I have a system in which the power source to the CAN transceiver interfaced to the on-chip CAN peripheral is common between multiple MCU's vis-a-vis a connector. I have experienced issues wherein if the connection is broken and then re-connected betw...
I am beginner in using STM32 boards I am working with stm32f411re board with that I will use sim900a gsm module for internet connectivity and then mqtt protocol to send data to AWS cloud. So, when I am using paho mqtt library paho.mqtt.embedded-c/MQT...
Hi there,I am configuring HRTIM TIMD to generate PWM which works as expected, roughly following the Synchronous Buck Converter example for the DPOW1 eval board (my target is the nucleo64).I use LL API calls instead of HAL calls for my project. I ha...
hello everyone, I have a problem, I have a custom PCB with an STM32L011, I have a sim800l module connected, I send the AT commands via LPUART1 and I want the response on UART2, but as an answer I got AAAAAAAAAAA and after a while Call Ready,Call Read...
Trying to work with the STM32F411 USB OTG peripheral and compiling with Segger Embedded Studio, I'm having trouble clearing out the USB interrupts.The USB peripheral has IRQ bits that are write-1 to clear. As can be seen in the image below, the brea...
If this is not the forum for this kind of question, please let know where to post.I have a few STM32H7 MCUs which I bought once when they suddenly, momentarily became available during the ... Great Chip Shortage.78 units of 100-pin STM32H7VIT6 13 uni...
I am working on an STM32G483VET6 in my own hardware. I am trying to use TIM16 CH1 (pin PE0) to generate a PWM signal which drives a sounder. I believe that in early tests I verified that it was working but I was probably messing around manually with ...
Hello everyone, I am working with STM32 Nucleo-H743ZI2 microcontroller. I configured the card's Ethernet and Lwip settings by following the steps in this link. https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-...
Hello, I am developing an application using a Nucleo-H723ZG Board in Simulink. I want to read sensor data using I2C and then sending the information to an dSpace Control System using UDP. As I am most knowladgebale using Simulink Code Generation I ch...
I am currently working on using the USB3320 ULPI PHY with the STM32H7B0VBT6. After reading the STM32 reference manual, I noticed that it mentions special attention should be paid to the hold time when operating at 1.8V.Additionally, I came across a f...
