Re: Lineendings in the git repository

Just take careful consideration before you enact a change to line endings in the repository. I.e. be careful, you don't want to go back. You will generally have to commit a change touching all text files in the repo, or at least those that don't have the "canonical" line ending yet. This w...

Re: lwip + webserver in simulator

You could also set up a bridged virtual network interface in Linux. For instance, VirtualBox allows you to choose "bridged" instead of "NAT" for the guest OS networking, and if you choose bridged, the guest machine gets a real MAC address that will appear on the host's LAN. Look ...

Re: RTC driver for Kinetis.

Hmmm, DST changes at between 2AM and 3AM in the US. Some nights have 2 x 2:30AM, some nights have none. Alarms which span DST changes would be tricky. Absolutely that is a huge concern. DST makes things ugly. I have always wondered if the DST time change "repeated hour" or 2AM-3AM could p...

Couldn't you typedef an alias like

Code: Select all

typedef MailboxBuffer<1> Mailbox;
or something?

Re: RTC driver for Kinetis.

Awesome progress Derek. Will this support a 32.768 kHz crystal on the FRDM-KL25Z board? I replaced the stock 8 MHz crystal with a 32.768 kHz crystal on about half my FRDM-KL25Z boards, so I can use the FLL for the system clock (faster wakeup and lower power consumption than using 8 MHz+PLL, also you...

Re: SPI2 with FatFS stuck waiting

Could there be a DMA channel conflict with the SPI2 TX, RX DMA channels?

FRDM-K64F board (MK64FN1M0VLL12 MCU)

I'm thinking about trying to port ChibiOS/RT to the FRDM-K64F board . This board is awesome since for 29.00 USD (in stock at Mouser) you get a Freedom board with ⋅ 32-bit ARM Cortex-M4F core running at 120 MHz ⋅  1MB FLASH ⋅  256KB RAM ⋅ LQFP-100 package &sdot...

Re: Kinetis EXT handler channel mapping

Deal - using the temp var is fine and I agree more readable than my suggestion. Thanks.

Re: Kinetis EXT handler channel mapping

Cool. One suggestion: How about instead of two read-modify-write operations as the patch does with + /* Clear the IRQC bits */ + port->PCR[pin] &= ~PORTx_PCRn_IRQC_MASK; + /* Set the IRQC bits */ + port->PCR[pin] |= PORTx_PCRn_IRQC(irqc); +} what about something like + /* Configure the IRQC bits...

Re: I2C Slave mode support?

OK, I agree that the transaction size restrictions of this multi-master I2C driver are a reasonable compromise for simple use. If special capability is required then users will just have to write a low level I2C driver customized for that purpose. It's determined by the size_t type, which was define...
