Hi there,I'm starting to use the NUCLEO-H533RE board to evaluate the H5 device family.RM0481 has some errors on the PLL configuration:Fig.55 on page 461 shows a VCO range 0 between 128 and 560 MHz, but the description of bit 5 of register PLL1CFGR (p...
Hello people,I have been developing a firmware to be used in the stm32g051. One of the features is the ability to respon to request to get information from the uC. I used dma for the uart1 tx and rx. I was happily developing and testing the new feat...
Hello folks,I am investigating the Video Encoder on the STM32N6 and have been working through the reference project (VENC_SDCard_ThreadX).The user manual (RM0486) is very vague on detailing the Video Encoder, and lists over 100 pages of registers whi...
I'm writing a UART driver for NUCLEO-F103RB and I followed all steps in the book "Bare-metal embedded C programming" and advices from Gemini but still can't see the receiving output from my PC.How can I fix this?Other parts than UART work without pro...
Hi, On STM32G071CBU6, when PB15 is used as CC2 with DBCC2 shorted to CC2, does the ROM bootloader ever drive PB15 as SPI2_MOSI, or does the CC/dead-battery own the CC2 pin and that path always takes priority? This detail is critical for our design be...
Hi everyone!I figure out that Type III Format Interface Descriptor is generated automatically on STM32L476RG, and this use encoder format to transmit audio (Not PCM). Frame size vary an do mot match PCM packet sizes, meaning that transmitting raw PC...
Hi, I am using STM32U083 for one of our project. We are using the I2C peripheral to communicate with NFC dynamic tag through I2C.In STM32U0 datasheet I found that the I2C pins SCL and SDA are 5V tolerent pins.We need the I2C to work independently of ...
I am working with the Nucleo-STM32F753ZI board and using the internal OPAMP peripheral. The supply is 3.3 V, and according to the datasheet the OPAMP output should swing close to the rails, but in my case the maximum output I can get is only around 2...
Hello,I'm trying to test FW update over I2C using RPI as host and STM32L432 nucleo board as slave on port I2C1 which according AN2606 (table 152) should be available. I've connected 4.7k pullups on PA6 + PA7 pins and perform NRST to 0 and BOOT0 to 1 ...
Hi everyone,I’m working on an STM32F4-based project and facing inconsistent I2C communication stability between the MCU and an external sensor. The issue appears mainly when the sensor performs clock stretching, which causes the STM32 to miss data or...
