I saw that new implementation connects gpio to gpio out signal when set direction.
I think one pad can be connected to only one signal. Then the serial signal are disconnected.

static esp_err_t gpio_output_enable(gpio_num_t gpio_num)
{
GPIO_CHECK(GPIO_IS_VALID_OUTPUT_GPIO(gpio_num), "GPIO output ...

Did you found a way to use od in uart tx?

In esp-idf 4.4 it works using: But not in 5.2.

I do not think so. I activated all interrupts and set multiple values for this property, but I could not find what it would be.

UART_BRK_DET_INT: Triggered when the receiver detects at 0 level after the STOP bit.
UART_TX_BRK_IDLE_DONE_INT: Triggered when the transmitter's idle state has been kept ...

Hi,

there is a configuration "UART_RX_IDLE_THRHD" on UART, but I don't found any use for it.
Can someone explain the use of "UART_RX_IDLE_THRHD"?

From Reference Manual (p.361):
UART_RX_IDLE_THRHD When the receiver takes more time to receive Byte data than what this
register indicates, it will ...

For APB_CLK as source for UART, it's 10 baud cycles, i.e., 100 bits (without parity).
But I don't know what is the default source clock. I think it's APB_CLK.

From Reference Manual:
UART_RX_TOUT_THRHD This register is used to configure the UART receiver’s timeout value when receiving a byte. When ...

Hi,

I want to implement J1708 with ESP32. J1708 is a modified version of RS485.
I am using RS485 UART with modified tranceiver and everything is going well for sending and receiving data.
But the J1708 has a standard of time to distinguish messages. It's simple:
After a message, consisting of a ...
