ChibiOS Free Embedded RTOS

I confirm USB CDC + Mass Storage with native ChibiOS support will be a must have.

Just for information I'm using TokenLine with chibios (in my project hydrafw) see https://github.com/biot/tokenline
I think it is the most powerful shell with completion and tons of very good feature for compact code and fast advanced shell management.

I have done some test changing => #define SERIAL_USB_BUFFERS_NUMBER 2 to 4 or even 8 but I have not seen any speed increase for short packet < 1000 bytes. I have used this python script: https://gist.github.com/bvernoux/09cf99b9e487409bfa3bb76715fb65bf I suspect bad performance on packet < 1000 byte...

I have done a benchmark with different options for USB CDC PC TX and Chibios RX: The new driver is very good (versus old chibios 3 driver) only for packet >= 1000 bytes (which reach about 850KB/s with USB 2.0 FS on STM32F405@168MHz) It is strange but during test with my PC at different time (probabl...

The most interesting support will be for LPC4370 as it is the best and cheapest MCU !
For information I'm the main developer of the firmware for AirSpy which use it with open source code here https://github.com/airspy/firmware
And If someone plan a port I could help.

Hi, It is just an announce about my new project, HydraFW is a native C (and asm) open source firmware for HydraBus board with support of HydraNFC Shield. Of course my project is fully open source and use ChibiOS 3.0 running on a CortexM4@168MHz (STM32F405) This version is basic and mainly for HydraN...
