The existing configuration of the ESP32 UART FIFO thresholds was fixed, leading to inefficiencies in handling Modbus RTU packages exceeding this size. This commit introduces two new Kconfig options, allowing users to adjust the esp32 fifo thresholds as needed. fixes #74311 Signed-off-by: Omer Gozderesi <omer.gozderesi@enda.com> config: esp32: configurable UART FIFO thresholds The existing configuration of the ESP32 UART FIFO thresholds was fixed, leading to inefficiencies in handling Modbus RTU packages exceeding this size.

This driver uses the peripheral called USB Serial/JTAG Controller
|
|
(USB_SERIAL_JTAG), which acts as a CDC-ACM interface towards the
|
|
USB host. The USB stack is built into the chip and accessed
|
|
by the firmware through a simplified API similar to a "normal"
|
|
UART peripheral.
