Posted on February 20, 2014 at 18:00I am using a STM32F4 as a SPI slave. The STM32F4 receives a packet of data over a USART line and must have the data immediately available for use in the SPI communication. I am using a DMA Tx memory to peripheral ...
Posted on February 18, 2014 at 09:01 Hello all, I've run through couple of SPI DMA threads here, but I didn't find what I was looking for... On my STM32F103 I'm sending data to host over SPI: - my STM32 acts as SPI slave - SPI trans...
Posted on June 16, 2015 at 10:45Hi, I want to use the state of a GPIO Pin (It is driving a chip select on an SPI device) to determine that the SPI transfer has completed. I do know about the callback on the CMSIS code, but I'd prefer not to use tha...
Posted on June 15, 2015 at 13:57hej i would like to keep some file in a seperate place at flash where linker dont use it when put the code in the flash.i am using COIDE., stm32f407 discovery board.Can anyone tell me how can i do that ?thank you.
Posted on March 06, 2015 at 09:32Hi, i am very new to STM32, just installed the IAR environment. Appreciate if anyone could advise.Is there a UART example of String transfer using UART TX/RX of PA9 and PA10 in Polling mode for STM32L053 Discovery K...
Posted on June 15, 2015 at 18:43Hello,everyone. I want to capture 3 HALLs by TIM2 of STM32F051. The 3 pins are PA15,PA1 and PB10. I captured the period of HALL with PA1 and PA10 successfully, but failed with PA15. The funtion of PA15 is AF2, and the...
Posted on June 15, 2015 at 08:37Hey there,I'm having interesting times with an STM32L151 programming via a nucleo board's integrated SWD debugger (from CooCox ide..... using arm mbed platform too if that helps..) I'm in the interesting position wher...
Posted on June 16, 2015 at 03:49 (I managed to fix this as I was writing this post) STM32CubeMX 4.8.0 was generating the incorrect prescaler value for SPI3 after upgrading. .ioc contained: SPI3.BaudRatePrescaler=SPI_BAUD...
