Could use some help (just starting out)

Posted on May 30, 2017 at 20:54So, a stm32 Nucleo (little sticker indicates -F411RE) was left on my desk.  I looked at tools and got System Workbench installed.  I figured a first test (of myself, the board, and the tools) would be to modify LED bli...

ART accelarator of STM32H7

Posted on October 26, 2016 at 08:45Hello experts, when compared the block diagrams of STM32F7 and STM32H7, STM32H7 seems to have no ART accelarator. Cannot software access to the internal Flash without any wait cycles? Best regards, Yasuhiko Koumoto...

Micro SD Card problem

Posted on May 31, 2017 at 18:31Hello guys,I would like to discuss with you about the problem of uSD card.Normally, it's working well if the application executes from internal Flash, but when it runs on SDRAM, the uSD can not initializes with FR_DISK...

Resolved! Wake stm32l151 up from stop mode by way of USART

Posted on May 31, 2017 at 14:56Hello everyone, I have looked up this issue but I am afraid I have been unable to find a solution. I am trying to wake a stm32l151CCT6 MCU up from stop mode by way of USART1 interrupt. I have the RXNE interrupt enabled...

USART Not Receiving Data (Polling)

Posted on May 31, 2017 at 17:06Hi guys,So I'm using an STM32F1 and am trying to send data from a serial terminal (RealTerm) to USART3 via a FTDI USB-UART converter cable. I have written code to poll for data on the RX line but for some reason my USA...

Phase-shift PWM with STM32F407

Posted on February 27, 2017 at 15:10How can I create a phase-shifted pwm signal ? The frequency is fixed. The board is STM32F407 discovery board so I am not 100% sure if this is possible.If it is, how can I achieve this?#phase-shift #stm32f4-discove...
