Posted on October 04, 2013 at 16:00Hi All, i'm using STM32F407, USB Device library V1.1.0 / 19-March-2012, i'm able to receive from PC to STM bytes using CDC, but i'm unable to send to PC from STM :( i modified function like this : static uint16_...
Posted on October 04, 2013 at 11:13I have found working solution. But for me it look ugly.uint8_t command = 0x55; uint16_t u16Temp = 0; u16Temp = GPIO_ReadOutputData(GPIOA)&0xFF00; u16Temp |= command; GPIO_Write(GPIOA, u16Temp); Is there better way ...
Posted on October 03, 2013 at 17:15 Hi, I developed an application using the STM32L152D Evaluation board and everything was working as expected. The application was then moved to the actual project which uses a STM32L151RD microcontroller...
Posted on October 03, 2013 at 09:50Can I configure two usart's to use one DMA? In datasheet there is table called ''DMAx request mapping'' and for stm32f40/1/2/3 eg. UART4 uses channel 4 for RX and TX DMA trigger on stream 2 and 4. Can I configure s...
Posted on October 04, 2013 at 04:46Hi, I'm trying t owrite robust code for USART communication with embedded modem like module. Since communication is not strict command-response manner, but module can send messages also in asynhrounous manner (spor...
Posted on September 20, 2013 at 17:30Hello, I am using a STM32F407. My application needs both USART1 and USART6 to concurrently receive data. I would like to use DMA2 to transfer data received from each USART to external RAM via the FSMC and ensure...
Posted on September 30, 2013 at 13:14 hello all and thanks for your help, I'm working with stm32f4 discovery board and I will like to use two different timers. For the timer TIM3 after a long work I set certain parameters so I can have my des...
Posted on October 01, 2013 at 08:03Hello I am Working with STM32F4 Discovery since couple of months.I have tried few basic program with this and now trying to do some more advance assignments like USB serial,CAN implementation with STM32F4 Dis...
Posted on October 03, 2013 at 08:47STM32L151RCT6A under IAR Compiler, board hangs when I do these steps /* Enable SYSCFG clock */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE); /* Connect EXTI1 Line to PA9 pin */ SYSCFG_EXTILineConfig(EX...
Posted on October 03, 2013 at 10:07Hi Gents,I am new to STM32 Discovery, and I am asked to do a project using Eclipse:- Is the codes and tutorials for IAR IDE compatible with Eclipse?- I need to read from sensors using Analog, UART & SPI, then I nee...
