Hello,I designed a custom board with an STM32H723ZGT6.It worked fine, then, long story short, this happened:I accidentally connected the VCAP pins (Vcore voltage) to 3.3V, then switched the board on. After about 2...3 seconds I realised something is ...
I want to communicate with delta HMI (slave) and STM32 as master device.Now master(HMI) send data to slave(laptop) I received inverted data. Slave id is 01 but I received 7F from hmiIt works well with non inverted data.So how can I communicate b...
I am porting the code from ATMega128 to STM32F103 for faster throughput to WIZNET W5500 using the WebServer.C for ATMega128. I am using the HAL coding as I am new to STM32. While the throughput is faster than the ATMega128 but I need more speed. Cha...
I have set up a project in a cube. SPI + DMA. When the mcu sends data from the stack, the DMA works fine and activity is visible on the pins. But if allocate an array of data in bss as static or global, then nothing happens on the pins. The program r...
Hi, xSemaphoreTake is not working properly(getting held at taskENTER_CRITICAL) after existing sleep mode. Before entering sleep mode using HAL_PWR_EnterSLEEPMode the value of portNVIC_INT_CTRL_REG is 4194304. After exiting from sleep mode using an ex...
Hello,I'm now spent about three weeks with trying to set up a custom board with the M7-Core of a STM32H745BIT6 to work with an ILI9341-controlled display via SPI.Interfacing the ILI and writing a bitmap to the display even with 50Mhz SPI Clock (with ...
I have a customized bootloader app which needs to update itself.I think if linking all the code to RAM and run code in RAM, then it should able to update itself as it does not require accessing flash.my thought is changing all section with flash (>FL...
