Hello, I also bought a Pi 5 and am experiencing the same issues. Here’s my setup, all purchased via Amazon:
Vemico Raspberry Pi 5 8GB Starter Kit: Pi 5 8GB with 64GB card, Raspberry Pi 5 case with fan, Type-C 5.1V 5A power cable, 2 Micro HD out cables, card reader, card adapter, screwdriver
BerryBase 40 Pin GPIO Stacking Header for Raspberry Pi
KEYESTUDIO Raspberry Pi GPIO Cable Extension Board, Solderless Breadboard with 400 tie points, 40-pin Jumper Ribbon Cable for Raspberry Pi 4/3/2/1/Zero/B B+ A A+
What I have discovered so far is that the Pi 5 has an I/O chip that controls the GPIO pins, which the older Pis do not have. Programs using "import RPi.GPIO as GPIO" unfortunately do not work. I came across this post and wanted to build on it.
First of all, I am a complete beginner when it comes to GPIO, and I don't speak English well. I hope ChatGPT is doing its job correctly here, and I apologize in advance for any translation errors. I have followed the steps and will just pass on all the input to you.
Here is a step-by-step guide to checking the SPI functionality on your Raspberry Pi 5:
Step 1: Check if spidev0 is working
Open a terminal.
Run the following command: ls -l /dev/spidev0*
Check if the files /dev/spidev0.0 and /dev/spidev0.1 are listed.
Step 2: Check Pin Configuration
Run this command in the terminal: pinctrl | head -n 14
Verify that GPIO9, GPIO10, and GPIO11 are listed as SPI0_MISO, SPI0_MOSI, and SPI0_SCLK.
Step 3: SPI Loopback Test
Physically connect SPI0_MISO (Pin 21) to SPI0_MOSI (Pin 19).
Open Python: python3
Run the following Python code: import spidev spi = spidev.SpiDev() spi.open(0,0) print(spi.xfer([8,4,2,1,0])) print(spi.xfer([8,4,2,1,0]))
The second spi.xfer call should return [4, 2, 1, 0, 128].
Step 4: CE0 Test
Connect SPI0_MISO (Pin 21) to SPI0_CE0 (Pin 24).
In Python: spi1 = spidev.SpiDev() spi1.open(0,1) print(spi.xfer([8,4,2,1,0])) print(spi1.xfer([8,4,2,1,0]))
spi.xfer should return [0, 0, 0, 0, 0] and spi1.xfer should return [255, 255, 255, 255, 255].
If all steps are successful, SPI is working correctly on your Raspberry Pi 5.
You: pinctrl | head -n 14
Check if GPIO9, GPIO10, and GPIO11 are listed as SPI0_MISO, SPI0_MOSI, and SPI0_SCLK.
9: ip pn | lo // GPIO9 = input
10: ip pn | lo // GPIO10 = input
11: ip pn | lo // GPIO11 = input
ChatGPT:
If the pin configuration check shows GPIO9, GPIO10, and GPIO11 as inputs, it means these pins are not correctly configured as SPI pins. To fix this, you need to ensure the SPI interface is properly enabled and configured.
Steps to Enable SPI:
Enable SPI:
Open the Raspberry Pi configuration tool: sudo raspi-config
Go to Interfacing Options > SPI and enable SPI.
Reboot the Raspberry Pi: sudo reboot
Check Pin Configuration Again:
After rebooting, run pinctrl | head -n 14 again.
Ensure that GPIO9 is configured as SPI0_MISO, GPIO10 as SPI0_MOSI, and GPIO11 as SPI0_SCLK.
Redo SPI Tests:
Follow the steps above to check the SPI functionality again.
If the pins are still not correctly configured after enabling SPI, there might be an issue with the configuration or hardware.
You: pinctrl | head -n 14
0: ip pu | hi // ID_SDA/GPIO0 = input
1: ip pu | hi // ID_SCL/GPIO1 = input
2: a3 pu | hi // GPIO2 = SDA1
3: a3 pu | hi // GPIO3 = SCL1
4: ip pn | lo // GPIO4 = input
5: no pu | -- // GPIO5 = none
6: no pu | -- // GPIO6 = none
7: op dh pu | hi // GPIO7 = output
8: op dh pu | hi // GPIO8 = output
9: a0 pn | lo // GPIO9 = SPI0_MISO
10: a0 pn | lo // GPIO10 = SPI0_MOSI
11: a0 pn | lo // GPIO11 = SPI0_SCLK
12: no pd | -- // GPIO12 = none
13: no pd | -- // GPIO13 = none
ChatGPT:
Yes, this output shows that the GPIO9, GPIO10, and GPIO11 pins are correctly configured as SPI pins:
GPIO9: SPI0_MISO (Master In Slave Out)
GPIO10: SPI0_MOSI (Master Out Slave In)
GPIO11: SPI0_SCLK (SPI Clock)
This means the SPI interface on your Raspberry Pi 5 is active, and the pins are correctly assigned. You can proceed with the further steps to test SPI functionality as described earlier.
