Posted on January 03, 2013 at 22:11Hi everyone,Whenever I use either of the multiblock read/write functions the peripheral gets stuck in the SD_CARD_SENDING or SD_CARD_RECEIVING state, respectively. Further attempts to access the peripheral in this ...
Posted on November 19, 2014 at 17:29Hello,I'm having problems with bit timing configuration. I have 36MHz peripheral clock and need 500kBit/s on CAN. I'm having trouble, because I've calculated right value but I see on the oscilloscope that it isn't...
Posted on November 19, 2014 at 17:07I am having trouble to wake up the STM32F407 from the STOP condition using a GPIO EXTI line (PB 0). The same GPIO line is used when the STM32 is ON to switch it OFF (THIS WORKS PERFECTLY) and whenever it is OFF ...
Posted on November 08, 2014 at 03:50the i-nemo forum is a little slow hopefully maybe i can get a faster answer here...I'm trying to interface with the LSM9DS0 and I can't get any coherent information from it. when I try to read the who am I registe...
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 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 ...
