Re: [DEV] RP2040 support
About... this would be the first subsystem in ChibiOS HAL that utilizes the PIO units ...causes me a doubt... could I use a “non chibios driver” ??? I thought I was restricted to use/modify chibios code. ...because QMK uses PIO for controlling RGB leds so (see https://docs.qmk.fm/#/ws2812_driver?id...

Re: [DEV] RP2040 support
Be aware that the RP2040 doesn't have I2S support in hardware. To implement I2S the most common way is to use a PIO unit and program it to implement I2S the way you need it. As far as I'm aware this would be the first subsystem in ChibiOS HAL that utilizes the PIO units. So I think you'd need some H...

Re: [DEV] RP2040 support
The Raspberry Pi foundation released the pico-sdk 1.3.0 version some time ago. Updating the pico-sdk in ChibiOS worked without issues, I just had to update the files in the "ext" directory and the version file in "/os/various/pico_bindings/dumb/include/pico/version.h". In the rel...

Re: [NEWS] Stellar E automotive MCUs
These MCUs are just being announced now. When will you be able to buy a reel or tray of them from a regular distributor? Recently ST declared that their fabs for STM32 are fully booked out until 2025 and new orders will only be shipped after that. This is the situation for MCUs that were in producti...

Re: [DEV] RP2040 support
Just to keep the RP2040 related posts in this thread:
I have created patches to build the stage2 bootloader into ChibiOS. This allows to boot from flash.
I posted the patches here.

RP2040 stage2 bootloader / allow booting from flash
Hi, the port for the RP2040 is currently not nice to use, because you can't boot from flash, but have to upload the code with a SWD debugger into RAM on each boot. To boot from flash, the RP2040 requires a short bootloader at the beginning of the flash (stage2). This bootloader is included in the Pi...

Re: USB serial disconnects F4 every 15 minutes exactly, H7 every 20 seconds exactly.
I would try to find out if it has to do something with the actual hardware of the laptop or with the windows drivers for it. To do that I would run Linux on the laptop and see if the communication there works or is also aborted after some time. I suggest SystemRescue for this as you can run it from ...

Re: vl53l0x.c ??
I don't know if there is still interest in this. I'm currently working with a VL53L0. The official api provided by ST, while you can get it to work... let's just say that their expertise lies in hardware and not software... But there is a quite nice complete reimplementation for Arduino available fr...

Re: [POLL] Which collaboration tools should we use?
I would prefer to use something with a completely open protocol and open source server & client implementations. This would not necessarily mean that ChibiOS needs to self host this right now. I have no problem with using some service provider for it. But the option of moving to a totally self h...
