Q: should i use battery when i upload the code from arduino ?

Asked by BG208434018 on 2021-03-25 02:58:15

Leon If you are using the USB jack to upload, the host computer will power the board. You won't need the battery, but you don't need to remove it either.

Q: Can you also flash the bootloader with this kit?

Asked by andr00ahayes1967 on 2021-02-08 06:24:45

Leon I was unable to get he included USB adapter to work with my Windows 10 laptop. Instead of pursuing it deeply, I upgraded to the 1.1.5 mainboard. This came with a bootloader and silent stepper drivers.

I've only tried out the display and the buttons so far. I'm using the ESP32 library for Arduino IDE. I use the "ESP32 Dev Module" board selection. The only display library I found that would work is Ucglib (https://github.com/olikraus/ucglib). All others I tried would only drive 3/4 of the display. I've not been able to find any documentation for this board beyond what is shown in the product listing here. From digging through the code for the weather station (https://github.com/LilyGO/Color-Weather-Station-ESP32) I determined that the display controller is probably a ILI9341 using hardware SPI. That's the interface I used with Ucglib to get it to work.

The relay board appears to work well. The only issue is a lack of documentation. After significant search time I have found some things. The board came pre-loaded with a WiFi scan program. After hooking it up to a serial monitor it reported a list of the visible WiFi networks. I was able to program it using the Arduino IDE as a Generic ESP8266 module. Use P6 right next to the power terminals. The pins are labeled TX. RX. & GND. This is a serial port to upload the software. P5 right next to it is the Boot terminal. If these pins are connected together when the board is powered up,it goes into boot mode, ready to receive a software load. I had to update to version 2.6.3 of the ESP8266 package to get reliable programming. The builtin LED is on GPIO 2. The relay control is on GPIO 4. The Optocoupler input is on GPIO 5. The pins for the input are +5v from the on-board buck converter, Optocoupler IN, and Optocoupler ground. The Optocoupler ground is NOT connected to the board ground.

Asked by Leon on 2018-12-20 11:33:01

realblades gpio.mode(2,gpio.OUTPUT); gpio.write(2, 1); gpio.write(2, 0); Worked for me with the stock LuaNode fw that it came with. You don't say what you tried exactly. Maybe you haven't changed the pin mode?

TL:DR BLTouch is fine. Supplied programmer is incompatible with my Win10 PC All required parts were included. The mount for the BLTouch is metal and fits nicely. Pin 27 board is clearly labeled for wiring. Everything seems to be working fine now, but it was tough getting there. The programmer supplied to me with the kit was a USBHID. Apparently, from online research, a US-based Windows 10 PC won't work with this. It requires a USBASP version. Instead of waiting for an exchange, I decided I would add a boot loader using an Arduino UNO as a programmer. That wouldn't work with my Creality 1.1.3 board. (no fault of Bangood), Then I decided now was a good time to upgrade to the silent 1.1.8 board which has a bootloader already installed. Then I couldn't figure out how to flash the BLTouch hex file from Creality onto the new board using the USB port. So I used the Marlin software with BLTouch enabled. So in the end, the only issue that Bangood is responsible for is the unusable USBHID programmer. All my other problems were self-inflicted. I'm happy with the BLTouch. All's well that ends.
