Hi everyone, I'm using an ESP32-S3 WROOM 1 N16 R8, a P10 RGB HUB75 32*16 1/4 scan panel, and an external 5-volt power supply with common ground. I'm using the ESP32 HUB75 MatrixPanel DMA library, and also tried the P10 fixed fork. The panel isn't working correctly, and I've been troubleshooting for…

Hello. Would you replace your image of code with code in formatted text? Thank you. [paste]

[image] dawxdaw: If anyone has experience with this specific panel or the DP5125D driver IC, I'd really appreciate any advice or recommended configuration. Your problems aren't related to the 5135 driver, so you don't need to look for people with that driver. First, you need to determine the…

About connections: [image] dawxdaw: Wiring, R1 to GPIO4, G1 to 5, B1 to 6, R2 to 7, G2 to 15, B2 to 16, A to 17, B to 18, C to11, D not connected, CLK to 8, LAT to 9, OE to 10, and common ground connected. This list contradicts the code you posted above. Specifically, pin C isn't connected i…

Thank you for your encouragement. I'll try again. I'll upload clear photos of the back of the panel and the chips. Hopefully that will help. [84a97b93-2784-4cc4-bea8-13b574a140a2] [ad030b86-8a08-4683-af3b-8436165ad57c] [0d07abc1-2242-4d2e-8634-de49d72f19b5]

Hi @dawxdaw Thanks for the images. Please show the index of the chip I selected on the picture: [panel3216]
