ChibiOS Free Embedded RTOS

Thanks for comment,

Actually I'm not decided yet what driver to use.
I just want to quick check if my board working with SmartCard. But as usually quick maybe more than few days .

Hi all,

Just solve my problem. Very strange but after these changes I able to receive data from SmartCard:

static SerialConfig scard1_serial_cfg = {
9677, // 3.6 MHZ / 372
USART_CR1_M | USART_CR1_PCE,
USART_CR2_CLKEN | USART_CR2_STOP1P5_BITS | USART_CR2_LBCL,
0
};
..&#46 ...

ISR not executed at all.

I guess in case of wrong baud rate or parameters ISR should be triggered in any case.
Only thing that come in my mind is I/O setup. But when I'm sending something to serial port
I see that in oscilloscope, so transmission works well.
I will try to connect logic analyzer ...

Hi,

Should be 40, but I'm also tryied to wait for single byte without success.

Thanks

Hi,

Actually I'm using design from http://www.st.com/st-web-ui/static/acti ... 166510.pdf.
I'm also modified example code from ST and it's works fine.
I double checked all USART3 and GPIOC registers in both projects and they are almost the same.

Thanks.

Hi All,

I'm trying to enable SmartCard mode for SD3, everything looks fine except my application not receive any data from IO line.
In oscilloscope I see that SIM card response with ATR.

That how I initialize serial port:


/*
* Port C setup.
* Everything input with pull-up except&#58 ...

SOLVED. Problem gone after resoldering crystal.

Yes, exactly the same 8MHz crystal. Configuration I also not changed.
From Linux usb monitor I see that my board not responds at all.( As I mentioned before USB isr also not executed on board)

Yes I'm trying ./demos/ARMCM3-STM32F103.

Hi Giovanni,

Thanks for quick reply. Unfortunately I don't have Olimex board.
