Compile the examples in C

[mabiven]

Hello,

I'd like to compile and run the programs in C.
I have an error with the "spi.h" include.

$ gcc real_time.c -o real_time
real_time.c:4:10: fatal error: spi.h: Aucun fichier ou dossier de ce type
#include "spi.h"
^~~~~~~

Can you help me with this problem?
Thank you
Marc

Hi @mabiven generally I didn't use a long time this library and stopped supporting it because a many problem with compilation, but I'll try to figure it out after the holidays

I successfully compiled the program 1.Read_data.c with the following command:

gcc -I ~/c-periphery/src ~/c-periphery/src/gpio_sysfs.c ~/c-periphery/src/spi.c ~/c-periphery/src/gpio.c 1.Read_data.c

When running, I have the error:

spi_open_error_ADS1299 dont send dataADS1299 dont send dataADS1299 dont send dataADS1299...

Does the script run on your side?

Cheers,

Marc

Hi @marc-abiven I used 4 years ago last time,

Generally, just python scripts is works, to confirm that everything is ok ?

Did you turn SPI in the Jetson Nano?

[marc-abiven]

The python script (1.Graph_real_time.py) works.
I enabled SPI1 and SPI2 with sudo python /opt/nvidia/jetson-io/jetson-io.py.
spidev is also loaded with modprobe spidev.
