Posted on January 20, 2017 at 06:22I'm learing stm32 spi,In normal way of master mode, I have to low the slave select pin, then transmit data, then high the slave select pinI know that I can use dma to transmit data,but I am not sure that dma can co...
Posted on January 24, 2017 at 22:25I asked a question earlier on how to generate n-Pulses from STM32 to drive a servo like interface -> https://community.st.com/0D50X00009XkdsSSAR, and it worked. This feature is available only on TIM1/8. Is there a ...
Posted on January 24, 2017 at 18:54I am building a peripheral device that will use an STM32 microcontroller. This peripheral device will communicate with a master/supervisory device over a CAN interface. We have tentatively chosen the STM32F091CC ...

Posted on October 31, 2016 at 12:13 Dear all ST staff, I found a small bug in CubeF7 v1.5.1. Bug found at preprocessor macro definition of ''FMC_SDCMR_MODE_2'' at stm32f7 register definition files(stm32f745xx.h, stm32f746xx.h, stm32f756xx.h...
Posted on January 25, 2017 at 11:07Hi,I try to implement a timer with interrupt routine, but it always hangs after the timer is activated. This can be seen if I use the debugger over SWD: when I execute the next command after TIM_Cmd(TIM2, ENABLE); ...
Posted on January 23, 2017 at 18:27Hello,e.g. RM0377 lists the PWR_CR_LPDS bit unconditional for all L0X1 devices. * @version V1.7.1 headers define PWR_CR_LPDS only for L011 and L021. Is this right?#stm32l0
Posted on January 24, 2017 at 11:54Hi allI'd like to use UART2 to receive data, but It seemed to be failed, only could transmitted data.I used the same codes in UART1, everything is fine,So I think HW and SW parts are fine except UART2.I had not con...
Posted on January 24, 2017 at 15:09I have looked at PM0214 Programming manual for STM32F4 series for functions like GPIO_Write() and GPIO_ToggleBits() but they don't seem to be there. Is there a document that describes peripheral functions or does o...
Posted on January 24, 2017 at 15:27Hi allI'd like to use UART to receive soe fixed length datas, ex.'1234567890'.uint8_t buff[10]; hal_uart_receive_it(&huart, buff, 10); or hal_uart_receive_dma(&huart, buff, 10);How should I do and then make sure th...
