IQsqrt 和IQmpy 区别 在CCS5中

$
0
0

在ccs5中,IQsqrt 和IQmpy 区别是啥?为何在ccs3.3中没事呢?

,如果用到_IQ1sqrt函数,如下:iw=_IQ1sqrt(100000*2);

编译后,会提示如下报警:

#16002-D build attribute vendor section TI missing in "../LIB/IQmath.lib<IQ1sqrt.obj>": 

如果用 Vref=_IQ10mpy(2024,1024);,编译后,反而正常,无报警提示。

将原来应用F28335芯片的工程改为F28379芯片,更改了头文件,及一些初始化程序后,在官方给的头文件中报出了错误。请问各位老师,这个问题可能出在什么地方了,怎么修改呢?错误如下图。

[SOS] 28377D FLASH API 使用问题

$
0
0

我在调用Fapi_issueProgrammingCommand() 对地址0x831C6 进行编程时,由于地址是C6开始,所以我的编程字节数是:2个16Bits,但是感觉没能编进去,而且奇怪的是该API 也没有报错;

我知道手册上有说最多只能128bits,且地址要求128bits 对齐,

按理来说按照我这个设置,编程完成后恰好是对齐到128bits的末尾,但为什么Flash 并没有被刷写呢?

//! \addtogroup example_list
//!  <h1>Watchdog Interrupt</h1>
//!
//!  This program exercises the watchdog.
//!
//!  First the watchdog is connected to the WAKEINT interrupt of the
//!  PIE block.  The code is then put into an infinite loop.
//!
//!  The user can select to feed the watchdog key register or not
//!  by commenting one line of code in the infinite loop.
//!
//!  If the watchdog key register is fed by the WDOG_clearCounter function
//!  then the WAKEINT interrupt is not taken.  If the key register
//!  is not fed by the  WDOG_clearCounter function then WAKEINT will be taken.
//!
//!  Watch Variables:
//!  - LoopCount for the number of times through the infinite loop
//!  - WakeCount for the number of times through WAKEINT

XDS110仿真器连接不上,提示锁死,如何解锁

一直用XDS110给TMS320F2806核心板烧写程序,因其他原因导致核心板连续掉电多次后,出现XDS110烧不进程序的问题。错误提示如下:

Error connecting to the target:
(Error -1015 @ 0x0)
Device is not responding to the request.  Device may be locked, or the debug probe connection may be unreliable. Unlock the device if possible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 8.0.903.4)

提示好像XDS110烧录器被锁死了,请问怎么解锁呢。

另外,换别人在用的XDS110可以正常烧写,可以排除程序和ccs8.1配置的问题。

我想问一下关于占空比计算这一块儿,是如何理解的,为什么要加v.HalfPerMax?还有就是CMPA的值小于0或者超出TBPRD什么操作?

(*ePWM[ch1]).CMPA.half.CMPA = _IQmpy(v.HalfPerMax,v.MfuncC1)+ v.HalfPerMax; \
(*ePWM[ch2]).CMPA.half.CMPA = _IQmpy(v.HalfPerMax,v.MfuncC2)+ v.HalfPerMax; \
(*ePWM[ch3]).CMPA.half.CMPA = _IQmpy(v.HalfPerMax,v.MfuncC3)+ v.HalfPerMax; \

基完成了把gpio 切到cpu2的先关设置,但是不知道还有没有别的先关设置,请指点。

在cpu1里设置如下, setup_emif1_pinmux_async_16bit(GPIO_MUX_CPU2);  //将数据地址总线io 切到cpu2,别的不知道还要设置什么?
