Evening all..
I am trying to run a SSD1322 OLED (using the U8g2 library) and a PGA2311 audio pre-amp IC on a ESP32.
The PGA2311 works fine but the issue is when I include the PGA2311's pinModes, it prevents the OLED from displaying anything. If I comment out the pinMode lines, the OLED works - but obviously the PGA2311 now doesn't.
I've enabled U8G2_16BIT in u8g2.h file.
My guess is something around the HW SPI and I've researched the hell out of this and tried a million different things but seem to be missing something.
Can anyone please point me in the right direction, even if it's what to read or research...
#include <U8g2lib.h>
//#ifdef U8X8_HAVE_HW_SPI
#include <SPI.h>
//#endif
//#ifdef U8X8_HAVE_HW_I2C
#include <Wire.h>
//#endif
// PGA2311 Pre Amp Pins
#define PGA_SCLK_PIN 18
#define PGA_CS_PIN 22
#define PGA_SDI_PIN 23
U8G2_SSD1322_NHD_256X64_F_4W_HW_SPI u8g2(U8G2_R0, /* cs=*/ 12, /* dc=*/ 14, /* reset=*/ 27); // Enable U8G2_16BIT in u8g2.h
void setup(void) {
u8g2.begin();
//PGA2311 Pins
pinMode(PGA_CS_PIN, OUTPUT); //initialize pins
pinMode(PGA_SCLK_PIN, OUTPUT);
pinMode(PGA_SDI_PIN, OUTPUT);
digitalWrite(PGA_CS_PIN, HIGH);
digitalWrite(PGA_SCLK_PIN, HIGH);
digitalWrite(PGA_SDI_PIN, HIGH);
}
void loop(void) {
u8g2.clearBuffer(); // clear the internal memory
u8g2.setFont(u8g2_font_ncenB08_tr); // choose a suitable font
for (int i = 0; i < 200; i++) {
u8g2.drawStr(i, 10, "Hello World!"); // write something to the internal memory
u8g2.sendBuffer(); // transfer internal memory to the display
}
}
