For a project in school my teacher recommended I try to do it with SMD components. I am giving it a shot and while working on the circuit I came into a problem. I've always programmed my MCU from the STK500 but for this project I want to put in the ISP header for programming the MCU.
The heart of the project is the MCU interfacing with the SD card through the SPI pins.
I figured the SD card would have to be removed while I was programming since the MCU is programmed at 5V and the SD card runs at 3.3V but I am not sure if the pull-up resisters required to control the SD card would affect the ISP.
If not would my current circuit design work? (labeled 1)
If not would the second circuit design fix the issue? (labeled 2) I added a switch to connect the 5v or SD power.
Thanks in advance.
