Posted on July 05, 2013 at 12:02hello i have usb <-> R232 converter and i want to make it receive correct characters from stm32f4 board , so which capacitors i have to use with max232 to realise this ? and thnx :)
Posted on July 05, 2013 at 13:21 I am trying to use a 768kHz Xtal with 7pF load capacitors with an STM32F050C6. The problem I am having is that I cannot get the XTAL to reliably start up. I have seen it start a few times but most of the time it ...
Posted on July 03, 2013 at 11:52Can anyone suggest where I'm going wrong? I'm new to this forum and people seem to be posting longish code fragments, but I apologise if I seem to be posting an inappropriately long question. I can't get I2S comms to ...
Posted on July 04, 2013 at 11:52I am a bit confused about the F303 op amps. If they can be used in inverting mode won't a positive voltage into the minus input result in a negative output voltage? Of course it won't happen because they are rail to r...
Posted on June 29, 2013 at 13:24Is it possible to use ADC without configure GPIO for AIN? For example, if the lines below are commented in the program, can ADC still work? // GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN; // GPIO_InitSt...
Posted on June 13, 2013 at 17:16HELLO I want to upgrade the fırware of my design by usb stick , I am using the example given with the discovery board where I need a binary image of my Project myproject.BIN, I am using keil so I can generate hex f...
