Solved

Hi,My application is to copy the content (32-bit Data) in the Memory to PORT ODR each time it detects a Falling Edge. I use DMA1 from TIMER CCP pin. The problem I have is, DMA1 will stop as soon as it complete the transfer and require to re-enabling again. Last time I use STM32F429ZI, I managed to get it running continuously without reenabling. But somehow I can't do it again?Here is my Configuration in the STM32CubeMX for the DMA1:Mode = CircularUse FIFO = DISABLEIncrement Address on Peripheral = DISABLEIncrement Address on Memory = DISABLEData Width = Word (on both Peripheral and Memory)I though by setting DMA mode to Circular then it will run continuously???? But it seems like it is not. Or is it the bugs in the STM32CubeMX?

Hi, We are using LD1117S50 linear regulator for conversion of 9V DC to 5V DC. The datasheet typical application diagram in page 24 suggests to use 10uF electrolytic capacitor. Please let me know whether we can use a 10uF ceramic capacitor at output. Will there be any issues if we use a ceramic 10uF at output instead the Electrolytic one.Thanks,Gopi Krishnan K.

Hi,Does anyone know how to combine western + chinese + japanese fonts into one file for TouchGFX designer?My problem is that I want to use Source Sans Pro font, which does not have chinese, japanese etc. I want to combine Source Han Sans with it, which has chinese and japanese.Thanks!

Hello all, I just bought a ST-LINK-V3 set. Also, I have checked the signal on vcc pin, but there are no voltage on vcc.Is it correct?

Hello,I am trying to create a project with STM32Cube 5.1.0 for NUCLEO-F413ZH. I see only USART 1, 2, 3 and 6 available, none of the UARTs 4, 5, 7, 8, 9 and 10. These UARTs are available if I open a project for STM32F413ZHT, the device used in NUCLEO-F413ZH board. I understand why UART4 would be disabled - its pins PA0/1 are used for other functions in NUCLEO, a user button and RMII_REF_CLK, but UART7 PH6/7 is not occupied.Thank you.

Hi. ST MC Workbench is a PC software which reduces the design effort and time in the STM32 PMSM FOC firmware library configuration. Is there any similar software for positioning?

Hi,I decided on adding the ST25R3911B to a project I work on.I puchase the ST25R3911B-DISCO and for start I would like to "play" with the L4 firmware in order to understand how to manage the ST25R3911B correctly.My problem is that the STSW-ST25R002 (oftware contains the ST25R3911B-DISCO firmware source, which is an USB HID controlled application for STM32L476) is given as a project for Keil. The L4 is not free for use with Keil.Is there a way to get the firmware project on some other free IDE?Thanks.

Hi All,I am trying to set a few GPIO speed to High Speed but I was struct when PC13-15 are only able to set to Low Speed. May I know is this the STM32CubeMx bugs?Or it is the STM32F446RE limitation? Please help.Many Thanks

Touch Designer set pix format as ARGB2222, RGB LCD using LTDC setted pix format as L8. In a simple project ,now it can show correctly. But I imgrate this project with a Touch Designer Demo Project , it can not work correctly. Error show I found uint16_t stride = lcd().framebufferStride();Than deeper in LCD8bpp_ARGB2222.hppthis makes error.How can I fix the error?

I'm trying to use 3 GPIO Pins as a 3-bit ID essentially. Depending on the values read, the uC will configure itself in an appropriate way (1 bin fits all tools essentially). The problem I'm having is that with the eval board the pins are pretty close together, so I can only fit my jumper wires on the top corner pins of each section, vastly limiting the number i can test with.I can get 2 pins that consistently behave correctly when I have the inputs driven/not driven, but the 3rd is always on a pin that constantly be in a HIGH state even at initialization. How do I fix this?int main(void) { /* USER CODE BEGIN 1 */   /* USER CODE END 1 */   /* MCU Configuration--------------------------------------------------------*/   /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init();   /* USER CODE BEGIN Init */ Configure_Card_GPIO_Init(); Configure_Card_Type(gpioSelection); ....   } static void Configure_Card_Type(int gpio_lin

