Hello
I need help!!! I try to make works a led panel (128*64) , 1/32 scan (with E pin) with this chips : fm6124, tc7258en, 74hc245.
I use a teensy 3.6 whith smartmatrix V4.
I see only red color !!! I try with another cable… whith arduino i can see red, green and bleu… (but make random pixel)…
the code for exemple:
if i change the setBrightness
matrix.setBrightness((100255)/100); //brightness);
to
matrix.setBrightness((99255)/100); //brightness);
the text become illegible
// only for testing
#include <SmartLEDShieldV4.h>
#include <SmartMatrix3.h>
#define COLOR_DEPTH 24 // known working: 24, 48 - If the sketch uses type rgb24 directly, COLOR_DEPTH must be 24
const uint8_t kMatrixWidth = 128;
const uint8_t kMatrixHeight = 64;
const uint8_t kRefreshDepth = 36; // known working: 24, 36, 48
const uint8_t kDmaBufferRows = 4; // known working: 2-4, use 2 to save memory
const uint8_t kPanelType = SMARTMATRIX_HUB75_64ROW_MOD32SCAN; // use SMARTMATRIX_HUB75_16ROW_MOD8SCAN for common 16x32 panels, or use SMARTMATRIX_HUB75_64ROW_MOD32SCAN for common 64x64 panels
const uint8_t kMatrixOptions = (SMARTMATRIX_OPTIONS_NONE); // see http://docs.pixelmatix.com/SmartMatrix for options
const uint8_t kBackgroundLayerOptions = (SM_BACKGROUND_OPTIONS_NONE);
const uint8_t kScrollingLayerOptions = (SM_SCROLLING_OPTIONS_NONE);
const uint8_t kIndexedLayerOptions = (SM_INDEXED_OPTIONS_NONE);
SMARTMATRIX_ALLOCATE_BUFFERS(matrix, kMatrixWidth, kMatrixHeight, kRefreshDepth, kDmaBufferRows, kPanelType, kMatrixOptions);
SMARTMATRIX_ALLOCATE_BACKGROUND_LAYER(backgroundLayer, kMatrixWidth, kMatrixHeight, COLOR_DEPTH, kBackgroundLayerOptions);
SMARTMATRIX_ALLOCATE_SCROLLING_LAYER(scrollingLayer, kMatrixWidth, kMatrixHeight, COLOR_DEPTH, kScrollingLayerOptions);
SMARTMATRIX_ALLOCATE_INDEXED_LAYER(indexedLayer, kMatrixWidth, kMatrixHeight, COLOR_DEPTH, kIndexedLayerOptions);
//====================================================
void setup() {
matrix.addLayer(&backgroundLayer);
matrix.begin();
backgroundLayer.enableColorCorrection(true);
backgroundLayer.fillScreen({0, 0, 0});
backgroundLayer.drawString(0, 1, {255, 255, 255}, "Line1"); //{255, 255, 255} White
backgroundLayer.drawString(0, 16, {255, 215, 0}, "Line2"); //{255, 215, 0} Yellow
backgroundLayer.drawString(0, 34, {255, 255, 255}, "Line3");
backgroundLayer.drawString(0, 49, {0, 255,255}, "Line4");
matrix.setBrightness((100*255)/100); //brightness);
backgroundLayer.swapBuffers();
}
//====================================================
void loop() {
while(1);
}
thank you to reading me !!!
