Hello, Datasheet DS14791 Rev 4 has a note on page 161 stating that PCB and pin capacitance for the OSC_IN/OSC_OUT Interface can be assumed as 4 pF combined.I qoute: "For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors,d...
Hi,I need to understand better how the "HAL_SAI_Receive_DMA(&hsai_BlockB1,ADC_Buffer,CodecBuffer_Size)" works.I've a codec connected to the SAI 1 of a STMH723 MPU and I implemented a Ping-Pong routine to acquire and send the data to the Codec; two Ca...
Hello,i use a STM32G051K6 with LL Drivers and want to implement I2C. But all the time it sends Slave ID, 0x01, Byte 1, 2 and so on. Here i Call 0x38 Slave ID: And here all Data:And this my Code: LL_I2C_TransmitData8(I2C1, 0x00); LL_I2C_HandleT...
Hello, dear community!I have a problem with adding more than one button to my STM32 Button Box / joystick with buttons. I am using USB HID.I made it as simple as possible - only two buttons, simplest descriptor. The problem may be trivial, but after ...
Hi,Has anyone used the STM32H750B-DK on-board eMMC, 4GB memory.I have been unable to find an example and it is a big job to write something from scratch.I am assuming that it would use the SDMMC1 peripheral in MMC 8 Bit mode and that you would need t...
Hi everyone,I'm having an issue with HSE bypass mode on the STM32G0B1RCT6 and hoping someone here has seen something similar.The HSE randomly won't start in bypass mode. I've tried two different oscillators - the S2D8.000000B20F30T and an OT32258MJBA...
Hello, I'm using stm32u5 series MCU and I need help on below.1. System clock I've configured to 24Mhz and how do I set my ADC clock to sample at 20Khz2. Without DMA, single channel data collection I'm able to do but not able to do for multiple channe...
Hello,I've noticed an issue when using the RTC to try to calculate subseconds. I am using the NUCLEO-U575ZI-Q board, with a new project with these settings:with this clock configuration: I've added this code to the while loop: /* Infinite loop */ ...
Hello,We have a product that works well with the STM32U585AIIXQ rev X.In the latest batch, some boards have the STM32U585AIIXQ rev W, and the application no longer works (the power consumption is as expected).The application starts by transmitting so...
Hello, In our project we are planning to use STM32H743BIT6 uC, we are using USB for flashing the firmware and to download the logs, not at the same time, if we connect DM & DP lines from uC PA11 & PA12 pins to USB microAB connector DM & DP lines, wil...
