Re: 303 to 313 migration

ok thanks.
PS: FYI: stm32f313 requires 1.8V VDD max (good when using step-down converter), but I/Os are 1.8V too (bad) :)

303 to 313 migration

Hi, there are demos for 303 (and 373). I am planning to make a small board with 313 (a sample). My current understanding is the only diff is the min voltage (313 is from 1.8V). Provided I will copy the 303 project into my_313, what needs to be changed typically such I can compile the demo (CS5) and ...

chprintf - %ld

I cannot get chprintf print a %ld (or %LD), I am getting an int. Any hint how to print an int64_t? uxtms = 999888777666L; chprintf(chp, "%d %ld\r\n", uxt, uxtms); .. 1380670167 433985367 Interestingly, when the uxt (int32_t) increments, the uxtms (int64_t) increments as well.. 1380670542 4...

Re: DS1307 RTC I2C library

Hi Fede, enclosed your DS1307.c file with fixing some issues (do compare the files). I get none warnings with it (w/ my rtc). One Q: there is an rtc support in chibios already (os/various/chrtclib.h.c), using <time.h> library and the standard tm structure for dealing with time stuff. I like the uint...

Re: The new STM32F429Discovery

I just don't understand the usefulness of a gyroscope alone on that board.

A marketing guy did set a cost cap, I bet.. :D

A FIFO class include

I want to use the FIFO class from avr Nilrtos. I've modded it for chibi (chFIFO.h). Is there a simple way to include it into chibios C build? Do I need to build the whole stuff as cpp?

Re: The new STM32L100C Discovery kit

You may use FRAM or MRAM SPI memories, up to 512kBytes/chip today. All nonvolatile,unlimited r/w, w/ SPI clock faster than any STM can do.. :)
