The need I have is to count the encoder pulses on each front of the two channels (x4) always incrementing the counter independantly on the encoder direction and only have a tag on the direction changes.I configured the TIM2 as encoder input (as shown...
Hi, On a STM32L476 MCU, I use many timers with various synchronization / outputs combination. I've two problems still remaining :On TIM3, the Channel 4 Output compare mode TOOGLE do not seems to work correctly (the GPIO do not toogle, it simply goes ...
i am making a J1939 data logger with STM32F405RGT. The vehicle's J1939 is transmitting data on 250kbps, but when i set250kbps in mcu it doesnot show any data on uart terminal , but when i set 500kbps in mcu then it shows some data on UART terminal. I...
Hello.I want to run the ADC to transfer data through the DMA to the RAM buffer.What did you do:void initADC(void) { DMAMUX1_Channel0->CCR = (9 << DMAMUX_CxCR_DMAREQ_ID_Pos); DMA1_Stream0->CR &= ~DMA_SxCR_EN; while(DMA1_Stream0->CR & DMA_SxCR_E...
Hello,it seems that some attendees have issues with logging to the Teams meeting and they receive following error message:AADSTS50020: User account '<user_email>' from identity provider 'live.com' does not exist in tenant '<STMicroelectronics or othe...
We have PCB assemblies built that contain STM324L7 with 1M and 2M flash memory. How can we determine the flash memory size using a JTAG connection (e.g. by reading a register value)?
Does anyone know if its possible to have a dedicated area memory of the Cortex to load dynamic functions during runtime? Something like an external C compiled function and send the binary through a communication interface (serial,i2c,etc) to the Micr...
I am trying to use DAC Channel 1 on STM32H7 with DMA to control the ramp-up of a PA. The DAC must always be driven (enabled). A ramp-up sequence is written at the start of a burst and a ramp-down at the end of the burst.The FIFO error flag is set on ...
Hi all,Thanks in advance for your time, appreciate it!!My doubt is over the microcontroller STM32H743ZI. It has 3 ADC modules integrated. As far as I understand, each module has a Sample and Hold, thus ADCs 1 and 2 can be coupled in order to work in ...
