STM32 MCUs Products

Hi @Issamos Hope You doing well . we are started new design using STM32U575VIT6Q this controller, we have some doubts regarding the SPI line, we searched in the STM32cubemx in that we cannot able to find the octa spi pins, Can you pls share me the Standard SPI lines pins and Octa SPI pins ,thanks 

Heyho,I have a super-stable TCP-audio-streaming server on a H733 here, using custom ETH driver and lwIP, no OS.But I recently found that in a struct which is used for handling / storing the TCP connection, the variable to store the port number "u16Port" (used in lwIP's tcp_bind() to set the TCP port) changes as soon as data is transmitted.It's really crazy: u16Port has the init value before and after the connection is accepted, but as soon as data is transmitted, it changes all the time (checked via UART and http REST). When data transfer stops, it keeps the latest wrong value, after TCP connection is closed,  u16Port has the init value again.All other values in the struct do NOT change and their values make sense.I have tried to set the struct to volatile, use another memory area, align, but still changing.I just checked it with the STM32CubeIDE debugger under Live Expressions

Hello All, I am facing a strange situationI have an ISR function1 that is triggered on Falling / Rising Edge of a GPIO pin This function1 according to the state of variable will either start TIMER2 and stop TIMER3 and the way around.TIMER2 & 3 have also ISR. But before starting/stopping TIMER, it needs to update memory variable that will be used by TIMER ISR.The issue is that the variable is effectively updated in memory after the start of TIMER and a few (100 CPU) cycles are needed to get the proper value.This is time critical and I need the value of wrBitPos to be 0 and wrBitCounter to be set a the right value before the first timer iteration. How can I fix this ?I use the volatile declaration for variable.void function1(){ TIM3->DIER &= ~TIM_DIER_CC4IE; // disable CC4 interrupt TIM3->CCER &= ~TIM_CCER_CC4E; // disable CC4 output

Hi All, I'm using an STM32F1 with a 240x240 LCD screen that comunicates with the micro by SPI (with DMA). The screen uses the ST7789 driver (I supose it is not important). I'm working with RGB565 color format.The problem that I have is, for example, when I'm using the ST7789_Fill_Color(YELLOW); the SPI uses the DMA and the LCD shoul be yellow but it's not. If yellow is 0b1111 1111 1110 0000 the DMA only sends to SPI the LSB (0b0000 0000 1110 0000) witch is a wrong color.When I do the same without DMA it work's fine!The DMA is configures this way:I tried every configuration possible but nothing works. My question is why the DMA only graps

Hi,I have a problem with the ADC2 calibration on STM32H743VIT6(V). I use ADC1 and ADC2 in dual mode(Regular simultaneous mode). On some boards the ADC2 calibartion doesn't work. (The ADCAL-Bit in ADC_CR is not cleard after start).On the boards where I have the problem with the ADC2 calibration, when I change the dual mode to simultaneous mode + Regular simultaneous mode the calibration of ADC2 works.I don't unstertand this bevaior. What is the problem of ADC2 calibration on some controllers in Regular simultaneous mode. 

Hi,  I want to count the time that an incoming level signal is high for. To achieve this I setup Timer 15 as a Gated Mode Slave, which has it's counter counting while the trigger input is high. The trigger input is the Filtered Timer 15 Channel 1. For some reason when I connect my signal to my input Timer. Nothing Happens. The signal on the IO Pin TIM 15 CH1  is a 2V square Wave.My own software seems correct. I then moved to Hal to see if I can achieve it.  I've tried to use HAL to achieve this without any luck here is my HAL software.Uploaded is the main and IOC fileI am working on the STM32G071Thanks 

I’d like to use the NUCLEO-N657X0-Q board together with the B-CAMS-IMX camera to output video to a computer as a webcam using CSI → DCMIPP → UVC.However, since all the CSI and UVC examples are provided only for the STM32N6570-DK, I’m having difficulty creating this setup. Although there are some examples for the NUCLEO-N657X0-Q, I’m struggling to understand the code. Is there a simple project or example that uses only CSI – DCMIPP – UVC?

