How to define the gpio pin on platform of BCM94343WWCD1?

chwa_1570756 Jun 16, 2018 1:38 AM

Hello,

I have a board of BCM94343WWCD1 and want to test the button and LED example in snip.gpio app, I try to create target and double click it : snip.gpio-BCM94343WWCD1 download run , the code can be found download to the target board but the LED not light when I push button.

I open the gpio.c file and put mouse arrow on the character of 'WICED_LED1', it pop up a hint of : Symbol 'WICED_GPIO_15' could not be resolved, then I open the /platforms/BCM94343WWCD1/platform.h file and fine a line: #define WICED_LED1 ( WICED_GPIO_11 ), which gpio definition is right following the schematics.

So, I wonder why and where 'WICED_LED1' has been defined as 'WICED_GPIO_15', and why the right definition of 'WICED_GPIO_11' was not available even I try to

add #include "platform.h" in the gpio.c file, any obvious step I missed ?

Chris

Hello Chris,

Could you please share which WICED Studio version are you using? I checked with WICED Studio 6.2 on the same platform and it worked just fine. If you want to check the WICED_LED1 GPIO assignment, you can check the same in the platform folder (43xxx_Wi-Fi/platforms/CYW94343WWCD1_EVB/platform.h).

Hello rroy,

Thanks for your reply.
I keep using WICED Studio version 4.4.2 as the local FAE told me the newer version can not support the platform board of BCM94343WWCD1, I also can not find CYW94343WWCD1_EVB platform listed in the older WICED Studio version.
So, are you sure the 6.2 version could support the board of BCM94343WWCD1?

Hello Chris,

For older WICED Studio, the platform name is BCM94343WWCD1, which is updated to CYW94343WWCD1_EVB from WICED Studio 6.2. BTW, could you please provide the console log that you are seeing?

Hi rroy,

I tried to update WICED to version 6.2 and find \platform\CYW94343WWCD1_EVB under new WICED version, but those pin assignments were still not right in the gpio.c file, eg. in the line of wiced_gpio_output_high( WICED_LED1 ); 'WICED_LED1 ' was hinted as 'WICED_GPIO_15' , actully it should be 'WICED_GPIO_11' defined by platform.h of CYW94343WWCD1_EVB.

the listed below is console display:

When you right click and open the declaration for WICED_LED1, it should be correctly mapped to WICED_GPIO_11 in the platform.h file. Are you seeing the LEDs to be flashing now? If not, what is the debug terminal log you are seeing?

Hi RaktimR_11

When I right click and open the declaration for WICED_LED1,it says :"Selected text cannot be mapped to a symbol name",
and those wrong declarations have a red line under the text.

Hello Chris,

I hope now you are able to see the LEDs blinking. The wrong suggestion is an Eclipse specific issue but intenrally it correctly gets mapped to the particular platform.h in the platform directory which you can verify by clicking on the Open Declaration option.

Hi rroy,

I try to update WICED to version6.2 and select CYW94343WWCD1_EVB platform, then it can work properly.
Thanks a lot.

Chris
