Hey guys,Kinda pulling my hair out as to why the pull up resistor is not kicking in? I am expecting when the MCU boots up to see a nice high signal on PA4, but nothing. I am not sure what I am doing wrong. if I write a 0x01 into ODR it then pulls up,...
I am trying to implement a code that can read the velocity of a DC motor with built in encoder. I am using STM32 F446RE and a CQrobot motor equipped with an Hall encoder.. specifications below:http://www.cqrobot.wiki/index.php/DC_Gearmotor_SKU:_CQR37...
I'm using a STM32H745 MCU, with two processors, one of which is an M7. With the M7 I have problems with the DMA, I have seen that it is a very discussed topic on the internet, where there are many solutions, but I still have some doubts: I would like...
I am trying to set up a CANBUS connection between two STM32L4 Microcontrollers and while having has been setup correctly and none of the microcontrollers are sending error messages I cannot seem to get a Receive message from either CAN transceiver.Th...
Hello,I was experimenting with the L432KC board. While connected to the computer everything worked fine, but as soon as I tried to use an external power supply everything stopped working. More specifically the board's led LD1 slowly flashes when conn...
I need to sample a continuous analog stream of 2 ramp signals using the STM32WB15CC MCU. The ramps are generated by another IC but are disciplined by the rising edge of a PWM generated by TIM1. The analog inputs are connected to ADC_IN5 and ADC_IN7 r...
Hi,I have been working with STM ADC’s from quite a long time. I had used STM32F373 and F4 series MCU ADC’s earlier for my applications. As, now my application requires huge amount of RAM, memory and computation speed I have shifted to STM32H743 MCU ....
Hi,I use DMA for transfer data from external flash memory to DAC for playing sounds - in 8 bits mode like that:1) TIM6 gives impulses to DMA_1 - which transmit dummy byte to external flash in 8 khz intervals (Fsampling of sound). External flash alw...
Hi,I am using ST25DV64KC micro for NFC communication interfaced with SAML micro controller. I have kept the setting for GPO signal as I should two pulses for every RF read/write session, first one indicating RF field is active and another one indicat...
Hello,I'm currently using the ADC on the NUCLEO-H743ZI2 board to sample a low frequency sine wave signal.The ADC is configured to DMA, circular buffer, continuous sampling mode and oversampling ratio of 4 with 2 bits shift.When I set the ADC sampling...
