Posted on May 09, 2014 at 15:48Hello, i'd like to do output compare on four pins: PE13, PE9 (LEDS), PA10 and PA12. Everyone works except PA12. I tried to do that with TIM16 and TIM4 with no luck. And i reconfigured the channels, i understand how the...
Posted on May 09, 2014 at 14:34I have been looking in the stdlib libraries (v 1.0.2) for the STM32F401VE, and there does not seem to be any support for SPI4, even though it is listed as existing in the datasheet and reference manual. What gives?Have...
Posted on May 09, 2014 at 15:48Hi, Has anyone started using V1.0.7 Keil.STM32F4xx_DFP.1.0.7.pack? We are considering to use it as a part of medical product development. I also do not see any example codes as a part of this pack (particularly requir...
Posted on May 09, 2014 at 12:25Hi all. I'm trying to work with ADC and DMA. The adc works, i'm able to read directly value form pin PC1. When i try to read it using DMA a get alway zero value. I'm try to get work example from stm32f4_dsp_stdperiph_l...
Posted on May 08, 2014 at 17:48Simple question - should be answered in datasheet, errata sheet, or ref manual but I cannot seem to find it. I am wondering how much ADC readings drift relative to the reference voltage with temperature. If I have a co...
Posted on May 06, 2014 at 07:17Is there a tutorial or lecture series for beginners working with a STM32F3 demo board? I have programmed simple project boards like Arduino, but not anything like the STM32 boards. I have tried to work backwards from t...
Posted on May 06, 2014 at 00:33Dear, i have the following issue: i have seen that i cannot process too many instructions from inside interrupt. I guess there is a limit. (still didn't looked the datasheet), So i decided to do just some few operatio...
Posted on May 08, 2014 at 20:36 Hello, I'm trying to use the PC13 as an output but I can't get any signal change from it. I'm already setting the pins PC14 and PC15 as inputs following the datasheet orientations. I used one of the ...
Posted on May 08, 2014 at 11:57How could I write some code that would access a memory address and wouldn't generate a bus fault if it was incorrect? Or failing that, is there a way to safely check if an address is valid, or maybe even a way to have ...
Posted on April 16, 2014 at 12:36 Hello, I use a STM32F427 running with FreeRTOS. I try to create a file on my SD card, through SDIO, thestm32f4_discovery_sdio_sd.c (DMA mode). I also use the librairyFatFs R0.09, ported by Clive I ...
