Getting string by UART Receive
Hi everyone.I am sending string data from PC and I want it get with UART of STM32F1xx but as you know I can only have 1 character.For example I am sending "234" as a string from PC, but I can see only ascii character of only 2 (ascii code of 2 is 50)...
Resolved! Problem with multiple HRTIMER synced operation due to missing HRTIMER updates
We found a weird behavior on the STM32F334 device:The requirement is to have 2 HRTIMER's which are locked in phase to generate output PWM's.Currently we use HRTIMER1A and HRTIMER1B for the PWM's. The master timer is used to generate reset on MST per...
hi, i am new to stm32, i want to use modbus in my stm32f103 to read , read and write the commands in both register mode and coil mode. I searched for modbus libraries but i found nothing .
Can anyone help me were can i find the modbus libraries and how to implement in my code.Thank you

I am using UART4 from STM32F072VB with 9600 baudrate on inetrrupt basis.uint8_t p[2] = {0,0}; // array to store data received on uart temporarystoring uart receive data in this array according to my program requirement.uint8_t led_ip_cmd[5][16];//arr...
How can I send and receive RTSP and RTP packets over UDP on STM32H743?
I am using STM32H743 MCU and sending camera data on Ethernet using UDP protocol. Now I want to send data using RTSP and RTP protocol to send the data. How can I modify the present UDP packet to make it RTSP as library for RTSP is not available.
STM32L011F4 drooping supply rail where as STM32L031F6 doesn't on the same board
Hey,I am using STM32L011F4 with an external ADC & DAC connected via SPI bus.I have 3.3V & 5V rails on the board, 5V regulator (internal to an IC) can only supply 10mA max current.Controller when unprogrammed droops the 3.3V & 5V rail. If powered exte...
Any DLMS/COSEM library available for STM32 tagets?
I've seen an old application note on ST website about a DLMS/COSEM library.Is this code still downloadeable?
USART2 SR register issue
Dear community,I plan to use the USART2 of my STM32F407VE board for an IrDA communication (8N1, 115200 Baud @ 8 MHz fPCLK). I started with initializing my USART2 periphery on the register level (I don't use STM32CubeIDE). This seems to work fine. How...
Resolved! STM32 external DAC sine wave problem.
Hi!I would like to make a wav. player using STM32 microcontroller. My first step was to generate a sine wave using STM32F103C8T6, SPI interface and external DAC MCP4921. However, it's not working.I attach the schematic of my device.I wrote 2 versions...
