Hello,We intend to use a font which was installed correctly but was not listed in TouchGFX under the Font column in Typographies.After some investigation, we found the font contains a space in its filename, e.g. "Sample Font.ttf". After removing the space and reinstalling the font it is listed correctly.The workaround to remove the space and re-install the font works fine for now, but requires each developer to follow this step for a font that is pre-installed on our computers - hence this bug report.

Hello​.I have got a bootloader and application that both work separately.I want to combine from both file to one hex file using SPC5studio.Is there any option and setting in SPC5studio?Thank you in advance.

Hello,I was searching this forum and already found lots of help, but unfortunately I'm stuck to this issue. The Guide refers to CubeMX 5.0 and some things seem to be corrected since this version i.e. C/C++ combi project... but still CubeMX does not generate an Atollic project including TouchGFX that does compile and so far I was not able to fix it. Actually this is bit frustrating as TouchGFX together with the other stuff is all part of STM and promised as working solution...So Maybe someone here has done this succesfully and would be so kind to share the .ioc file or give an updated step by step manual for the new software release as I'm sure I just miss some tiny things...Thanks in advance and best regardsStefanPS: Without use of TouchGFX I can create a working project with CubeMX and also when I use the TouchGFX standalone and flash the Board from the Designer it works.

I am trying to run a clock demo from TouchGFX 4.10.0 Designer for my STM32F769-DISCO.But when i Run on target the detailed log shows the erroe:" there is an error occured during flash.  Please make sure you have the right target connected."PS:I am sure that i have choose the right target.

How to get interrupt state (enabled or disabled) via HAL?In my void I need to do HAL_TIM_OC_Stop_IT() only if this interrupt enabled.

Is there any example source code that I can use for controlling CR95HF from user space application in Linux using UART?

Hello,I read ref manual part about SYSCFG (STM32H7 in my case). There are some regs that have an undefined reset value and the meaning of the regs is so that the contents is important at HW reset (BOOT_ADDx, BANK_SWAP). These regs are marked read only. I couldn't find anything, how to set the values and where they are stored. Can I change them somehow from my software, ie change the boot address or swap the banks for the next reset?General topic is to design a custom bootloader that will also be called after reset when BOOT0 is set. Also a fall back to the previous version after a corrupted firmware upload would be nice.Thanks a lotMartin

After unzip a STM32CubeL4 Rev 1.14.0 file.I open B-L475E-IOT01_BSP_User_Manual.chm file. It hasn't texts in each item.But Rev 1.13.0 has texts in each item.I am not sure this file is incomplete in a ZIP file or not.

Hello, I installed the latest driver version Unico 8.0.0. Now my board is shown in the decive manager.Ready to use.. Everything looks good.Now I am trying to update the FW in the STEVAL-MKI109V3 board. First I pressed the BT2 Button and pluged the USB into the Laptop(Win7 and Win10). The blue LED (D6) is on, but there is no available DFU Device in the DfuSe Demo (v3.0.5). I noticed that, when I unplug the device and replug it without pressing the BT2 button, the LED (D1) no longer blinking as it did before. As if I was stuck in DFU mode.If I press the BT3 vor reset the LED (D1) is on for half a second. does anyone have any idea what this could be or how I can update the FW?Best regards,Chris

Hello,I'am new on using CubeMX and HAL functions. I would like to know if interrupt callback functions, that can be use for execute some code after ISR, are executed from inside interruption scope.I'm asking that because as a programing good pratices, code executed within interrupt routine should be as short as possible to avoid latency and nested interrupts. So, if _callback runs within interruption it should be short either.Thanks in advance.

Hi All,Our board has touch screen of resolution 480 x 272, surrounded by a touch sensitive area containing 11 touch sensitive buttons. The touch controller handles the screen and the touch buttons, we have coding written C workinghandling this. Also, we have SDRAM with 64Mb with 16-bit data interface. The on board micro is the STM32F429. So far all the code is written in C using Keil uVision. Handling out custom touch buttons, is that just a matter of creating a custom callback for touch interface handler? if not please suggest how it might be handled.The aim is speed up GUI development and use our existing non-GUI code.Kind RegardsMikeZ

Posted on June 19, 2018 at 19:10I need to integrate an NFC reader for medical device pairing. I already designed a tag for the sensor which works with my phone.The next step for me is to add an NFC reader to the portable monitor. The biggest antenna I can fit into the back of the monitor is about 15cmx10cm and as it is quite big, I picked the ST25R3911B to drive it because it has good power. I need a read range of about  20-30cm. Apparently, the best standard to achieve such range is ISO15693. My current tag uses ISO14443/B but I can easily swap the IC with something like the MLR24LR.The sensor has a zigbee chip, and I only need the NFC to exchange the encryption key (about 128bytes with all metadata), so datarate is not important.Some info:- Tag is 45mmx35mm, using TI RF430CL330, but if ISO15693 is preferred, I can swap the IC and redesign the PCB.- The max antenna I can fit inside my monitor (NFC reader) is 15cmx10cm.- I need to pass 128bytes of data.

