I am using the NUCLEO-L552ZE-Q board to check the cycle counts for some of the CMSIS DSP library functions and getting unexpected results. I am comparing against ST AN4841 benchmarks and getting over 2.5 times more cycles than the Cortex-M4 in the a...
Good afternoonConfigured TIM1 of a F070CBT6 to drive 3 PWM channels on PA8/PA) and PA10....PA9 and PA10 work fine..only for channel 1 I don't see any output..furthermore it seems to be floating as when touching with a finger the attached 7406 driver ...
Using STM32F030 Discovery board.I read the ADC channels including the internal temperature sensor and vrefint.#define TEMP30_CAL_ADDR ((uint16_t*) ((uint32_t) 0x1FFFF7B8)) #define VREF_INT_ADDR ((uint16_t*) ((uint32_t) 0x1FFFF7BA))The calibration val...
I've been slowly learning how to develop apps using STM32L4R9 and STM32F4xx MCUs. I just went through a really painful experience trying to develop an app that talks to a UART device and logs data to the SD card on the STM32L4R9-Discovery board that...
The access time of the FMC is not the whole equation, I need to include the delays introduced by having to go across domains and buses. Back to back reads or writes would shine more light on this for me. Or possibly a read followed by write so that ...
Hi community,I'm developing on STM32F7, it accesses the external device via FMC.Then it can read the external device's register, but it cannot write to the register.The external device expects EXTMODE ModeA timing like the following figure. Reference...
Hello,RM0394 in 16.3 ADC implementation mentions "SMPPLUS control" for ADC2 on STM32L412. I do not find any other expalantion.Thanks
I'm new with the STM32F767ZI (Nucleo board) and tried to write a SPI driver with DMA access.It works so far, but I have some stupid things on my log, I can't interprete. Is anybody there, who knows what there is going wrong?I'd like to send three byt...
Hello,I'm a new new member and user of STM32 microcontrollers. I've just started using a bluepill STM32F103C8T6 microcontroller and I'm trying to set up a simple SPI communication.At the moment I do not have slaves, only a master (the STM32), and I'm...
Hi,If I am starting with 120 MHz system clock and want the master timer to generate a 60 MHz PWM waveform and I want the second timer to generate an in-phase 8 MHz PWM waveform I must clock the second timer with 120 MHz (as 60 MHz isn't divisible by ...
