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 March 28, 2013 at 12:18Hi! I have a question regarding the maximum clock frequency for the ADC. The data sheet on STM32F407 gives maximum clock frequency for ADC as 36 MHz (Doc ID 022152, Rev 3, page 124) for power supply of 3.6 V. Howev...
Posted on April 01, 2013 at 21:23Hello, in my recent project I had to do some weird GPIO pin routings in order to get satisfactory PCB layout. I thought for a second, that maybe I have to do it again later for another project. After a moment, I've c...
Posted on April 01, 2013 at 11:06 I got a problem map a struct to Backup registers what I do is: /******************************************************************************************/ typedef struct { uint16_t actPageNo; uint16_t sollQ...
Posted on March 28, 2013 at 15:14Hi all,I am trying to compile the exemples that keil provide with MCBSTM32F200 in the folder C:\Keil\ARM\Boards\Keil\MCBSTM32F200 but I got problems in some exemples that are almost the same:In FTP demo i got ''all ...
Posted on April 01, 2013 at 08:21 Hi, I want to use the RTC's alarm A for waking up from standby. However, I cannot get the alarm interrupt. I am initialising timer 3 for interrupting every 5 seconds and reading the rtc within the interrupt hand...
Posted on March 30, 2013 at 15:09Hello, i used a STM32F4Discovery. My code is at the end of this text. The programm should release a interrupt by rising edge on PortD Pin0. Then the LED toggle on PortD Pin14. This does not work. Where is the mistak...
Posted on March 22, 2013 at 11:27Hi, I am using the STM32L151VB in a custom board. The problem I have is with the watchdog timer. The maximum time out is too less for me to do anything that I intend to. Right now I am using the TIM4 timer for a long...
Posted on March 29, 2013 at 06:45Dear everyone, USART_Printf demo provided in STM32L1xx_StdPeriph_Lib_V1.2.0 can't run on STM32L152-EVAL. I found that there is no output at ST3241EB Pin 11. However, I use PC10/PC11 (UART3) with another MAX232, t...
Posted on March 30, 2013 at 19:25HiI would like to apply an automatic system reset in case a particular condition in my system is met. I already know how to apply a system reset through software. Now I want also to do it via hardware. If If I pull p...
Posted on June 23, 2011 at 23:58In playing around with USART3, I'm attempting to configure it for DMX (250000 baud, 8 data bits, 2 stop bits). In fact, when configured this way, what actually seems to happen is that any data I attempt to send is ac...
