- 你好，我是个niosii 初学者，想实现一个数码管的动态显示，但是软件C程序不知该如何写，能指点一下吗？对了，我用的是DE2的板子，十分感谢！

- So perfect! I do admire you. And recently I do a
project with WinAvr, so could you just make
much more basic information about WinAvr?
Thank you very much2007-11-18 17:05:41
真的很惭愧，搞了两年mcu,fpga，现在的实习工作却跟这一点不相关。spi我们电子设计的时候一直在用，winavr也是（搞avr就应该用这），只是我电脑还在学校，我也没时间回去了......

- 我在用JTAG方式下载时遇到以下问题
Error:CONF_DONE pin failed to go high in
device 1
请问应如何解决?谢谢!2007-08-13 14:16:11
我没有碰到过这种情况，仔细检查一下管脚的连接，电平是否兼容吧！！2007-08-13 14:22:16
You may receive this error from the Quartus® II software if the nCE pin of the device is not connected to GND. For example, if you have a multi-device passive serial chain, the nCE of the first device would be connected to GND, while its nCEO pin would feed the nCE pin of the next device in the chain. Since the second device\'s nCE pin is not connected to GND, JTAG programming would fail and the Quartus II software will report \'CONF_DONE failed to go high in device 2\'. For successful JTAG programming of a device chain, all nCE pins must be connected to GND.
altera官网上的 看看是否有用，，
