Posted on April 18, 2012 at 05:10Hello I had a hardware design question on the usage of the USB DFU bootloader on the STM32F4 microcontroller. In ST's AN2606 bootloader appnote it says: ''If DFU (USB FS Device) is used to connect to the bootloader: ...
Posted on April 11, 2012 at 18:39I wonder if someone could help me. I recently have developed my own PCB board. I've soldered all the components, and now I want to starting downloading some firmware to the uC (STM32F407ZG - LQFP144pin). For my surpr...
Posted on April 16, 2012 at 09:07In TRM STM32F4 (RM0090) it says in Chapter 4 ''PWR'', 4.1.2 ''Battery...'': Note ''Due to the fact that the switch only sinks a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 are restricted: only one...

Posted on April 15, 2012 at 14:51I am using the STM32F4 discovery board to generate a PWM signal using TIMER 1, channel 1, and am using GPIO A8 in AF mode. When i run the code there is no pulse generated, but the pin A8 gets pulled up to Vcc. The a...
Posted on April 12, 2012 at 17:18Hi,I have written a Bootloader that looks at the micro sd card and loads firmware.bin file into address 0x00800C000 and jumps program execution to 0x00800C004. I have changed the Flash address in the code that is loa...
Posted on April 10, 2012 at 22:18While it is clear how to configure the ADC sample time, the documentation doesn't provide insight into why one might prefer 239.5 cycles over 13.5 cycles, or the impact of selecting 7.5 cycles (I'm guessing 6 bits of...
