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...
Posted on August 13, 2013 at 17:12Hello Allm I am prototyping with the STM32 F3 Discovery board and using the ST standard peripheral library. I am also using some example code that contains a function - Delay() - which uses the SysTick_Handler to d...
Posted on August 13, 2013 at 14:23Hi, I have a simple question regarding internal SRAM size of STM32F373Rx processor. Datasheet (rev.3, table 2 on page 10) specifies SRAM size of 24kB for 128kB Flash units,but I can read and write up to 32kB of SRAM...
Posted on August 08, 2013 at 23:31Hi,I have what is essentially a timer question. I am interested in using an STM32 F4 (more RAM, higher clock speeds) for an application. My application requires me to generate a pulse every 2ms, pulse length ~100 us...
Posted on August 13, 2013 at 11:41Hi, I am using DMA1 on an STM32F103 to collect data continuously from ADC1 as it cycles thru a regular conversion group. Every time the DMA transfer complete interrupt fires I post an event to look at the data and ...
Posted on August 12, 2013 at 13:27Hi, on my STM32F0 discovery board I configured the clock source to be HSI with a system_stm32f0xx.c generated by the clock configuration tool . That seemed to run like it should. Now I pulled JP2 and supplied Vdd pi...

Posted on August 12, 2013 at 21:48 Hello guys, I need some help. I want to create a large buffer in the sram and I'm having some problems with the compiler. I want to use the 112KB SRAM memory (pag 52 - RM0090) for my buffer. But when I w...
Posted on August 12, 2013 at 20:35Hi,I want to sample a fast timer (125ns) when an EXTI interrupt occurs, before the interrupt is handled. Later when the interrupt is handled i want to be able to compare the actual value of the same timer and measur...
Posted on August 12, 2013 at 14:30Hi I tried to turn on the master clock for the SPI/I2S bus on the STM32F3 microcontroller by setting the MCLK enable variable in the initialization struct for the I2S 2. But I couldn't get any signal on the PA8 or o...
Posted on August 09, 2013 at 00:46Here's the situation - I'm transferring some data from I2S to a buffer in memory via DMA. The DMA is set up to be double buffered - I'll skip all the initialization code but here are what the DMA registers look lik...
