Hi,I seem to behaving an issue getting my STM32F411 PLL to stabilize using the HSI. The code I am using shown below. Setting it to 100MHZ. The code gets stuck in RCC_GetSYSCLKSource() != 0x08 ) continue; . It never returns 8. I had originally got ...
Hi:I use STM32L4P5RG with APS6404L-3SQR to develop GUI.I want use QSPI PSRAM as data memory for GUI.Now, I enable QSPI PSRAM as data memory as follows:1.configure QSPI PSRAM , SPI with NVIC in CubeMX2. add PSRAM (xrw) : ORIGIN = 0x70000000, LENGTH = ...
I am working with am STM32G0B1CB for USB communications, using Zephyr as my OS. I am trying to have multiple CDC ACM serial ports, so that they will show up as /dev/ttyACM0, /dev/ttyACM1... on Linux. Everything seems to work fine if I have only one...
I'm trying to configure the ADC to read to values at a specific time in my system that uses the STM32G474.I have two channels of peak current mode control using the HRTIMER. The outputs are reset from either a comparator event or max duty cycle compa...
Dear ST Support Team,I hope this message finds you well. I am currently working on a project using the STM32WB5MM module, and I am encountering an issue with the BLE stack initialization in my application.I have successfully installed the stm32wb5x_B...
The datasheet suggests load of 20pF .Due to size constraints, I hope to use https://jlcpcb.com/partdetail/318914-CSTNE8M00G550000R0/C341522Most 8Mhz resonators of this size seems to have 33pF
I'm using gpio interrupt inside there void HAL_GPIO_EXTI_Rising_Callback(uint16_t GPIO_Pin){static uint32_t push_time;if(GPIO_Pin == IS_FUSED_Pin){pin_int_now = HAL_GetTick();if(fuze_push_time + DEBOUNCE_INTERVAL < pin_int_now){LED_Green_On();fuze_pu...
Regarding function calls when performing SPI communication in half-duplex mode.We would like to develop a product that performs SPI communication in half-duplex mode.Are there any sample programs in which the slave side transmits and the master side ...
I know that the question will be trivial, however, I do not understand why the instruction uint8_t dataRx[4] = { 1 }; does not initialize all the elements of an array to 0 ... but only the first one:I have programmed little in the last while so I wil...
We are trying to develop a device that uses SPI communication (Receive Only Master).Are there any sample programs for SPI communication (Receive Only Master)?Which should be executed first: "Receive Only Master HAL_SPI_Receive" or "Transmit Only Slav...
