STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on October 02, 2014 at 16:28 Hi, I have a major problem about mySTM32F I'm trying to join usage ofPWR_EnterSTOPMode with USART. I use USART1 and 3 from my microcontroller, it initialiaze properly and I'm able to communicate through it. Me...
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 September 28, 2014 at 16:18i use the cube to generate ltdc ip code of stm32f429，why i can't get the base graphic function such as LCD_DrawLine ,LCD_DrawCircle etc？must i write the function by myself or copy the functions from ''the stm32f...
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...
