Posted on November 03, 2014 at 10:17I have an STM32F429 connected via FMC to a 16-bit wide SRAM. I can read and write to the SRAM correctly using simple memory writes.DMA works correctly too when I configure it with two streams; one to send internal...
Posted on November 20, 2014 at 21:48Hello - I would like to use STM32Cube w/open source tools. Is there an app note, etc., for using this w/one of the open source tools (CooCox or Yagarto)? Thank you much.
Posted on November 20, 2014 at 19:11Hi everyone, I am trying to download some code onto a development board and I know for sure that the code itself works correctly. But I'm getting an error saying that I haven't targeting the board correctly so I w...
Posted on November 20, 2014 at 00:50 Hello i want to test my BT on Discovery board. I connected all pins correctly and build easy code for recive data and turn on the light.In my code i use this function to recive data on STM. if (USA...
Posted on November 18, 2014 at 15:38Hello to all, For calibration I use Timer 5 Capture-Channel4 to measure the LSE Clock on a STM32F207 CPU. However the result was variing +- 20 Hz. To deviate external crystal issues I routed LSI to the Timer 5 cap...
Posted on November 19, 2014 at 19:39Hello,ST announced that everybody should use the cubeMX software (or at least libraries) because the old libraries will not be supported anymore. I was a noob on STM32 so I decided to start with cubeMX.It it clear...
Posted on January 22, 2014 at 20:31i use fatfs and i read at about 200to300KB/SECOND it's very low speed . i test sd card speed from computer and it's speed reading 12.5MB/SECOND how to speed up sd card reading i want about 5MB/sec are this hard ...
Posted on November 20, 2014 at 16:44Hi, Are STM32L0xx files (sch, lib, ref design) for Altium Designer available somewhere for download? In order to go quickly and avoid error..... Thanks
Posted on November 20, 2014 at 12:30Hi, I found a very strange behaviour for the UARTs: The IDLE Flag of UART4-5 will ''extinguish'' after typically 100-500msec (Baudrate 100kB and 9600). I tried with 2 Discovery boards and with all UARTs. The ''sy...
Posted on November 20, 2014 at 11:48 Hello, i am running compile (IAR AMR) in highest optimization settting, but sometimes it does ignores my code, or even functions that does have purpose; as example, DataRx[] is loaded by DMA with ...
