Update STM32 Firmware from external flash
Hello,I am designing an embedded system with these parts:A Low-Power STM32F091RCT6 microcontrollerEC25 LTE/GPRS moduleA 16 Mbit serial flash (W25Q128JV)After each reset, the microcontroller should check if a new version of firmware is available. If s...
SPI DMA variable data length
Hi,I'm working with stm32H743zi (Nucleo-144) , I have a device that transmitting data via SPI to my stm32H7, the problem is that the device sending data with a variable length that I have no idea about it and there is no way to receive the length bef...
Resolved! STM32H743 - SPI stops working after a while and doesn't create Clocks
Hi all,I have a complex system with several STM32H743 processors, 1 Master, 6 Slave processors. The Master sequentially reads data from all Slaves via Interrupt handling. SPI clock speed is 16 MHz, access to data reads (108 Bytes each Read) every 10 ...
Resolved! How to correctly set up FDCAN Message RAM Start Addresses?
How do I have to set the configuration of the FDCAN Message RAM Start Adresses correctly in order to use 2 CANFDs simultaneously?Is there an example which shows a correct initialisation? The default samples initialize all start Adresses to 0, but thi...
SMT32F3 Differential ADC
Dear friends,I'm setting a differential ADC input for my application.The Positive voltage connects to ADC1_IN1 and the Negative connects to ADC1_IN2.When I reading the 0V, the result I get is 1583 values of ADC (It is the raw data, I did not convert ...
