Posted on February 06, 2016 at 09:47Good afternoon for all.In flat interrupt model of other processors after entering in handler all interrupts will be disabled automatically as normal. For implement nesting you must enable interrupts by himself. Th...
Posted on February 04, 2016 at 18:24How to use DMA with SPI? Im trying to send image from SDRAM via SPI to LCD on STM32F429i-disco board: void LCD_ILI9341_SendImageFrame(uint8_t* data) { ILI9341_WRX_SET; ILI9341_CS_RESET; HAL_SPI_Transmi...
Posted on February 02, 2016 at 02:10I'm learning about the whole STM32 environment (specifically using an STM32L4 Discovery board) and trying to use the STM32CubeMX software.Under the USB peripheral, there are a number of options that make reference...
Posted on February 05, 2016 at 18:34Howdy, I'm working on a project that will receive DMX using the STM32F070CBT6. I have PA1, configured as USART4_RX, connected to my DMX input via an RS485 transceiver. Most of this is straightforward, but I have a...
Posted on February 05, 2016 at 12:38Hi. I have been programming my new nucleo_F103RB, a bit lately and I have noticed lately that when I program the micro with whatever I'm working on, the program finally runs after ST-LINK has finished. But when I ...
Posted on February 05, 2016 at 04:13 I am experiencing difficulty getting the spi slave to transmit data. Receiving data works perfectly and correctly, transmitting however doesn't. Initialisation code: GPIO_InitTypeDef GPIO_InitSt...
Posted on February 05, 2016 at 23:28Hello!I'm trying to use a generated code by the STM32Cube software (for a STM32F205 device) to read a sequence of ADC channels using the DMA in circular mode, and I'm facing some annoying problems: The code is s...
Posted on February 02, 2016 at 17:01Thanks for any help. I'm confused on how to connect VREF+. I see that it can be used as an reference voltage output, and I now have it as No Connect. VDDA is connected to its pin, which seems to provide the voltag...
Posted on January 26, 2016 at 10:54Hi friends , I found following and did not understand why __set_MSP(0x20002000) , why main stack pointer hold 0x20002000 ; why not 0x20000000 (sram start address) for stm32f429. When I debug and look in 0...
Posted on February 04, 2016 at 14:21Hi all: I am developing a device with an STM32F407. The device will always be powered by its own power supply. It will have a USB socket so that it can act as a ''USB device'' (a USB slave) that shows up as a s...
