hi Pippo,

You can read the pad value for a single pin with the emlib API GPIO_PinInGet() after configuring it as input mode.
https://github.com/SiliconLabs/peripheral_examples/blob/public/gpio/switch_led_polled/src/main.c

Regarding to the ADC, the example below is a good starting point.
https://github.com/SiliconLabs/peripheral_examples/blob/public/adc/adc_single_interrupt/src/main_Series1.c

You can get more information about the ADC from AN0021.

Thanks

hi Mkr,

AN0016.1 provided the answer for you questions.

Thanks

hi Hlo,

Did you update to the latest library of both Host side (PC) and device side (C8051F342) simultaneously ?

Thanks

hi Rholman,

In fact, the system reset is not necessary after gecko_evt_le_connect_closed_id unless you need to reset the system to enter DFU mode. You can just use the gecko_cmd_le_gap_start_advertising to restart advertising after client has disconnected.

That should depend on the behavior of the iOS app, you should make sure that the connection not be closed intentionally while closing the app. Monitor the evt_le_connection_closed is a good method to clarify it.

Thanks

hi David,

Thanks for the update, so you can get the Serial Number, Manufacturer and Product strings with the lsusb -v command, however, cannot get it with the HidUartExample ?
My wild guess is that the issue should be caused by the host behavior (libUSB), you can check if the host has sent the get string descriptor command during enumeration with a USB protocol analyzer.

Thanks

hi ArmandR,

Yes, the example below demonstrates how to generate frequency using TIMER. 
https://github.com/SiliconLabs/peripheral_examples/tree/public/timer/frequency_generation
And you do need to capture (count) the number of pulses and stop the frequency generator.

Thanks

hi Frank,

Do you have any chance to check if the example code below can work well on your end ?

Thanks

hi Dh29,

The API of CP2114_ReadOTP() will call HidDevice_GetFeatureReport_Control() (AN532) to get the OTP All Configurations from the CP2114 device to the host over the control endpoint.
I suspect the HID_UART_UNEXPECTED_CACHE_DATA error may has some relation with the incorrect parameter setting of CP2114_ReadOTP(), how about the cp2114Address and ReadLength value in your source code ?

Thanks

hi David,

You should be albe to get the CP21xxCustomizationUtility below after installing the USBXpress SDK, however, I don't think that you can use it for your particular Linux/ARM architecture.
C:\SiliconLabs\MCU\USBXpress_SDK\Customization\CP21xx_Customization\AN721SW_Linux\customizer

In fact, currently, the cp211xsmt only support CP2110, CP2112. I don't think we have a command-line tool for the CP2114 manufacturing. ( We're planning on adding Xpress Configurator support, however, do not have a clear schedule yet).

Beside using the CP21xxCustomizationUtility, another option is to make a little program using SLABHIDtoUART.dll. Use the CP2114_ReadOTP() to read partial or full OTP customization block, and writes partial or full OTP customization block by using CP2114_WriteOTP();

I tried to build the HidUartExample on my linux (ubuntu) PC, it can get the Manufacturer and Product string correctly. And in fact, you also can get the executable binary "hidUartExample" in the locatio below after installing the USBXpressHostSDK-Linux.
C:\SiliconLabs\MCU\USBXpressHostSDK-Linux\USBXpressHostSDK\CP2110_4\Examples\x86_64

The KBA below provided detailed steps for how to build the HidUartExample.

Thanks

hi SHIKHAR,

Do you mind to tell me which board did you use, our STK board or your own board ? And did you configure the Tx/Rx port/pin/location correctly ?

Thanks
