ChibiOS Free Embedded RTOS

Are you sure?

For example there (STM32F070):
http://www.st.com/web/en/resource/techn ... 141386.pdf
In all place we have USART4, not UART4.

But in:
http://www.st.com/st-web-ui/static/acti ... 191185.pdf
You have in all place UART4.

More over in stm32f070xb.h registry is named USART4, not UART4.

OK, but now there you have uart4, it should be uSart4, so when you try use that, compiller can't find registry UART4.
I see you have conflict with another STM peripheral.

More over, STM32F070 have USB, so in stm32_registry.h in line 1521 should be
#define STM32_HAS_USB TRUE
#define STM32_USB ...

Hi,

I would like use USART4 interface in my project, but how I see, actual hal not support that?
In technical description (m) on page 10 we have that STM32F070CB and STM32F070RB have 4 USART.

So what in this situation, I shoud run USART4 via direct control registry or maybe exist some other hal ...

Hi,

I try use new Chibios 3.0, but when I try run some peripheral, then I stuck in:
DMAv1/stm32_dma.c:69:40: error: 'STM32_DMA1_STREAM1_EVENT_NUMBER' undeclared here (not in a function)
It's look that ...

I tried to modify system usb-serial, but it's realy dificult.

So I solved the problem by modyfication application on PC, I check how many elements was reads, and if it's not enough, then I again read, some like that:
send_buffor[0] = cmd_GSM_nr;
usb_bulk_write( dev, EP_OUT, send_buffor, 1 ...

Comunnication look that:

At blue is first cmd do device.
As you can see, it's somethink wrong with device.

For test I do something that:
uint8_t buff[64] = {1, 2, 3, 4, 5, 6, 7, 8, 9};
if(flags & CHN_INPUT ...

Oh, I wrong copy my code, it's look exacly that:
static WORKING_AREA(waUSB, 128);
static msg_t USB_thread(void *arg)
{
(void)arg;
chRegSetThreadName("USB");

EventListener el1;
flagsmask_t flags=0;
uint8_t cmd_res[2];
uint8_t clear_buff[64], buff[64];

sduObjectInit ...

Ok, I run debuging and compile project with options:
CH_DBG_SYSTEM_STATE_CHECK
CH_DBG_ENABLE_CHECKS
CH_DBG_ENABLE_ASSERTS
CH_DBG_THREADS_PROFILING

Sorry, but I don't understand what did you mean about use usbSTOP on transmission.

I set breakopint at first sdWrite, and i think I know why it's ...

Yea, I trying write and read without timeout, but still do the same.

In system exist only 2 threads, one with only chThdSleepMilliseconds(650) in while loop, and secound with this USB, so system most of the time do nothing.

Ok, i found what is wrong,

EndPoint 1 it's must 0x01 value, 0x81 it's needed only in configuration_descriptor.
Now I can read and write data

But I have another problem... I try send answer for incoming command:
while(TRUE){
chThdSleepMilliseconds(1);
if(SDU1.iqueue.q_counter ...
