Platformio support #19
Comments

Hi @bubulgum, I think this library can be used in PlatformIO as follows. What issue are you encountering? In platformio.ini file: |
I'm using it with CH422G. On Arduino IDE this example works fine: But with Palformio have a lot of issues: |
|
The ... |
this will make more trouble. |
|
It looks like your build environment does not support C++17. Maybe you can use an older version v0.1.0 that does not depend on esp-lib-utils? |
|
I've tried |
|
@bubulgum Please post your platformio.ini The driver needs Arduino 3.x / >=IDF 5.1 so you have to use the Platformio fork pioarduino |
please have a look |
|
Official Platformio only supports Arduino core 2.0.17. So the config can not work. |
Thank you for your support, after core was updated, everything work on Platformio. |

Could you provide more support, i could make working LEDs and buttons on my board with ESP32C3 with CH422 and library. #include <Arduino.h>
#include <esp_io_expander.hpp>
#define EXAMPLE_I2C_SDA_PIN (10)
#define EXAMPLE_I2C_SCL_PIN (4)
#define EXAMPLE_I2C_ADDR (ESP_IO_EXPANDER_I2C_CH422G_ADDRESS) // default 0x24
esp_expander::CH422G *expander = NULL;
// Pin definitions for buttons
#define BUTTON_PIN_1 8
#define BUTTON_PIN_2 2
#define BUTTON_PIN_3 7
#define BUTTON_PIN_4 6
#define BUTTON_PIN_5 5
void setup() {
Serial.begin(115200);
delay(1000);
Serial.println("Test begin");
expander = new esp_expander::CH422G(EXAMPLE_I2C_SCL_PIN, EXAMPLE_I2C_SDA_PIN, EXAMPLE_I2C_ADDR);
expander->init();
expander->begin();
// Set all pins 0-7 as outputs for LEDs
expander->enableAllIO_Output();
// Set button pins as inputs with pull-up resistors

pinMode(BUTTON_PIN_4, INPUT_PULLUP);

// All LEDs are off by default (HIGH)
expander->digitalWrite(0, HIGH); // Turn off LED on pin IO0
expander->digitalWrite(2, HIGH); // Turn off LED on pin IO2
expander->digitalWrite(4, HIGH); // Turn off LED on pin IO4
expander->digitalWrite(6, HIGH); // Turn off LED on pin IO6

Serial.println("LEDs on IO0, IO2, IO4, IO6, and OC0 are set to output mode.");
}
void loop() {
// Check the button states and turn on corresponding LEDs
if (digitalRead(BUTTON_PIN_1) == LOW) { // Button 1 pressed (LOW is active)
expander->digitalWrite(1, LOW); // Turn on LED on pin IO0
Serial.println("Button 1 pressed, LED IO0 ON");
} else {
expander->digitalWrite(1, HIGH); // Turn off LED on pin IO0
}

expander->digitalWrite(3, LOW); // Turn on LED on pin IO2
Serial.println("Button 2 pressed, LED IO2 ON");
} else {
expander->digitalWrite(3, HIGH); // Turn off LED on pin IO2
}
if (digitalRead(BUTTON_PIN_3) == LOW) { // Button 3 pressed
expander->digitalWrite(5, LOW); // Turn on LED on pin IO4
Serial.println("Button 3 pressed, LED IO4 ON");
} else {
expander->digitalWrite(5, HIGH); // Turn off LED on pin IO4
}
if (digitalRead(BUTTON_PIN_4) == LOW) { // Button 4 pressed
expander->digitalWrite(7, LOW); // Turn on LED on pin IO6
Serial.println("Button 4 pressed, LED IO6 ON");
} else {
expander->digitalWrite(7, HIGH); // Turn off LED on pin IO6
}
if (digitalRead(BUTTON_PIN_5) == LOW) { // Button 5 pressed
expander->digitalWrite(9, LOW); // Turn on LED on pin OC0
Serial.println("Button 5 pressed, LED OC0 ON");
} else {
expander->digitalWrite(9, HIGH); // Turn off LED on pin OC0
}
delay(100); // Delay to prevent button debounce
}Scan I2C found this address: Looks like all belong to CH422G, But I also have OLED display on this board that using I2C with same SDA and SCL on address 0x3C. So my question is: How put CH422G to SLEEP mode using library? |
|
Hi @bubulgum, CH422G currently does not support entering sleep mode. I have added this feature in the feat/ch422g_support_sleep branch, please give it a try. |

Hi. please make library for Platformio with CH422G. thx
