Hey, I am currently checking the documentation for a "How to do an I2C slave driver" and I did not find some tutorial. Hopefully some guys can quickly tell me how to do it. My hardware setup: custom s

Stefan, Is that IC a sensor? Do you need to use interrupt on it? I would suggest you to start taking a look at the code from the sensor https://github.com/zephyrproject-rtos/zephyr/tree/master/drivers

Merci! I took the tlv320dac310x audio codec driver as template. Done a very specific driver for the tlv320aic3204 from TI. It is not streamlined with the zephyr audio api. I can send it to you or put

Hej ho I like to do polish my stuff before I push it and for that I am asking for your help. So far I created a driver for an audio codec. This codec is controlled via I2C. Setting up like a common dr

Hello, I'm working on manipulate data in a sdhc disk. My problem is that I can't unmount the disk. When I call the fs_unmount(structfs_mount_t *mp) function I got this error "fs ops functions not set!

Lucas, You're right, the unmount operation isn't implemented in the FAT fs_file_system_t struct. It should be possible to implement it easily, though. Something along the lines of: static int fatfs_un

Thanks for the answer. You are right, the problem was solved implementing the fatfs_unmount function that you said. I made some tests and everything is ok. On the weekend I will create a PR.

Hello, I'm using a module named Quectel GSM/GPRS M95 to connect to the internet. Until now I'm using it with UART and AT commands, but I'm wondering to use the PPP that released in v2.0.0-rc2 version.

I am attempting to write a basic I2C program using Zephyr, but I am currently unable to sent a single byte over I2C. The program hangs after the first clock falling & rising edge. I'm using external 1

After further testing, I found that if I step through each instruction with the debugger the individual messages send correctly, but not if I let the program run regularly. In neither case does the i2

Hi all, for a specific design need, I would like to fix the address of the ram_console buffer in RAM_CONSOLE driver. Which is the best way (if feasible) to set it? Thanks, Michele

#driver

It's just a character buffer. If you need to pin it to a specific memory address, I imagine you'll have to route it to a special input section that is placed where you want it in memory in the linker
