Dear All,I have been working on project to develop an HMI for vehicle for prototype purpose I am using MI0283QT-9A TFT display in SPI mode want it to work with my customized board using STM32F103CBT6. Currently I my using ILI9341 drivers available on...
I am working on an STM32 device with TrustZone enabled, and I am using the RTC with backup domain powered by VBAT. My RTC is initially configured while VDD is present, and after power-off, the time is supposed to be retained using VBAT.When I use the...
I want to use stm32f103rct6 inner RTC, I write some code as below to active RTC, But I found I couldn't set DBP bit of PWR_CR reg to 1, __HAL_RCC_PWR_CLK_ENABLE(); __HAL_RCC_BKP_CLK_ENABLE(); LL_PWR_EnableBkUpAccess();when I debug the re...
Hardware: EVLSERVO1 official motor evaluation boardIn the "ENC Calc Angle" function, there is a step to perform bitwise AND operation 0x7ffffff on TIM ->CNT, multiply it by the unsigned 32-bit maximum value divided by the polar logarithm. Its left va...
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 ...
Hi. I have a newly purchased NUCLEO-U575ZI-Q. I followed the instructions here to install the toolchain on Windows 11:https://www.st.com/en/evaluation-tools/nucleo-u575zi-q.html#documentationhttps://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step1_T...
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 ...
