9.2 Including Resources in Non-OS Scheduler
In the sample program, it is composed of HCD, MGR, HUB, HMSCD, HMSDD, APL, and the scheduler.
FAT file system library (TFAT) uses Renesas M3S-TFAT-Tiny-RX

Scheduler Setting
When the non OS scheduler is used, the resource registration such as task ID, mailbox ID, and memory pool ID sets the
scheduler macro definition with r_usbc_cKernelId.h as follows.
/* Host Sample Task */
#define USB_HMSC_TSK USBC_TID_4 /* Task ID */
#define USB_HMSC_PRI USBC_PRI_3 /* Priority */
#define USB_HMSC_MBX USB2_HMSC_TSK /* Mailbox ID */
#define USB_HMSC_MPL USB2_HMSC_TSK /* Memorypool ID */
/* Host Sample Task */
#define USB_HSTRG_TSK USBC_TID_5 /* Task ID */
#define USB_HSTRG_PRI USBC_PRI_3 /* Priority */
#define USB_HSTRG_MBX USB2_HSTRG_TSK /* Mailbox ID */
#define USB_HSTRG_MPL USB2_HSTRG_TSK /* Memorypool ID */
/* Host Sample Task */
#define USB_HMSCSMP_TSK USBC_TID_6 /* Task ID */
#define USB_HMSCSMP_PRI USBC_PRI_4 /* Priority */
#define USB_HMSCSMP_MBX USB_HMSCSMP_TSK /* Mailbox ID */
#define USB_HMSCSMP_MPL USB_HMSCSMP_TSK /* Memorypool ID */
9.2.2 Task Priority setting
The task priority level is set by the R_usbc_cstd_SetTaskPri() function.
In the usb_hmsc_SetTaskPri () function of r_usb_HMSC_apl.c, the task priority level is set as follows.
void usb_hmsc_SetTaskPri
(void)
{
R_usbc_cstd_SetTaskPri(USB_HCD_TSK, USB_HCD_PRI);
R_usbc_cstd_SetTaskPri(USB_MGR_TSK, USB_MGR_PRI);
R_usbc_cstd_SetTaskPri(USB_HUB_TSK, USB_HUB_PRI);
R_usbc_cstd_SetTaskPri(USB_HMSC_TSK,
USB_HMSC_PRI);
R_usbc_cstd_SetTaskPri(USB_HSTRG_TSK, USB_HSTRG_PRI);
R_usbc_cstd_SetTaskPri(USB_HMSCSMP_TSK, USB_HMSCSMP_PRI);
}
These resources are defined in the file r_usbc_cKernelId.h .
