Posted on November 21, 2017 at 03:40I use stm32cubemx version 4.23. When I use SDIO 4bit and FATFS middleware, I see USE DMA Template option. If I choose 'disable', my code will run correctly. But If I I choose 'enable', I can't read and write data from uSDcard. I have some question :1. What does this option mean?2. What can I config (in stm32cube) to use this option?

Posted on February 21, 2018 at 23:29Hi.I've been struggling for couple days to implement micro SD card into my project. I click everything through CubeMX 4.24 with CubeF7 v 1.9.0. 4-bits SDIO, SDIO global interrupt and 2 DMA Channels for RX and TX. FatFS default.I moved to F746G discovery board to eliminate possible hardware problems but still couldn't manage to get the FatFS working.When i manually BSP_SD_init(); i get correct cardinfo, capacity and things... I also did testing procedure:BSP_SD_WriteBlocks_DMA(..)BSP_SD_ReadBlocks_DMA(..)BSP_SD_Erase(..)BSP_SD_ReadBlocks_DMA(..)with a success.But when i run project almost straight from the CubeMX i get empty cardinfo as probably fatfs does not init the sdcard. f_mounts doesn't return errors. It hangs/timouts on f_mkfs or f_open if i omit mkfs and format the card externally (FAT32). I've tried many various fatfs examples with the same results.Any known problems or possible configuration advices?#sdcard #stm32-f7 #sdio #fatfs

Posted on December 23, 2017 at 22:08Does anyone have a discovery board with a STM32F769NI release Z on it?I would like to know if they were already produced because the Ethernet bugin version A is not useful in production equipment.I hope to get a newer board one day.Thank you, Joerg

Posted on February 21, 2018 at 18:05Hello,Is there a simple way for the program to force a reboot of the STM32 device?  Can I programatically pull the line associated with the reset button low or is there some other way to do a hard reset on the board?Thanks,

Posted on February 21, 2018 at 11:51I would like to develope a new project and I need to use the HAL drivers of STM32F4xx in my IAR but I cannot find the relevant link and data on the ST website. I appreciate if you help me

Posted on November 16, 2017 at 09:01 Hi There! Hi have already post this issue but nothing changed from those time. May be i have ''unique'' version of qubeMX but this annoying bug chase me. When I change the Input frequemcy value I get this bug. Please look at the picture below. I can't return bach normal values - all of them in a float point state. It works for PC vercion and plugin of current wersion. Have somebody the same issue?

Posted on February 16, 2018 at 15:53I have a problem with an STM32F767 on a custom board with SDRAM and NAND SLC memory connected to the FMC.The NAND is 8 bit, the SDRAM is 32bit, so only the [D0:D7] signals are shared between the SDRAM and the NAND. When both the SDRAM and the NAND are configured & working any NAND data read is corrupted randomly.When just the NAND is configured the NAND data read is correct.The SDRAM always works fine with or without the NAND.The LTDC uses the SDRAM to hold its frame buffer - it uses the DMA2D to read the current frame from SDRAM at regular intervals.The SDRAM initialises and tests ok, I can see good display data on my display (no bad pixels or image corruption).However when I test the NAND (Erase a block, read Pages from the Block) I get random read errors that don't reproduce the next time the Page is read (1 Page = 2048 bytes).If I then disable the LTDC '__HAL_LTDC_DISABLE(&hltdc);' the NAND works perfectly with no read errors.So I conclu

Posted on February 20, 2018 at 10:27I'm trying to use TIM2 on the STM32F0-Discovery board (I am new to the STM32, but have used the STM8 before).I setup TIM2 and USART1, then in a loop I send the value of TIM2_CNT via the USART1, so I can see how TIM2 counts. Since the USART1 stuff is working at the intended 9600 baud, I am confident that the basic clock setup is there and the STM32F0 is running at 8 Mhz.However, I see TIM2_CNT count at about 50 Mhz, no matter the value of TIM2_PSC.Here is my initialization code:&sharpinclude <stdint.h>&sharpdefine TIM2_BASE    0x40000000&sharpdefine TIM2_CR1    (*(volatile uint16_t *)(TIM2_BASE + 0x00))&sharpdefine TIM2_CNT    (*(volatile uint32_t *)(TIM2_BASE + 0x24))&sharpdefine TIM2_PSC    (*(volatile uint16_t *)(TIM2_BASE + 0x28))&sharpdefine RCC_BASE    0x40021000&sharpdefine RCC_APB2ENR    (*(volatile uint32_t *)(RCC_BASE

