Solved

We are trying to make our first large project with an STM32G473VE MCU in an LQFP-100 package, but there seems to be a discrepancy between the number of accessible ADC input pins for ADC5 between the datasheet (rev 3, last version) and what I can select in CubeMX and what is listed in the STM32G4 manual. Speficically, the datasheet lists only lists the following inputs as alternative functions in table 12:Pin   ADC5_INxPD8   12PD9   13PA8   1PA9   2(found by searching for ADC5_IN)However, in the G4 series reference manual RM0440, pages 392 to 393 (table 69), many more inputs are listed, and these are in agreement with what I can select in STM32CubeMX. For example, I can select ADC5_IN7 through ADC5_IN11 which corresponds to PD10 through PD14 and these pins are indeed physically present.Is the datasheet incomplete and these pins are OK to use, or have I misunderstood something?For my application, it would be very

The STM32F777 has a bullet under Section 2.25 [U(S)ART] :Swappable Tx/Rx pin configurationWhere can I find more detailed information on Swapping the Tx/Rx pin configuration for a UART ?

I use stm32f401's PB4 (NJTRST) pin. I attached 5 V pull-up resistor (5.1k) to PB4. While MCU is in reset mode the voltage on PB4 is 4.26 V. Only after starting the system, the voltage increases to 5 V. In my program I configure PB4 as input without pull-up or pull-down, just input. I couldn't find an explanation in AN4899.Why voltage is 4.26 while reset? Is it because of schmitt trigger?

We have own MP157 based module and it sometimes hangs after NRST during debug. It doesn't respond to JTAG DAP, further NRST pulses doesn't help but NRST_CORE helps. It seems as errata "Incorrect reset of glitch-free kernel clock switch". We tried sw workaround (QSPI clk src=per_ck) but it doesn't help. Thus we tried hw workaround - connect NRST+NRST_CORE (as we use simple smps chip to power core). But the MP1 is stuck in reset - NRST(_CORE) are at GND. Both VDD (1V8) and VCORE (1V2) are up. Once I disconnect NRST from NRST_CORE (while still powered) it immediatelly boots. I also scoped the signals - after power is turned on, NRST_CORE goes up, followed by NRST after 10ms. When connected together, they sit at 0 all the time. Chip revision is 0x2000. Any idea ? Thanks, Martin

My requirement is to 1) Inject ECC error in DFlash2) ECC has to be detected, but there should not be any reset as it occurred in DFlashWhat are the registers to be set for the above steps?Note : I tried sample programs from SPC5Studio* FCCU Test Application and* Flash Test Applicationthose both didn't help me.

Hi,I am working with STM32H743ZIWhen I enable USB DMA, writing enable here : I have 3 bytes of offset in my frames, my frame is supposed to start with aa:55:dd:aa instead of 00:00:00:aa:55:dd:aaIt is fixed when I disable DMA but I want to use itHere is my memory usage :Any parameter I am missing ?Regards,Gabriel

Hi,I can't find the information of  "the USART source clock to providethe Smartcard clock" maximum frequency in document"RM0438Reference manual-STM32L552xx and STM32L562xx advanced Arm®-based32-bit MCUs". Please advise why "STM32CubeIDE 1.5.0"  limit stm32L5 "the USART source clock to providethe Smartcard clock" maximum frequency to 5MHz.Thanks,QiZhang

Dear all,I am struggling with the B-L475e-IOT board and USB. If I use the default initialisation of CubeMX and change the USB device to OTG FS Device only and add the Middleware of the Communication device class I can not get this as recognized device on Win 7 as well as Win 10. The line coding is set within usbd_cdc_if.c as in the USB mooc as follows in CDC_Control_FS and Linecoding is defined and initialized as follows: USBD_CDC_LineCodingTypeDef Linecoding = { 115200, /*baudrate*/ 0x00, /*stop bits-1*/ 0x00, /*parity none*/ 0x08, /*no of bits*/}; case CDC_SET_LINE_CODING: Linecoding.bitrate = (uint32_t)(pbuf[0] | pbuf[1] << 8 |\ pbuf[2] << 16 | pbuf[3] << 24); Linecoding.format = pbuf[4]; Linecoding.paritytype = pbuf[5]; Linecoding.datatype = pbuf[6];   break;   case CDC_GET_LINE_CODING:   pbuf[0] = (uint8_t)(Linecoding.bitrate); pbuf[1] = (uint8_t)(Linecoding.bitrate>>8); pbuf[2] = (uint8_t)(Linecoding.bitrate>>16

