ChibiOS Free Embedded RTOS

I consider the situation reasonably safe. Suppose the bootloader would randomize the whole memory. In that case, there would be a 2^-32 chance this would happen: 1 in 4 billion. I can take that risk. But the bootloader will only use 1 of 20kbyte of RAM in my CPU. So actually we're looking at 1:80 bi...

i will test it, if I set CAN_ENFORCE_USE_CALLBACKS TRUE, can i have faster speed? If what you want is to really print the incoming packets, you have to first do the math: Is that theoretically possible. To me it looks as if you are running out of time to print the packet summary with the first pack...

Hi, I used the flag-at-a-constant address method at first too. However, after a while I changed to simply using a variable. Now normally a global variable starts out as "zero", but that doesn't happen by accident: There is code to clear all global variables just AFTER the "early_board...

You don't need to stop, just call sdStart() again to set new parameters, of course you need multiple configuration structures. i This is inconsistent with lots of other stuff in Chibios: Many things in Chibios don't tolerate being restarted by "just call start again", because they are not...

OK! How do I instruct "chprintf" to do that?

I have several applications where my application on the STM32 provides an USB_CDC commandline interface to the user. So during development I have a terminal program to type commands and see responses. But then for "internal applications" I might want to automate something through the modul...

For posterity.... Even with slow SPI speed, the long cables can be a problem. The SD cards are too small to house an on-card decoupling capacitor. So that should be just outside the card connector. So with these long wires, the SD card may suddenly draw too much power that the non-existant "clo...

I got the nucleo32. It doesn't have the "target-USB" connector that I thought it had.

OK. I downloaded the stupid thing. Then I get a welcome screen with a "readme" link. CLick there. Download more and... screen is VERY complicated but no "readme" info. new chibios project? new menu entry gives me "java project" and "enum" as options. Where is ...

You need to make a "BLDC motor controller". This is FAR from trivial. You can look at VESC (also uses CHIBIOS) for example code.
