Use SPI with MCU above. Withspi_transmit(0x55);andvoid spi_transmit(uint8_t tx_data) { SPI1->DR= tx_data; while (!(SPI1->SR & SPI_SR_TXE)); }I have 16 SPI clocks. Init was: hspi1.Init.DataSize = SPI_DATASIZE_8BIT; Data on MOSI showing on the fir...
Hello everyone, I'm trying to read four analog signals on my STM32F722RET7 using ADC1 with four consecutive channels and outputting the results over UART.Even though the input voltages remain constant, the ADC readings fluctuate without any change in...
I've been working with the Nucleo STM32H533 and came across a documentation issue. EXTICR1 and EXTICR4 are shown as having the same address on pages 18.6.15 and 18.6.18 of the reference manual. Additionally, in the Special Function Register tab in ST...
Environment: Hardware: NUCLEO-H7S3L8Software: Bootloader: Loaded on internal flashApplication: Loaded on external flash Hi Support Team, We are currently facing an issue with the RTC module, where it fails to initialize and set up when running the a...
Hello, I am using STM32H503 for precise time measurement hence I need to tune the PLL that output frequency compensates the voltage or temperature drift of the HSE crystal.My setup is:- Clock configured as HSE=16, M=, N=337, Nfrac=4096, P=2 which sho...
Hello,I am trying program the flash memory on an STM32f401RE.After successfully programming sector 7 I cannot flash a new application to my board, instead I am met with :Error: ST-LINK error (DEV_TARGET_NOT_HALTED) I can flash new code after a mass e...
I have a custom board with an STM32G473 running at 170MHz. I have the QSPI peripheral running correctly in indirect mode when the pre-scaler has a value of 5 (so ~23MHz) but when I decrease the pre-scaler any further all HAL_QSPI_Receive calls end up...
Hello everyone,I am currently working on a project with the **STM32 B-L475IOT1A2C** and I am looking to implement a BLE *observer* mode to scan for nearby BLE devices. My goal is to retrieve the MAC addresses of the detected devices and analyze the c...
Hello, I’m trying to use the PyOCD library to program an STM32H747 and an STM32U5A9 using .hex or .bin files generated by STM32CubeIDE. So far, I haven’t had much success, and I’d like to know if anyone has experience with this or can offer guidance ...
Hellow In DS10639 P105 [6.3.10 internal clock source characteristics], regarding the measurement conditions of TA (ambient temperature) described in Table 41:Is the measurement method of TA (ambient temperature) based on the temperature of a thermost...
