Hi everyone! I'm new to the forum and teensy/arduino. I have a general question on how I can connect multiple SPI devices, would this work?
Teensy 4.1
SCK - Pin 13
MOSI - Pin 11
MISO - Pin 12
CS1 - Pin 10 (External SD card)
CS2 - Pin 36 (HSCDRRV001PDSA3 - Honeywell differential pressure sensor)
CS3 - Pin 37 (HSCDRRV001PDSA3 - Honeywell differential pressure sensor)
Also, on this link:
https://www.pjrc.com/better-spi-bus-design-in-3-steps/
It states that I should use pull up resistors. What value would be suitable?
Thanks in advance!
Regards,
Neel
