Resolved! Will a STM32L433CC work with code that was compiled for an STM32L433RC (using mbed) if only common features and pins are used?

I have stm32f103c8t6 I am trying to build ADC drive to read sensor reading I activate interrupt bits control in the preferale registers with other RCC, INVIC bits but the code did not go to ADC_Handeler to read Data register. so what can i do ??

SPI Slave with DMA: How to receive packets of unknown length?

Ok guys. I think I'm slowly turining insane. Someone please help me. I already wasted so many hours on this...I'm currently fighting with getting SPI to work in slave mode with DMA. So let me explain what I'm trying to do.The STM32(F303RE) is connect...

Resolved! Increase PWM Resolution

Hi!Recently, I've been trying to develop a PWM generation module, in a frequency range of 1Hz to 100kHz with a duty cycle step of 1%. I'm using STM32F103C8 Bluepill to do the job.I can implement this just fine. However, in this range I obtain errors ...

Resolved! NVIC_SystemReset not working

I'm using the X-CUBE-SBSFU bootloader on a ST STM32G474VE.Sometimes NVIC_SystemReset is not resetting the controller, only a power reset helps. Any ideas? The string "Image correctly downloaded" i can see everytime!/* System Reboot*/ prin...

STM32F> What is the fastest way to get 16bit data from other components?

Hello, I am using STM4F429ZI with nucleo boardI would like make my own custom board, not a nucleo 32 .My own board has 16-bit ADC component named ABS8584, for better measure adc data.In that case, What is the fastest way to make my CPU(STMF4) bring d...

How to NUCLEO64, UART and Printf output?

Hello,I want to use UART2 on a NUCLEO-L073RZ for printf output but cannotget it to work for the life of me, please help.Context:In this scenario, I need the UART2 output direct from the PA2 / PA3pins on the ST Morpho header (CN10), in other words, no...

Need to get specific number of samples from ADC, what flag to use to indicate when arraystoring samples is full?

Hello all,I need to store 6000 incoming samples from the ADC, analyze these 6000 samples and then store 6000 new samples in the same location and I need to do this repeatedly. I am using HAL_ADC_Start_DMA function to start the channel and I want to u...

STM32L4R9I-DISCO demo projects compilation fails

Hello guys.I dont want to complain, but I think its not normal trying to spend 1 week to compile Demo projects for my STM32L4R9I-DISCO board. I have the github repo below, I've added StemWin libs which are not included due to license problems, but I ...
