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...
Posted on January 24, 2017 at 14:39Hi,I'm using latest version of Cube (download 20.01). I'm trying to read ADC-values from SPI with DMA. Read is activated on ADC-dataready.#define ADC_BLOCK_SIZE 24uint8_t tempBuf[ADC_BLOCK_SIZE ];// This interrupt ...
Posted on January 23, 2017 at 18:35As the title says, can the analog watchdog high and low thresholds on F4xx be reconfigured while the ADC is running?I vaguely recall reading somewhere that it could be changed dynamically at any time but can't for ...
Posted on January 20, 2017 at 17:05HiI used STM32CubeMX and configured a project using RTOS and USB_DEVICE (I am trying to run the USB CDC functionality with the FreeRTOS). The program runs until it hits the USB_CoreInit function inside stm32f4xx_ha...
Posted on May 11, 2016 at 23:34I have project generated by STM32CubeMX 4.14.0 and STM32CubeF7 1.3.1. I use the FATFS and SDIO with DMA. If I wrote a file with higher clock for sd card, then there is an error in the function FR_DISK_ERR f_write. I f...
Posted on January 24, 2017 at 07:58Hi,We configure the timer 1 to run a PWM signal on PA8 & PA9.It works well with the debugger, but when we power the MCU directly, the PWM is not running ! (We can confirm that the main is running... with a manual G...
Posted on January 23, 2017 at 23:01The 32F413HDISCOVERY webpage, and also the data brief DocID029964 Rev 1, both say the kit has:USB OTG HS with Micro-AB connectorhowever, the STM32F413 has 'only' an USB OTG FS.Also, on the picture of the DISCO's P...
Posted on January 23, 2017 at 23:11In synchronous mode, USART_CR2.LBCL allows to omit the clock pulse associated with last data bit.Why?The text in 'USART synchronous mode' chapter hints thatDepending on the state of the LBCL bit in the USART_CR2 re...
Posted on January 08, 2017 at 21:24Hello all,I'm currently working on a bridge that takes in artnet packets (theatrical lighting control) and spits it out as data for ws8212 leds.I've got working code setup and running on an olimex stm32-E407 dev bo...
Posted on January 13, 2017 at 00:15I've run out of DMA channels so I can't run SPI2 with DMA both ways. Since I'm talking to an external NOR flash chip where reading data is of much higher priority than writing I'd be happy with RX only DMA.Setting ...
