SAM E54 Platform » mTracker(Mid Range GW)-Pilot

Hardware for AI and DI will be available on 13/01/2026

Due date extended to 20/01

Device was not ready for testing the ADS115 module. So I couldn't complete the integration testing.

So, Due date need to be extended.

The IO module is being checked with E54EVK and IO PCB module due to the shortage of GW2.0 unit

AI testing completed with the Hardware setup.
Here is the tested report link uploaded in one drive.

@DEVI PRIYAA : Please update the sheet with formula used in the s/w. Also specify the constants
@Dhilip Kumar R : What is the sense resistor value ?

#11 is a deviation as it is a saturated value(32767)

Resistor is 108E (75E+33E)

Required linear range is 0-22mA, with 108E => 0 - 2.37volt

hence 2.048 reference will give saturated ADC value

Two options

1. Adjust sense resistor

2.048/22 = 93E with this, redesign the protection circuit

2. Use 4.096 as reference
   Need to update the s/w

ADC Results used here => https://elpisit-my.sharepoint.com/:x:/g/personal/satish_sl_elpisitsolutions_com/IQCOz9sps2ykRaTcm8Mxw98hAQYrDEYVwgb3juo3Twyp03E?e=AwEhVA

Use this sheet for further testing

After the software updation of 4.096 reference the testing done.

@Dhilip Kumar R : What is "circuit opened" in TR ?

The required linear operating range is 0–22 mA, With a 108E, this corresponds to an output voltage range of 0–2.37 V. For voltages above 2.37 V, the circuit opens to prevent damage.
