Allocation of the temporary internal buffer will now repeat until a small enough buffer can be allocated, and only fail if less than a 256 byte block of internal RAM is free. Adds unit test for the same, and generic test utility for creating memory pressure.

|
|

|
|
* As all DUTs are independent, need user (or test script) interaction to make test synchronized.
|
|
*
|
|
* Here we provide signal functions for this.
|
|
* For example, we're testing GPIO, DUT1 has one pin connect to with DUT2.
|
|
* DUT2 will output high level and then DUT1 will read input.
|
|
* DUT1 should call `unity_wait_for_signal("output high level");` before it reads input.
|
|
* DUT2 should call `unity_send_signal("output high level");` after it finished setting output high level.
|
|
* According to the console logs:
|
|
*
|
|
* DUT1 console:
|
|
*
|
|
* ```
|
|
* Waiting for signal: [output high level]!

|
|
*

* ```

* Send signal: [output high level]!
|
|
* ```
|
|
*
|
|
* Then we press Enter key on DUT1's console, DUT1 starts to read input and then test success.
|
|
*
|
|
* Another example, we have 2 DUTs in multiple devices test, and DUT1 need to get DUT2's mac address to perform BT connection.
|
|
* DUT1 should call `unity_wait_for_signal_param("dut2 mac address", mac, 19);` to wait for DUT2's mac address.
|
|
* DUT2 should call `unity_send_signal_param("dut2 mac address", "10:20:30:40:50:60");` to send to DUT1 its mac address.
|
|
* According to the console logs:
|
|
*
|
|
* DUT1 console:
|
|
*
|
|
* ```
|
|
* Waiting for signal: [dut2 mac address]!
|
|
* Please input parameter value from any board send this signal and press "Enter" key.
|
|
* ```
|
|
*
|
|
