Connect RMT TX out to MCPWM FAULT in
Hi, Its possible to connect RMT TX to MCPWM FAULT via gpio matrix? Im trying like this: mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM_FAULT_0, GPIO_NUM_15); rmt_set_pin(RMT_CHANNEL_0l, RMT_MODE_TX, GPIO_NUM_2); gpio_matrix_out(GPIO_NUM_15, SIG_IN_FUNC224_IDX, false, false); gpio_matrix_in(GPIO_NUM_2, SIG_IN_F...

[SOLVED] GPIO logical AND
No, sorry. Yes ;-) Solution: mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM0A, GPIO_PWM0A_OUT); mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM_FAULT_0, INPUT_0); mcpwm_gpio_init(MCPWM_UNIT_0, MCPWM_FAULT_1, INPUT_1); mcpwm_config_t mcpwm_config = { .frequency = 125000, .cmpr_a = 100.0, .counter_mode = MCPWM_UP_DOWN_COUN...

GPIO logical AND
Hi,
Can you realize AND logical for 2 GPIO inputs and 1 GPIO output without interrupts and reading states in the loop?
Is the use of gpio_matrix_in and gpio_matrix_out the right direction?

MCPW OOK modulator
Hi,
I need help configuring the MCPWM driver.
I want to control the H-bridge, OOK modulation, carrier wave - 50 kHz.
The details are shown in the picture.
