Hello TI Team.
I have similar question to this one:
but relating to software.
In the TMDSSOLARUINVKIT SolarMicroInv-Main.c file there is a section for mapping channels to ADC pins.
Here it is:
// EPWM 3 SOC Signals ChSel[0] = 6; // Dummy read for first ChSel[1] = 6; // A6 - IPV, A2 - IP1 Sen - CT ChSel[2] = 11; // B3 - VPV //ChSel[3] = 14; // B6 - VBOOST in Rev 1 PCB ChSel[3] = 4; // A4 - VBOOST in Rev 2 PCB // EPWM 1 SOC Signals ChSel[4] = 1; // A1 - IGRID ChSel[5] = 1; // A1 - IGRID ChSel[6] = 9; // B1 - VGRID ChSel[7] = 7; // A7 - Ref_1.65V ChSel[8] = 5; // A5 - Ref_0.5V ChSel[9] = 8; // B0 - LEM Current Reference Output //ChSel[10] = 0; // A0 - PLC
Two questions:
1. Just to be sure, are numbers that are assigned to the ChSel array represent the ADC pin number?
2. If so, in ChSel[1] = 6 the IPV is used and IP1 Sen is ignored which would suggest that Hall Effect current sensor is used. Am I right?
