Hi,
I use a STM32F4DISCOVERY, and I would like to begin to understant how the USB HOST/OTG works... ands it's not easy, there is a lot of files and lines of code.
I saw in ST examples, that in s...
Posted on November 23, 2012 at 23:08Hi,Does exist any serial library for STM32 ? I searched on this forum and google and I found nothing, I'm looking for a traditional serial lib that allows to send other types of data than char (int32_t, float ...)...

Hey everyone,
I'm working on the STM32F4DISCOVERY with CoIDE 1.6.0 in C++. I have an interrupt on TIMER4 overflow, and so I put the interrupt service routine (void TIM4_IRQHandler(void) {}) in the main.cpp....
Posted on March 03, 2013 at 19:21Thank you for your answer. It's the V2.0.0 of the USB OTG/HOST libraries.For instance the ''Audio_playback_and_record'' example from the set of 22 examples dedicated to the STM32F4DISCOVERY (http://www.st.com/web/en/...
Posted on November 29, 2012 at 13:07As promised I put my lib on github. It's a very simple way to use the UARTs of the STM32F4 (transmission/reception). Feel free to make any comments and to report bugs :)https://github.com/Absurdev/UART_STM32F4
Posted on November 27, 2012 at 21:29Ok now I understand better what you mean, thank you. I use CoIDE and indeed there is a way to retarget printf to an UART. Unfortunately it doesn't look very convenient if I use several UART for example, isn't it ?...
Posted on November 25, 2012 at 21:38Heu... I have got an STM32F4DISCOVERY, the only possibilities for the time being are to get and put one byte, that's why I was asking if some lib exists to allow more ''high level'' functions. Otherwise I'll imple...
Posted on November 23, 2012 at 22:37Thanks for you (technical) answers. I learned things, mainly about mangling.By the way, I found a very simple way to solve it : put the definition of the IRQ_Handler in a .h and put the extern ''C'' around here (a...
