How to display 5x5 Font at Led Strip Neopixel 5 Row many Coloum?

Other Hardware LEDs and Multiplexing
1

I'm trying to display text (sentences) in Led Strip Neopixel which has 5 rows, with any column (at least 5 columns).

I am using the Font that attached in this topic.

I'm using a NodeMCU ESP32-S board or a NodeMCU ESP8266 board.

Maybe here someone can help me for the basic sketch.
Thanks.

uint8_t FontData[95][5] =

You have posted the font definition but no code where you attempt to use it. Have you actually tried to use it ?

A schematic showing how the Neopixels are connected to the board and how they are powered would also be helpful

While i try with my code like this, just for check to Serial.print:

/*
Learn to write text on LedStrip Neopixel
*/

#include <Adafruit_NeoPixel.h>
#include <Adafruit_NeoMatrix.h>
#include <Font5x5.h>
#ifdef __AVR__
#include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif

#define LED_PIN 13
#define MTRX_ROW 5
#define MTRX_COL 60
#define LED_COUNT (MTRX_ROW * MTRX_COL)

Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

uint8_t Font5x5[95][5] 
{
  {
    0b01100, // A
    0b10010,
    0b10010,
    0b11110,
    0b10010
  },
};

void setup() {
  Serial.begin(115200);  
}

void loop() {
  readSentences('A');  
}

void readSentences(byte sentences)
{
  for (int row = 0; row < 5; row++)
  {
    for (int bit = 7; bit >= 0; bit--)
    {
      if (bitRead(Font5x5[sentences][row], bit) == 1)
      {
        Serial.print("X");
      }
      else
      {
        Serial.print(" ");
      }
    }
    Serial.println();
  }
}

If that code works then where are you stuck ?

How are the Neopixels arranged ?

If they are all in one long strand mounted in rows then you can derive the number of the pixel to write to from the row and bit numbers of the font matrix using division and the modulo operator

Alternatively there are libraries to help you, although I have never used them. Foe instance, take a look at NeoMatrix Library | Adafruit NeoPixel Überguide | Adafruit Learning System

I can't display a sentence, it can only be one letter

okey, thx, I will try...
