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 ...
Posted on October 23, 2014 at 14:05Hello community,Actually I evaluating DAC on NucF334R8. DAC1_Channel1 seems to work but I am not able getting DAC2_Cannel1 (Pin PA6) to work. I created the C Framework with STMCubeMX 4.4.0 - both channels with equa...
Posted on November 20, 2014 at 11:38Hi,I am using STM32f429 disco FW_upgrade code as bootloader for my application. I had seen it erase only 11 sectors (1MB) of flash memory. I want to erase upto 23 sectors from my application address, So i have mod...
Posted on November 18, 2014 at 14:54I am using STM32F103VCT6 controller in one of our product and we need to configure CAN bit timings to work at 125KBPS, 250KBPS and 500KBPS at clock frequency of 36MHz (max system clock on bus). I need to know two ...
