I used STM32F103 to send data to the PC via USB CDC at a frequency of 4000Hz, 21 bytes per packet. The code generated by STMCube. And then I found that only 1000 packets can be received per second on Windows7 via serial assistant, but it can normally receive 4000 packets per second on Ubuntu via CuteCOM. How do I achieve the same effect on Windows7? Thank you.
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_USB_DEVICE_Init();
while(1)
{
__WFI();
}
}
void HAL_SYSTICK_Callback(void) //4000Hz
{
CDC_Transmit_FS(buff, 21);
}
I use python to test, and the result is:
