Hello everyone. I am trying to build an i2c multi-drop network with STM32C0316CT6 targets. To achieve that i use the differential buffer PCA9615. Each target (and the master of course) has its own PCA9615, the topology is as shown in the picture bel...
Hi,I am making updates to a custom PCB where I would like to add ADC functionality. My board is powered by batteries and I expect the supply voltage to fluctuate slightly and I need the ADC conversions to be accurate. The reference manual says I can ...
We are using STM32G030C8T6 (LQFP48 package) in a new design and need clarification regarding pin 36: PA14‑BOOT0, which according to the datasheet serves both:SWCLK (Serial Wire Debug clock)BOOT0 (boot mode selection)In our earlier designs using simil...
Hello everyone, I'm having some trouble implementing I3C communication and would like to ask for some help. I am using the NUCLEO-H503RB board as my main controller. For the target devices, I have the NUCLEO-IKS01A3 expansion board and the TSC1641 (C...
Split from STM32G0B0: RM0454 link out-of-date ? - this is a new topic raising issues in the document itself.Hi @Amel NASRI ,Thank you for your quick answer.I have however encountered a few errors in that RM0454 Rev 5 that are different/fixed in RM044...
Hello, I have a nucleo board with STM32H563. I am trying to make a simple application that will take two ADC measurements with regular conversions. I've been going through the refference manual(RM0481 Rev4) and in the ADC overrun chapter on page 1072...
Hi I have been looking into the boot process for stm32n6 and was unclear about a few things. For booting from external flash the steps are as follows 1. build your app's bin file. The app should be built with the vector table at the start and the lin...
Hi everyone, I am facing an issue with CAN communication on STM32F446ZCT6, where the CAN controller frequently enters the Bus-Off state. Hardware Details MCU: STM32F446ZCT6 CAN Transceiver: (TJA1042T) I am working with CAN communication on STM32F4...
I am working on STM32h747 series. I am debugging both CM4 and CM7. After a while, CM4 stops responding and the debug messages shows:"Error in final launch sequence: Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK dev...
Hello, I need to have D-Cache enabled to improve performance of FMC external SDRAM (it's >3x slower without D-Cache enabled). I also want to use I2S for audio. But with D-Cache enabled, I don't get any data from ADC. What can I do to use I2S with D-C...
