In the cp210x_gpio_example.c code on your website I do see the ioctl() code. The only dependencies that example has are iostream, fcntl, stropts and termios which I believe are not dependent on your driver, is that correct? Maybe I misunderstood your first question; I was using the d...
Thank you for the code. I've done everything like the video, but there is some errors in this file "lcd_io_gpio16.c". For example, in line 73 (#define GPIOX_SET_(a, b) GPIO ## a ->BSRR = 1 << b), there is this error: 'GPIOX' undeclared (...
OK, thanks for the info. I see how this works on the '123x devices but the GPIOHBCTL register is no where to be found in the TM4C1294NCPDT data sheet. All of the example projects for the '129x in TivaWare still use the APB to access the ports. ...

So, for cp210x.c on kernel.org, it was limited to serial only, and we provide an example on our website of how a person might do it if they wanted to compile their own driver. Of course, that's a memory of a conversation from a few years ago - I'm not sure if things have...
The GPIO Driver enables the GPIO controllers available on the device. The driver configures the GPIO hardware and interfaces and makes them available to the sysfs interface for user space interaction or other device drivers that need to access pins. For example, a MMC/SD driver may need to rea...
2) I'm not sure there is any handler at all for the StarterKit. For the GP EVM, for example, there is the matrix keypad driver that gets registered and provides an ISR for the button interrupts. You can check the driver inside<linux>/drivers/input/keyboard/matrix_keypad.c. ...
