ESP32-C3-PICO-A for nodeMCU problem

[vmarks]

Hi,

I have a ESP32-C3-PICO-A that doesn't use USB for serial, so I use a FTDI for serial. I have it loading the ESP32 C3 with this code

Connecting... Detecting chip type... ESP32-C3 Chip is ESP32-C3 (QFN32) (revision v0.4) Features: WiFi, BLE Crystal is 40MHz MAC: ec:da:3b:b7:01:78 Stub is already running. No upload is necessary.

is what I have.

What is needed to send the ESP32 C3? I was trying to use esp tool in terminal.

If you are trying to flash to prebuilt image to the C3 it will not work - the image is built for the ESP32 only.

You will need to compile and upload your built image, and im unsure if the code will work correctly on the C3 (its never been tested)

Hi!

The ESP32 image should be working with the ESP32 I used - the one I used is the ESP32 - C3-Pico-A for its specific ESP32, but it's the same ESP32 used in it. The M5 Atom Lite is the ESP32 has an IR led, a switch, but have the same RAM and rs232 serial.

While I work at the code, can I ask a different we have asking... which ESP32 is the part that is used for this code? https://shop.m5stack.com/products/atom-lite-esp32-development-kit?srsltid=AfmBOopJptDZlE3sMYjrhcykoYtDj8Cna70wTHCDZyCdpceHfs205umq&variant=32259605200986 is the M5 atom lite - what are other ones that might be used?

[unreality]

The ESP32-C3 uses a RISC-V CPU, and the ESP32 uses an Xtensa - the prebuilt image is compiled for Xtensa and so it will not work on the C3.

Any ESP32 based module should work (ie the original ESP32, and not any variant such as C3, S2, S3, H2, P4, C6, etc) - but the image is built specifically for the M5AtomLite and the Pins available on that module.

ESP32 variants might work if you compile and upload the image yourself, but they have not been tested and probably require some tweaking for what pins to use.

Hello,

I have get the Xtensa ESP32. I have a problem using the NodeMCU pyflasher. Is there a way to use esptool.py to flash the Atom Lite esp32?

EDIT: here's what I have done so far:

python3 -m esptool -b 115200 --before=default_reset --after=hard_reset write_flash -fs 2MB -fm dio 0x0 ~/Downloads/lgtv-hk.bin

which is a way to saying how slow (115200) the kbps is, when it can write the file, and where for it (0x0). I am checking to see if it does it...

1. This edit allows me to enter Wi-Fi.
2. it does not allow Wi-Fi working (that I know of yet)
3. how do fix this?

[vmarks]

1. Wi-Fi can be connected. Do not use the numeral list for SSID, tell the SSID word for the network. Then, ask the password for Wi-Fi. (SSID name, separate prompt, SSID password)

2. The device will not use a number first. You have to use S 11122333 (or other code) and it will add code first. It will then work with Apple Home to pair it.

My device appears to be on Wi-Fi and Home code, and now needs RS232 for the TV device.

[vmarks]

To set up the RS232C plug, you need to look at it like this:

1 is up left, 5 up right
6 bottom left, 9 down right

pins for the cable are:

RX is 2 pin
TX is 3 pin
GND is 5 pin

[vmarks]

OLED65B7P is the LG that uses a 1/8" cord instead of using a DB9 port. For this, the port is a RS232C service port.

The tip is TX or RX
the middle bit is RX or TX
the rear is GND.

I am working on this problem.
