Hello, I'm using two H533 Nucleo Boards and I'm trying to establish an I3C communication between them. There are no specific examples for this protocol using two of these boards, instead there are only examples for a sensor which I don't have. So, I ...
I have purchased STM32F103c8t6 microcontrollers from three different vendors, but they are behaving differently.I am working on CAN, and on the microcontrollers from one vendor, it is working properly. But on the microcontrollers from other two vendo...
Hello, I am currently in the midst of developing a super simple system to create a varying load. It's basically to resistors in series with a transistor in parallel of the second resistor. The transistor is driven by a PWM signal to bypass the secon...
Hello all, i got a firmware configuration problem, basically im using USB in FS modem and when i plug in the usb to the pc what happens is that sometimes it can be recognized and i see a network disk called ''boot'' but most of times it cant be reco...
Hi, I found a pretty interesting issue while developing an STM32H7 Series MCU.And I tried many things to figure out the cause but failed. T^T If you have experienced similar symptoms or know anything about them, I hope we can discuss it together here...
All control signals seem to be good: `DEN`, `VSYNC`, `HSYNC`, `CLK`. but pixel signals (R0 ~ R7, G0 ~ G7, B0 ~ B7) are always low. 1) DEN. 2) HSYNC. 3) VSYNC. 4) CLKalthough control signals correctly work, no pixel data lanes do not. Code that genera...
Hi,The STM32H7RSxx TRM specifies, for ETH_MACMDIOAR, the following CSR values: Bits 11:8 CR[3:0]: CSR Clock RangeThe CSR Clock Range selection determines the frequency of the MDC clock according tothe CSR clock frequency (eth_hclk):0000: MDC clock ...
I have the following function to verify that a full flash sector is erased but the code never seems to exit this function and I believe it gets stuck at the point where I dereference the address value. What could be the issue?static bool check_sector...
Hello,I am trying to implement Modbus protocol in an efficient way. Untill now I have implemented everhting with UART interuot based Transmission and recption. Now I would like to implement with DMA to offload controller from much neavy lifting. For ...
I wanted to use the HDP (Hardware Debug Port) peripheral on the STM32N6 MCU (Nucleo N6 board), but CubeMX does not generate the MX_HDP_Init() function for it and does not initialize the peripheral either.Based on the reference manual, I tried configu...
