Re: how to change the setting in QORC-sdk to use serial port instead of hardware uart for data capture?

To use the USB-Serial port for data capture change the settings in Fw_global_config.h file in qf_apps/qf_ssi_ai_app/inc folder as below:

Code: Select all

#define DEBUG_UART  (UART_ID_HW)  // Set the output of debug messages
#define UART_ID_APP  (UART_ID_USBSERIAL)       // Set the output for application messages

Re: Sparkfun BME280

Hi @mithundas,

Changes related adding BME280 to the qf_ssi_ai_app look OK to me. It is unclear why the sensor data is 0s.
To help further analyze, trace of I2C transactions between Quickfeather and the BME280 would be helpful.

Re: simple GPIO and SensiML interfacing

Verify that the live-streaming macro is enabled and recognition mode is disabled. /* Settings for the sensor processing modes, Enable only one of these mode */ #define SENSOR_SSSS_RECOG_ENABLED 0 /* Enable SensiML recognition */ #define SENSOR_SSSS_LIVESTREAM_ENABLED 1 /* Enable live-streaming for d...

Re: TinyFPGAProgammer Flash issue on Quickfeather

Hi @moinakg2, Please verify that qf_bootloader.bin file is located in the directory where the command is being invoked. To verify issue the command
$ ls qf_bootloader.bin


Typically bootloader is not required to be programmed. To program an application binary use the --m4app option.

Re: Audio Recognition Mode not displaying result

To use the qf_ssi_ai_app in the audio recognition mode, please update the following macros in the source code: Select audio sensor in the Fw_global_config.h /* Settings for selecting either Audio or an I2C sensor, Enable only one of these mode */ #define SSI_SENSOR_SELECT_AUDIO (1) // 1 => Select Au...

Re: simple GPIO and SensiML interfacing

@Shapy

Reviewed the source_files.zip, please remove the following Line#39 in sensor_ssss.cpp

#include "SparkFun_ADS1015_Arduino_Library.cpp"

The above statement is causing this to be compiled twice.

Re: USBSERIAL Reliability Issues with qf_ssi_ai_app

The below changes would help with using the USB-serial with simple streaming application project: 1. Enable the macro FEATURE_USBSERIAL, set macro DEBUG_UART to UART_ID_USBSERIAL in Fw_global_config.h 2. Use volatile in the for loop to wait for the USB serial to be recognized by Windows (in main.c) ...
