I have an application running on STM32G491 which uses the RTC. There is an external 32768Hz crystal and a backup coin cell battery (I have checked that it is not depleted: 3.12V). There are two issues:Scenario #1: I pull the main battery, wait a bit,...
Other chips have the erratum "Transmit data FIFO is corrupted when a write sequence to the FIFO is interrupted with accesses to certain OTG_HS registers" (eg ES0392 2.25.2 for STM32H743). It isn't listed in the ES0596 rev5 errata for STM32H7Rxx/7Sxx ...
Hello ST support,As a customer working on a project using STM32, I am looking for STM32 development or evaluation boards that feature a socket-based MCU instead of a soldered one. This allows for easy replacement of the microcontroller during the use...
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...
