Hello everybody,

 

I am using the microcontroler LPC1769 and I communicate with a smartphone thanks to the protocole bulk and the function send_data(). This function comes from "Example_Keyboarddevice", available on the NXP website. I would like to send pieces of data every 10 microseconds. I only manage to send it every 1ms with the bulk protocole. I tried to change some parameters but i still cant transmit data as fast as I want.

Do you know if it's possible the change the data transfer, and how I could procede?

Best regards,

Pac.
