Hi,

I'm trying to use this library with Wiznet LCD1602 screen based on chip AIP31068L. Unfortunately although I'm using I2C library and definition code tries to call SPI settings

/Users/xxx/Documents/Arduino/libraries/LiquidCrystal_AIP31068/LiquidCrystal_AIP31068_SPI.cpp: In member function 'void LiquidCrystal_AIP31068_SPI::begin(uint8_t, uint8_t, uint8_t)': /Users/xxx/Documents/Arduino/libraries/LiquidCrystal_AIP31068/LiquidCrystal_AIP31068_SPI.cpp:83:34: error: 'SPI_CLOCK_DIV2' was not declared in this scope 83 | softspi->setClockDivider(SPI_CLOCK_DIV2); | ^~~~~~~~~~~~~~

The relevant code part is:

include

include

LiquidCrystal_AIP31068_I2C lcd(0x3E, 16, 2);

void setup() {

lcd.init();                   
lcd.setCursor(0,0);
lcd.print("Hello, world!");

}

Im connecting LCD to W5500-EVB-Pico , so raspbery Pi Pico ports GP4 and 5. I2C address was scanned and is correct.

Please help

Hi! Check what version of SoftSPIB library do you use. Update it if possible. Open SoftSPIB's Loopback example, add setClockDivider(SPI_CLOCK_DIV2) and see if it works there. The problem is some platforms do not define SPI_CLOCK_DIVXXX macros any longer.
