If you want to use Jinx to control LEDs display:.
Download and install the software (it don't need administrative priviledge 😉)
Go to Setup > Matrix options. Then, in matrix diemnsion, edit the matrix size to match with yours.
Go to Setup > Output devices. Click Add. Then, fill the form as following: Device type: tpm2.net IP Address: Check your router. Or, if you attach FTDI, see the line IP Address: in the Serial console. Data > Channels & Chan/Block: At lease (3 * width * height) + 7. Each pixel need 3 bytes (Red, Green, Blue), 7 bytes is for TPM2.net prefix and end byte. Jinx will send data as a user data and raw bytes of pixels. Excess bytes'll be ignored by default. And, since I'm too lazy to handle multiple data blocks, I'll just assume that the whole frame is in one block.
Go to Setup > Output patches. It'll display red pixel grid, which is unpatched pixels. Click Fast patch. Fill the following values: Dimension: x: matrix width, y: matrix height. (That means we want to transmit the whole frame) Make sure the Starting pixel at is 1/1. If not, go back to patch grid, and click the top-left corner pixel. Patch mode: depend on how you wire your strip's data line chain. In my case, I connect the first DIN (Data in) to the Top-right corner (I know it's weird, but I'm confuse while connectingit together, and I'm mess up the order. So, to save my time, I connect it that way. 😑) and, to reduce data line length and minimize capacitance interference, I connect each pixel as a zig-zag pattern. (First column is on the right, even lines are top-to-bottom, odd lines are bottom-to-top.) So, I choose Snakecolumns starting Top-Right. Pixel order: RGB First channel: 0 Patch device: Your device.
On Channel 1 / Effect 1, select simple color. It'll show red color in every pixels.
Go to Setup > Start Output. If your setup is right, the matrix should illuminate red in every pixels.
On Channel 1 / Effect 1, Click edit. Swap to each others main colors. If the color's display incorrectly, change Pixel order in Output patches.
To prevent overcurrect, on the bottom center of the program, slide Master down to the acceptable degree.
If everything's looks good, OPEN THE DISCO FLOOR BABY!
