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. ...
Posted on July 10, 2013 at 23:04I'm working on getting the ADC fully integrated with the rest of my code. When I'm testing out my ADC, however, I keep getting an output of about 300-400 from ADC1->DR when I'm inputting a voltage of 0 to the pin. I...
Posted on July 02, 2013 at 06:08i have a problem with recieve data to stm32. send data to UART works fine in hyperterminal on windows i see all wordl who send stm32. But we need to STM32 could also receive data from the computer.I need to able to re...
Posted on July 12, 2013 at 09:46Hi all,I am working USART RX interrupt.I am sending command through rs485 interface (usart TX) and waiting(delay) response from external device.What i wonder is , there is a flag for waiting last received data?i dont ...
