ChibiOS Free Embedded RTOS

chnPut and chnGet are disappeared from io_channel with commit 35acf78f-673a-0410-8e92-d51de3d6d3f4, is normal?

I've never cared about USB before. Is there now any working example, which demonstrates how to use the USB driver of ChibiOS to do some stuff like USB HID or something else?
There is testhal/STM32F1xx/USB_MSC but I don't know is working. Actually I see only USB-CDC.
Maybe someone also got a linux ...

The default udev rules seem to prohibit accessing it as a normal user. but as root it worked:
sudo screen /dev/ttyACM0

the shell seemed to work.
On my linux I wrote a simple udev rule.
file /etc/udev/rules.d/99-usbdevice.rules
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0666"
So all ...

Hi Giovanni,

the usb driver, is it ready also for other applications?
For example: device usb hid (mouse or keyboard, or host usb hid attach a mouse or keyboard. device/host msd.

Thank you

EDIT
wrong word device usb not driver usb

Hi Giovanni,

thank you for your work!!!
Works, but there is a problem when I detach and attach usb cable, usb device is enumarated but read and write in serial usb doesn't work. After reset work again correctly. I'm testing in linux OS.

Also in the STM32F4 discovery, some PE pins are connected to the MEMS sensor: Precisely PE0, PE1 and PE3.

So I use PD0-PD3 to DB0-DB3 and PE4-PE15 to DB4-DB15 on the LCD.

I did not know this information. I will try with this configuration. So in STM32F4Discovery doesn't exist a GPIO with 16 Pad ...

In the lastest ChibiOS chioch.h is disappeared, so also define as chIOPut, chIOPutTimeout, chIOWriteTimeout etc... doesn't exist more.
Can I replace them with functions in io_channel.h? In this include I see same functions renamed.

Thank you

I tested and don't work very well in my environment, STM32F4Discovery + HY32D.

DeviceCode return me 0x8988 and not 0x8989, I checked many times connections on bit 0, but for device code give me 0 e not 1.
I changed the code and added 0x8988 so lcdInit setup my lcd and simple lcdClear works, but all ...

Sorry my question was very very stupid.

I don't know because my brain ignored the row readX().
Sorry for lost time.

Did you try out my library yet?
Not yet, I will try it shortly. I hope tomorrow.

Sorry I need a little information from you.
Where is "dummy readout before each "real" readout"? I can't understand.
readX or readY are simple spi operations:
- chip select
- send data
- read data

tpReadRealY or ...
