基于 FPGA 开发的功能键盘,将多种按键分类为自锁键(普通编码键盘)和自复位键(较大规模矩阵扫描键盘),通过多次采集键值和无键值获取持续时间的计算实现按键防抖,采用键值返回指示的回显功能确认环路良好,在很大程度上提高了键盘的准确性、稳定性和可靠性.同时还具备设计灵活,便于量身裁剪等特点.

Keys are assorted into non-self-reset push-keys and self-reset push-keys. By analyzing key-values from different data collections and calculating non-key-value lasting time, FPGA can get a accurate key-value without jitter. Key-values that are sent to computer will be encoded and sent back to FPGA, by doing this the keyboard knows if the circuit is all right. This kind of keyboard can be flexibly redesigned.
