This program controls up to 16 RGB LED ribbons, use DMA.
This program controls up to 16 RGB LED ribbons. Output is made to port D via DMA on demand from timers. I tested the Starter Kit EFM32GG-STK3700 using LEDs SK6805, can easily be reconfigured for other types of LEDs. The number of LEDs in the tape is specified at the beginning of the program: #define TAPE_LENGHT 144 If anyone should take it - I give it. Project for SEGGER Embedded Studio for ARM Release 3.34 Windows x64 (studio is free for amateur use). The original message in Russian in UTF-8 encoding: Эта программа управляет параллаельно до 16 лент RGB LED. Вывод ведётся на порт D через DMA по зпросу от таймеров. Тестировал на Starter Kit EFM32GG-STK3700 использую светодиоды SK6805, легко может быть перенастроена для других типов светодиодов. Число светодиодов в ленте указвыается в начале программы: #define TAPE_LENGHT 144 Если кому надо берите - дарю. Проект для SEGGER Embedded Studio for ARM Release 3.34 Windows x64 (студия бесплатна для любительского использования). DOC https://www.silabs.com/development-tools/mcu/32-bit/efm32gg-starter-kit#manuals Добавил работу с DS18B20 (датчиком температуры). Теперь на старте надо держать одну из кнопок PB0 или PB1 чтобы стартовала гирлянда, иначе стартует датчиком температуры DS18B20, подключённый к PC6 и 3V3. Также не забываем подтянуть PC6 к +3V3 через 4к7
