Posted on July 15, 2013 at 05:29Hi, Did I get it right that during Sector Erase (that can take up to 2s on 128K Secotor) CPU Core does not fetch instructions from Flash memory? In other words Bootloader running from Flash will be halted during this ...
Posted on January 21, 2013 at 19:48I have a STM32-F4 discovery board, specific model ♯ STM32F407 VGT6. Having connected it to my computer via USB I have successfully run its test programs. Additionally I have successfully built a test program that c...
Posted on April 10, 2013 at 15:44 Hello, I'm using a STM32F4DISCOVERY to program the firmware of my future board. I want to use the integrated 12 bit DAC of the board to generate analog simple signals on the A4 and A5 pins, but I don't wa...
Posted on July 12, 2013 at 00:17Hi, I'd like to have algorithm executing application (from 0x8004000) operating on data buffered in my modified IAP firmware (2 x (uint16_t [128]) located after IAP code, before 0x8004000). But after compiling my IAP ...
Posted on July 14, 2013 at 15:10dear all, I hope this finds you well. I am relatively new to such technology and I am working on some drivers. The board I am using has 4 LEDs, a joystick and a couple of buttons (WAKEUP and USER). I have implemente...
Posted on July 11, 2013 at 15:19 Hello, is F4 Flash write can be random or only sequential? I've tryed to do FLASH_Unlock(); FLASH_EraseSector(FLASH_Sector_8, VoltageRange_3); for(i=0, EEAddr=EEA;i<32;i++){ FLASH_ProgramWo...

Posted on July 13, 2013 at 08:46I ported the printf functions to UART3. I am reading some gyro data from a digital chip that gives it's results in 2's compliment. So I get the raw data and print the integer that I stored it in. But the printf functi...

Posted on June 13, 2013 at 09:18Hi, I've configured ADC1 to sample one of the channels like PA1 (Channel 2). However, when I connect a power supply to the input, there is a large offset. For example, connecting 2V I can see around 200-250mV offset. ...
