Posted on October 14, 2013 at 10:11I designed a bootloader and erase it to sector 0. It can erase other bin into other sectors using IAP. But how to upgrade itself to sector 0? Does anyone give me an idea? Thanks.
Posted on October 16, 2013 at 15:00Hi, I have a relay circuit which has fourteen relay output (i.e 14 devices can be switched on or off from this) , I have attached the circuit for a single output. I am sending command to switch on the related outp...
Posted on July 22, 2013 at 18:28 Hi all! I'm new in forum. I wrote this config for I2S. Instead of MCLK=256*Fs=12, 288000 MHz and CK=48KHz*32bit*2channel=3, 072000 MHz, I measured MCLK=4MHz and CK=1 MHz. My code is: ...
Posted on September 09, 2013 at 17:04Hi, I try to set a software interrupt. I set it as follows: &sharpdefine HZ500_EXT_INT_LINE EXTI_Line1 &sharpdefine HZ500_EXT_INT_IRQ EXTI1_IRQn &...
Posted on March 15, 2013 at 09:28Hello everybody, I have a question about USB device in VCP mode. I would like to keep my VCP communication open after a microcontroller reset (STM32F207). Is it possible ? In example, I have a terminal software runni...
Posted on October 16, 2013 at 01:45Hey guys,I've recently been designing a synthesizer based on the STM32F4 Discovery board. I'm using a PT8211 DAC for the audio output and an interrupt triggered at 48KHz. My audio is generated using a DDS method an...
