Posted on February 10, 2018 at 18:38Hello,I've tried accessing the MOOCs courses, I got a confirmation email about my registrations but I never received log-in details after registering for this. Are you still running this course? If so, how do I ge...
Posted on February 08, 2018 at 15:49 Hey everyone, I'm using a STM32f722ZE. I wanted to know if I allocate two 32KB buffers. One being in SRAM1 and the other in DTCM, With a double buffer DMA2, can the CPU and DMA run in parallel? To my underst...
Posted on February 09, 2018 at 14:52STM32F4xx HAL drivers V1.7.3 / 22-December-2017I get some data by HAL_I2C_Master_Receive_DMA() and HAL_I2C_Mem_Read_DMA()I found that a wrong Slave address could be sent when using the HAL_I2C_Mem_Read_DMA() due t...
Posted on February 10, 2018 at 01:57Dear ST, when would you think, the 208 pin part will be available ?https://www.digikey.com/products/en/integrated-circuits-ics/embedded-microcontrollers/685?k=stm32H #h743-208
Posted on February 09, 2018 at 00:47I would like to know if there is a possibility from the Atollic channel TrueSTUDIO on You Tube, that tutorials are uploaded from scratch, that is, from the simplest as creating a project, loading libraries, import...
Posted on February 09, 2018 at 18:00For an industrial application I use 3 timers, two for encoder input (TIM1 and TIM4)and one with a combined XOR (TIM2).Source signal is the same for all 3 timers.An interrupt callback for the XOR timer saves the el...
Posted on February 06, 2018 at 12:56Hello.I have a problem with QSPI. I try everything, but program doesn't work.I split my program to some parts.qspi_gpio_ini(); /* Init GPIO pins */ qspi_dma_init(); /* Init DMA */ qspi_init(); /* Init QSPI */ qspi...
Posted on February 08, 2018 at 10:03Is there any posisibilities to clear SPI FIFO before calling to HAL_SPI_Receive_DMA ? If We don't do it than we get old data in read buffer. I found that only way to do it, is reading RX so many times, as the fif...
Posted on February 09, 2018 at 15:52 Hello! I want to program a STM32L073CB device FLASH and option bytes and then to start the application. If I don't program the option byte I have not problem with the application start. That is the command line...
