Hi esp_programmer, Sorry for causing confusion by my silly typo :o I'm still a little confused by this. The TRM actually states the EOF bit is set by hardware. I interpreted this to mean a peripheral (e.g. SPI) somehow signals the DMA controller when the bit needs to be written in the descriptor. Ye...

Hi there, Your basic understanding about receive descriptors is correct. The EOF bit in receive descriptors depends on the data to be received: If there is a EOF flag in the data to be received, the EOF bit in receive descriptors will be automatically written to 1 by software. Users can not directly...

Hi there,

These parameters will be released in ESP32-C6 Datasheet v1.0 (the official release for the mass produced chip) hopefully at the end of this month.

For your reference, attached are some preliminary results:

Please note that these data might be different in the official release. Thank you!

Sorry for the late reply and thanks for asking! RTC should not be reset when the chip is woken up by a GPIO from deep-sleep mode. This happens because there is a bug in ESP-IDF code. The bugfix has already merged to the master branch, and is to be backported to other release branches soon. You may p...

Sorry that my previous explanation is wrong. The length of stop bits can be 1, 1.5 or 2, configured by UART_STOP_BIT_NUM. 0: Invalid. No effect 1: 1 bits 2: 1.5 bits 3: 2 bits In RS485 mode, you may add a turnaround delay of a bit before the start bit or after the stop bit, configured by UART_DL0_EN...

Sorry that I just noticed your reply!
It seems that there is some inconsistency between hardware and software. I'm checking and will keep you updated.

Hi there, I'm sorry for the trouble caused by the unclear register descriptions. UART_STOP_BIT_NUM, which is used to set the length of stop bits, has 4 valid values. 0: 1 bits; 1: 2 bits; 2: 1.5 bits; 3: 3 bits. UART_DL1_EN and UART_DL0_EN are used to set the turnaround delay as required by the RS48...

Hi everybody, We have released ESP32-C6 Datasheet and Technical Reference Manual for reference: EN: Datasheet - Specifications of the ESP32-C6 hardware https://www.espressif.com/sites/default/files/documentation/esp32-c6_datasheet_en.pdf Technical Reference Manual - DetailedinformationonhowtousetheE...

Hi there, Your assumptions are correct. The difference between ESP32-C3FH4AZ and other variants is that SPI pins for flash connection are not bonded, so this chip variant has 6 fewer GPIOs available. These SPI pins are internally connected to a 4 MB flash in the chip package. Such information is cov...
