NOTE: You cannot use PSRAM to expand the amount of memory available to use by this library. If you are going to use large/combined panels make sure to check for memory constraints. Check Build Options document for reference. More Information Build-time optionsĪlthough Arduino IDE does not seem to offer any way of specifying compile-time options for external libs there are other IDE's (like PlatformIO/ Eclipse) that could use that. Note: Requires the use of PlatformIO, which you should probably use if you aren't already. This sketch draws simple colors/lines/gradients over the entire matrix and it could help to troubleshoot various issues with ghosting, flickering, etc. Once this is working, refer to the PIO Test Patterns example. You must call begin() before you call ANY pixel-drawing (fonts, lines, colours etc.) function of the MatrixPanel_I2S_DMA class. Run a Test Sketchīelow is a bare minimum sketch to draw a single white dot in the top left. Please contact or order these products from the respective authors. Various people have created PCBs for which one can simply connect an ESP32 to a PCB, and then the PCB to the HUB75 connector, such as: HUB75_I2S_CFG::i2s_pins _pins= ĭma_display = new MatrixPanel_I2S_DMA(mxconfig) #define E_PIN -1 // required for 1/32 scan panels, like 64圆4. Wiring ESP32 with the LED Matrix Panelīy default the pin mapping is as follows (defaults defined in ESP32-HUB75-MatrixPanel-I2S-DMA.h). Or just add it into platformio.ini lib_depth section.Ģ.

There is a virtual panel class available to work with 16x32 panels (see: examples/16x32 Panel.Please use an alternative library if you bought one of these. RUL5358 / SHIFTREG_ABC_BIN_DE based panels are not supported.1/8 Scan LED Matrix Panels are not supported.

Panel driver chips known to be working well Please do not raise issues with respect to panels not supported on the list below. Ones interested in internals of such matrices could find this article useful.ĭue to the high-speed optimized nature of this library, only specific panels are supported. 32x16 pixel 1/4 Scan LED Matrix 'Indoor' Panel using an ingenious workaround as demonstrated in the 32x16_1_4_ScanPanel example.64圆4 pixel 1/32 Scan LED Matrix 'Indoor' Panel.64x32 (width x height) pixel 1/16 Scan LED Matrix 'Indoor' Panel, such as this typical RGB panel available for purchase.RISC-V ESP32's (like the C3) are not, and will never be supported as they do not have parallel DMA output required for this library. Support also exists for the ESP32-S2 and ESP32-S3. If you want to use this library, use with an original ESP32 as it has the most SRAM for DMA. This MCU has 520kB of SRAM which is much more than all the recent 'reboots' of the ESP32 such as the S2, S3, C3 etc. That being the ESP-WROOM-32 module with ESP32‑D0WDQ6 chip from 2017. This library supports the original ESP32. ESP32 SupportedĮspressif have kept the 'ESP32' name for all their chips for brand recognition, but their new variant MCU's are different to the ESP32 this library was built for. OK, OK, than what's the price for those features?" I'll tell you - " memory, you pay it all by precious MCU's memory for DMA buffer". Adafruit GFX API - library could be build with AdafruitGFX, simplified GFX or without GFX API at all.CIE 1931 luminance correction (aka natural LED dimming).Variable color depth - up to TrueColor 24 bits output is possible depending on matrix size/refresh rate required.
