Resolved! C++ for firmware development - how do I get started?
I have decided to implement my firmware in C++ on an STM32 Arm Cortex M4 microcontroller. However, I find it difficult to get started. I lack good examples and learning tools.Does anyone know good examples of firmware in C++?
Resolved! Is it possible to Connect an STM32H745ZI-Q(after configuring the CAN Engine) to a CAN Bus operated at 24 Volts?
Hello ST Community and Experts, I have an STM32STM32H745ZI and i have programmed it to send and receive some CAN messages from an other STM32 F446RE Nucleo Board. I would like to know if i can use STM32STM32H745ZI to connect to a different CAN Busno...
Resolved! Executing code with stm32f469 from SDRAM
Hi, My board consists of stm32f469 that interfaces SDRAM via FMC. I want to execute code from SDRAM. Code is loaded from internal flash to SDRAM at address 0xc0000000. But running the code from this region causes hard-fault. Is there a restriction wi...
Resolved! How to use ADC multi channel (stm32f042g6) - Read 2 or more sensors data (in Different channel) ?
* I want to know how to read 2 or more sensors data in (stm32f042g6) through ADC,*stm32f042g6-> This is my controller has only one ADC (with 9 channels),Eg: Suppose Channel No :1 (temp-sensor) Channel No :2 (gas-sensor) connected,*In this scenario ho...
Resolved! How to detect STM32F417 MCU reset source
I try implement a function to detect how the MCU start from, reset from watchdog or hardfault or recycle power.Watchdog reset, if the code goes to dead loop, it will trigger WD, but I have no good idea how to capture it.Recycle power, I can use PVD_I...
STM32F7: Is it possible to generate PWM signal based on external freq source (not clock src!) using timer's external input trigger?
Hello,I've not much experience with all STM timer modes. I have a DDS-based freq source which produces meander wave. On base of this src I want to produce PWM signal using STM timer. As I understand, a regular way to do it is to pass the DDS src as e...
Power Supply Scheme capacitor STM32F030
Hello, the datasheet of STM32F030C8 say to use 100nF and 4,7uF capacitor. I have a doubt about the type of this 4,7uF capacitor. I have to use a ceramic, tantalum ou electrolytic? If I use a ceramic, this need a specific model or any ceramic capacito...
NucleoL476 and FFT ARm lib
hello all, I try to use the arm lib to make a FFt but I d'ont understand it well and so I can't. I need some help on it.first, I make a acquisition of a signal (form a generator).the signal is at 30KHz. I sample with the STM32 at 1MHz. I use a DMA to...
Reliably reading the CAN bus Rx FIFO overrun flag
Hi all:I have an STM32F407 and I am trying to implement a CAN bus software driver.I want to know if there has been a Rx FIFO overrun, which would mean that the firmware is too slow and is not seeing all received messages. Each hardware Rx FIFO can on...
