Rs232 Feeding-DE2-70

dma and uart is the interface of NIOS.

if you wanna realize the continuous data ...package... Certainly,fifo is a good choise,you may use the megawizard.

According before content, you may create a .bsf including the sopc and a fifo module at least,and the pio is necessary for transporting data from fifo to nios ,then to uart.

However, a fifo and a module that simulate uart function are well....

if you are farmilar with the nios ,you could use the softcore to realize. Or you choose the logic module...

-------------------------

I need to write or read a package to UART. Package like

0xFF 0xFF 0x01 0x04 0x02 0x2B 0x01 0xCC

This package or packages like that are needed to be sent to control Dynamixel RX-28 motor.

How can i send a package like given above to UART. How does the definition must be?

P.S. I have a RS485 Breakout connected to UART to feed motor.

I have to drive 12 pieces RX-28 servomotors and i have less time.The UART is enough to read or drive digital servomotors? I search the forum and i found the FIFO and DMA . I dont know how can i use these because i don't know how they work or the FIFO and DMA must be use for my project ???.my project is FPGA based biped robot control and balance algorithm design.I read H48c accelerometer(it gives me x,y,z position and tilt) on FPGA and now i must read the motor position to get balance position on robot.