Posted on February 18, 2018 at 19:46Hi, I've been dissecting the FMC_SDRAM example that comes with the STM32CubeF4 package.  I'm using the STM32F429 Discovery board.  The SDRAM chip it has on it is an ISSI IS42S16400J-7TL.One thing I don't understand are some of the comments in the main.c file of the FMC_SDRAM example with respect to timing configurations.  The code sets up the AHB to run at 180 MHz, but a comment in the code says:/* Timing configuration for 90 MHz of SDRAM clock frequency (180MHz/2) */I don't understand why they're saying the configuration is for 90 MHz when the clock is configured to 180 MHz.  Additionally, when configuring the SDRAM timings, it will make comments like in the following code:/* TXSR: min=70ns (6x11.90ns) */ SDRAM_Timing.ExitSelfRefreshDelay = 7;  // 7 clock cyclesI have the ISSI IS42S16400J datasheet and understand the 'Exit Self-Refresh to Active Time' is 70 ns.  However, I don't understand what is meant by th

Posted on February 19, 2018 at 18:29Hello Everyone,            I've got some strange behavior on the M24SR tag that I'm using. The last byte of an I2C data transfer either to or from the chip is being NAK'ed and looks to be throwing off the HAL drivers in the STM32 that I'm useing to talk to it. Is this expected behaviour or is it behaving oddly and if it is oddly then does anyone have any ideas. An example of what I'm seeing is attached.ThanksLuke

Posted on January 31, 2018 at 00:26I wish to place my Nucleo system into STOP1 mode and then have it wake up when a character is received on UART3. With the code below, I can successfully stop all the clocks and halt at the 'WFI' instruction. When a character is sent to the UART from my terminal, the interrupt routine runs and echoes the character back to me as expected, but the code remains stuck at the 'WFI' instruction (inside the call to HAL_PWREx_EnterSTOP1Mode). I have tried the code with and without the debugger and get the same results. How do I get the code to continue past the 'WFI'? My apologies for my use of the low level hardware instructions....I'm an old-school hardware guy so this is where I go when things aren't working!//**************************************************************************************__HAL_RCC_PWR_CLK_ENABLE();/* Ensure that MSI is wake-up system clock */__HAL_RCC_WAKEUPSTOP_CLK_CONFIG(RCC_STOP_WAKEUPCLOCK_MSI); USART3->CR1 &= ~0x000

Posted on February 19, 2018 at 16:14Hello. Attempting to prototype a proof of concept using the STM32F072 Discovery board with I2C & SPI ports (each with DMA enabled if possible). Upgraded the STM32CubeMX tool to the latest and very impressed with the look, feel and current kits. Now can actually see and select the Discovery board we have. However, after attempting to Start Project using this selection, receiving an error as noted. What are we doing wrong? Launching the tool with admin privilege does not change the results. If we proceed to Start Project using the CPU selection of STM32F072RBTx then the project can be launched as it should using this tool.

Posted on February 19, 2018 at 14:19In my attempt to create a BSP Audio Driver for Nucleo boards, I am having difficulty visualizing how to get data out of the incoming audio packets.Currently in my project, I am guessing where the audio buffers are located (by watching the memory for a block of data that changes every 1ms with the length 0x3E00) since I can't get that info out of the local USB Audio Device. Once I guess it, I set my DAC double-buffered DMA Audio to this address to play the data out thru the internal 12-bit DAC.Obviously, it is a ridiculous way to code since every time I re-compile the code, the buffer location is different. Also, since I have no way of sensing where the read and write pointers are pointing to in the buffer, it is hard to synchronize the incoming data to the speed of the DMA transfers. The results is that the audio plays, but very erratically.The USB Audio Device structures and variables seem to be local only. I'm assuming it is because the
