  Fatal error while uploading sketch to A16
Posted by: tanoshimi - 03-20-2023, 03:12 PM - Forum: KC868-A16 - Replies (6)

Hi,  I recently bought a KC868-A16 board but am unable to use it, since I receive a fatal error when attempting to upload any new sketches onto it Sad

I'm using the Arduino IDE v2.0.4, targetting the "NodeMCU-32s" board from the esp32 boards definitions (v2.0.7). This is the error I receive when attempting to upload any sketch:

Code:
Sketch uses 292297 bytes (22%) of program storage space. Maximum is 1310720 bytes.
Global variables use 25300 bytes (7%) of dynamic memory, leaving 302380 bytes for local variables. Maximum is 327680 bytes.

A fatal error occurred: Serial data stream stopped: Possible serial noise or corruption.
Failed uploading: uploading error: exit status 2


There is not other hardware connected to the board. I am using the power supply and USB-C cable that it was supplied with (although I have also tried swapping these for other ones, and also tried different USB ports on my laptop).
As suggested elsewhere, I have tried reducing the upload speed from the default 921600 to 115200, but that made no difference.
The board itself seemed well-packed and doesn't show any obvious signs of damage, but I'm wondering if the chip is faulty, since the error appears to suggest a problem with the flash memory?

Hopefully you can advise! Thanks,

Alastair

  KC868-A256 ESP32 GPIO Module Released!
Posted by: admin - 03-19-2023, 10:53 AM - Forum: News - No Replies

we have design this ESP32 GPIO board (KC868-A256) for home assistant. It use by ESP32-WROOM-32E, 256CH digial input ports + 256CH MOSFET output ports + 4CH analog input ports + RS485 + Ethernet. The output design by 74HC595 chip. The input design by 74HC165 chip. You can write your own arduino source code for home automation DIY. You can also integrate to home assistant by ESPHome.

  KCS Question.
Posted by: Philadam - 03-17-2023, 04:12 AM - Forum: "KCS" v2 firmware system - Replies (7)

Two questions:

1) Is it possible to have an ADC sensor trigger an Input on an A16 with KCS?
2) Will a KC868-HA work with the A16 over RS485?
