I'm using STM32F070CBT at 8mhz with almost all pins active (used for GPIOs, PWM, SPI,I2C,etc) , i'm using a timer to enter stop mode with low power regulator and waking up using GPIO external event, after waking up i checked that PWMs and GPIOs are s...
I want to capture images larger than 0xFFFF via DCMI using double buffering with two GPDMA1 linked list nodes. As guidance, I'm following the DCMI_ContinuousCap_EmbeddedSynchMode example. However, it seems that the DCMI_DMAXferCplt function is writte...
Over in the post https://community.st.com/t5/stm32-mcus-embedded-software/stm32u5-fracn-not-working/m-p/691980 an issue was raised with the delay necessary to ensure live updates of the FRAC N PLL register. The reference manual for the STM32U5 has be...
Hi everyone,We’re working with the STM32H730 microcontroller and have a test setup for displaying content on a screen using LTDC. The test currently fills a buffer in external RAM, which is configured on internal flash memory. The result is as expect...
#Intention : Simultaneous measurement of 8 frequencies ( Squre wave, upto 1.5 Mhz ).I have tested this youtube tutorial by Controllerstech on my board Nucleo-STM32U545REQ. First of all, i could not setup the board with HSE oscillator according to th...
I am trying to flash a chip on a PCB. Right now I just have it toggle an LED. Sometimes it connects, but does not toggle, only stays lit. After power cycling, it does not even light up, it just stays off. Is there something i am missing, perhaps in t...
Hello, I am trying to write and read from stm32f105 to an eeprom 93AA46A, using Full-Duplex Master. To write into the eeprom, I am using following code:void EEPROM_WriteEnable(void) { uint8_t cmd = EEPROM_CMD_WRITE_ENABLE; //0x98 EEPROM_CS_H...
Hi, Please share pointers on interfacing 32Bits RAM along with STM32H750XB MCU with QUAD SPI External Memory and 8 MB Frame Buffer RAM on STM32H750XBRAM - IS42S32400TFT USED - 1024x600 at 24 bpp and or 1024x800 at 16 bpp at 60 + FPSAre These Set...
Posted on February 11, 2015 at 13:01Hi, Does anyone familer with Low cost microcontroller with 16bits ADC (below 1.5$) ? Thanks
I used the code below but not working , did you find the solution ? void SetPinTristate(GPIO_TypeDef *GPIOx, uint16_t GPIO_Pin) { GPIO_InitTypeDef GPIO_InitStruct = {0}; GPIO_InitStruct.Pin = GPIO_Pin; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; // Swi...
