Re: Heltec wifi kit32, hardware serial

This works fine for me:

Code: Select all

HardwareSerial Pzemserial(2);
#define RXD2 16 //Gpio pins Serial2
#define TXD2 17
Pzemserial.begin(9600, SERIAL_8N1, RXD2, TXD2);

Re: ESP32 interfaced with currnet sensor acs712 on rtos platform

Keep in mind that the asc712 works on 5V and the Esp32 on 3.3V So if you feeding the sensor with 5V you have to reduce the output to the 3.3V scale with a voltage divider. What current are you measuring AC, DC? If you want to measure energy consumption please have a look at my blog for the Pzem-016 .

Re: ESP32 and AT24C08 EEPROM

Hi,

Be sure you have the eeprom in the correct voltage range. You nedd the one that can work from 2.7V.
Here is some code that should work. https://playground.arduino.cc/code/I2CEEPROM

Re: i2c display garbage

Hi Thanks for your reply, First I used a library from Thingpulse https://github.com/ThingPulse/esp8266-oled-ssd1306 After that I changed to U8x8lib that's from the same maker as U8g2lib.h. Also tested the Graphicstest.ino from the U8g2lib, same problem. All the above lib's working fine until you put...
