ChibiOS Free Embedded RTOS

Create two new files key.c and key.h and add them to my project.
step1: defined a global variable in key.c： uint8_t PHOTO_COUNT = 0;
step2: extern it in key.h:extern uint8_t PHOTO_COUNT;
step3:add #include "key.h" in key.c and main.c
step4: add key.c in makefile.

# C sources that can be compiled ...

the configure of my project is as follows,after compiling,i find error：#error invalid DMA stream associated to ADC2
/*
* ADC driver system settings.
*/
#define STM32_ADC_DUAL_MODE FALSE
#define STM32_ADC_COMPACT_SAMPLES FALSE
#define STM32_ADC_USE_ADC1 TRUE

there is the following description in icu.h
/**

* @details The cycle width is defined as number of ticks between a start

Hi Giovanni,
I'm working with ChibiOS 2.6.7 on STM32F103RCT6, can i use CAN and USB in one project(not at the same time)?
when i do this , i find these errors:
2.6.7/hal/platforms/STM32/USBv1/usb_lld.c:280: multiple definition of `Vector8C'
2.6.7/hal/platforms/STM32/USBv1/usb_lld.c:291: multiple ...

Hi everybody:
SD1 can send data to serial debugging assistant，but cant received the data send from serial debugging assistant. Here is the code i am running:

static WORKING_AREA(waCANThread,4096);
static msg_t CANThread(void *arg)
{
(void)arg;

// EventListener el;
BaseChannel *seri=(BaseChannel ...

my device is stm32f103, and i have find the problem is the GPIO has not been correctly programmed, thank you for your reply,have a nice day
Hi everybody:
There is no questions of my hardware，i have tested it with standard CAN transmit program. But on the chibios system，i cant detect any signal on ...

thank you for your reply, I have find the problem is the GPIO has not been correctly programmed

If the loopback demo works then there are several possible causes:

1) The loopback has not been removed from configuration (not your case).
2) The GPIO has not been correctly programmed (alternate not ...

Hi,

It is probably an issue with GPIO alternate setup, make sure that CAN functions are only programmed on a single pin. There are also CAN examples under /testhal, try running one of those first.

I have tested using CAN examples of you adviced, It can receiving data in silent mode and ...

thank you for your advice,i will try it and ask you later if have other problems

Hi everybody:
There is no questions of my hardware，i have tested it with standard CAN transmit program. But on the chibios system，i cant detect any signal on the TX pin of the hardware.I think the CAN configurations of my program are correct, so, what is the reason caused the CAN transmit failure ...
