ChibiOS Free Embedded RTOS

All code working now in all the UART devices. Checked several times, as it is usual, some pin confusion.

This events information is very usefull but it was really a pain to find it, it would be nice to have an example like this documented somewhere else, but for the mean time this will do.

Thanks

Hello Giovany and other forum members

Today I come here because I used event for SERIAL Driver input a long time and now with the new functions I was testing its functionality as seen in this post: http://forum.chibios.org/phpbb/viewtopic.php?f=2&t=872 .

This method is working fine ...

Hi everyone!! Sorry for the late answer.

Giovanni: My CPU doesn't get stuck anywhere, the execution is run normally.
barthess: The function successfully returns and status==RDY_OK and errors==0. Indeed it returns 0, but instead other data should be returned. Is weird that the eagletree page is ...

Greetings

With a little shame I come here asking for assistance. I was trying to read Altimeter V3 and Airspeed V3[1] sensors from Eagletree, which have a I2C bus to acquire its raw data. Eagletree provides information on how to use this sensors, the I2C addresses and pseudocode to access it[2 ...

Thank you for all the help.

It was indeed a DMA channels problem, I updated my trunk, changed I2C1 DMA channel and problem solved. Once I fixed it, I tried reading and writing to a BaseChannel in a SerialDrive, but for a high amount of iterations, it seems to create a system lock, so UART driver ...

Ok, found the posible DMA ids in the hal_lld.h file, but when changing STM32_I2C1_TX_DMA_MSK from (STM32_DMA_STREAM_ID_MSK(1, 6)) to STM32_DMA_STREAM_ID_MSK(1, 7)), the system stops working (I tried this in the discovery F4 demo).

Could this be a DMA related issue? the debugging hasn't been ...

Thank you again.

But trying to fix this in the mcuconf.h file, an error occurred:

../../os/hal/platforms/STM32/uart_lld.h:239:2: error: #error "invalid DMA stream associated to USART2 TX"


Does this mean I have to change the DMA stream definition in both ...

Giovanny, as always thank you.

A little explanation about the DMA channels please, what part of the configuration shows this?

This is my mcuconf.h file:

I enabled all the debugging options in this page: http://www.chibios.org/dokuwiki/doku.php?id=chibios:guides:debug_guide
In compilation time, no errors occurred.

I will try and use st-link and gdb to debugg. Do you recommend me using eclipse for this?

Greetings, I am using various available serial protocols in stm32f4 discovery board. I am using the USART driver and Serial Driver.

When I use SD4 in pins PINA1 and PINA0 with USART3 in pins PINB10 and PINB11, everything works fine, but when I add Serial Port 2 (with Serial Driver or USART driver ...