Hello everyone,I'm working on a custom board with an STM32H563 and using CubeMX, HAL, and ThreadX.I am trying to receive variable-length UART data via DMA using HAL_UARTEx_ReceiveToIdle_DMA(). My problem is that the HAL_UARTEx_RxEventCallback never triggers for the HAL_UART_RXEVENT_IDLE event. It only triggers for HAL_UART_RXEVENT_HT (Half Transfer) and HAL_UART_RXEVENT_TC (Transfer Complete).SetupFunction Call: HAL_UARTEx_ReceiveToIdle_DMA()RX Buffer Size: 1000 bytesDMA Mode: CircularData Source: A peripheral sends packets of variable size (approx. 2048 - 4096 bytes) at 1,000,000 bits/s.Idle Time: There is a guaranteed idle time of > 45ms between packets

I have several an 2 F401RE boards connected to my PCs and getting data by the Virtual Communication Port.Unfortunately when installing a new board on the PC, I ve seen that my 2 boards were declared by Windows with the COM portCOM port 7, 9 and 10 are allocated by Windows to others boards I am under the impression that there is a bug in the Virtual COM driver that do not authorize to declare a virtual COM Port beyond COM10.Is there a fix or a workaround. Otherwise Is it possible to reuse an COM port, for instance the COM 9. Is there a procedure to unsintall the COM9 in order to use for my new boardFinally, I would have connected in parallel, on my system, 3 boards with COM8, COM0 and COM10  

Hello,I'm here on H75x. I'm looking for portable way to do a timeout check via timer.Here, I want a timeout IRQ if UART receive DMA hangs up.First I setup a OnePulse timer in Cube. It generates the following code:if (HAL_TIM_Base_Init(&htim6) != HAL_OK) { Error_Handler(); } if (HAL_TIM_OnePulse_Init(&htim6, TIM_OPMODE_SINGLE) != HAL_OK) { Error_Handler(); }The second init function does almost the same as the first but activates the OneShot mode which stops the counter immediately if IRQ is fired.I was looking for a suitable HAL function to setup the timeou

Hi,I’m using an STM32L052 with LQFP32 package, VDD = 1,8V.According to the datasheet:“VDD_USB = 1.65 to 3.6V: external power supply for USB transceiver, USB_DM (PA11) and USB_DP (PA12). To guarantee a correct voltage level for USB communication VDD_USB must be above 3.0V. If USB is not used this pin must be tied to VDD or VSS. On packages without VDD_USB pin, VDD_USB voltage is internally connected to VDDvoltage”Since in the LQFP32 package VDD_USB is internally connected to VDD, it is therefore powered at 1,8V in my design.As expected, the USB interface does not operate when I connect the board to a PC and risk of damage because D+ and D- tied to 1,8VCould you please confirm tha

Hi, I am using a STM32F411CEU6. I am trying to make the One Pulse Mode of TIM1 start every time TIM2 has counted its ARR. However, I don't seem to really understand what the relevancy of the ARR of TIM1 is when having  TIM2 controlling the start(except if it is longer than TIM2 ARR i guess). Now I have 90MHz on both APB1 and APB2 and the PSC of both TIM1 and TIM2 is 90. I was following an example online where he sat the ARR of TIM1 to 50000 and ARR of TIM2 to 60000. The Pulse of TIM1 was 10000. From my understanding when I am running in output compare mode PWM1, TIM1 should start every 60ms and have a ON time of 10ms. Instead I see an ON time of 20ms and a period of 60ms. However when I change the ARR of TIM1 this ON time also changes. Is there something I am missing completely here? (I also have to change the OCMODE of TIM1 to PWM1 because it does not seem to be an option in MX)Thanks in advance!

Hello, I want to use LTDC on the STM32H743VIT6 microcontroller, but when I enable this peripheral in CUBEMX, it does not activate correctly. For example, the pins for B are from B3-B7, while they should be from B0-B4, and the same goes for R, G.  

