Re: Porting to STM32L151

Something I fatefully did not notice was that there is no onboard 32768 clock on the BlueNRG development kit. Real time clock could not start, buggering up everything.

Thanks

Re: Porting to STM32L151

Sorry Giovanni,
I'm kind of new to this.

I'm trying to execute the STM32L152RET6 nucleo demo on the STM32L151RBT6 using gcc, but nothing is executing and the led blinking thread never starts. I realize what I just throughout was an error was just undefined command because it will be inserted at run ...

Porting to STM32L151

Hey,
Right now I've just received the blueNRG eval board, and i'm working on changing the demo code they've provided over to chibios underpinnings. I think I'm going to leave the BT stack alone and just make change the low level interface and timing from chibios functions.

I was wondering how to ...

Creating a BaseSequentialStream out of a Buffer

Hey Giovanni
What are the steps I would need to make the shell write and read from a buffer instead of the serial port?

I've tried to examine the inheritance scheme, but I'm still at a loss for how to go about implementing it. It looks like I could create something based on memory streams, but to ...

Re: shellExit() Where to call from

shellExit() Where to call from

BaseSequentialStream(quickie)

Quick question, I'm writing code targeting the stmf0's Uart right now. can a base sequential stream be SPI based? (Can the shell target SPI peripheral?)

Thanks
