After successful test on STM32f401RE I moved my design on STM32F071 for cost reasons.I am using UART1 and UART3 first set to 9600 and second set to 115200.But on PC I can see the data only if it is set to 4800 and 57600.At the beginning used interna...
what is the role of voltage regulator in stm32f407vgt6 and how it works..that means already VDD is supplyng 1.8V and again what is the need of suplying 1.2V and how it works i want to know exact operation of it in stm32f407vgt6
Hellow.Mr.Kang system engineer in South Korea.Looking an ADC high performance STM32.The specification is as follows:1~5Msps , 2channel, PGA (if possible)
Hello, I would like to use #define macro in my program to hold application, firmware version and firmware building time. I know i can put these definition into my program directly, and make modification before I compile my program. Could I use GNU C ...
This is the code:#include <stm32f4xx.h>void main(void){//Set up PA5(LED)RCC -> AHB1ENR |= 0x00000001; //enables clock for GPO PAGPIOA -> MODER |= 0x00000400; //PA Pin 5 as GPOGPIOA -> OTYPER |= 0x00000000; //PA Pin 5 as Push/PullGPIOA -> OSPEEDR |= 0...
I have a 10 mhz external clock. I want to generate a phased locked division down to 1hz exclusively with timers. In my current test setup I am generating the 10mhz using TIM1 from the internal clock (this is to simulate the external clock). I am putt...
Hello,I’m using the B-L475E-IOT01A with MbedOS and have the following code:hall_a3 = new AnalogIn(A3);hall_a4 = new AnalogIn(A4);hall_a5 = new AnalogIn(A5);while(true) { printf("Hall A3: %f\n", hall_a3->read()); printf("Hall A4: %f\n", hall_a4-...
Trying to understand how to setup the ID and Mask with Extended ID. I want allow messages with id's 0x1E02xxxx. So 0x1E021234 would be accepted and 0x1E031234 rejected. /*##-2- Configure the CAN Filter ##########################################...
I am considering powering a STM32G4 with a DC-DC Switching Converter. One of the converters I am looking at has a PWM Switching Frequency of 6-MHz, the other 500 kHz. I'd use a hefty inductor and capacitor to filter the current ripple at this PWM fre...
Hello,which points of SDIO (DMA) settings i have to look for if my f_read reads only half but counts full.Example:uint16_t buffer1[1024];f_read(&file,&buffer1[0],1024,&cnt); buffer1 is filled with values to buffer1[511] but variable cnt gives me 10...
