Posted on September 16, 2014 at 17:38I'm concerned with the communication between two stm32 devices via 4-wire SPI interface, no DMA, Keil RTX. The first device (SPI master) is a base board with stm32f427, the secind device (SPI slave) is a display ...
Posted on November 03, 2014 at 10:14I work with the Wakeup pin (PA0) as STandBy wakeup.When I set PA0=''0'' change it to WakeUP pin and then enter StandBy. When I make PA0=''1'' it get out of the Standby state and work as usuall.But when I enter to...

Posted on October 31, 2014 at 21:24I have a strange problem. I use the code below on the STM32F05 series and it works just fine. Transfer it to the STM32F072 and it does not work. When applying voltage to any given port, the ADC readings change on m...
Posted on April 30, 2014 at 17:03Hello all,I am strugling with an spi communication between my ''stm32f3discovey '' and a resolver chip AS5311.Took me some time but I managed to make the clock and the communication working has I can see on my scope....
Posted on November 03, 2014 at 18:32Hello, let us assume I want to put all pins of GPIOA into pull-up, but don't need GPIOA later. After enabling RCC_AHB1ENR_GPIOAEN and setting the mode in GPIOA can I safely disable RCC_AHB1ENR_GPIOAEN again withou...
Posted on November 02, 2014 at 13:52STM32F429V has 100 pins and support RGB565. In order to support TFT LCD, more memory is needed. Does it need to add external SDRAM? 429 has 256k internal RAM. Is it enough to support TFT? Actually, the application...
Posted on November 03, 2014 at 15:41We are facing problem with 24-bit RGB888 mode. Most of the time 2-3 LSBs of R, G and B have noise data coming out. For some particular pattern of data like all 1s written to frame buffer the data coming out as ex...
