The chip is H743. After performing a erase operation on a page and resetting it, when I read the page again, the debug page shows that the erased page is 0xAA. As long as I read it, I will enter hardfault. Have you ever encountered a big shot,
I would like to ask about the current load. I expect to use three sets of SDADC, SPI, and USART, all of which will use DMA for transfer and operate at a frequency of 11000HZ. The clock will use an external 12M crystal oscillator. I estimate from offi...
Hi everyone,I’ve designed a schematic based on the STM32G0B1CE microcontroller. Since there’s no official development board available for this specific MCU, I used the schematic of the STM32G0B1RE Nucleo board as a reference, along with the STM32G0B1...
I've been trying to find examples of the STM32N6 using the internal SMPS however, other than trying to reverse engineer the Nucleo or Discovery boards, there doesn't seem to be much literature available showing this.Ideally (for cost and board layout...
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...
