Hello, I'm certainly going to buy a foxboard but I have some questions...: I want to send (with the ttyS3 serial port at 250000 baud) 512 bytes (loaded in RAM), make a 88us break, 512 bytes, make a 88us break.... again and again in a background task.
- What about the CPU load ? (I want to make other task in the same time : other serial port, I2C, HD44780 driver, usb pen driver, web server...) - Will the fact of using an external chip (uc or FPGA) linked to the fox board with parallel port reduce the CPU load ? - Do you see another way to do that ? Thank you !
