I got one of the above - I cannot locate the correct board manager reference to this one, have I bought a pup?
Could you please elaborate on the problem you are facing?
Are you not able to find your specific board (ESP 32 - C3) on the board manager of Arduino IDE?
If that is the problem you are facing. have you installed the ESP32 boards package by Espressif Systems?
Hi - Yes I did that.
Was looking for Waveshare ESP32 C3 Zero specifically - cant find.
So I am using ESP32C3 Dev Module - as closest match.
-I can down load over USB ...
When I run BLINK led does not light -
Looks as if LED is not mapped in the code Example? - not had this before with Dev boards - BLINK is the hello world of dev boards.
No error in compile or DL.
code..
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
There are several C3 variants in the library's variant directory.
Looking at Waveshare's pinout page, the LED appears to reside at pin 10.
Thanks - I see its a tri colour led.
Did get it going I found some DEMO code on the Waveshare pages - I copied across.
I did have Analog read and send on Serial - working but cant anymore.
Tricky blighter this.
I am not sure if this is your problem or not, but if you go to the paragraph labeled "3." it says: ESP32-C3-Zero does not have USB to UART chip mounted, you need to use the USB of ESP32-C3 as the download interface and Log print interface, and you need to enable USB CDC when using Arduino IDE.
There is a diagram showing what option to choose in the IDE.
Thanks I ran this - stable mostly. When loading other examples they have the USB off by default - so need to put back on.
Serial plot seems a little hit and mis. Often need to restart IDE and go again.
I want to put analog samples over Blutooth to display moving coil type display on phone SW called REMOTE XY.
Tried it on OSB C to C lead but does not like it.
Will try to find a BT Fn and put that in as the serial and see it it fires up !
You probably know this, but your board only supports BLE and not Bluetooth Classic.
Whenever you post your code always use code tags. It makes it much easier to interpret.
Go through this post this should help you to learn to post your code in code tags and also contains a lot of useful information
@tryagaindad tried but used ticks (''') instead of back ticks (```). I've fixed it.
Yes I searched my keyboard for Back ticks but I cant find them.
Under the ~ on my keyboard.
Else just click the <CODE/> button in the composer window.
hi, my ~ key has # too. I will need to write '<'code>
Generally find this stuff overwhelming !
I got Adafruit Trinket to BT samples to Phone (but then it didnt BT - so Bought add on card) Need to revisit that.
Then found ESP32 C3 Zero as it did BT - but seems wrong type of BT for use with REMOTE-XY. Cant quite get that going.
Someone said need to Pay for Remote XY - hadnt seen that?
If I try sending Samples over USB to Phone Running REMOTE-XY this didnt work as comms panel/log could not recognise the samples as serial data ?
Might just use a DMM and wires to read the volts I require. BT would have been nice.
Where I got to last night with the PROJECT.ino file from REMOTE XY code example...
There is a header file needed that is not in the associated Library pack - so fails
"#include <SoftwareSerial.h>" trawled for this for an age.
There is a software serial library for the ESP32. Search for EspSoftwareSerial in the IDE's library manager.
Also, Remote XY does support BLE. This is from their examples page.
