Hi,I have a custom board with an STM32L031C6 and I'm trying to read the internal temperature. The board is battery powered at about 2.6V and the vdda is the same.If I read the ADC channel with vrefint, it returns a value of about 850, which, when pas...
Hi I am looking into using STM32F446RCTx for my design, which includes 2 x USB FS 2.0 (1 x Host + 1 x Device). Hence need to provide an external HSE. I want to use an Oscillator, meaning I setup the HSE as "Bypass Clock Source" .With this setup I pla...
Hello there I am struggling with receiving interrupts on my microcontroller project. I am currently developing a CAN bus logging device; the following code therefore sets up the CAN peripheral in silent mode. I test my device in a CAN network with tw...
HelloYes here we go again… I’m again busy with the implementation of PTP slave inside STM32H7, based on this GitHub: https://github.com/hasseb/stm32h7_ptpdI tried to port this to my own project based on STM32H7, I changed what was mentioned in the re...
There is this errata for STM32G0B12.2.10 Prefetch failure when branching across flash memory banksDescriptionIn rare cases, the code prefetch may fail upon branching and function calls across flash memory banks,regardless of the DUAL_BANK and nSWAP_B...
Split from this thread. Actually, I have jitter in TIM1 PWM. Is there any way to decrease jitter?
we are observing with the RTC (Real Time Clock) on the STM32L496ZG in our project. kindly help us to resolve this . The code gets stuck on power-on . Below are the details and what we have tried so far:1. Summary of the IssueAfter a full powering on...
Hi! I'm working on a Power Delivery Sink using an STM32G484RETx MCU. I managed to get SPR Power Delivery working without any issues, but I'm having trouble handling the EPR handshake.I'm using the latest USB-PD library from ST's GitHub:https://github...
Hello, I expect this to be flagged before but couldnt find during search. Is Table 116 for the stm32f43xx on page 768 missing registers for CRYP_K2LR / CRYP_K2RR at offset 0x30? TIA
Hi everyoneI use STM32G030. I'm gonna set the clock system to HSE on the External crystal, but I couldn't find the proper RCC_OCS_OUT.What are the MCU's crystal correct pins?Please help me set the correct pinout.Thank you
