ChibiOS Free Embedded RTOS

The firmware is implemented as a composite USB-device with diferent configurations, and in some configurations we use the CDC serial driver. But the active configuration we are talking about doesn't use Serial_USB driver, just HID sensors. Using wireshark to check the traffic through the USB, we can...

Hello forum. My uC is connected to a Linux kernel through a USB interface. It is running Chibios 16.1.0 firmware to send data collected from HID sensors to the Linux kernel. Running on a Linux kernel 4.x, the application can receive data through Industrial I/O subsystem (IIO) and consume them. That ...

Thanks a lot for your advice, that's a good point. I didn't fall into that detail but you are right, that could be the problem. I have checked it now: The main Makefile of my project includes this line: # Compiler options here. ifeq ($(USE_OPT),) USE_OPT = -O0 -ggdb -fomit-frame-pointer -falign-func...

Hi all. The openocd setup file attached previosly has this line: transport select swd I assumed that option enables SWD as expected, but probably I am missing something else, the setup of that tool is more complex than expected (>_<), I just wanted to check the content of a variable [...] I have tes...

I have a j-link EDU SEGGER J-TAG available, and would like to use it to debug a Chibios application developed using a STM32F072B microcontroller. Packages openocd and arm-none-eabi-gdb are properly installed in my Ubuntu development host. The content of myboard.conf openocd configuration file is thi...

First of all, thank you for your fast and valuable feedback. What should be the most convenient way to manage that inside ISR context? Defining a callback for the fourth usbSetupTransfer parameter (currently set as NULL)? Or publishing an event inside ISR and managing it in the main loop? CH_DBG_SYS...

Thanks for your fast answer :) This is the whole code of my setLineCoding function: void setLineCoding(cdc_linecoding_t* lcp) { SD1_cfg.speed = (uint32_t)lcp->dwDTERate; // DEBUG if (SD1_cfg.speed == 115200) { led_on(LED_A); } if (SD1.state != SD_UNINIT) return; while(SD1.state != SD_READY) chThdSle...

I have a problem setting up the baudrate of my USB CDC serial port. This is my initial SerialDriver configuration: // 9600, 8N1 SerialConfig SD1_cfg = { 9600, 0, USART_CR2_STOP1_BITS, 0 }; The SerialDriver is initialized in this way: sdObjectInit(&SD1, NULL, NULL); sdStart(&SD1, &SD1_cfg...

I come back with my initial issue, providing all internal details for a better understanding. My USB-device is composed of three different functional blocks: * HID sensors * HID inputs * CDC ttyACM The inputs and ttyACM pins are shared. The purpose is developing a Chibios driver to separate all the ...

Continuing with this issue, I have another question related. On the usb_event_cb callback (first callback defined on the USBConfig variable), when the USB_EVENT_CONFIGURED event is handled, the endpoints specified in the configuration must be enabled. But I my particular case, I have two configurati...
