Other Parts Discussed in Thread: CC3100,
Hello everyone ,
I have CC3100 and i am trying to port it to Atmel SAMD21 microcontroller. I have compiled simplelink library and ported required functions on user.h
in main.c i have configureSimpleLinkToDefaultState() function. Basically this function makes my module ready for communication. I have also osciloscope shots on on breakpoint while debugging.
YELLOW - IRQ PIN
BLUE - CS PIN
At the begining CS and IRQ pins are on low- position.
If you go step into sl_Start(0,0,0) command. There is g_pCB->FD = sl_IfOpen((void *)pDevName, 0); command which configures the spi communication and adjusts cs pin high. After sl_IfOpen() command osc. shot is like below.
After spi spi configuration interrupt registiration codeblock comes. after sl_DeviceEnable() command irq pin goes high as you see on osc. shot.
After sl_DeviceEnable(); command there is if(NULL == pInitCallBack) block. If i use CC3100BOOST with MSP430F5529LP it doesnt enter to this if block. But on Samd21 it enters and it waits on this line for a while
retVal = _SlDrvSyncObjWaitTimeout(&g_pCB->ObjPool[ObjIdx].SyncObj, INIT_COMPLETE_TIMEOUT,SL_DRIVER_API_DEVICE_SL_START);
Then _SlDrvRxIrqHandler function gets triggered.
After that my ISR function is triggered.
Then SAMD21 External Interrupt Handler function is tirggered.
An then it goes to my Spi_Write() function , after writing event IRQ pin gets low . CS pin first gets low and goes high again. Remember YELLOW - IRQ / BLUE - CS
At the end it comes to this page and line and it freezes there. Line number : 1140.
I need help. Where am i wrong ?
Thank you .
