HPM6750 Review of Pioneer Semiconductor Step 3 (RT-Thread + TinyUSB) [Copy link]

 

Recently, I saw that RT-Thread Studio has a major version update (V4.1), and added support for the TinyUSB software package. TinyUSB has been used in my previous projects, so this section uses RT-Thread Studio to create a project.

TinyUSB is an open source cross-platform USB host/device stack for embedded systems, designed to achieve memory safety without dynamic allocation and thread safety by delaying all interrupt events, which are then processed in non-ISR task functions. TinyUSB supports chips from many manufacturers such as ST, NXP, MicroChip, etc. Espressif's ESP32 S series also supports USB development using TinyUSB.

The porting and operation of TinyUSB are very simple, and it is even simpler when paired with RT-Thread Studio.

1. Install the required SDK

2. Add TinyUSB software package to the project

3. Enable USB Device in Hardware Configuration

4. Adjust the TinyUSB software package configuration

5. Create a new hid_test file and write the code to test the HID communication

#include <rtthread.h>
#include <rtdevice.h>
#include "rtt_board.h"
#include <tusb.h>

struct __attribute __ ((__packed__) ) reportHID_t {
// uint8_t reportId ;
int8_t

struct reportHID_t reportHID;
static void hid_test_entry(void *parameter)
{
(void) parameter;
static uint32_t send_failed_cnt;
reportHID.X = 127;
reportHID.Y = 127;
reportHID.Z = -127;
reportHID.Rx = 0;
reportHID.Ry = 127;
reportHID.Rz = 127;
reportHID.button = 1;
uint8_t res = false;
while (1)
{
if (tud_suspended())
{
rt_kprintf("tud_suspended!!!\r\n");
tud_remote_wakeup();
}
else
{
res = tud_hid_report(3,(uint8_t*)&reportHID, 11);
if(reportHID.button<2147483648)
{
reportHID.button*=2;
}
else
{
reportHID.button = 1;
}
if(!res)
{
send_failed_cnt++;
rt_kprintf("Send Failed :%d Times\r\n",send_failed_cnt);
}

}
rt_thread_mdelay(500);
}
}

static int init_hid_test(void)
{
rt_thread_t hid_test;

hid_test = rt_thread_create("hid test", hid_test_entry, RT_NULL,
PKG_TINYUSB_STACK_SIZE,
PKG_TINYUSB_THREAD_PRIORITY, 10);
if (hid_test == RT_NULL)
{
rt_kprintf("Fail to create HID Test thread");
return -1;
}
rt_kprintf("init_hid_test create success!!!\r\n");
rt_thread_startup(hid_test);
return 0;
}

MSH_CMD_EXPORT(init_hid_test, init hid test)

6. Compile, download and test

7.HID is working according to our program logic. Done!

The transplantation and operation of TinyUSB seems to be not complicated

rt supports quite fast.
