C2000™ 32位实时 MCU 第3页

1，我们在实际开发中遇到了芯片损坏问题：大概现象是：反复上下电十几次后出现ADC采样数据异常的问题，已经排除外围电路影响（在不贴装0049的情况下各AD信号电压都正常，贴装之后出现波动、漂高等现象），据此怀疑可能是供电回路或者上电时序存在问题导致0049芯片损坏；

2，在280049的datasheet中，7.9.1.4.2 Signal Pins Power Sequence章节：  Before powering the device,  no voltage larger than 0.3 V aboveVDDIO or 0.3 V below VSS should be applied to any digital pin… 此处的VDDIO指的是3.3V（假设我设计中的供电电压就是3.3V），还是该描述的上电过程中某一时刻的实际VDDIO电压？   ————-比如在上电过程中的某一时刻，VDDIO 和VDDA 电压才达到1.0V,但某个GPIO和ADC采样输入端口电压是3.3V，会导致7.9.1.4.2 章节中描述的损坏么？

hi，

我们的项目在编译后出现以下warning

#10247-D creating output section "FPUmathTables" without a SECTIONS specification

但是，在工程中没有找到"FPUmathTables"，想问下，如何消除这个warning

另外一个warning，也请帮忙解决

请尽快帮忙解决，

thanks~

请教一个问题，dsp28035 能接收扩展帧，接收不了标准帧？

目前，扩展帧能发送、能接收。

标准帧能发送，不能接收。

您好，我目前在绘制280049的最小控制板，采用的是280049PZS型号。针对ADC的参考电压问题，我看手册上有说可以采用内部参考电压和外部参考电压两种，但是手册中只给出了外部参考电压的电路图，如下图所示。而内部参考电压模式的VREFHIA/B/C如何连接并未给出详细说明。同时，手册上讲说内部参考电压有两种模式，具体是怎么设置也不太清楚。希望能给出相应的解答，非常感谢！

我们为您进行了查询，目前提供的C2000系列的手册里面没有时序图。

您到英文论坛发帖问问产品线有没有这个资源，因为我看MSP430系列芯片是提供了这个时序图的。

不能，之前有过回复。
