For example, the WS2812B-2020 has physically swapped red and green LEDs, which causes the wrong color to be displayed, because the default order of the bytes sent over the wire is defined as GRB. In this case, you can change the byte order by defining `WS2812_BYTE_ORDER` as one of the following values: -| Byte order | Known devices | -|-----------------------------------|-------------------------------| -| `WS2812_BYTE_ORDER_GRB` (default) | Most WS2812's, SK6812, SK6805 | -| `WS2812_BYTE_ORDER_RGB` | WS2812B-2020 | +|Byte order |Known devices | +|---------------------------------|-----------------------------| +|`WS2812_BYTE_ORDER_GRB` (default)|Most WS2812's, SK6812, SK6805| +|`WS2812_BYTE_ORDER_RGB` |WS2812B-2020 | +|`WS2812_BYTE_ORDER_BGR` |TM1812 | ### Bitbang diff --git a/drivers/chibios/ws2812.c b/drivers/chibios/ws2812.c index 59ed90374a..0d12e2fb79 100644 --- a/drivers/chibios/ws2812.c +++ b/drivers/chibios/ws2812.c @@ -97,6 +97,10 @@ void ws2812_setleds(LED_TYPE *ledarray, uint16_t leds) { sendByte(ledarray[i].r); sendByte(ledarray[i].g); sendByte(ledarray[i].b); +#elif (WS2812_BYTE_ORDER == WS2812_BYTE_ORDER_BGR) + sendByte(ledarray[i].b); + sendByte(ledarray[i].g); + sendByte(ledarray[i].r); #endif #ifdef RGBW diff --git a/drivers/chibios/ws2812_pwm.c b/drivers/chibios/ws2812_pwm.c index 3af922c063..140120d488 100644 --- a/drivers/chibios/ws2812_pwm.c +++ b/drivers/chibios/ws2812_pwm.c @@ -180,6 +180,43 @@ * @return The bit index */ # define WS2812_BLUE_BIT(led, bit) WS2812_BIT((led), 2, (bit)) + +#elif (WS2812_BYTE_ORDER == WS2812_BYTE_ORDER_BGR) +/** + * @brief Determine the index in @ref ws2812_frame_buffer "the frame buffer" of a given red bit + * + * @note The red byte is the middle byte in the color packet + * + * @param[in] led: The led index [0, @ref RGBLED_NUM) + * @param[in] bit: The bit number [0, 7] + * + * @return The bit index + */ +# define WS2812_RED_BIT(led, bit) WS2812_BIT((led), 2, (bit)) + +/** + * @brief Determine the index in @ref ws2812_frame_buffer "the frame buffer" of a given green bit + * + * @note The red byte is the first byte in the color packet + * + * @param[in] led: The led index [0, @ref RGBLED_NUM) + * @param[in] bit: The bit number [0, 7] + * + * @return The bit index + */ +# define WS2812_GREEN_BIT(led, bit) WS2812_BIT((led), 1, (bit)) + +/** + * @brief Determine the index in @ref ws2812_frame_buffer "the frame buffer" of a given blue bit + * + * @note The red byte is the last byte in the color packet + * + * @param[in] led: The led index [0, @ref RGBLED_NUM) + * @param[in] bit: The bit index [0, 7] + * + * @return The bit index + */ +# define WS2812_BLUE_BIT(led, bit) WS2812_BIT((led), 0, (bit)) #endif /* --- PRIVATE VARIABLES ---------------------------------------------------- */ diff --git a/drivers/chibios/ws2812_spi.c b/drivers/chibios/ws2812_spi.c index a933424362..89df2987b5 100644 --- a/drivers/chibios/ws2812_spi.c +++ b/drivers/chibios/ws2812_spi.c @@ -70,6 +70,10 @@ static void set_led_color_rgb(LED_TYPE color, int pos) { for (int j = 0; j < 4; j++) tx_start[BYTES_FOR_LED * pos + j] = get_protocol_eq(color.r, j); for (int j = 0; j < 4; j++) tx_start[BYTES_FOR_LED * pos + BYTES_FOR_LED_BYTE + j] = get_protocol_eq(color.g, j); for (int j = 0; j < 4; j++) tx_start[BYTES_FOR_LED * pos + BYTES_FOR_LED_BYTE * 2 + j] = get_protocol_eq(color.b, j); +#elif (WS2812_BYTE_ORDER == WS2812_BYTE_ORDER_BGR) + for (int j = 0; j < 4; j++) tx_start[BYTES_FOR_LED * pos + j] = get_protocol_eq(color.b, j); + for (int j = 0; j < 4; j++) tx_start[BYTES_FOR_LED * pos + BYTES_FOR_LED_BYTE + j] = get_protocol_eq(color.g, j); + for (int j = 0; j < 4; j++) tx_start[BYTES_FOR_LED * pos + BYTES_FOR_LED_BYTE * 2 + j] = get_protocol_eq(color.r, j); #endif } diff --git a/quantum/color.h b/quantum/color.h index 7448168b3a..4783f6839c 100644 --- a/quantum/color.h +++ b/quantum/color.h @@ -37,6 +37,7 @@ #define WS2812_BYTE_ORDER_RGB 0 #define WS2812_BYTE_ORDER_GRB 1 +#define WS2812_BYTE_ORDER_BGR 2 #ifndef WS2812_BYTE_ORDER # define WS2812_BYTE_ORDER WS2812_BYTE_ORDER_GRB @@ -51,6 +52,10 @@ typedef struct PACKED { uint8_t r; uint8_t g; uint8_t b; +#elif (WS2812_BYTE_ORDER == WS2812_BYTE_ORDER_BGR) + uint8_t b; + uint8_t g; + uint8_t r; #endif } cRGB; @@ -66,6 +71,10 @@ typedef struct PACKED { uint8_t r; uint8_t g; uint8_t b; +#elif (WS2812_BYTE_ORDER == WS2812_BYTE_ORDER_BGR) + uint8_t b; + uint8_t g; + uint8_t r; #endif uint8_t w; } cRGBW; |
