On STM32G473, why would the ADC readings be lower than the calculation says they should be?
We are running the STM32G473 micro and are using an ADC channel to read the various bus voltages (3.3v, 5v, and 24v) as well as motor currents. All the ADC readings are lower than they should be, but not by the same percentage.I am pasting some samp...
How to set up the adc sampling time.
Hi,I am using ADC of STM32H743ZI which is configured as 16 bit, ADC clock =36.5MHz,Tsampling=1.5cycles in continuous conversion mode . I am using DMA technique to collect the data using a buffer size of 4096 in circular mode.The input is sine wave o...
UART information is shifted by 1 byte when I connect my STM32G474RE directly to my PC and use a terminal program to send information to control things. It fixes itself after resetting the board.
For example, if I send 1000, it will be received as 0100 on the STM board. I send what I received in the Rxcallback function. My program doesn't work, so I know this is the case. This issue stops after I hit the RESET switch on my board. Now, my iss...
Resolved! How is STM32 (drone) configuration software interfaced with source code?
Drone firmware like betaflight or cleanflight come with GUI configurator software that allow settings/variables to be changed using the UI and then built uploaded onto an STM32 MCU all through the config software. I know the configuration software us...
Resolved! Availability of FDCAN peripheral on port C pins of STM32G0B1RE
Hi,Parsing the datasheet DS13560 of the STM32G0B1RE device, there is a discrepency between table 12, where some pins of port C have the FDCAN peripheral listed as alternate function, however it is not present in table 13.On the contrary, PE0 and PE1 ...
ssd1327 oled display interfacing with stm32
Hi have been working on the interfacing of ssd1327 with stm32 microcontroller, i am just trying to print a pixel on the display but I could not display it. my code is as follows WRITECOMMAND(0xae); // WRITECOMMAND(0x15); WRITECOMMAND(0x00); WRITECOMM...
Utilizing discover board STM32F407 with FPU
Hello! I am utilizing discover board STM32F407 with FPU , The board is ARM cortex M-4 based. I want to use FPU to quick the process of conducting exponent calculations and Floating point. I have set down all peripheral drivers that are required for a...
Hi, I'm developing a motor project using stm32f429. TIM2's status register is unnormal.
Hi, I'm developing a motor project using stm32f429. But my pro can hit the HAL_TIM_IRQHandler() interrupt function but the status register is not normal when tim2 capture XORed input signal. The TI2's CC1IF is set when hit the interrupt function but ...
Resolved! unexpected waveform in Examples/OPAMP/OPAMP_PGA/ in G4 package
I try to learn how to use OPAMP by testing the example code Examples/OPAMP/OPAMP_PGA/.The MCU board is Nucleo-G431RB.This is the case of OPAMP_PGA_GAIN_2_OR_MINUS_1: blue line is output by DAC and red is by OPAMP. My 1st question: why the amplified s...
