Posted on October 18, 2011 at 03:34The data sheet for the STM32F4 series states that 24 external ADC input channels are available, but I can find only 23 in the pin assignments. ADC3_IN8 appears to be missing. The F4 reference manual (RM0090) descri...
Posted on October 17, 2011 at 18:59Hi guys,I am trying to retarget scanf for USART1 of STM32 using Atollic. I think the utilized toolchain makes use of _read_r for the scanf (please verify if possible). So I need a new definition of _read_r. Any ide...
Posted on October 17, 2011 at 17:06Hi all, I noticed that arm-elf-gcc, arm-elf-binutils and arm-elf-newlib are included as pre-built packages with Cygwinports. ftp://sourceware.org/pub/cygwinports/portslist.txt Can this tool-chain be used for STM32...
Posted on October 07, 2011 at 10:52Hi, I am desperately trying to get the FreeRTOS MPU port running on my STM3210e-Eval Board. (Yes I am sure that my MCU has the MPU ;) ). I cannot find a working linkerscript for the GCC Toolchain. Has anyone ever...
Posted on October 17, 2011 at 17:52I have been looking at the USB OTG Libraries for the 105/7 and I've come across the variable TotalFifoSize. It's set to 320, when using the Full speed core.I was wondering if anyone knew if this was because of a ...

Posted on September 30, 2011 at 20:39Hi all,does anyone know if STM32 family I2C master supports 24-bit device ID reading from an I2C slave? I have a slave compliant to I2C rev 03 standard and I need to read it's device ID. Please help, have you any...
Posted on October 13, 2011 at 17:15Hello,We are trying to send a 44 byte report over SPI from one STM32F103 to another board. Our master sends this data out every 5ms, and our slave receives data based on an interrupt. We are experiencing an issue ...
Posted on October 12, 2011 at 10:48Hi, I need to reset individual bits in already written word/byte in the on-chip flash (from 0x0800 0000). The problem is that according to Programming manual PM0075 (STM32F10xxx Flash memory microcontrollers) : Fla...
