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 October 26, 2012 at 10:57 Hi Guys, Been trying to get the USART to work for a couple of days now and is time to get some help... This is my code: GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStru...
Posted on April 28, 2013 at 07:51Hello, I want to use UART + DMA to receive unknown length packet. So I tried to use IDLE interrupt to monitor the end of the packet. On the other hand, I use a PC tools to send several bytes data and delay a w...
Posted on April 25, 2013 at 20:46Hello, I am a first time poster on this forum so please bear with me. I am using CMSIS to get the DAC peripheral to play a simple tune. I am working off an example I found online which I have simplified to play onl...
Posted on April 27, 2013 at 17:44 Hello, I'd like to use 4 channels of TIM5 as independent pulse counter, but CCR1..4 seems to have some non-sense value. Here's the code: void TIM5_Init( void ) { GPIO_InitTypeDef GPIO_InitStru...
Posted on April 26, 2013 at 23:57Hello,I'm astudent of computer engineering, I'm trying to interface a STM32F0_Discoverycard with an LIS3LV02DQ accelerometer using the SPI protocol, but I'm havingtrouble with the initialization of the pins of the ST...
Posted on April 26, 2013 at 22:54 Hello, I'm trying to count pulse on PB7 using timer TIM4 ch2. Everything is ok, but I'd like to reset CCR2 so I can start another measure. I tried with TIM_SetCompare2(TIM4, 0); but CCR2 isn't set to 0 after execu...
Posted on April 26, 2013 at 12:53hi,I found a problem to generate a PWM signal like this one: i thought that we can do this with TIM1 by insertion of a DEAD TIME but when i inserted a dead time i obtained a signal lîke this one: can someone help me ...
Posted on April 26, 2013 at 17:00Hello to all of you ST lovers,I got a problem : working with ChibiOS (which includes the stm32 libs) I'm trying to enable some DMA actions (to capture a timer value, as it happens). Yet whatever I do in the DMA1 Stre...
Posted on April 26, 2013 at 10:34Hello,I'm working with a STM32F407 controller board. Right now, I want to trigger a DMA transfer with one of the internal timers (TIM1). The DMA transfer should read one gpio port and put it into the memory. The time...
