/**
* this case is used for test PCNT
* prepare job for test environment UT_T1_PCNT:
bugfix(pcnt): fix driver ut pcnt * Let `[ignore] case` return to freedom 1) Because this test uses its own ISR, we need to release it with `esp_intr_free` instead of `pcnt_isr_service_uninstall`. 2) `pcnt_evt_queue` needs to be created before the interrupt is registered and needs to be released at the end of each case. * Add test support for ESP32S2 * Support chip internal connection, no external wiring required.
2019-12-02 03:34:59 -05:00
* We use internal signals instead of external wiring, but please keep the following IO connections, or connect nothing to prevent the signal from being disturbed.

* 1. prepare one ESP-WROOM-32 board and connect it to PC.

* 2. connect GPIO21 with GPIO4
test: components/driver: pcnt case
2018-06-06 07:56:43 -04:00
* 3. GPIO5 connect to 3.3v
* 4. GPIO19 connect to GND
* 5. logic analyzer will help too if possible
*
* the GPIO18 is the pulse producer, the GPIO4 is the input GPIO
