Actually i got the project on modbus but i am trying to code without using libraries but i am not getting expected result. can anyone help me with this and what extra line i need to add in my code please.Thank you
Hello,I'm some confused how external interrupt is working with GPIO. If PA3 and PB3 are both configured as external interrupt, and assume the two interrupts are not coming simultaneously, how to determine which PIN generates the interrupt when EXTI3 ...
I've been using the following two bit timings for a CAN bus speed of 500K on the STM32F103. I was just wondering which is better? Does it make any difference? Is there another preferred option? Thanks a lot for any insight. //(1+9+8)*4 = 72 //1+9+...
the target type is stm32f072, firstly the master transmit data success, slave receive data ok; should i need to disable spi ,enable BIDIOE in slave. but the slave can't transmit data, how to solve it?
Hello Everybody,I am using the STM32H743ZI chip with STM32CubeIde. I have been having success with my code running in debug mode with the debugger attached. however when I power off the board and start it up there is a problem when the program start ...
Hello, my question implies that there is no value for TS_CAL2 available for the STM32G070, although its reference manual RM0454 describes it on page 292 (14.9 Temperature sensor and internal reference voltage: Reading the temperature). Since there is...
Dear all,I need geneate an interruption about 5Mhz to access to an external device using FMC. I am trying to use a Timer to generate that interrupt but I do not get the results I expect. On STM32F429 and STM32CubeIDE, I config timer 10 with the foll...
I'm getting value from LM35 sensor and i am converting it to celcius. Then I am trying to send it to serial port via UART but i couldn't do it. What codes should i use to convert data to bits. Thanks.
D20 separates Field GND from PGND. Why?Is it recommended for the CLT-01 or the VNI8200XP or both?What is the probable drawback of connecting the 2 nets without this diode protection?
I dont know much about all this and I want to learn how to change functions in the GPIO registers. do You use the Cube IDE ? and are there any good tutorials on how to change pin functions ?
