0730-0800 Absen Pagi hanya absen pagi
0800-0900 >>Buat presentasi untuk RIIM 4 bu Nazarina direncanakan 6-10 Halaman
(baru selesai 3 halaman) perlu ditambah kan program random nerd
0900-1200 Buat program ESP8266 sd card
program untuk mengetes bukan pakai ESP8266 akan tetapi mengunakan ESP32
https://wokwi.com/projects/388854830688347137
perlu diingat pin CS untuk komunikasi SPI adalah pada 5
program dicoba pada ESP8266 yang real sedangkan pin out yang dipergunakan adalah
https://newbiely.com/tutorials/esp8266/esp8266-micro-sd-card
ingat pin CS biasanya mengunakann D8 (jika diarduino IDE akan error) sebenarnya d8 adalah GPIO15 jadi D8 di tulis angka 15 saja
#include <SD.h>
#define CS_PIN 15

char buf[10] ;

Serial.begin(115200);
Serial.print("Inisialisasi SD Card..");
if (!SD.begin(CS_PIN)) {
Serial.println("Gagal load SD card.");
return;
}
Serial.println("OK.");
File textFile = SD.open("/Hello.txt");

Buat RAB buat RISPRO 2024 dan sudah dikirim ke Adit
Komunikasi ESP NOW
ESPNOW adalah komunikasi nirkabel untuk chip ESP untuk lebih detail dapat dilihat dari CHIP
ini adalah pin out dari Weemos D1 mini clone
Di Arduino IDE pergunakan ESP32 WROOM perlu dipencet boot kalau ESP32 tidak perlu
Untuk ESP NOW bisa dipergunakann ESP32 sebagai sender dan ESP8266 reciever
