Posted on May 16, 2012 at 23:26Hello I have a problem with calculating internal temperature with STM32. When processor VCC is 3.3V everything is ok - temperature is almoast accurate with wide temerature range. But whet processor VCC is below 3V temp...
Posted on May 16, 2012 at 06:43Dear all, I'm using `Keil uVision` with gcc toolchain (Sourcery Codebench lite for ARM EABI) to program the `STM32F4 cortex M4` chip. The compiler control strings I have set are: -march=armv7e-m -mfpu=fpv4-sp-d16 ...

Posted on May 16, 2012 at 15:12Hello, The Cortex M3 have the �ID Unique device ID register (96 bits) �, this number give to the user application technical information about the Cortex M3 mounted in the PCB ?. Extract from the datasheet RM008 revisi...
Posted on May 13, 2012 at 07:30Recently found a problem when test the F4 USB: I use the F4 Discovery chip version of 'A', the manual says this version , there are some bugs in USB. the Lib 2.1.0 ST OTG consider these bugs?
Posted on May 15, 2012 at 08:47Hi all, Now, I'm trying to implement nand driver of SAMSUNG K9K8G08U0D (SLC, 1GBYTE) on STM32F205ZG cpu. However, it not easy to do it. First, reading device ID is OK. Second, block erase function is also OK. But,...
Posted on May 15, 2012 at 19:31I wonder if someone could help me. I need to save, to retain ''some'' variables of my applications, but the 4Kbytes from the Backup registers is too few for what I need. So I would like to ask if there is another way t...
Posted on April 10, 2012 at 11:25Hello, we are using the microcontroller STM32F100C6T7 in our design. While trying to do something with the internal temperature sensor we noticed that the slope we measured doesn't correspond with the specified slope...