A Windows application that writes multiple binary files at once because you have to write multiple binary files to STM32WB at once. Is developing. I can write a binary file to FLASH using CubeProgrammer_API, I can't find a function in CubeProgrammer_API to write a binary file for FUS/RF Stack. Is there another API? Can you tell me if there is one? Also, if you have sample code, could you please tell me?

How can I change the driver to port 4 or how can I install the driver additionally for port 4? *Edited by moderation: please don't mention your email address publicly on this forum*

Upon reading the user manual for the STM32F072, it seems like it is only possible for the slave and master to both read on the first edge or both read on the second edge. However, I am trying to interface with an ASIC in which the ASIC(slave) reads on the 1st clock edge and the STM32 (master) reads on the 2nd clock edge. Is there any way to configure the SPI to work with this setup? The STM32 and ASIC are sending and receiving data at the same time so it seems like there is no way to send data first from the STM32, switch clock phase, and then receive data from the ASIC.

If you set TouchGFX in the stm32f429IG setting, an error appears for the memory below. External SDRAM is in use, FMC setting is done. We drew a background from TouchGFX and loaded that background, which resulted in the above problem in compilation. I don't know which setting is wrong. If there is a problem with SDRAM settings, does this error appear? Who can help you solve this error?

My instance is created in the base file as follows:touchgfx::GraphScroll<50> BlueGraph;And I need to change the capacity of this graph from 50 to 100 to have the line smoother when some event is triggered. Is is possible to change that capacity after setting it in the base file generated ???

In the last 2 days I can't get any results using search engine on the website. For instance, when I type in any STM32H743II code there is only a message like in the picture below. The same situation is for any acronyms or Doc Ids. Is it only a problem on my system (Win 8.1) or browser (FF 84) or is it related to the server?

I'd like to use the STM32L4R9ZG microcontroller along with a HyperRAM memory such as the ISSI IS66WVH8M8BLL. I was reading through the ST application note AN5050 "Octo-SPI interface on STM32 microcontrollers" to familiarize myself with the process. On page six of the app note there is a table called "Table 2. OCTOSPI main features". There is a note associated with this table saying PSRAM is not supported with STM32L4Rxxx. What does this mean? PSRAM is clearly supported with these devices because the STM32L4R9I-EVAL board even has a PSRAM on it. Can someone please explain this to me?Thanks!Rob

HI All,I plan to use STM32L4S7ZITx cpu. I need to work with LCD screen which has parallel interface and connected to FMC. It works fine on demo board but i would like to offload the CPU. But i am not sure if FMC can work with DMA.I checked the following:The RM0432 (i guess it is the right reference manual for this cpu).On page 397 there is a table Tab54 which lists all multiplexer inputs to resources. There is no FMC listed there. So i guess FMC is not supported by DMA.An so it is not possible to offload the CPU from writing long memory chunks to LCD screen or to any memory connected to it.Am I correct?

Hi, this subject has already been treated with other boards in other forums, but libraries and tools have changed since then so i thougth i could open a new question. So i use CAN1 bus in the Discovery STM32F407 in order to share data between 2 discovery. I use a classic transceiver SN65HVD234 from Texas Instruments. I configured the Discovery with CubeMX and used CubeIDE. I'm using the HAL Library.I use the User button to fire an EXTI interuption that call HAL_CAN_AddTxMessage() an writes on the bus. Transmitting data works but not Receiving.The Hardware is working very well as you can see [in the picture][1]. However the end of the frame bothers me a bit, i don't know if this is nominal.Here's what I found using the debugger : The interruption enabled for FIFO0 never fires and the function HAL_CAN_RxFifo0MsgPendingCallback() is never called. So I think the problem comes frome the Filter and its registers that i don't really understand.here is the configuration code : I
