5500\0" // #define WIZCHIP_IO_MODE WIZCHIP_IO_MODE_SPI_FDM #define WIZCHIP_IO_MODE WIZCHIP_IO_MODE_SPI_VDM #include "W5500/w5500.h" <markdown> - Select the define variable in "common/common.h". You can modify the Log Level.

//------------------------------ Etc ------------------------------
#define WIZ_LOG_LEVEL 2 // 0: No print, 1: Error, 2: Error+Log, 3: Error+Log+Debug
