Posted on September 28, 2014 at 20:37I've been trying to get my st discovery board to receive data from my computer over the USB. My source is attached. I've been working on this for a long time. The progress is slow. I spent weeks just to figur...
Posted on October 07, 2014 at 13:37Hi list, page 932 of the reference manual gives a formula to calculate USARTDIV. But if I check the first entry in table 133 I get completely different values. With Pclk=8MHz I get 8.10^6/(16*1200)=14.7, while the ...
Posted on September 25, 2014 at 22:36Hi all, After reading the RCC_CSR register to determine the reset source, I want to clear the register so as to be able to resolve future non-por resets. When I follow the instructions in the datasheet, the bits...
Posted on March 30, 2013 at 23:59So I am having an interesting issue with configuring the ADC to work with anything but PortA. I can hook it to any pin on port A, change the ADC channel, and it will work. However, I have tried doing the same on Po...
Posted on October 04, 2014 at 19:08They are aliases of channels 15,17,17,17 for ADC 1-4 correspondingly. According to STM32F303VC reference they should by aliases of channels 3,3,1,3. Firmware works correctly only when they are set according to refe...
Posted on October 01, 2014 at 19:53 Hello, I am trying to use an STM32f4 discovery board to receive data in slave mode over SPI. I am using HAL drivers generated from STMCube and using interrupts to receive the data. I can read all the d...
Posted on October 07, 2014 at 16:28I am using an STM32F407xx.My setup is that I have TIMa triggering TIMb. Here is a description of the behavior that I want:TIMa:Don't care. This part looks to be working in my application.TIMb: When we get a Trig:...
Posted on December 17, 2013 at 22:25We need (don't ask why) to use a PHY which does not have COL, CRS or RX_ER pins. Can these be tied off to appropriate logic levels on the STM32F407xx we're going to be using and still result in proper operation?T...
Posted on October 07, 2014 at 11:01Hi all, it's supported freertos 8 in the latest CUBE MX software(version 4.3.1) ? Thanks!
