Hello,
I’m getting acquainted with the OpenLog Artemis and the Qwiic ADS1015 A/D. I selected the ADS1015 in order to make use of the 16X gain while I measure current flow through a milliOhm shunt resistor (similar to the application note in the ADS101x data sheet). The intention is to construct a handheld portable logger that isn’t tethered to a PC for re-configuring the logging in the OLA every time I start a new log file. I’d like to avoid the complication of hauling a laptop to the equipment that I want to investigate.
But I’m running into difficulty. At any restart of the OLA, the A/D module goes back to it’s default of the 1X gain setting. I’d really like it to stay at 16X, or alternatively, have the OLA set the A/D to 16X at startup. I’d also like to maintain a differential measurement, but those all get disabled in a restart.
Is there any recipe of settings in the OLA to make the configuration durable? Maybe something subtle with the power control that keeps a “session” live while I run multiple logs?
Or failing that, has anyone thought that they might implement a new feature of adding a User Preset function that can be employed at startup?
Or failing that, is there a plan to develop communication to the OLA via an iOS or Android device?
Thanks,