Hello,I am trying to retrieve data from a USB mouse with a STM32F429IGT. (The reason that I typed F4xx in my question is because I tried on other F4 series MCUs)To make sure that my wiring is correct, i connected D+ D- to PA11 and PA12 that are soldered to a microUSB. Plugging it to the computer, I detect it (on the computer), no problem. I also verified that the voltage and current are sufficient when microUSB is not plugged.Also, the HSE is set as well, and I have a crystal oscillator that is set in RCC as Crystal/Ceramic Resonator. I can tell that it is working because I already used USB with this STM32 as a VCOM in device mode.Disconnecting microUSB and the mouse afterwards, I activate USB_OTG_FS as host HID through CubeIDE and try the given example of mouse. However, when I plug the mouse back, nothing happens. It seems that phost->State never changes from the HOST_IDLE state. Further investigation reveals that the function USBH_LL_Connect, that, from my understanding, detects

Posted on June 18, 2017 at 09:21 Hello i have a program on the 32F030f4p6 chip for testing the system clock frequency. It blinks an LED at about 1Hz. the problem is that when i change the PLL multiplier from 2 to 12 the LED still blinks at the same 1Hz. i configured the system clock for 48MHz but it seems to be running at 8MHz. i don't know what i'm doing wrong. #include 'stm32f030x4.h' int main(void) { // sysclock configuration RCC->CR |= RCC_CR_HSION; // 8MHz RCC->CR |= RCC_CR_PLLON; RCC->CFGR &= ~RCC_CFGR_PLLSRC; RCC->CFGR |= RCC_CFGR_PLLSRC_HSI_DIV2; // PLL source = 4MHz RCC->CFGR &= ~RCC_CFGR_PLLMUL; RCC->CFGR |= RCC_CFGR_PLLMUL12; // <-- changing the multiplier has no effect on LED frequency RCC->CFGR &= ~RCC_CFGR_SW; RCC->CFGR |= RCC_CFGR_SW_PLL; // PLL selected as system clock RCC->CFGR &= ~RCC_CFGR_HPRE; RCC->CFGR |= RCC_CFGR_HPRE_DIV1; // ahbclk not divided RCC->CFGR &= ~RCC_CFGR_PPRE; RCC->CFGR &am

Getting stable V-sync and H-sync pulses is critical for clean VGA output. Getting these completely stable on the H743 was difficult and required multiple iterations of different PLL settings. but was possible.On the Nucleo-H7A3ZIQ it has proved completely impossible.V-sync pulses are showing a variability of up to 25uS one to the next. This shouldn't be an issue with displays that use a pixel clock but VGA displays don't and are compromised by the variability in timings of H-Sync and V-Sync.Pity, the 1Mb of internal ram on the H7A3 is enough for a 16-bit 800x600 display without needing external memory but the chip simply isn't usable for this application. :sleepy_face:

Hi there,Variations of this question have been asked before, but I have had no luck so far.I am attempting a very simple setup where I am using SPI to write to a display, where the screen does not talk back. I am using SPI1 on the STM32F091 and cannot get any signals on the CLK and MOSI lines. I am using other GPIO for CS, RST, and DC. I simply want to use the SPI drivers to control the CLK and MOSI, I am doing the rest manually.I used CubeMX to generate code and am still not getting anything. I am sure it is a stupid control bit somewhere that needs to be flipped, but I am at a loss.Here are the generated Init functions:Here is my main. I am simply sending one byte over and over looking for signals on the line.Here is the state of my SPI1 registers right before I transmit over SPI.It seems like the NSS and NSST have caused a lot of problems for people but I have NSS pulse disabled. I admit that I dont have the greatest understanding of what NSS and NSST are doing.Any help is appreciat

Hello,I'm using a STM32G431 MCU ADCs in dual mode. I'm trying to get control of the sampling rate and have found a frustrating issue. I don't need to scan multiple channels. Though the only way to get maximum sampling rate, or to have any control over the sampling rate via prescaler, is to enable scan mode. That would be an acceptable work around, but scan mode introduces its own unwanted artifacts into the samples. In scan mode, though I can get the rate I want, I have the extra data from the scanned channels which I do not need. If I don't use scan mode, the sampling rate is fixed somewhere around 300ksps which is not fast enough. Besides that, slowing the sampling rate is apparently not possible via prescaler in this case.Any ideas how I can do these conversions, without scan mode, while having full control of the adc clock?void MX_ADC1_Init ( void ) {       ADC_MultiModeTypeDef multimode = {0}; ADC_ChannelConfTypeDef sConfig = {0};   hadc1.Instance = ADC1; &n

Hi, for a project, I have designed a PCB with the component LPS25HBT. We want to know if there are some technical recommendations about the sensor's boundary conditions.Will we have to design the cover with some distance between the sensor and the boundary? Some distance or relative distance between the sensor and the cover?If the PCB is embedded in resin must have a minimum distance between the sensor and the resin.Thanks in advance!
