Posted on April 01, 2015 at 18:22Hi I read the AN4031 application note ''Using the STM32F2 and STM32F4 DMA controller''. In this document it is mentioning that the AHB Multi layer bus has an Arbiter on each layer, which handles the bus arbitration ...
Posted on March 25, 2015 at 18:37I can't seem to find any statements about plans for ST to deliver a Nucleo board with a STM32F7 chip. I would appreciate any pointers or news you might have. Is it worth waiting for a bit, or is it time to experimen...
Posted on March 30, 2015 at 21:45 Hello All, I'm a hobbyst, and recently bought a Nucleo evalboard with STM32L152RE MCU for experimenting the Cortec MCU from ST. I use the free/demo dev environment from keil(MDK V5).I also use the STMCUBE...
Posted on April 01, 2015 at 03:31 Hi all, I configure my stm32f302's usart without peripheral lib, when i enable it with CR1->UE, the usart interrupt keep triggered and CR1->UEbit cleared automatically, actually i didn't connect anything to RX a...
Posted on March 30, 2015 at 11:26Hello, I try to make a demoboard with a STM32F4 controller but I have some problems: Which pins I need to use the stlink programmer from a nucleo board (swdio, swclk ,... )? I found in the datasheet, that some functi...
Posted on March 30, 2015 at 14:16I am using STM32F207 VG controller for my learning.I have few following doubts.I want to use timer for up counting.Timer clock is set to 36 MHz.I want to generate timer interrupt for every 1 ms.With what values i nee...
Posted on March 24, 2015 at 16:46 tl;dr - after converting your project to 4.7.0 check all of the generated code carefully. I have ADC1 set up so that ranks 1-4 are hooked to channels 0-3 respectively, rank 5 is hooked to vbat, an...
Posted on March 31, 2015 at 13:57Hi, I have tried to find some information about registers signalling the cause of a hard fault on an STM32F072 but couldn't find anything useful. If anyone could give me some directions I would be glad. Regards, Kil...
Posted on March 30, 2015 at 16:46 I am currently trying to generate a squarewave on A8 with TIM1 (50% duty PWM1) and use TIM2 as a slave to trigger an interrupt every 4096th tick (this is used to reset the counter of an LED driver and to push ne...
Posted on March 27, 2015 at 17:23 It would seem VREFINT magically turns on after coming out of sleep/stop even though it is not being used on the STM32L053 (nucleo board). It turns off for the first sleep/stop, then it wont turn off again. The M...
