In my previous attempt, I connected the microcontroller to the SD card module as follows:ĭid I properly connect the SD card to the microcontroller? What are CMD and CD? What do D0 to D3 serve? How would SDIO look like the configuration and physical connections from the microcontroller to the SD card?Īt first I tried it with HAL_SPI_Transmit () and finally with the code below as described at.
#Interupts spi arduino due sd card how to
My problem is that I have not yet seen any reasonable documentation that tells me how to properly connect the SD card to a microcontroller. As a microcontroller I use the STM32L073RZT6 and the SD card module from Waveshare, which has an SDIO and SPI interface. Now I try to write data to an SD card, unfortunately so far without success. So far, I was able to successfully implement SPI and I2C on a temperature sensor. Ignore the function related to the button, I removed most of its code to avoid cluttering the page.I am new to the world of stm and STM32CubeMX. Display (pin 13, pin 11, pin A1, pin 12, pin A0 ) In this setup that I'm showing I will initialize the SD in the setup() and in the loop using a button I'm supposed to write stuff on the display: //Libraries I am not familiar with the internal workings of the Due SPI library to be sure.

You should have the SPI operations outside the interrupt and just update some variables and set a flag in your interrupt. The problem is that once the program execute SD.begin() the display stops working and the SPI communication is working only on the SD. Probably SPI transfers use an interrupt, which can't trigger because you're already in an interrupt. I'm having trouble trying to make the double SPIs work and since I'm not really familiar with the libraries that I used I decided to ask for help SPI SRAM shield and a Sparkfun micro SD card shield up to the Arduino Due. wav file on my Arduino Uno via an SD card while at the same time using an LCD display (Nokia 5110). If you dont pass any argument to the begin() function, it will try to initialize SPI communication with the microSD card on the default chip select (CS) pin. In doing so I lost access to the excellent QuadRAM memory expansion board.
