Hi all,
Does anyone know which HW Modules in AURIX™ are capable to generate PWM?
#8042000 19454
Kind regards
Bernie

Hi Bernie,
Both General Timer module (GTM) and Compare Capture Unit 6 (CCU6x) are able to generate PWM.
Basically, TOM and ATOM in GTM are commonly used to generate PWM.
ATOM and TOM have the most independent timers and channels to generate PWM in 24 bits resolutions (ATOM) or 16 bit resolutions (TOM).
Every CCU6x module has two independent timers with 7 channels for PWM generation in 16 bits resolutions.
Kind regards
Mr AURIX™

Hello Bernie,
In regard to this, you can also find code examples of how to generate PWM signals with both the GTM and CCU6 peripherals here: CCU6_PWM_Generation_1 | GTM_ATOM_PWM_1 together with their tutorials CCU6_PWM_Generation_1 tutorial | GTM_ATOM_PWM_1 tutorial
hope it helps,

Hello, for generating 6 PWMs for 3 Phase Motor control, the only solution is to use CCU6 modules?
How to integrate in this case the driver in AUTOSAR?

Hi bbogdanmircea. It's true that the CCU6 was designed for 3 phase motor control, but the peripheral is basically a legacy from previous 16-bit Infineon microcontrollers. In the AURIX generation, most customers use the GTM for motor control, which offers much more flexibility, and has its own MCAL GTM driver.

Hi Mr AURIX,
How to generate 8 PWMs by GTM TOM? I have referred to GTM_TOM_PWM_1_KIT_TC277_TFT sample code, but it is only one PWM, I tried to revise it for two PWM channels unsuccessfully.

Please share a little code, and we can help figure out where things went wrong.
