I need to do conversion between CHS addressing to LBA using the following formula:LBA = (( C x HPC ) + H ) x SPT + S - 1where,C, H and S are the cylinder number, head number, and the sector numberLBA is the logical block addressHPC is the number of heads per cylinderSPT is the number of sectors per trackbut I just don't know where and how to get those from a uSD card? Is there any way to get them using the MMC/SDIO HAL library or FATFS?

Hi,I'd like to reproduce the STEVAL-SMARTAG but I can't find the Altium project on the website. I have found the Altium files for the reader board (https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/st25-nfc-rfid-eval-tools/st25-nfc-rfid-eval-boards/st25r3911b-disco.html) and it would help to have the same for the tag.Thanks.

I'm using a ST25R3911B-DISCO for a project and I need to use the UART interface, instead of the USB one and the software provided by ST, to send commands (like INVENTORY, READ BLOCK, WRITE BLOCK) and receive the corresponding information.Is it possible with this board? And if it is, how can I proceed to implement it?Thanks in advance,Eduardo

Hi. Believe to have found a typo inside the STM32F429 datasheet (document DocID024030 Rev 10). Studying the use of the STM32F429NI DISC1 Kit and the use of the onboard TFT display. The source code is noting that the CPU is configured into AF14 (alternate function 14) which sounds correct. Yet the RGB pins are not correctly mapped under AF14 inside the datasheet. Specifically, Table 12 is showing that:PB0 = LCD_R3 (if using AF9) but should be PB0 = LCD_R3 (if using AF14)PB1 = LCD_R6 (if using AF9) but should be PB1 = LCD_R6 (if using AF14)The IAR source code mapping looks to be correct as it is working:and same typo in the STM32F750x8 datasheet?Please correct if my error.Thanks.

we are using nucleo STM32F429ZI (Cortex M4 uC ) running with the following configurations.Compiler : Keil, TruestudioFreq : 168MHzFPU : Single HardwareOptimization: O3 in keil, Os in truestudioWe have tested the user generated program 4096 point FFT. To complete the single time execution of the function take 110ms (FFT function is normally look like a c code, no pheriperals used, and even not initialized. GPIO only initialized for verifying the time of execution). But we had checked with Renasas (Cortex M4 uC ) and same software routine. We have used E2 STUDIO compiler to compile the code. when i execute the same code it takes around 320us . we compiled the project in E2STUDIO with the following configutation.Compiler : E2_Studiofreq : 240MHzFPU : Single HardwareWhat should i do to accomplish in the st32M429 to work same as Renasas controller speed (Approx 320us + 10%).I have attached my code for your reference.Thanks in advance.

We're looking at using the F413 for a slave in a many MCU product, and using its SPI bootloader so master can reprogram an array of slaves over SPI. I'm confused about the bootloader and flash programming, in particular:(1) Is high voltage VPP and high current on BOOT0 pin required for any flash programming? Or only advantageous in some circumstance? Or can I just use 3.3v?(2) datasheet says "parts are delivered with flash erased". So where is the bootloader? Do I need to avoid erasing the entire flash to preserve the bootloader? Or is it in ROM somewhere and mapped in only when BOOT0=1? Or is that Boot1=VPP? Thanks in advance for any clarification!Best Regards, Dave

Hi, i'm using SPI to communicate two STM32F446RE​Unfortunately, I get different value after the reset button pressed. Due to some other reasons, these two 446RE use LL and opencm3, but I don't think it is an issue. ​The code for master in one of the 446RE (LL):​ LL_SPI_InitTypeDef SPI_InitStruct; LL_GPIO_InitTypeDef GPIO_InitStruct;   LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_SPI3); LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_GPIOB);   GPIO_InitStruct.Pin = SPI3_SCK_PIN | SPI3_MISO_PIN | SPI3_MOSI_PIN; GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE; GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_VERY_HIGH; GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_PUSHPULL; GPIO_InitStruct.Pull = LL_GPIO_PULL_NO; GPIO_InitStruct.Alternate = LL_GPIO_AF_6; LL_GPIO_Init(SPI3_PORT, &GPIO_InitStruct);   SPI_InitStruct.BaudRate = LL_SPI_BAUDRATEPRESCALER_DIV8; SPI_InitStruct.ClockPolarity = LL_SPI_POLARITY_HIGH; SPI_InitStruct.ClockPhase = LL_SPI_PHASE_2EDGE; SPI_InitStruct

Dear Community,is it possible to download older versions of STM32CubeMX (4.X)? Unfortunately there are no links to archive downloads on the ST website. Thank you very much.Best regards,Emin Yagmahan

​Hi,I want to edit the given firmware on the ST25DV Discovery-Board. For that I have downloaded the KEIL MDK µVision 5 and was able to open the given project. But it's not able to compile because the file is too big. Can I use another Linker?

