ChibiOS Free Embedded RTOS

Thanks, Giovanni. I wanted to make it so you would feel free to (eventually) distribute it in the ext/ directory at some point in the future. I was too lazy to search around and see how others had licensed their work.

I'll revisit it.

Next up: LEDComm-UART driver.

I've created a library for ChibiOS called LEDComm.

It allows you to use a single LED for slow (around 30 baud), very short range wireless (less than an inch), bidirectional asynchronous serial communications. The signalling allows for half-duplex operation, 7- or 8-bits per character (transferred ...

Well, this is embarrassing!

It turns out that the LED on the current-limiting resistor on the cathode instead of the anode. This, I assume, prevented the proper charging of the parasitic capacitance.

Once I changed things around, all is working well now! Sorry for the fire alarm and thanks for the ...

All the output modes are set using the statement:
palSetPadMode(led->cathode_port, led->cathode_pad, PAL_MODE_OUTPUT_PUSHPULL | PAL_STM32_OSPEED_LOWEST);


PAL_STM32_OSPEED_LOWEST is defined in GPIOv2. I think that's valid for both boards (I see GPIOv2 referenced in both ChibiOS-RT/os/hal ...

I found that the interrupt is getting called (I verified it in the debugger).

Here's what's odd. Take a look at the logic analyzer display:

The range between the green markers (at around +8.5 ms) shows the ...

ChibiOS-RT: Git branch stable_2.6.x
Platform: STM32
Board: ST_NUCLEO_F401RE

I'm writing code to drive an LED for bidirectional, short range (<25 mm)
wireless communications (see m). My
hope is to eventually provide a (slow) Serial and UART driver to the community.

I have a prototype version ...

I recompiled an application currently working on a NUCLEO-L152RE board to work on a NUCLEO-F401RE board (with appropriate changes to the Makefile, mcuconf.h, etc.) and got the following compile-time error:

Works with openocd too. Here's a snippet from my session:

Hi,

Support for that board is the repository under the 2.6.x branch, including an untested demo.

Well, consider the demo tested! I cheated and copied the binary to the USB file system (I'll try openocd next).

I'll give the 2.6 branch a try then. Thanks.

Here's my openocd version and configuration file -- again, take the configuration with a grain of salt with me being a newbee but I was able to issue a "monitor load ..." command and it appeared to work.
