Конфликт экрана n5110 и SD карты

Pin · 2016-03-30 19:20:03

Подключил экран и карту памяти на SPI.
Экран работает, карта определяется.
Но если попробовать что-то вывести на экран после работы с картой, то ничего не будет, экран даже не очистится.
В чем проблема?
ATmega328
Вот скетч:

/*
  SD card test
 
 This example shows how use the utility libraries on which the'
 SD library is based in order to get info about your SD card.
 Very useful for testing a card when you're not sure whether its working or not.
 
 The circuit: 
  * SD card attached to SPI bus as follows:
 ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
 ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
 ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
 ** CS - depends on your SD card shield or module.
        Pin 4 used here for consistency with other Arduino examples

Из-за таймера в коде работы с картой памяти (в ардуино иде), нельзя подключить больше устройства на аппаратный spi.

NoName · 2016-03-31 11:23:25

Pin, а покажите пруф, мне просто интересно
ведь когда операция чтения / записи завершена - доступ к шине может быть освобожден,
хотя я бы лично не параллелил к карточке что либо, невнятные глюки в таком случае могут свести с ума ) всегда можно сделать программный SPI для менее скоростного оборудования
