Hi, Is anybody here to tell me how to use the UART1 (GPIO9 & GPIO10)? By default, only UART0 and UART2 can be used. To use UART1, we have to redefine the pins because default pins of UART1 such as GPIO9 and GPIO10 are internally connected to the SPI flash memory. What is the meaning of "redefine"? T...

Here is the solution:
Serial.begin(115200);
Serial.print("MOSI: ");
Serial.println(MOSI);
Serial.print("MISO: ");
Serial.println(MISO);
Serial.print("SCK: ");
Serial.println(SCK);
Serial.print("SS: ");
Serial.println(SS);

Thank you for your quick answer,
but in my example code there are only 2 GPIO's
#define SS_PIN 5
#define RST_PIN 0

How to handle MISO & MOSI???

Hi,
I'm just working with the ESP32 C3 DEVKIT but I can't find the right ports
for MOSI, MISO, SCK and SS on the devboard!

Thank you for any help,
Bernd

I've solved my problem!
I think that the GND of the controller didn't have connection after soldering.
Now it works fine!

Hello, I'm trying to flash an ESP32-C3FN4 controller via an ESP32-C3-DEVKITM1 (without an "ESP32-C3 Mini1" board). I've connected my board to the devkit (3V3, GND, EN, GPIO9, TX and RX). I don't know how to connect the "SPI" pad. When I connect the ESP32-C3 Mini1 board it works right and I'm able to...

Hi,
I would like to flash only an ESP32-C3 controller via wire and the ESP32-C3-DevKitM-1.
Do I need an extern Memory (4Mb) in this case for my single controller?
Is there are a better solution to flash my controllers.

Many thanks!

Hello,

I'm going to flash the controller via ESP-PROG Board.
Do I need an external quartz for the controller in this case?

Thank you for help!

Thank you for the quick answer! I bought this programmer: (https://www.amazon.de/iHaospace-ESP-Prog-Program-Downloader-Development/dp/B097N1BZRK/ref=sr_1_5?adgrpid=1199567836504409&hvadid=74973107844740&hvbmt=be&hvdev=c&hvlocphy=128206&hvnetw=o&hvqmt=e&hvtargid=kwd-74973187238931%3Aloc-72&hydadcr=16...

Thank you to be here! I'm familiar with ATMEL and ARM-controller but now I'm interested in ESP32-c3. I do need help for the first steps because I'm going to use the ESP32-c3 without the DEV-kid's. Only the controller! What kind of programmer do I need? Could I use VS code? How could I debug my code?...
