See the README.md file in the upper level 'examples' directory for more information about examples. ULP program written in assembly can be found across `ulp/pulse_cnt.S` and `ulp/wake_up.S` (demonstrating multiple ULP source files). The build system assembles and links this program, converts it into binary format, and embeds it into the .rodata section of the ESP-IDF application. - + At runtime, the main code running on the ESP32 (found in main.c) loads ULP program into the `RTC_SLOW_MEM` memory region using `ulp_load_binary` function. Main code configures the ULP program by setting up values of some variables and then starts it using `ulp_run`. Once the ULP program is started, it runs periodically, with the period set by the main program. The main program enables ULP wakeup source and puts the chip into deep sleep mode. When the ULP program finds an edge in the input signal, it performs debouncing and increments the variable maintaining the total edge count. Once the edge count reaches certain value (set by the main program), ULP triggers wake up from deep sleep. Note that the ULP program keeps running and monitoring the input signal even when the SoC is woken up. diff --git a/examples/system/ulp_riscv/gpio/example_test.py b/examples/system/ulp_riscv/gpio/example_test.py index 860326b60a..cce2c6e01f 100644 --- a/examples/system/ulp_riscv/gpio/example_test.py +++ b/examples/system/ulp_riscv/gpio/example_test.py @@ -8,7 +8,7 @@ import ttfw_idf from tiny_test_fw import DUT -@ttfw_idf.idf_example_test(env_tag='deepsleep_temp_tag', target=['esp32s2', 'esp32s3']) +@ttfw_idf.idf_example_test(env_tag='Example_GENERIC', target=['esp32s2', 'esp32s3']) def test_examples_ulp_riscv(env, extra_data): # type: (tiny_test_fw.Env.Env, None) -> None # pylint: disable=unused-argument dut = env.get_dut('ulp_riscv', 'examples/system/ulp_riscv/gpio') dut.start_app()
