- Temp Sensor DS18B20
- Ethernet Module W5500
- ESP-01(hardware Serial1)
- Mini USB Host Shield (Barcode Scanner)
- LCD 2004 20x4 with IIC/I2C/TWI Serial
- Discharge (MilliAmps and MillOhms)
- Serial configuration.
- Add ESP-01(Software Serial5)?
- Fix mini USB host shield (make auto patch)
Good commands will respond with "ACK" If the command is not supported or incorrectly type a "NAK" will be seen. Please allow some time for the command to go thru. During testing without internet connectivity the response time is very high.
| Command | Description |
|---|---|
| reset | This resets the eeprom settings to default settings. device must be restarted |
| milliamps=1000 | This command sets the value to tell the controller to not recharge is its to low of a mAh. |
| shunt=3.3 | This is used to set the measured shunt resistor resistance. |
| refv=4.95 | This is used to set the referenceVoltage as most devices are not 5v exactly. |
| cutv=2.8 | This is used to set the max dischage voltage. this will stop the battery from discharging to low. |
| timeout=1 | The time in Minutes to rest the battery after charge. 0-59 are valid. |
| millohms=500 | This is used to set the max battery resistance. if its higher it will mark the battery as bad. |
| ohmoffset=0 | Offset calibration for MilliOhms(you should ever need to change this) |
| chrgtimeout=8 | Battery charge timeout in hours. if it take over the allotted time it marks it as bad. |
| tempthreshold=7 | Warning Threshold in degrees above initial Temperature(you shouldn't need to change this) |
| tempmax=10 | Maximum Threshold in degrees above initial Temperature - Considered Faulty(you shouldn't need to change this) |
| server=submit.vortexit.co.nz | Server to connect - Add your server here |
| userhash=j08asd08d | Database Hash - this is unique per user - Get this from Charger / Discharger Menu -> View |
| cduintid=1 | CDUnitID this is the Units ID - this is unique per user - Get this from Charger / Discharger Menu -> View -> Select your Charger / Discharger |
| ssid=yournetwork | Sets your networks ssid(name) |
| pass=yournetwork | pass Set your network password |
| read | This dumps the currently set eeprom values to the serial port. |
