Markus Sattler	27f45a205a	SD: ... - optimize SPI usage 148% write speed (24kB/s -> 37kB/s) and 127% read speed (121kB/s -> 155kB/s) at 8MHz - add clock frequency as parameter for begin(csPin, frequency) - SD @80MHz write: 84kB/s read: 231kB/s SPI add functions: - void write32(uint32_t data); - void write32(uint32_t data, bool msb); - void transferBytes(uint8_t * out, uint8_t * in, uint32_t size); Adafruit_ILI9341: - code clean	2015-05-10 17:34:16 +02:00
Markus Sattler	070f2b3a14	many speed optimizations in Adafruit_ILI9341 lib (3x times faster) ... add new SPI function: void write(uint8_t data); void write16(uint16_t data); void write16(uint16_t data, bool msb); void writeBytes(uint8_t * data, uint32_t size); void writePattern(uint8_t * data, uint8_t size, uint32_t repeat); Adafruit_ILI9341: | Benchmark | Old (ms) | New (ms) | Speedup | | ------------------------- | -------- | -------- | ----------- | | Screen fill | 1248369 | 278707 | +347,91% | | Text | 86102 | 53785 | +60,09% | | Lines | 825400 | 536374 | +53,89% | | Horiz/Vert Lines | 101875 | 24653 | +313,24% | | Rectangles (outline) | 65720 | 17295 | +279,99% | | Rectangles (filled) | 2592250 | 579157 | +347,59% | | Circles (filled) | 411475 | 179454 | +129,29% | | Circles (outline) | 360002 | 233584 | +54,12% | | Triangles (outline) | 261772 | 170118 | +53,88% | | Triangles (filled) | 866951 | 246237 | +252,08% | | Rounded rects (outline) | 154131 | 81570 | +88,96% | | Rounded rects (filled) | 2828112 | 660983 | +327,86% | | | | | | | Total | 9802159 | 3061917 | +220,13% |	2015-05-09 16:19:32 +02:00
