I've thrown together a quick patch for review

Please treat as a general idea, as I wasn't near a computer with an ARM toolchain and couldn't do a sanity test compile.

Thanks Giovanni, will do In case anyone else finds this thread in the future and sees the above config, it was also necessary to add OPENDRAIN as follows palSetPadMode(GPIOB, 8, PAL_MODE_ALTERNATE(4) | PAL_STM32_PUPDR_PULLUP | PAL_STM32_OTYPE_OPENDRAIN | PAL_STM32_OSPEED_HIGH); palSetPadMode(GPIOB, ...

Found my issue, I failed to start the HSI16 clock in mcuconf.h

Would it be possible to add a compile time check for this?

Forgot this, like I said I pulled it right out of the RM (although curiously CUBE gets a different answer)

Hi, I'm playing with the STM32L433-Nucleo64 board. As I mentioned in a previous thread, I'm using the STM32L443xx in my board.h since 433 isn't in the registry but shares almost everything with the 443 with the exception of missing the AES peripheral which I'm not touching. I'm using ChibiOS_18 All ...

Just wondering if anyone has played around with enabling/disabling the FPU on an STM32 on the fly. AFAICT, currently it is either initialized at boot time, or not, but once on it is on. I was just wondering if an application could feasibly turn it off when not in use, and re-enable it as required. W...

All good,

Here's a patch, it applies cleanly to trunk as well as 17.6.x and 18.2.x branches in case you want to incorporate it into them.

Hi, I've noticed at least one (SPIConfig) untagged struct. I've been toying with introducing more C++ into my pet projects, and one thing this prevents is doing C++ forward declaration. Is this done for a specific reason in Chibi, or just an oversight/nobody cared until me? Specifically the differen...

Thanks Giovanni, As it turns out, I was lazy and let google find the schematic for the L433-nucleo. What it gave me was for a different nucleo and I was stupid and didn't check it thoroughly, I just confirmed where the SPI1 bus was broken out to the Arduino expansion header. It turns out, on the L43...

Hi, I've been messing around with the STM32L433 nucleo64 board, and as mentioned in this thread: http://www.chibios.com/forum/viewtopic.php?t=4331 There is no direct support for the chip in the registry yet, but STM32L432 is a close cousin without the LCD controller. I've got a sample project up, us...
