Hello STM Community - This post is in reference to the recent STM32U3 workshop webinar. I worked through the rather involved / complicated setup associated with the NFC example. Once the code was generated, 23 errors were returned during compilation....
Hi,I am currently trying to update my STM32L433 on my custom board and I am having some issues with the RDP level 1.When receiving the blank boards (not programmed yet), I use a RPI with OpenOCD and a JTag to update the chip. When I set the RDP level...
Hi everyone,I’m working with an STM32L5 USART and trying to clarify a point about parity vs. MSB-first transmission.From the reference manual (USART parity control / frame formats), when parity is enabled the frame formats are shown as:M=00, PCE=1: S...
I have a situation where a USB endpoint stops working due to a control packet being NAKed in the handshake phase. I've traced the problem down to the STM USB stack setting DCTL.SGONAK = 1 in response to an INCOMPISOOUT event, yet in the case when it ...
Split from: Power Supply for STM32F030 Cortex TSSOP20 VDDA and VDD pin; specifically this post.@TDK wrote:that satisfies the condition. But only the "VDDA >= VDD" condition - it doesn't satisfy the "VDDA must be first" condition. As noted, I suspect ...
I am trying to use SWD for printing using ITM_Sendchar, Printf not calling _write, I tried to put breakpoint and see, But it is not hitting breakpoint
Hi,I am currently working on the firmware of a PCB with an STM32G031K8T6 as the MCU, supplied by a 1.8V voltage.When I enter Stop 1 mode, the consumption of the MCU drops to 100uA, instead of the 7uA stated in the datasheet.The app_stop function is a...
Hi.I am trying to test out a fault handler for our STM32G (right now, the fault handler just tries to determine the location of the code that caused the fault).If I force a fault (divide by zero) in "normal" non-interrupt handler code, I can easily r...
Hi everyone, I’ve been stuck on a CAN communication issue between two boards: STM32F429 Discovery (Classic CAN) STM32H743XIH6 (FDCAN) I’m trying to establish CAN communication between them. Currently, the F4 board can transmit and receive data cor...
I have multiply\accumulate operations that I want to streamline by using the FMAC. For my application I will be loading the X1 buffer by DMA from peripherals and I don’t want to use circular mode. Documentation mentions ‘vector mode’ which matches wh...