Posted on November 03, 2017 at 16:04Hello everyone,As several people on this forum, I am trying to implement some kind of 'USB keyboard' with an STM32F103C8.I am working with truestudio and cubeMx, and I use the USB library provided.I have update the descriptor and I have no problem to send keys and modifiers to the computer, reproducing exactly a keyboard behavior. However, in those examples : STM32Cube_FW_F1_V1.6.0/Projects/STM3210C_EVAL/Applications/USB_Device/CustomHID_StandaloneSTM32Cube_FW_F1_V1.6.0/Projects/STM3210C_EVAL/Applications/USB_Device/HID_StandaloneI have not seen anyway to read the report provide by the computer about the LED states (Caps Lock, Scroll Lock, Num Lock). My descriptor includes an output report for this information.  In fact, I would like to know how it is possible to implement the same function as 'USBD_HID_SendReport' to 'receive report'. Or more simply, where can I find an example doing that?Thanks for your help!#usb-hid-keyboard #stm32f1

I am trying to find the datasheet, reference manual for STM32 Nucleo 144 - F429ZI board.Basically, the document which talks about Functional block diagram - how the GPIO pins are connected to which bus. Next, I am looking out for the reference manual to program the registers. I have got some documents but then I realized they were for discovery board but I am looking for the STM32 F429ZI - Nucleo 144 board.

Hello All,I recent implemented a DMA transfer for SD card data to RAM (technically an external SDRAM) on the STM32F765VI. Previously we had been using an IT transfer. In other words, we are now using SDCard_WriteBlocks_DMA rather than SDCard_WriteBlocks_IT. The original motivation for this change being the fact that 480,000 byte size IT transfers to an from the SD card cause roughly 20 thousand ISRs, whereas the DMA method only causes 4 ISRs total (2 SDMMC dataend ISRs and 2 transfer complete DMA ISRs). I expected a large performance increase, but ended up actually getting a slight decrease in performance. Both methods take roughly 0.5 seconds. This is with the clock running at 200MHz. All of this is single threaded without a kernel. I am using a 4 word burst on both the peripheral and memory side of the DMA. I wanted to ask the community if these speeds are typical, and if not, does anyone have any recommendations on how to speed up the transfer?I could add a double buffer, but it see

Hi everyone,I have been trying to just test the ethernet on the STM32H743zi nucleo board.The problem is that the example does not compile in any way. I assume it's because I am using the very obscure, not intended for STM32, atollic true studio and there isn't any example for it.Anyway I try to import the SW4STM32 and it seems to be fine. I checked most of the include paths and they are fine. However nothing is included.The deprecated_definitions.h isn't included, I add that manually to the project folder and a ton more stuff is not included.I even checked and the example is including ARM_M4F port for freertos! I honestly just want to check if the hardware is working, not spend a day with software problems, program the board and then not be sure if it doesn't work because of something I missed in the software.Why not also provide the .elf to program? Anyone can provide a working .elf demo for the nucleo board?I have been trying to use STM32CubeMX to create a LWIP project and I've compa

All,I am getting an issue when attempting to write to the SD card using a ​DMA burst transfer. I am transferring bytes to words in burst sizes of 16 beats to 4 beats respectively. I am using the full FIFO and direct mode is disabled. Memory is incrementing and the peripheral is not. After debugging it has become clear that my transmit complete and FIFO error both trip as I am configuring the SD data path state machine, which happens in the application code after I have already enabled the SD and DMA for the transfer. This does not happen when I set up the read in a similar fashion. This happens right after this line of code is executed /* Write to SDMMC DCTRL */ MODIFY_REG(SDMMCx->DCTRL, DCTRL_CLEAR_MASK, tmpreg);I am configuring the SD as follows.    /* Configure the SD DPSM (Data Path State Machine) */    config.DataTimeOut  = SDMMC_DATATIMEOUT;   config.DataLength   = BLOCKSIZE * Number

Hello,I am having issues with using the DMA to transfer SD card data to RAM. This may have to do with my configuration settings, because the FIFO error register is automatically set when I configure the SD card DPSM (not when I enable the DMA configuring the DPSM happens after enabling the DMA in the HAL). I get small transfers to work just fine, but larger transfers that almost fill the DMA 16 bit counter are causing issues. It seems as thought the SD card is offsetting the data being transferred after my first few transfers. This offset only happens once, and then is consistently wrong. It seems as if the destination on the SD card is correct, but it is pulling from the wrong memory address. Even though I check that the memory address that I insert into this writeblocks function is the same every time. I should say that the DBKEND bit is being set in my smaller transfers, but not the larger transfers. My smaller transfers also don't require that I poll for the SD card status because

Hello:Previously using CMSIS, I was able to read or read/write this accelerometer device. Using HAL, I am having some problems. To start, I am trying to read the ID register. I am writing in the address and a dummy byte. The address for the ID register (who am I) is 0xF. The read value of the register should return 32. According to the data sheet (see attached clip for the "read" page), the opcode should be written with the register address, and for a read, the MSB should be 1. On an 8 bit address, this should be 0x80uint8_t address = 0xF | 0x80; //0x8Fassert_CS_low();HAL_SPI_TransmitReceive(&hspi3, &address, &SPIdata,2, HAL_MAX_DELAY); assert_CS_high();printf("return data = %i\n", SPIdata);It returns the "ore'd" address value of 0x8F. Changing the number of bytes to 1 makes no difference.Ditto for configuration register 1 at address 0x20. I have also tried clocking in an additional dummy byte but it does not make a difference. The clock appears to be sending the 2x 8

Use cubemx to generate the project, then use the slider effect to switch screen and everything will run fine in the simulator.But I burned MDK to the hardware and didn't see the slider effect.Is there something wrong with the transplant?

Hi,as now CubeIDE is released, will the development of new features for Truestudio end? Should we use CubeIDE for new projects now, or can we continue using Truestudio and still get new features and bugfixes?Thanks!

I tried to import an Atollic project into STMcubeIDE (which so far doesn't work at all).The import appears to succeed, but the ARM toolchain is not set up correctly and shows "orphaned configuration/toolchain":Has anyone been able to get this to work?Thanks for any tips!Best Regards, Dave
