- 在Altera公司的Cyclone系列FPGA开发板上试验的按键中断程序,希望对那些学习中断开发的初学者有帮助。 pio_key.v是verilog编写的按键中断程序,对应四个按键,按其中任何一个键都可以发送一个中断; keyint.c是Nios中编写的C程序,用于检测按键的中断,如果检测到中断,会检测是哪个按键按下,从而执行相应的程序! -In Altera' s Cyclone series FPGA development board interrupt key test
key
- Verilog HDL编写的键盘扫描程序,考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线,同时检测列线的状态,一旦判断有一列为低则表示有键被按下,停止扫描并保持当前行线的状态,再读取列线的状态从而得到当前按键的键码;等待按键弹起:检测到各列线都变成高点平后,重新开始扫描过程,等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. P
