I am a new user of H563ZI, and I have read the datasheet. I wonder if all pins that can be viewed in cubeIDE can be used as a GPIO pin?For example, as mentioned in the datasheet, PB2 is used as QSPI_CK when solder bridge configurations are not changed. Can I use it as GPIO_OUTPUT pin by just configuring it in cubeIDE without modifying the solder bridges?If not, then the actual numbers of pins that can be used is just as many as the Arduino pins? I am quite confused.

Hi AllI am working on a data logger code. It is basic at the moment.1, set a an ISRTimmer for 1sec.2, When ISR triggered i set DataLoggerFlag.3, Next loop thru main() i test DataLoggerFlag, if set go to a function and read A0, A1 ports and store back into an array i have set up.Every time i run this code it completes 5 successful loops but it always crashes on the 6th loop in the same spot reading A1.The Fault has the same sequence. 1, call A1 read, 2, straight to HardFault_Handler. According to the stack it happens straight after the osKernalStart (see attached pic).I was wondering if this is an ISRtimmer confilct with ADC issue?&n

Hello,I have been using STM USB HOST HID class library to implement the USB keyboard on my STM32F429ZI custom board. I have been able to successfully enumerate the USB keyboard and getting the key pressed on the keyboard using the custom keyread() function in blocking mode as per mentioned below:char keyread(){HID_KEYBD_Info_TypeDef *k_pinfo;char c;while(1){MX_USB_HOST_Process();if(Appli_state == APPLICATION_READY){if(USBH_HID_GetDeviceType(&hUsbHostFS) == HID_KEYBOARD){k_pinfo = USBH_HID_GetKeybdInfo(&hUsbHostFS);if(k_pinfo != NULL){c = USBH_HID_GetASCIICode(k_pinfo);if(c != '\0')return c;}}}}return 0;}For my application I need to implement the RTC updating GLCD screen and if a key is pressed then it update the screen content with the custom character else it shows the RTC data continously. For this I need to detect the Keyboard

Hello everyone.I have to create an arbitrary waveform generator via DAC starting from a lookup array of 32 elements at least with 10bit resolution. However, I must be able to reach frequencies of around 300Khz. I wonder, which evaluation board can I consider?Thank you in advanceAntonio Riccelli

So here is what I am doing, I am using IAR Systems to build my code and generate .s19 file and using an in-house tool to load the .s19 to device (STM32F469IG), after the download is complete the tool sends Jump command or “Go command” (0x21 0xDE) to which the device is sending ACK 0x79 and the tool sends the address 0x08000000  where the vector table is located, to which the device is also sending an ACK 0x79 but the Jump from internal bootloader to user bootloader is not happening. I have verified it multiple times using J-Mem if the memory is written properly and the address locations are correct, I do not see any issue there. I also tried downloading the same .s19 file using “ST Flash Loader Demonstrator” and it works properly, only difference is the ST Flash Loader does not send the “Go command” after download, we had to turn off the BOOT switch and power cycle the device after which the user bootloader worked without any issue. I tried debugging using IAR when the jump doe

Hey guys. I'm trying to learn how to use the stlink programmers and program a nucleo board, without the use of the onboard programmer.I've successfully flashed the board by using the MIPI10 interface and the stlink. The thing is that i we want to make a custom pcb and flash the program by using the stlink. The thing is that i've checked some schematics and the MIPI pins go through the onboard programmer first. Will this method work if i route the mipi pins directly to the cpu on my custom pcb ? If not, what's the best way to flash the cpu ?

Posted on September 02, 2016 at 15:29 Hi everyone, I have a question about an hard fault generated by a line of code. I'm working with a STM32F401RE and Atollic True Studio The line is : sprintf (str, ''PAIR %s\r'' ,BT_deviceTAB[0].BDADDR); the BT_deviceTAB[0].BDADDR type is char tab[13]; and previously filled with a string ended with '\0'The hardfault is :Bus, memory management or usage fault (FORCED)  Attempt to switch to invalid state (INVSTATE) But when i use the following methode i don't have any problems : strcpy (str, ''PAIR '' ); strcpy (name,BT_deviceTabHeadset[BT_number].BDADDR); strcat (str, name); Do you have an explanation of how this functions works. I'm very surpri

I am using the STM32F107VCT6 controller. use STMcubeIDE.I write the code of the UDP Server. but when I change the IP, subnet, and Gateway using TCP and reset the device. I do not get Broadcast info or the udp_recv function not working.void udpServer_init(void){ // UDP Control Block structure struct udp_pcb *upcb;//   struct udp_pcb *upcb;   err_t err;    /* 1. Create a new UDP control block  */   upcb = udp_new();   if(upcb == NULL){   HAL_UART_Transmit(&huart1, "fail\n", 5, 5);

With revision Z of the STM32H563VIT6, which looks to be an older revision of the MCU, we get a HardFault issue in the UCPD library. We noticed the issue with revision Z, but revision X is working as expected (see errata in attachments)!

Hi Everyone,I use SDMMC on my STM32H7 to write data on SD Card. I have several question :- for now I can't reach better rates than 12Mo/s writing, using 32Ko buffers and with the stm32 doing only that. Is that normal? I think I should reach the 25Mo/s announced by the High Speed Sd Card mode.- when the stm32 is running normally, I can't reach better rates than 7.5Mo/s in High Speed SD Card mode. Once again, is it a normal rate or could I do better ?- Those rates are in high speed mode in 3.3V. Should I consider to use a level shifter to write in 1.8V with SDR50 or SDR104 ? Thank you very much !

