I'm working on various examples using rider7. However, sometimes I encounter unexplained errors. The issue is that the hex file doesn't change. It seems like there might be garbage values in the hex file, as nothing works. Even if I change the main.c...
Resolved! Problems with H723ZG and ADC with DMA after integrating ETH and LWIP.
Dear STMicroelectronics community, My name is John Peterson, and I am trying to develop on the NUCLEO-H723ZG board. I am having a hard time figuring out how to make ADC with DMA and ETH/LWIP work concurrently. If I create a new STM32 project with my ...
Resolved! STM32F411 cant get PLL to stabilize using HSI
Hi,I seem to behaving an issue getting my STM32F411 PLL to stabilize using the HSI. The code I am using shown below. Setting it to 100MHZ. The code gets stuck in RCC_GetSYSCLKSource() != 0x08 ) continue; . It never returns 8. I had originally got ...
Resolved! How to enable QSPI PSRAM as data memory
Hi:I use STM32L4P5RG with APS6404L-3SQR to develop GUI.I want use QSPI PSRAM as data memory for GUI.Now, I enable QSPI PSRAM as data memory as follows:1.configure QSPI PSRAM , SPI with NVIC in CubeMX2. add PSRAM (xrw) : ORIGIN = 0x70000000, LENGTH = ...
