[讨论] DIY电源dontium小组，招募C2000编程工程师......

此为dontium小组DIY进展：https://bbs.eeworld.com.cn/thread-311388-1-1.html

希望有TI F28035编程经验、有一定时间和精力、并乐于分享的朋友加入！

如果有兴趣，可以跟帖说明，并通过站内短消息给soso，告知QQ号码。

期待DIY电源开源设计小组，有你的加入。

支持一下，赶快做出成品，很多人等着呢！~

恩，排队等

顶顶，没接触过dsp

围观！！

毕业设计时用过2810
没有什么经验

F28035是用C28系列CPU，2810也是，编程是一样的

顶，围观

有2810、2812经验也是可以的
只是俺没有太多充裕的时间

DIY电源 需要大家的共同参与、贡献， 单凭几个人的力量毕竟是有限的

 

力量不在多少，只要尽力就好

其实我是很想参加啦；不过怕耽误大家的进度。
要不我贴一下我毕业设计的代码吧；要是大家觉得还可以的话，那希望能出一份力
这是我2011年毕业那时写的，主要功能就是控制两个电机移动到指定的位置；通过AD采样获取移动的位置

下面是那时写的main文件，其他详见附件 （ccs3.3的）

// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the DSP281x_SysCtrl.c file.

// For this example, set HSPCLK to SYSCLKOUT / 6 (25Mhz assuming 150Mhz SYSCLKOUT)

// This example function is found in the DSP281x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.

// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts

// Initialize PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.

// Service Routines (ISR).

// is not used in this example. This is useful for debug purposes.

高手应该是有，只是高手一般都很忙。这是个矛盾。
