OSPI Clock Configuration on STM32U5A9J-DK
Hi, I am currently working on configuring the OSPI clock for the STM32U5A9J-DK board, and I have some questions regarding the configuration. From my understanding, based on the Clock Configuration tab in the STM32CubeIDE (.ioc file), the clock going ...
DMA latency
I working through issues on an STM32G4 where at times I'm not getting the reaction time from the DMA that I would like. I read AN2548, and it is a very helpful resource. However, I'm seeing slightly worse response times than AN2548 would suggest, and...
Resolved! STM32C031C6, m0+, how to create a 32-bit timer with TIM1 and TIM3?
I would like to use TIM1 and TIM3 as a performance counter to evaluate my software application. Is there an example of how to configure TIM1 and TIM3 to chain their 16-bit counters to create a 32-bit counter?From reading the reference manual, I can ...
STM32H5 GPDMA Timer circular buffering interrupt issue
Hi, I am using linked list mode for circular buffering DMA with Timer1 in burst mode. The expectation is that after 300 transfer from memory to timer 1 CCR register, the DMA should start again with the buffer. To do that I need to use Half Trasfer in...
Resolved! STMH7 UART interrupt does not trigger on serial Rx from a STM32F103CB (OpenCM9.04)
I am testing Rx handler logic on a STM32H7 based board. Pins PD0/PD1 are set as Rx/Tx (huart4) with Global Interrupt set. The uart is setup to interrupt on Idle...HAL_UARTEx_ReceiveToIdle_DMA(_uart, _JoyRxData, BROADCAST_CMD_SIZE);and the interrupt i...
How to store data in flash memory of STM32F401CCU6?
My STM32F401CCU6 has 256K flash memory, and I want to use it to store some data. Trying to create a user kept pausing the program at the hardfault handler when I tried debugging. Where am I going wrong? Are there any good resources for this microcont...
