Can the ADC regular channel and injected channel of STM32G4 not be used at the same time? Is this a bug?
I use cubemx (6.0.0) to generate ADC1 configuration code, for example, ADC1 channels 1, 2, and 3 are injection channels, and TIM1 channel 4 is used to trigger, and ADC1’s 4, 5 are Regular channel. STM32F4 can work very well. But STM32G4 does not wor...
Hi, I have a STM32L476VG discovery board and I want to program it with jtag communication and PE micro multilink universal programmer and IAR IDE.
I have installed a firmware of ARM in PE programmer and I have connected NJRST, JTDI, JTMS, JTCK, JTDO, NRST of programmer to the board then I Chose PE as debugging driver in IAR IDE.but can not communicate with MCU.I have checked the wires connectiv...
CAN is not initialised when RTC enabled
I am designing the application that uses both CAN interface and RTC. I noticed some weired behaviour that I need to fix somehow. Directly after upload the application starts and CAN working properly. With battery present (there is power on VBAT) if I...
Low Level I2C readByte out of sync
Hello,I am trying to implement a low level I2C readbyte function, currently trying to read out register 0x41 (TEMP_H) and 0x42 (TEMP_L) from an MPU9250. The issue is that when I debug print the values, it seems that TEMP_H_Buffer appears to have the ...
Resolved! DMA1_Channel7_IRQHandler doesn't get called
HiI am trying to do a simple USART communication via DMA (LL Drivers). I want to send two chars to my STM32F103 from my PC which are received by DMA. In the DMA RX transfer complete callback I want to send some text string, also via DMA back to the s...
use timer to decode pulse/step + direction signal?
STM32 timers can decode quadrature signals.STM32 timers can count external pulses.can STM32 timers do pulse counting AND take counting direction from a second external input?my current solution (on an STM32F303CB/CC, but also F103) is to let the time...
