The TS-7970 includes 3 channels of ADC that can sample a 4-20mA current loop at about 2/3 samples per second. These are accessed using the tsmicroctl utility:
root@ts-imx6:# tsmicroctl --info VDD_ARM_CAP=1216 VDD_HIGH_CAP=2618 VDD_SOC_CAP=1246 VDD_ARM=1456 SILAB_P10=0x39B SILAB_P11=0x0 SILAB_P12=0x0 VIN=12241 V5_A=5207 V3P1=3276 DDR_1P5V=1571 V1P8=1894 V1P2=1262 RAM_VREF=783 V3P3=3543 SILABREV=1 SILAB_P10_UA=21472 SILAB_P11_UA=0 SILAB_P12_UA=0
The other samples are the various voltages on the board, but SILAB_Pnn and SILAB_Pnn_UA include the raw values from the terminal block ADC, and one output in microamps.
