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...
Good afternoon, I'm writing this quick post to know if by any chance someone can help me figure out what is happening with a simple threading project I started on the H7S3L8 board. I'm using ThreadX and NetXDuo, to have a Modbus server on the ETH por...
Hi allI have used CubeMx to create an FMC interface to psram(nonmultiplex) 8-bit data 10-bit addressThe data is valid on the rising edge of the fourth clock To have correct data on the data pins the pointer to write data (psram64) must be a 64-bit po...
Dear all,I am using lwIP over STM32F4 and I would add REST API to my project.I try to understand how to do that, and the only way that I have found is to use CGI. The problem is the reply: I can reply only with a static file present in the SDCARD (th...
