Hi all,
been hitting my head against a wall here, hope someone can tell me if what i am proposing to do is possible or if its just plain not possible. I have a adafruit 1.27" SSD1351 display hooked up as follows:
SSD1351 1.27" w/sd adafruit arduino mini
CD ------------------------------------>A0
MISO --------------------------------->8
SCS ----------------------------------->7
OCS ------------------------------------>5
DC ------------------------------------>4
CLK ------------------------------------>2
MOSI ------------------------------------>3
RST ------------------------------------>6
so in conjunction (and reason i don't use hardware SPI) is i have a NRF24L01 connected as follows
NRF24L01 Arduino mini
CE-------------------------------------->9
CSN------------------------------------>10
MOSI----------------------------------->11
MISO----------------------------------->12
SCLK------------------------------------>13
so far i don't have code per say, i have used the "test.ino" from SSD1351 examples to drive the ssd1351 on softwares pi pins and it works fine... but i cannot get the sd card to work (i think because i cannot assign the MISO pin int he SSD1351 call(all others can be pointed to pins).
I have tried using SDfat, but then it does not read the bmp properly when i use the bmp example.
I only need to read the sd card once to display a image, can be in the setup loop... when its in main loop i will never address the sd card. i will just grab info from wireless NRF24L01 as fast as possible (thats why i used hardware SPI) and periodically update text on the OLED display.
so - is it possible? i am not worried about speed for sd card read since i only do it once... can you guys give me some examples or pointers?
thanks,
Spence
