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...
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 ...
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...
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...
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...
Dear all,for the past few weeeks, I've been trying to get the STM32H753VIT6 up and running with the USB3320 ULPI interface but I have not been succesfull. First, I have tried to run a CubeMX generated USB CDC example to test the functionality, but t...
Hi,playing around a program found hard fault handler on debugging Can anyone help to proceed that
good morning. since this morning, on my nucleoH755ZIQ I am trying to make work my UART connection. I followed the stm video on YouTube and did as said: connected USART 2 (doesn't USART 1 work?) and then implemented the simple code in the while lo...
Hi,We are using the STM32F446RCT6TR together with a ULPI-PHY in an application to be able to use USB-HS. Is there a controller from ST with which we can dispense with the ULPI-PHY if we use USB-HS + USB-FS with otherwise the same properties as the ST...
Good morning,We designed a LED controller with the STM32C011. We exposed the BOOT0 PIN in our design as followed: Now the first prototypes are potted in without access to the SWD interface and we want to update the firmware via the internal bootloade...
