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 October 29, 2013 at 16:57I'm unsure on how to use the FIR interface. From the provided example: int a[N];/*filter output vector*/ short x[M+N-1] = {x0,x1...,xM+N-1};/*filter input vector*/ short h[M]={h0,h1...,hM-1};/*filter coefficients v...

Posted on October 31, 2013 at 09:23 Hi All, a couple of questions about the RTC Alarm. I have got the RTC Alarm working (using LSI), and raising an interrupt (RTC_IRQHandler()) successfully, but I'm stuck on the following:- 1) I would li...
Posted on November 13, 2013 at 14:44I'm trying to use spi to talk to a EEPROM. It has a cs setup time of 200ns. I'm wondering if I can set the CPHA to meet the requirement in case the spi speed is in the proper range. Is this the purpose of clock ...
Posted on November 13, 2013 at 14:05HelloThe original program was tested on STM32F407ZG MCU, but I need to have it running on a STM32F427ZI.On the 407 the code was running fine, but when I start the debugger with the new modified program it stops at...
