Hi,I'm studying a way to do OTA FW upgrade for a STM32U5A5 MCU using a LTE modem and SPI Flash external memory. My environment is: STM32CubeIDE v1.16.1 with STM32CubeMX v6.12 and FW_U5 v1.6.0. I'm also using FreeRTOS.I was checking the native Booloa...
Hello,I am trying to communicate with an SDI-12 sensor through my custom STM32L4 pcb. The communication that I am trying to achieve is from a 3.3V microcontroller. Thus, I used the SN74LVC1G240DBVT buffer to convert my UART to SDI-12 data one wire, a...
I have a question regarding the tutorial "Handling multiple TCP clients on STM32H563 with NetX Duo" written by @STea .See https://community.st.com/t5/stm32-mcus/handling-multiple-tcp-clients-on-stm32h563-with-netx-duo/ta-p/695030 In the first section...
Hi, where can I find a working One-Wire protocol? Is there an example provided by STM? I wrote code for a program to detect the temperature from a DS18B20 sensor, but I can’t detect the sensor, even though the debug shows everything is fine. Can some...
While implementing EEPROM emulation on an STM32G0 (although I believe this would apply to all supported families) I have discovered what I believe to be a bug in eeprom_emul.c:Although ConfigureCrc() is called at the beginning of EE_Init to turn on t...
Hello everyone,I have a stm32h735g-dk evm. I am trying to send data through it using the canopennode stack structure. I connected my oscilloscope to the CN18 port. I put the jumper on when 120 ohms is required. I am trying to run the sample code on g...
I'm very beginner of programing and STM. I'd like to make it sound the audio line out with sine wave from STM32H735G-DK. I read the document(UM2679) and understood that SAI and I2C4 are connected to the audio. But I don't know how to use these. Espec...
Hi, I'm playing around with lwIP on my Nucleo-H743ZI and I was able to make ping work, udp/tcp echo and snmp too. But when I enable HTTPd the project doesn't wont do compile I just get a lot of undefined references, I tried to make a new project and ...
I am trying to use H5 as master and UNO(ATmega328p) as slave and transmit data from UNO and receive a character & print it in the COM using USART3. The baud rate I've set for both is 4 MHz. By connecting them together and I can see that the "Tx " LED...
After the device powers on, lwIP works properly. I reboot it once using the code below, and it continues to function correctly. However, if I reboot it a second time with the same code, it stops working. It goes through the PCB initialization, but no...