Hello, I bought STM32H743XIH6 board and first tried to program it with FTDI programmer and STM32CubeProgrammer. It looks like the serial interface detects the board correctly as I can see it in the STM32CubeProgrammer but fails at a read attempt of 0x080000000 address with error message like "error occured during read at address 0x08000". Next, I read that I need ST-LINK to over come UART problem so I did. I purchased ST-Link V2 and gave it a try:22:33:27 : UR connection mode is defined with the HWrst reset mode22:33:27 : UR connection mode is defined with the HWrst reset mode22:33:27 : ST-LINK SN : 37FF71064E57343691A3134322:33:27 : ST-LINK FW : V2J46S722:33:27 : Board : --22:33:27 : Voltage : 3.26V22:33:27 : SWD freq : 4000 KHz22:33:27 : Connect mode: Normal22:33:27 : Reset mode : Hardware reset22:33:27 : Device ID : 0x45022:33:27 : Revision ID : Rev V22:33:27 : U

I'm designing a circuit to convert sensor values ​​to ADC using the STM32U073MC (LQFP-80).Unfortunately, I'm new to the STM32U0 series.I read the RM0503(Rev 4) Reference manual(page 427) and found that the OPAMP1_VOUT can be connected to ADC1_IN8.However, I checked the datasheet's(DS14548 - Rev 2 - March 2024) port table(page 32/Table 12. STM32U073x8/B/C pin/ball definition) and it seems to be connected to ADC1_IN7.

Hello, I am fighting about a week to enable USB-PD comms on my STM32G0B1 MCU and even chat GPT literally told me - he don't have a solution ( shock, a?) One last try before I quit, is to try 1.5.0 package version but I can see in cube MX  only 1.6.0 the earliest. (attached). Repository has 1.5.0 folder and zip. Any ideas?

For H7, the kernel clock limit are given in Table 61 Kernel clock distribution overview as shown inhttps://community.st.com/t5/stm32cubemx-mcus/stm32h745-fdcan-clock-frequency/td-p/83540I do not find a similar table for U5 in the most recent datasheets and reference manual. If I did not look carefully enough, any hint to find it is welcome. Otherwise ST should  consider adding like for H7.

The STM32H753 Reference Manual (RM0433) covers the integrated flash memory inside the microcontroller. It does not say why type of flash is integrated though (NOR or NAND). Is it possible to share what type of flash it is?

In STM32G474 UART4 pin no PC11(Rx) is 5 Volt tolerant . If I pull up this pin to +5V with 4.7kOhms then it will affect life or operation of microcontroller? please Suggest.

Hello everyI want to increase STM32G473 FDCAN Tx buffer and Rx buffer size,In STM32G473 datasheet    >> "A 3-Kbyte message RAM memory implements filters, receive FIFOs, receive buffers, transmit event FIFOs, transmit buffers. This message RAM is shared between the threeFDCAN modules."In my project, I used three FDCAN（FDCAN1 FDCAN2 FDCAN3），However, after testing, if there is no delay, each FDCAN can only send a maximum of 3 data.This seems to match the SRAMCAN_TFQ_NBR parameter.But when I modified this parameter, the data sent became very strange, and the CAN analyzer could not receive normal data. Does anyone know how to increase the tx buffer size of FDcan? Besides this, I would also like to know how to increase the size of the rx bufferIf you have any questions, please feel free to discuss with us，Thanks！

Hi,  Has anyone managed to Trigger Timer 2(Combined PWM Mode, One-Pulse) with Internal Trigger 3(ITR3). The TIM14 OC1 waveform is the trigger. When I run Timer 14 in output compare mode, with an active level on match between Couner and CCR1. I cannot trigger the Timer nothing happens. If I go an manually trigger the timer, everything works.  Here is my Software to setup Timer 2 in Combined PWM Mode 2, on channel 2, One-Pulse Mode. 

I am able to do a line reset, enter into JTAG_SWD mode and read the SWD_ID. I want to know how to configure the core registers for SWD initialization process. 

I can't decipher the silkscreen markings on this chip. Could you please help me confirm?This chip looks like it's from ST, but I didn't see the ST logo. I suspect it's an abbreviation for STM32G473ME, but I can't confirm it, and the chip's datasheet doesn't provide detailed information on device markings.

I'm working with the STM32U5G9, trying to configure access to internal RAM blocks with TrustZone enabled.  Part of this configuration uses the HAL_GTZC_MPCBB_ConfigMem() function from stm32u5xx_hal_gtzc.c from STM32CubeU5 v1.7.0.I see in that function a comment indicating: /* limitation: code not portable with memory > 512K */ pMPCBB_desc->AttributeConfig.MPCBB_LockConfig_array[0] = READ_REG(mpcbb_ptr->CFGLOCKR1);but the STM32U5G9 has several internal SRAM blocks with size over 512K: Is TrustZone MPCBB control not fully supported by STMCubeU5 for the STM32U5Gx pr
