Possible values // are 4, 6, 8, 10, 12, ... Smaller values are faster. On my Waveshare35b display, the // following values were observed to work (on a Pi 3B): // core_freq=400: CDIV=14, results in 28.57MHz // core_freq=255: CDIV=8, results in 31.875MHz // While the following values were seen to not work: // core_freq=400: CDIV=12, would result in 33.33MHz, but this was too fast for the display // core_freq=256: CDIV=8, would result in 32.00MHz, this would work 99% of the time, but occassionally every ~few minutes would glitch a pixel or two #if !defined(GPIO_TFT_DATA_CONTROL) #define GPIO_TFT_DATA_CONTROL 24 #endif #if !defined(GPIO_TFT_RESET_PIN) #define GPIO_TFT_RESET_PIN 25 #endif #endif
