Hello, I just designed an electronic card using the STM32G474QET6TR. Just a day before receiving the card I realised I had made a mistake on the routing. I want to use SPI2 to driver 2 MAX4896ETP+ that are daisy chained.As per the MAX datasheet, to d...
According to erratum 2.22.10 of STM32H562xx/563xx/573xx in RMII 10MHz mode packets should be accepted when both dribble and CRC error is flagged. According to Reference Manual RM0481 Rev4 Table 692 dribble bit is valid in MII mode only. Pls. clarify ...
Hello, I'm trying to use the repeat counter of the 2D GPDMA peripheral. However, when I configure this with CubeMX and run it, I can see that the BRC register is always at zero, while the BNDT register is set to the correct value. I've stepped throug...
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...