HiI am facing an odd problem with ADC in conjunction with DMA on STM32L151V8T-A. I can see that it measures all three channels. However, the result of each channel is stored in the first element of my results array (Result[3]). Every time that the callback function is called the results of one out of three channels is stored in Result[0] element. It is as if the memory address is not increasing.Can somebody help?

Hello everyone.I've got a problem running DCMI interface on STM32H7A3 MCU. I'm using NUCLEO-H7A3ZI devboard and OV7670 camera module. Installed the latest CubeIDE and generated code in builtin configurator. Actually I'm using Segger Embedded Studio for development and debug but this does not seem to be a reason.I configured camera module and can confirm that all data and syncro signals are correct. Frame buffer is 153600 bytes size for 320*240 16 bits image. DCMI is able to detect VSYNC and HSYNC pulses and generates interrupts, so framing is working as expected. DMA seems to work as well, I can see data in buffer. The problem is that I receive 1176 bytes of 0x08 and then all zeroes. According to debug info DCMI data register really gets 0x08 and 0x00 bytes, packs them to words and buffers for the further DMA transfer. I'm curios why port is not reading correctly? I tried to cover camera lens and tried set camera to transmit color bars in demo mode. Also play

Working with STM32H743 and STM32CubeIDE 1.14.0.Created a project with FreeRTOS and USB Device CDC.When the program goes into the first vTaskDelay(1000) a hard crash occurs.

Hello,Iam developing RS485 on STM32H753. I use STM32Cube (*.IOC file) for USART configuration (USART with Hardware Flow Control) and everything works perfectly. But last send char by processor is also received in RX buffer. Does anyone know how to prevent this behavior? Thank you for your response.

Hello all,I am currently trying to enable the CRC SPI (CRC-16/CCITT-FALSE) on my project, but I can't make it work. You can found bellow the SPI configuration set on CubeMxHere is the message read back on my logic analyser, in yellow (0x0C52) you'll found the CRC computed by the uC.Ho

I use TIM1 to generate PWM. I want to stop it by the BRK signal. I need to delay the BRK signal so that it works only at the end of the PWM period.The delay will be implemented on TIM3 in OPM mode, and for this I need to synchronize the CNT of both timers without any delay.Is it possible to trigger DMA transmission on the rising edge of the signal entering directly to TI1FP1 TIM3 and copy the CNT from TIM1 to TIM3? regards

I've noticed that the frequencies written in the reference manual are different from the ones used in the HAL.Is there a good reason they are different? Which ones are correct?I attached a screenshot from page 407 of the reference manual.https://www.st.com/resource/en/reference_manual/rm0456-stm32u5-series-armbased-32bit-mcus-stmicroelectronics.pdfAnd a screenshot from github stm32u5 HAL stm32u5xx_ll_utils.cThank you

hello everyone, I am trying to combine a H-bridge-based motor controller and a sensor connected by i2c with stm32g032k8txx. They both work when i run on different microcontrollers, but when I combine them, the sensor is working fine but the PWM of the STM32 gets abnormal, like the output is something like a ramp signal (the motor initially starts at a slow speed and gradually increases to a high speed and stops. After some time, it starts again). Please help me if anyone knows about this problem.

Hi, I am trying to test my fault exceptions. In the event of an exception, I would like to get more information about the problem. In the event of an exception, I am finding the stack pointer and trying to get PC by unwinding the stack. I think the PC would tell me the address where the problem occurred.I have a test code in main() as given below to test my code.

Hi, as advertisedof course , but no : - no UART4 as the datasheet , page 14/200 (false because UFQFPN48 has 4 more pins than LQFP48 ?)- no UART4 as CubeMx : PC10 and PC11 are present , but no UART4I have got a STM32G431CBU6 from an chinese board maker , nice board with amazing MCU tried UART4 as STM32duino's Serial4 : it works , so USART4 is present , officially or not ...(didn't try the handshaking lines)

Posted on August 29, 2014 at 19:35I am trying to setup ADC sampling that is triggered by a Timer. Essentially I want to setup a 1 kHz timer that will trigger an ADC sample every 1 ms, and use DMA to transfer the sample data. I have all the components working separately but I cannot get the ADC to sample on a timer event. In the ADC documentation it lists that events from TIM1 �Timer 1 CC1 event� can be used as triggers to initiate a sampling. I have setup the �EXTEN� and �EXTSEL� fields to use this event, but it does not get triggered by the timer. I have verified that the timer is generating interrupts at 1Khz by setting up an interrupt handler that will manually initiate an ADC sampling via the �SWSTART� bit in the ADC->CR2 register. Using this method I can accomplish the task I want, but it adds delays which are causing me to m

I am working with ADC in STM32G070RB nucleo board. While configuring I have seen SamplingTime common 1 and SamplingTime common 2. What is the difference between these two?  

Microcontroller: STM32L051R8Tx (MSI used as system clock, set to 4.194 MHz) Board: custom design (no Nucleo etc.)The LPTIM1 is clocked by an external LSE (32,768 kHz, +- 10ppm).IDE: Keil uVision V5.36.0.0Compiler: ARM Compiler “Use default compiler Version 5”I scheduled a recurring task with help of LPTIM1 and it’s IRQ. The timer is set to 500ms. The task processing time is around 130ms (measured with help of TIMER21). I observed a latency which is becoming visible over time. After 4080 interrupts (after 34:00 minutes, 4080/2/60) the timer is lagging ~9 seconds (in my application, a few hundred milliseconds wouldn’t be a problem at all). In case this time is getting “lost” evenly per interrupt it would mean >2ms per interrupt. It seems to be unrealistic latency, isn’t it?Secondly, if I replace the task by a delay function of the same tim
