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 November 10, 2015 at 11:26Hi.I am tying to connect my STM32F4 (or F1) with external ADC. Data from ADC can be received by SPI after ADC set ''ready'' flag.So the task for controller is to read by SPI 16 bit data on external event.The easie...

Posted on November 09, 2015 at 18:23Hi, I have recently got my SD card running on an STM32F7 with the SDMMC (with DMA) and came across one issue. The DMA request mapping in the Reference Manual (Table 25. DMA2 request mapping) indicates two streams ...
Posted on November 05, 2015 at 16:48Hi, I try to measure the CPU load of my STM32F429I-Discovery board. I tried the approach described on http://stm32f4-discovery.com/2015/05/cpu-load-monitor-for-stm32f4xx/. This shows me a CPU utilization of 99% in...
Posted on November 07, 2015 at 21:15Hi. I'm interested in that how you are programming - in C or in assembly language?What are really benefits of assembly in contrast to C? Speed of code execution probably? How much faster it is, if you compare the ...
