Posted on April 14, 2016 at 15:56Hi guys,I am new to embedded word.I just started working with STM32vl discovery board using Keil uvision(MDK-ARM).I am not getting any example project for testing USART on board till now.Can any one provides me that...
Posted on October 01, 2015 at 14:14I've STM32f417IF. I try to user RTC. All Init code writed by STMCubeMX. Then i set date and time, but after reset RTC time clean again.RTC have own big capasitor and i just make reset, without poweroff.What is wron...

Posted on April 13, 2015 at 23:22I'm working on a very space-constrained design for an STM32F405RGT6 that needs 48MHz for USB FS. Ideally the crystal is a 3.2mm x 2.5mm footprint. Availability suggests that 12MHz is a perfect HSE for my needs. I'...
Posted on April 13, 2016 at 12:37Hi,I am using a STM32F429I discovery board. I have a running project in which I can generate code from STM32CubeMX. I would like to disable ''16-bit byte'', because I need the pin PE0 as a clock source for TIM4 (ETR2...
Posted on April 14, 2016 at 12:42Hi allAssume that I have SDRAM 13rowx10col is connected to stm32f7. I need to know the order of rows in conjunction with banks. Is physical address is calculated as follows: A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 ...
Posted on March 22, 2016 at 16:58Rev 3 of the User Manual shows Pin 9 of CN14 to be PB7 (USART RX) in both Figure 3 and the schematic (Page77); in Table 33 it shows CN14.9 as PC3. Where does PB7 come out to a header if at all? My USART_RX signal on...
