Tracking issue for examples and tests (IEC-172)

[igrr]

Some of the components in this repo are missing examples and/or example tests. This issue tracks adding the missing examples.

If the component has an empty test_app and the functionality can be adequately using the example only, remove the test_app when adding the example.

Examples

These components don't have examples at all:

• Add example for ccomp_timer (IEC-197) #403
• Add example for dhara (IEC-198) #405
• Add example for esp_encrypted_img (IEC-200) #406
• Add example for esp_serial_slave_link (IEC-201) #407
• Add example for expat (IEC-202) #408
• Add example for jsmn (IEC-204) #409
• Add example for json_generator (IEC-205)  #410
• Add example for json_parser (IEC-206) #411
• Add example for libpng (IEC-207) #412
• Add example for libsodium (IEC-208) #413
• Add example for nghttp (IEC-209)  #414
• Add example for onewire_bus (IEC-210) #415
• Add example for pcap (IEC-211)  #416
• Add example for pid_ctrl (IEC-212)  #417
• Add example for qrcode (IEC-213) #418
• Add example for quirc (IEC-214) #419
• Add example for zlib (IEC-215) #420

Example tests

These components don't have example tests:

• Add example tests for eigen (IEC-196) #404
• Add example tests for esp_delta_ota (IEC-216) #421
• Add example tests for esp_jpeg (IEC-217) #422
• Add example test for esp_lcd_qemu_rgb (IEC-218)  #423
• Add example tests for iqmath (IEC-220) #425
• Add example tests for led_strip (IEC-221) #427
• Add example tests for network_provisioning (IEC-222) #428
• Add example tests for spi_nand_flash (IEC-223) #430
• Add example tests for supertinycron (IEC-224) #431
• Add example tests for thorvg (IEC-228) #435

If the existing example depends on some specific hardware setup, consider adding a simpler test_app which can be run on generic hardware or mocking hardware dependencies.
