I have bought a Dazzler (module, not shield) and I am trying to get it working with a Teensy 4.0. If I just power it up, I do get the 'splash screen' as expected, but once I also make the SPI connections, it goes to 'no signal' on the screen, suggesting that something is happening, but not much.
I am using the normal GD2.h downloaded from the internet, and am trying to run the standard helloworld demo sketch (both version 1.3.4). I have connected the pins as shown below:
• Teensy 12 to Dazzler 22 SPI out (MISO)
• Teensy 11 to Dazzler 28 SPI in (MOSI)
• Teensy 13 to Dazzler 29 SPI in (SCK)
• Teensy 10 to Dazzler 25 SPI in (GPU SEL) (and I changed one line in GD2.h from #define DEFAULT_CS 8 to #define DEFAULT_CS 10). I have also tried using Dazzler pin 27 (DAZZLER SEL).
Plus GND and 5V. The code is shown below; the sketch only gets as far as GD.begin(), where it just hangs. Any users of the same combination who have made it work, please?
#include <EEPROM.h>
#include <SPI.h>
#include <GD2.h>
#define CS 10
void setup() {
Serial.begin(9600);
Serial.println("test1");
GD.begin();
Serial.println("test2");
}
void loop() {
}
