1 year ago You need to create the MD_MAX72xx object in the code rather (using new) than as a static object (or use the setModuleType() method) and use the parameters you want at that time. Look at the Dynamic_HW example.
Hi. I want to make a watch with a dot matrix display, which also has a web interface where I can set various things. Among the settings in the web interface, I want to be able to set the type of hardware and the number of matrices used. How can I change these data in code (in loop) if the display is already initialized. I use a Wemos D1 mini. An image with the web interface: https://i.imgur.com/eqHtoRf.png When I change the hardware type in the web interface, for the hardware type I get an integer variable 1, 2, 3, 4. Depending on these numbers I want to initialize the display with different types of hardware, so that my code can be used on different types of hardware. For Max_Devices from the web interface, I get an integer variable from the web interface, depending on which to set (on the fly) Max_devices from the code. I mention that the display is initialized as follows:
define HARDWARE_TYPE MD_MAX72XX::FC16_HW
define MAX_DEVICES 4
define CLK_PIN 14
define DATA_PIN 13
define CS_PIN 15
MD_Password P = MD_Password(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
