Other Parts Discussed in Thread: TMS320F28035, TMS320F280039C, SYSCONFIG, CONTROLSUITE
Again, I'm in the process of migrating a project from the TMS320F28035 MCU to the newer TMS320F280039C MCU. Previously, I utilized a project template which included an "ADC_SOC_Cnf.c" source file for ADC configuration. With the transition to the new MCU, I understand that SysConfig can be used to convert and adapt such source files for compatibility with the TMS320F280039C, taking advantage of the new GUI and the sysconfig directory structure. However, I find the instructions for this conversion process unclear, especially in terms of integrating existing source code with SysConfig-generated configurations. Could anyone provide a step-by-step guide on how to convert existing source files like "ADC_SOC_Cnf.c" for use with the TMS320F280039C through SysConfig? Any tips on navigating the new GUI for this purpose would also be greatly appreciated.
Just for context, the "ADC_SOC_Cnf.c" source file can be found in the template which is located in this directory: C:\ti\controlSUITE\development_kits\TemplateProjects\DPLibv3_4Template-F2803x
This question is related to this question that I have asked previously here .
Below here attached is the source code for that said file.
//----------------------------------------------------------------------------------
// FILE: ADC_SOC_CNF.c.c
//
// Description: ADC configuration to support up to 16 conversions on
// Start of Conversion(SOC) based ADCs (type 3) found on F2802x and
// F3803x devices. Independent selection of Channel, Trigger and
// acquisition window using ChSel[],TrigSel[] and ACQPS[].
//
// Dependencies: Assumes the {DeviceName}-usDelay.asm is inlcuded in the project
// Version: 3.0
//
// Target: TMS320F2802x(PiccoloA),
// TMS320F2803x(PiccoloB),
//
// The function call is:
//
// void ADC_SOC_CNF(int ChSel[], int Trigsel[], int ACQPS[], int IntChSel, int mode)
//
// Function arguments defined as:
//-------------------------------
// ChSel[] = Channel selection made via a channel # array passed as an argument
// TrigSel[]= Source for triggering conversion of a channel,
// selection made via a trigger # array passed as argument
// ACQPS[] = AcqWidth is the S/H aperture in #ADCCLKS,# array passed as argument
// IntChSel = Channel number that would trigger an ADC Interrupt 1 on completion(EOC)
// if no channel triggers ADC interrupt pass value > 15
// Mode = Operating mode: 0 = Start / Stop mode, needs trigger event
// 1 = Continuous mode, no trigger needed
// 2 = CLA Mode, start stop mode with auto clr INT Flag
