Integration
Global Data
The following global symbols must be defined in CDD_Data.c and .h (populated by PwmCdd):
uint16: CDD_DCPhsComp_Cnt_G_u16[3]
uint16: CDD_PWMPeriod_Cnt_G_u16
Component Conflicts
This component replaces an existing NHET component. The ePWM component contains the NHET program specific to ePWM operation. In addition, the Ap_ePWM2 developer component replaces the Ap_Nhet2 component.
Include Path
The “include” directory of this SWC needs to be included in the integration project include search path.
ADC2 Changes
The ePWM module must be configured to start ADC conversions for the ADC2 module. This is configured by setting the following register values for the ADC2 module:
G0SRC = 3 (EPWM_A1)
G1SRC = 1 (EPWM_B)
This is done in parallel with pin multiplexing changes to route the appropriate SOCA and SOCB signals to the ADC2 module. See FDD 33E for more information.
Configurator Changes
DIO and IOHwAb
If NHET was previously used to generate PWM signals, reassignments are required (as the ePWM outputs will conflict with assigned DIO pins). This is hardware-dependent; refer to the program’s Resource Allocation sheet or schematic. The following pins are used by ePWM and the ePWM-specific NHET on the TMS570LS1227 PGE (144 pin) package (see the datasheet for more information):
| Pin | Function |
|---|---|
| 6 | N2HET1[11], MIBSPI3NCS[4], N2HET2[18], ETPWM1SYNCO |
| 14 | GIOA[5], EXTCLKIN, ETPWM1A |
| 15 | GIOA[6], N2HET2[4], ETPWM1B |
| 22 | GIOA[7], N2HET2[6], ETPWM2A |
| 23 | N2HET1[1], SPI4ENA, N2HET2[8] |
| 24 | N2HET1[3], SPI4NCS[0], N2HET2[10] |
| 25 | N2HET1[0], SPI4CLK, ETPWM2B |
| 30 | N2HET1[2], SPI4SIMO, ETPWM3A |
| 31 | N2HET1[5], SPI4SOMI, N2HET2[12], ETPWM3B |
| 33 | N2HET1[7], N2HET2[14], ETPWM7B |
Port
Pin Direction Settings
The changes in DIO (hardware-dependent) may require updates to the pin direction and other settings for the newly configured DIO signals.
Multiplexing Changes
Several multiplexing options must be configured for both external routing (peripherals to pins) and internal routing (peripherals to peripherals).
The following changes must be made within configurator:
Multiplexing for DIO changes (hardware-dependent)
Multiplexing for NHET component change
This should result in PINMUX1[8-15] being set to 0x04
While N2HET2[8] and [10] can be configured, configurator does not generate these values correctly (see the manual configuration below)
ADC Trigger Table – select ADC Trigger Table 2
This should result in PINMUX30[0-7] being set to 0x02
The following changes must be made with manual edits to Port_PBcfg.c:
| Register | Bits | Value | Selected Option |
|---|---|---|---|
| PINMUX2 | 24-31 | 0x04 | ETPWM1A |
| PINMUX3 | 16-23 | 0x04 | ETPWM1B |
| PINMUX4 | 0-7 | 0x04 | ETPWM2A |
| PINMUX4 | 16-23 | 0x10 | N2HET2[8] (configurator errata) |
| PINMUX4 | 24-31 | 0x10 | N2HET2[10] (configurator errata) |
| PINMUX5 | 0-7 | 0x04 | ETPWM2B |
| PINMUX5 | 8-15 | 0x04 | ETPWM3A |
| PINMUX5 | 16-23 | 0x08 | ETPWM3B |
| PINMUX6 | 0-7 | 0x10 | ETPWM7B |
| PINMUX31* | 16-31 | 0x0202 | ADC2 Trigger Event Selection |
| PINMUX35* | 24-31 | 0x00 | SOC4A_SEL cleared |
| PINMUX37* | 0-31 | 0x01010102 | Sync time bases, enable clocks for ePWM 0 to 3 |
| PINMUX38* | 0-31 | 0x01000001 | Enable clocks for ePWM 4 and 7 |
* Configurator does not define symbols for these registers. Define the following symbols manually:
#define PORT_BASE_ADDR_PINMUX_31 ((Port_RegisterPtrType)(0xFFFFEB8C))
#define PORT_BASE_ADDR_PINMUX_35 ((Port_RegisterPtrType)(0xFFFFEB9C))
#define PORT_BASE_ADDR_PINMUX_37 ((Port_RegisterPtrType)(0xFFFFEBA4))
#define PORT_BASE_ADDR_PINMUX_38 ((Port_RegisterPtrType)(0xFFFFEBA8))
A default value of 0x01 should be used for bytes not otherwise defined.
Runnable Scheduling
This section specifies the required runnable scheduling.
| Runnable | Scheduling Requirements | Trigger |
|---|---|---|
| Nhet_Init1 | Place in EcuStartup_Init1 (EcuStartup.c) along with ePWM_Init1, following the memory initialization routine SchM_InitMemory. | Init |
| ePWM_Init1 | Place in EcuStartup_Init1 (EcuStartup.c) along with Nhet_Init1, following the memory initialization routine SchM_InitMemory. | Init |
| ePWM_Per1 | Must be placed in the motor control ISR, following PwmCdd (or whichever function populates the global variables used by ePWM). | Cyclic (ISR) |
