Before reading any further, to give you on some insight on the output level of the oscilloscope picture'sthe ~340mV green signal is normal. If you know me I posted a question as to why its 340mV but for sake of simplicity 340mV is normal in this case...
I am very new to use hal_usartTransmit_it because I use only usart_transmit() , which is the blocking mode.I changed all of my transmit() code to transmit_it() for better performance, but after that my ble send message only shows buffer's first lette...
Page 435, the explanation for Bits 28:24 ends with "(see )."This is a real cliff hanger! ;^)
Hi.I am using stm32cubeide version 1.2.0. I am using stm32CubeMx version 5.6.1.The "int _write (int file, char * ptr, int len)" function is not called when the printf ("test") function is called.What did you do:1. Added to Properties ---> c / c ++ ...
Hello!I am trying to read data by QSPI (MCU STM32F722VC). But QSPI always reads out the last value written to DR register by previous operation and does not read data from data lines. For exapmle, DR value is 0xAA from previous write operation. Then ...
In STM32CubeG4 Firmware Package, the G474 digiatal power demo use a FMAC to contol a buck or boost toplogy with one voltage control loop.So if I want to use two loops,one for voltage and other for current loop, could the FMAC(in my opinion,that is j...
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?
