This problem continues in the last 4 version, and still not fixed. Some how I doubt it is stopped here. Stop the debugger execution and see where you are actually stuck. Stepping around in the high level code isn't going to provide you with answers. Is it stuck in the Hard Fault Handler, have one that prints out fault data, then you'll know it is there. Make sure the interrupt handlers are being called and functioning. Make sure all the callback functions are in place and being called. It doesn't end up in any of the error handlers. By the way, I managed to make the same code work in the version 4. One more note: I wrote the code piece with the help of. Make sure the naming there is correct and linkage to the vector table is working. Make sure those variables are marked as volatile. The problem is I may need to repeat this copy paste process every time I regenegerate project from STM32CubeMX, so can you please solve the problem in the next version? I also have the same problem. But I was not able to findany solution. I'm sure there are, I'm not much of a mechanic, I have a local garage to work on my vehicles. Thank you for the reply.

This is the relevant part of the code all other part is generated with CubeMX :. FatFs will fail when data returned doesn't meet expectations, or gets a low level error. This isn't the default and is a known issue. But the other pins of the display is not shared with SDIO pins. And I also don't get a low level error but a no file system error. They look fine, there is communication in every lines. All signals are V and looks "sharp". Can any one share complete project even with or without dma to get sdio 4 bit with cubemx 4. Or at least step by step procedure either in the form of video or pictures. Checked wiring and hardware, somewhere in the generated CubeMX code there is a problem, when mounting the device. Check SD present in generated code, my hardware goes high when present but generated code has the opposite. In the end i got it working by setting the SDIO clock divide factor to 3 and set the clock configuration as the following:. If you have overly aggressive slew-rate settings on the GPIO pins you might want to back them off. The SDIO is sensitive to bit skewing between the pins, make sure the trace lengths are equivalent. Any ideas how to solve that? Most everything should support 25 MHz, current microsd should support 50 MHz. But all the others, 4GB,8GB, My current poblem is that it is not possible to write to the sd card.

There is no big difference between them and you can treat them as the same peripheral with only different name. Read more about new HAL libraries. Main changes are these:. By default, this feature is disabled in library, but can easily be enabled. Default CD pin is PB6 when pin is active, but can easily be changed. For configuration, open defines.

You can force FATFS to use static buffer for all files not thread safe or to use stack for files, but you have to increase stack to allow that or you will have stack overflow.

The first flash sector starts at 0x Displaying counter2 works and shows me the value of counter-1but it works only once. If I write again to the flash nothing seems to happen. What is going on here? Can someone tell me why all variables change? Do I have to configure the linker? STM32 devices have flash on 0x and by erasing this sector, you did failure on startup because you erased actual part from where CPU loads instructions. Reading of counters is wrong. The best way is to create the new segment of flash in the linkescriptr and place the data there. It is the safest. If do not know linker scripts create a table of the one segment size, and place it at the end of the flash using your compiler directives. Learn more. Asked 2 years, 8 months ago.

All embedded software utilities come with a full set of examples. It is a graphical tool that allows configuring STM32 microcontrollers very easily and generating the corresponding initialization C code through a step-by-step process. Step one consists in selecting the STMicroelectronics STM32 microcontroller that matches the required set of peripherals. The user must then configure each required embedded software thanks to a pinout-conflict solver, a clock-tree setting helper, a power-consumption calculator, and an utility performing MCU peripheral configuration GPIO, USART. Finally, the user launches the generation of the initialization C code based on the selected configuration. This code is ready to be used within several development environments. The user code is kept at the next code generation. Source: STMicroelectronics. ADC - Analog-to-Digital Converter An ADC is a device that converts a continuous physical quantity usually voltage to a digital number that represents the quantity's amplitude. The conversion involves quantization of the input, so it necessarily introduces a small amount of error. Furthermore, instead of continuously performing the conversion, an ADC does the conversion periodically, sampling the input. The result is a sequence of digital values that have been converted from a continuous-time and continuous-amplitude analog signal to a discrete-time and discrete-amplitude digital signal. An ADC is defined by its bandwidth the range of frequencies it can measure and its signal to noise ratio how accurately it can measure a signal relative to the noise it introduces. The dynamic range of an ADC is influenced by many factors, including the resolution the number of output levels it can quantize a signal tolinearity and accuracy how well the quantization levels match the true analog signal and jitter small timing errors that introduce additional noise. The dynamic range of an ADC is often summarized in terms of its effective number of bits ENOBthe number of bits of each measure it returns that are on average not noise. ADCs are chosen to match the bandwidth and required signal to noise ratio of the signal to be quantized. If an ADC operates at a sampling rate greater than twice the bandwidth of the signal, then perfect reconstruction is possible given an ideal ADC and neglecting quantization error. The presence of quantization error limits the dynamic range of even an ideal ADC, however, if the dynamic range of the ADC exceeds that of the input signal, its effects may be neglected resulting in an essentially perfect digital representation of the input signal.

This is the 'simple' code it runs in polled mode. Ok, so updated this repo to be the complete example set. The initial part was a memory explorer which I have morphed into an SD card explorer as well. Note that if you're running this it will be most fun to have two terminal sessions going to your board, one for the debug stream and one for the console stream. Also tool chain is the launchpad.
