1-wire search algorithm

[rjvyas]

hasn't this algorithm already been implemented in: https://github.com/rLoopTeam/eng-software-pod/blob/4d73dee1bc152cf2613a29a874ecb7222a712170/FIRMWARE/COMMON_CODE/MULTICORE/LCCM641__MULTICORE__DS2482S/SEARCH/ds2482s__search.c

@rjvyas you are correct, but our implementation Lint16 s16DS2482S_SEARCH__Search(Luint8 u8DeviceIndex) appears to be incomplete (some empty else statements) and is noted as violating MISRA 2004 (regulations on using C in critical systems) for its use of ~ and <<. I'll check it out!

LG: Empty else statements are not in violation, not having them is a violation.

The following stub exists in ds18b20.c:

//precondition that the DS2482 is operational

    u8ChannelIndex = 0U;
    u8DSIndex = 0U;

    s16Return = s16DS2482S_SEARCH__SearchFirstDevice(u8ChannelIndex, &sDS18B20.sDevice[u8DSIndex].u8SerialNumber[0]);
    if(s16Return >= 0)
    {
        sDS18B20.sDevice[u8DSIndex].u8ChannelIndex = 0U;

        s16Return = s16DS18B20_TEMP__Get_Resolution(u8DSIndex, &sDS18B20.sDevice[u8DSIndex].u8Resolution);

        s16Return = s16DS18B20_TEMP__Request(u8DSIndex, 1U);

        //success
        s16Return = s16DS18B20_SCRATCH__Read(u8DSIndex, &u8Temp[0]);
        if(s16Return >= 0)
        {

        }
        else
        {
            //fall on
        }

    }
    else
    {

    }

Am I implementing something similar to this (from ds2482s__search.c:

if(s16Return > 0)
        {
            //order the address
            pu8Addx[0] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[0];
            pu8Addx[1] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[1];
            pu8Addx[2] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[2];
            pu8Addx[3] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[3];
            pu8Addx[4] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[4];
            pu8Addx[5] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[5];
            pu8Addx[6] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[6];
            pu8Addx[7] = sDS2482S.sSearch[u8DeviceIndex].u8ROM_SerialNumber[7];

        }```

Lets delay this task. The purpose of it was to search all the busses on our power nodes and the temp sensors. Currently the DS18B20 and DS2482 already support searching for 1-wire devices, but not an entire pod level search of all systems.

[rjvyas]

@SafetyLok does this mean that we would also have to delay my task for issue #39 since it also relates to bus search? I think my task is quite dependent on this task even though it is in a different milestone.

[SafetyLok]

Done.
