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 September 04, 2013 at 18:36 Hi I'm faced to a DMA who don't want work ... I have look all around (this forum , internet , crystal ball .. ) but i don't know why my screen stay blank :( I use a 320 x 480 (ILI9481) tft screen ...
Posted on August 30, 2013 at 03:17hi guys i'm new to stm32, i got a problem that i used sdio and fatfs to test maximum speed of write sd card, its only around 330kb/s but when i try to use sd card reader its up to 2mb/s, so i want to figure out why ...
Posted on September 04, 2013 at 18:14I'm trying to flash a custom bootloader to one of these devices: http://www.mikroe.com/mini/stm32/, and they seem to have protected their bootloader. I'm using an STM34F4discovery board for SWD, and OpenOCD (0.7...
Posted on September 04, 2013 at 22:45Hello everyone, I'm trying to transfer 2 bytes using SPI in master mode and DMA. Additionally I have to set and reset CS signal by software. CS signal is low before starting transfer and is high after transfer.So...
Posted on September 04, 2013 at 21:37Hi,For my project I need additional RAM, is it possible to add memory to the STM32F407VG (in the STM32F4-Discovery Board) using the FSMC interface?
Posted on September 04, 2013 at 22:21I made a mistake, it's the STM32F4-Discovery which has 8 address outputs.
Posted on September 03, 2013 at 17:15Hi, i'm working with a STM32F207VGT and i dont achieve to wake up my board from STOP mode with the RTC. The RTC is configured with the LSI because the external crystal for LSE is not mounted. I have read another ...
Posted on September 04, 2013 at 16:39I�m trying to configure 2 external interrupts in STM32F2 at the same time. These interrupts are attached to PF11 and PG11 GPIOs pins. How can I do it? When I try to select the GPIO used with the function SYSCFG_E...
Posted on September 04, 2013 at 08:22My platform's MCU is STM32f205. I try to modify TIM10_PWMOutput example from STM32F2xx Standard Peripherals Firmware Library to generate one PWM signal by using TIM10_CH1function of pin PB8. But it doesn't work?...
Posted on August 19, 2013 at 13:59I may have some spurious or unhandled interrupts and want to see where and when with software catch. Is there a default (in absence of specific) IRQ handler i can overwrite / install? (E.g. as you would with HardFa...
