如何通过GPIFII读取一个16位数据字并发送？

你好，埃文，
在线程主循环中调用CYU3PGPIFSMwitter（）API，这将导致GPIF状态机在每次迭代时从RDYSTART状态重新启动。在这种情况下，执行STATE4的次数是随机的，不能确定。因此，正在执行的InDATA动作的数量也不是确定性的。
此外，在CPU中断回调函数中，没有调用CYU3PGPFIFECTSWIN（）API，这意味着FWYTRG根本没有发生。
-仅在故障时修改状态机来实现切换到RDYSTATE。
-转变方程从state6到state1为fw_trg和CPU一样执行固件中断回调函数。
CYU3PGPIF控制输入（Cyress）；
CYU3PGPIFIN控制输入（CyFLUE）；
-过渡方程状态1变rd_state作为逻辑。
最好的问候，
斯里纳斯



以下为原文
Hello Evgen,

- The CyU3PGpifSMSwitch() API is called in the thread main loop which will cause the GPIF state machine to restart from RD_START state upon every iteration. In this case, the number of times the STATE4 gets executed would be random and cannot be determined. So, the number of IN_DATA action that is being performed is also not deterministic.
- Also, in the CPU interrupt callback function, the CyU3PGpifControlSWInput() API is not called which means that the FW_TRG is not happening at all.

- Modify the state machine to implement the switch to RD_STATE only upon a failure.
- Change the transition equation from STATE6 to STATE1 as FW_TRG and implement the same in the CPU interrupt callback function in the firmware.
CyU3PGpifControlSWInput(CyTrue);
CyU3PGpifControlSWInput(CyFalse);
- Change the transition equation from STATE1 to RD_STATE as LOGIC ONE.

你好，斯里纳斯！
不使用FWYTRG，它不需要转换，也不需要CYU3PGPIFIN控制输入。
我的主要循环包括许多命令。在CYU3PGPIFSM开关前后设置断路器。然后尝试使用控制中心接收数据。
因此CYU3PGPIFSM开关仅限一次。

Hello Srinath!


FW_TRG not used - it blocks transition and CyU3PGpifControlSWInput is not needed.


My main loop for (;;) consists of many commands. I set breakpionts before and after CyU3PGpifSMSwitch. Then I try to receive data using Control Center.


So CyU3PGpifSMSwitch is calld only once.

我使用CyfxSRAM例子并修改。

P.S I use CYFXSRAMexample and modify.

你好，埃文，
因为你说过，你是设置断点，我明白你正在使用JTAG调试和编程。如果我错了请纠正我。
-请分享UART的日志中收集。调试CPU打印中断回调收集的日志前，包括。
另外，包括GPIF状态机在调试输出。
最好的问候，
斯里纳斯



以下为原文
Hello Evgen,

- Since you have mentioned that you are setting breakpoints, I understand that you are using JTAG debugging and programming. Please correct me if I am wrong.
- Please share the UART logs that is collected during the process. Include debug prints in the CPU interrupt callback before collecting the logs.
Also, include the GPIF state machine number in the debug prints.

Best regards,
Srinath S

我有2个断点。在工作循环中调用CUU3PGPIFSwitt（）函数之前的第一个断点。第二个断点是在Cyu3PDMACHANEL SETRAWAPUP（）函数之前的中断CPU回调中设置的。

你好，埃文，
-亲切地，共享UART日志，可以使用像TeraTerm这样的终端仿真器来收集，因为它可以更容易调试。
此外，使用CYU3PGPIFGETSMSTATE（）API获取GPIF的当前状态，并在UART上打印GPIF。
最好的问候，
斯里纳斯



以下为原文
Hello Evgen,

- Kindly, share the UART logs that can be collected using a Terminal Emulator like TeraTerm as it can be easier to debug.
- Also, use the CyU3PGpifGetSMState() API to obtain the current state of the GPIF and print the same over the UART.

你好，斯里纳斯！
我已经修改了CB功能：
空GpifStopReadDataCb（CUU3PGPIFEvType事件，UIT88T当前状态）
{
Cyu3PrimtStutsUsIt APIRTYSTATION；
Unt8St SMOSTATE；
CYU3PGPIFGETSMSTATE（和SMStand）；
CYU3pDebug打印（CyfxxDebug）优先级，“SM状态= %DN”，SMOSTATE；
If（事件＝CYU3PY-GPIFIAEVTSM中断）{
ApReStisty= CYU3PDMACHANNEL SETRAWAPUP（＆GLCHANDANSELAMPUTHY48）；
}
}
我还有下一个UART日志：



以下为原文
Hello Srinath!

I have modyfied cb function:

void GpifStopReadDataCb(CyU3PGpifEventType event, uint8_t currentState)
{
CyU3PReturnStatus_t apiRetStatus;
uint8_t smstate;
CyU3PGpifGetSMState(&smstate);
CyU3PDebugPrint (CY_FX_DEBUG_PRIORITY, "SM State = %dn", smstate);

if(event==CYU3P_GPIF_EVT_SM_INTERRUPT){
apiRetStatus = CyU3PDmaChannelSetWrapUp(&glChHandleSRamPtoU_48);
}
}
And I have got next UART log:
