STM32L073 I2C not sending 9th clock pulse

Hi,I have an STM32L073 communicating with an IS31FL3246 LED driver over I2C. Occasionally the MCU will not send the 9th clock pulse and therefore locks the bus. (As shown in the picture the analog signal has a valid waveform without much noise)Before...

Can the storage in the HyperRAM be automated for some variables at compilation on a STM32H735G-DK Board?

Hello,I am working on the SM32H735G-DK Board and I would like to automate the storage in the HyperRAM for some variables by using the OCTOSPI interface. I have followed the AN5050 Application note about the OCTOSPI Interface to configure the OCTOSPI ...

I can't complete the download and debug of my STM32F401 Nucleo-64 MCU on IAR on Windows 11 because i get the following error "Failed the search for probes, ensure that the USB drivers are installed".

I have found that under the windows 11 control panel the ST-Link driver is not correctly recognized. Please see the attached picture about this. There were no problems of this sort on windows 10, it only occured on windows 11. I tried to reinstall th...

I can't solve the ADC error descibed in ES0251 - Rev 5 - December 2021. STM32L051R8T

Dear allI use the ADC of an STM32L051. According to the errata, the first measurement is not accurate if the ADC has been idle more than 0.5ms. I can observe the effect if I poll a certain channel.In my application I want to convert 5 Channels every ...

STM32F4 Simulator mode violation error !

hello , I have this problem when im using simulator mode , when i run through my code , first its stepping through in a very vague manner , also its giving me this on the command line error 65 : access violation at 0x40023C00 : no 'read' permissioner...

Hello, I am currently working on STM32f205 using Keil uvision. I am getting an undefined instruction fault.

The core registers are as follows :R0 = 0 R1 = 0 R2 = 40005400 R3 = 70000 R12 = 802d8f9 LR = 800a88b PC = 8001ba0 PSR = 100002f- FSR/FAR: CFSR = 10000 HFSR = 40000000 DFSR = 0 AFSR = 0By disassembling the code, I found that the faulty instruction as ...

the max frequency of STM32G030x6x8 series CORE

hi,everyone,I'm a new user of the SMT32 MCU, now i'm looking up the datasheet of STM32G030x6/x8 series, In this article， the Frequency of CORE is described to reach up 64MHz on PAGE 1, but on PAGE 11, Figure 11 block diagram, fmax = 56MHz, so what ...

I want to send serial data in Manchester code using STM32H7. Could anyone please tell me the solution? Or if you know an IC part that can be converted to Manchester code externally, please introduce it.

How long does it take to call the interrupt function of comparator?

I tested with NUCLEO-F303ZE (72Mhz clock).I checked the time when comparator makes interrupt as below ------------------------------------------------------------------------------------void COMP7_IRQHandler(void){ DRV_GPIO_Port->BSRR = (uint32_t)DRV...
