Introduction ----------------- - -This software is used to check the reliability of the link between the host -platform (on which the program is run) and the Lora concentrator register file -that is the interface through which all interaction with the Lora concentrator -happens. - -2. Dependencies ----------------- - -This program only access the Lora gateway HAL library through its loragw_reg -"named registers" access sub-module. - -It was tested with v1.0.0 of the libloragw library, and should be compatible -with any later version of the library and the hardware, assuming the registers -used for the tests are still present. - -The registers used are: - * LGW_VERSION - * LGW_IMPLICIT_PAYLOAD_LENGHT - * LGW_FSK_REF_PATTERN_LSB - * LGW_RX_DATA_BUF_ADDR - * LGW_RX_DATA_BUF_DATA - -A data buffer accessible through the 2 registers above must be implemented. - -3. Usage ---------- - -The tests run forever or until an error is detected. -Press Ctrl+C to stop the application. - -When an error is detected, diagnosis information are displayed. Please refer to -the source code for more details on what is displayed for diagnosis. - -All tests use pseudo-random data generated by the rand() function. The random -generator is not seeded, and the same sequence of data will be use each time the -program is launched. - -Basically, some random data is written, read back and then compared to the -initial written data. Some "useless" read on others registers might be inserted -to be sure that the data read back is coming from the hardware, and not from the -internal buffer(s) of the software driver(s). - -Test 1 > R/W on a simple 8-bit register - -Test 2 > R/W on a simple 8-bit register with interstitial reads on VERSION - -Test 3 > R/W on a 32-bit register (short SPI bursts access) - -Test 4 > data buffer R/W (long SPI bursts access) - -4.
