ChibiOS Free Embedded RTOS

I control my 3D printer with Chibios.

I use a STM32F417 and can print high resolution g-code files from the SD-card without problems.
The max. steprate is around above 100kHz. (Never tested it to the limit)

An CNC should be no problem.

I have the STM32 host stack running under ChibiOS 3.

I used this project as a starting point:
https://github.com/ErikZalm/uubt

It is a 3D printer controller.

This is a board I designed.
It is running ChibiOS 3.0

Hello Giovanni,

What are the needed changes for switch ChibiOS 2.6 to 3.0.

Hello,

I also have a board with the KSZ8051RNL.
I use a external 50MHz osc. and have init the phy.

I made the following changes:

board.h

/*
* Ethernet PHY type.
*/
#define MII_KSZ8051RNL_ID 0x00221550
#define BOARD_PHY_ID MII_KSZ8051RNL_ID
#define BOARD_PHY_RMII


mcuconf.h

#define ...

Thanks,

It works ok now.

Hello Giovanni,

I found 2 problems with the driver.
1. On OSX and a vmware virtual machine the enumeration fails. The address needs to be reset to 0 in usb_lld_reset().
( OTG->DCFG = (OTG->DCFG & ~DCFG_DAD_MASK) | DCFG_DAD(0); )

2. When I use termite as terminal program (In windows XP) the ...

Hello Giovanni,

Thanks for working on the USB driver.

I can make USB traces with an ellisys analyzer.

Do you want cvs traces or ellisys native format. You can download the software to view it from ellisys.

Hello Giovanni,

Can you give an update on the STM32F4 USB status?

Do you have a todo list and development branch so we can help implementing and testing the driver?
