STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...

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...
