Posted on September 04, 2013 at 22:45Hello everyone, I'm trying to transfer 2 bytes using SPI in master mode and DMA. Additionally I have to set and reset CS signal by software. CS signal is low before starting transfer and is high after transfer.So...
Posted on September 04, 2013 at 21:37Hi,For my project I need additional RAM, is it possible to add memory to the STM32F407VG (in the STM32F4-Discovery Board) using the FSMC interface?
Posted on September 03, 2013 at 17:15Hi, i'm working with a STM32F207VGT and i dont achieve to wake up my board from STOP mode with the RTC. The RTC is configured with the LSI because the external crystal for LSE is not mounted. I have read another ...
Posted on September 04, 2013 at 08:22My platform's MCU is STM32f205. I try to modify TIM10_PWMOutput example from STM32F2xx Standard Peripherals Firmware Library to generate one PWM signal by using TIM10_CH1function of pin PB8. But it doesn't work?...
Posted on August 19, 2013 at 13:59I may have some spurious or unhandled interrupts and want to see where and when with software catch. Is there a default (in absence of specific) IRQ handler i can overwrite / install? (E.g. as you would with HardFa...
Posted on September 03, 2013 at 14:51hello, at the moment i'm working on the DMA-USART example from the FW library to fit into my application. the transmitting process(uC=> PC) is working as estimated, but the problem is i have to update the ''DMA...
Posted on February 10, 2012 at 20:00HelloSTM32RBT6 should control 1 servo with PWM output. For all TIM2 - TIM4 I tested it seems to be OK, but for TIM1 Channel 1 which is one I need it is working only occasionally what is very strange.Sometime I jus...
Posted on September 03, 2013 at 21:50Hi everyone, I have a problem with a stm32f207 device. I use the NSS pin of the SPI2 as a GPO. (The chip select to my SPI2 devices comes from an external I2C IO expander). NSS pin (I4) seems to be working ok as ...
Posted on September 03, 2013 at 18:31Hello guys, I have a problem with DMA2, while using DMA1 in the STM32F407VGT6The thing is I�m doing a program which reproduce MP3 music while it reads the data from an SD.I use the DMA1 Stream 7 for sending data ...
Posted on September 03, 2013 at 18:27Hi,I'm using STM32F103VE. USART1(9600,n,8,1) for sending data in interrupt of TIM2.TIM2 occurs every 10ms. In TIM2 interrupt routine I call a function to transfer data via USART1: USART_SendData(USART1, x); (...