Hi everybody I am using st25r3911 in my own pcb and I still have a problem in the first step :rfalInitialize() does not return ERR_NONEin fact I see the MOSI and CLK and CS signal but there is not anything in MISO !!pin28 in st25r3911b (mcu_clk) is ok so i think the chip is working .

Hello, I am trying to use "STM32CubeExpansion_Crypto_V3.1.0" library for generating HMAC_SHA1 on STM32L431 processor. We are using FreeRTOS.Issue description: When we make a function call to the HMAC_SHA1 functions contained in the above library, it returns successfully with the HASH, but the code hangs immediately after that. Sometimes it gives "Hard Fault" and hangs and at other times it just hangs without giving any error message.Interesting thing to note is that, when we call the same functions from outside of any Task (from timer interrupt for example) it works just fine. But when we call these set of functions from within a task (say application task) the code hangs after executing the HMAC_SHA1 functions.Could anyone please point out what could be going wrong? Thanks.A few points to note:I am using the __CRC_CLK that is needed for running the crypto library.Have tried using critical sections - enable critical section before the HASH function calls and disable after returning fr

Hello,I need to use the example which boots (jumps) into application in external memory, but with a very slight modification:So that the start address of application can be somewhere inside the flash, not particulary at the start of flash, as it is not in example:(1) User application location address is defined in the memory.h file as:   -QSPI:  #define APPLICATION_ADDRESS      ((uint32_t)0x90000000)   -NOR :  #define APPLICATION_ADDRESS      ((uint32_t)0x60000000)   -SDRAM:  #define APPLICATION_ADDRESS      ((uint32_t)0xD0000000)   -SRAM:  #[define APPLICATION_ADDRESS      ((uint32_t)0x68000000)]​ Is that possible ?I mean, can I use different address, for example for NOR 0x6100000 instead of 0x60000000 ?My final goal is actually to have 2 different application in

HiI just started porting a project over to STM32. It does some complex stuff with timers. First I found out the the HAL doesn't support my usage of one pulse mode in timers. So I went for the LL API which I liked on first sight.Now I found out that the LL API only implements 4 of 6 capture compare channels of the advanced timer 1 of STM32F3xx.I need at least 5 CC channels. What can I do to get the rest of the CC channels?I started adding the missing functions and constants but I suppose I won't get it to run because I also need the corresponding interrupts and other functionality so I will probalby hit something not implemented in C.Best RegardsMichael Bürschgens

Hello,When is it planned to integrate freertos v10 with STM32H7 CubeMX ?Thank you,ran

Hello all,I just got my new toy before few days named as ST25DV04K Dynamic NFC/RFID Tag.I have downloaded the firmwares, applications and rest of the things from the https://www.st.com/en/evaluation-tools/st25dv-discovery.html#design-scroll.I have observed few things while I'm observing its code which is downloaded from same link and i've found that they have included the USB drivers but won't call even not trying to manage the input from the USB(If I'm not wrong).Now I want to use it through the PC software, for that i need guidance to to get suggestion like which software I have to prefer, how to manage the GUI communication for that what are the implementation I have to do in program, such things. Can anyone please help me for this and guide me.Little help would be appreciated.Thanks in advance.

Hi ST,I'm wondering about the sample rate of the LIS2DH* family and if the configured sample rate affects how the samples are captured. Specifically, when sample rate is changed, does that change how the samples are performed internally, or does is it the same process just happening less frequently? For example, if I switch from 10hz sampling to 1hz, does the chip integrate over a longer period while collecting each sample?thanks,paul

Hello everyone. I facing next problem:Just yesterday, TrueStudio worked perfectly, but program lost its lost capability to compile anything (not older project, that I compiled nicely till yesterdey, not new, CubeMX-generated projects).I'm getting build output just like on attached screenshot with every project.Also, I've got one of compile outputs, that consisted of messages like this: junk at end of line, first unrecognized character is '*'Only thing I could tie to what's happend, is that I've installed ASAP Excel utility, BUT I've DELETED it already, REINSTALLED TrueStudio, and getting same result.Also, CubeMX has updated it's libs today, but since older projects don't work as well, I don't suppose that it's him...No one beside's me didn't touched computer, so I'm pretty sure, that no preferences was changed manually.Any help/hints, what could it be? Thank you.Truestudio 32bitVersion: 9.1.0 Build id: 20181011-1241

We are using M24LR64E for configuration and event logging, try to use password to protect configuration data area. In the user manual(DM00047008.pdf), in Figure 12 and Figure 13, the password address is 0900h, but in Table13, I2C byte address is 2048, 2052 for different sectors.Another question is I2C_Write_Lockbit_area command doesn't have I2C data format (such as Figure 12, 13).ST25DV DVK has source code "st25dv.c" the firmware with all the functions for command codes, but I can't find the source code for M24LR64E.
