The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi, I’m working on a board with an STM32L072RZ. I have and external clock source connected to PH0. And I want to use PH1 as GPIO. According to the Reference Manual RM0376 at section 9.3.13 this should be possible. But in section 7.2.1, the document a...
I have unknown length of data to be received on UART, and It is continuous bulk of data so which is the better way to use UART, I have configured it with DMA but It is accepting defined bytes only.Could you provide best solution which is good for thi...
Data bits are shifted on second SPI session (BSY bit stay high at the end of data transfer in slave mode) We are using STM32L462VET6, and initialize SPI2 in full duplex slave mode (CPOL=1, CPHA=2-edges) with software NSS and baudrate 960 kHz with HCL...
I am using the board B-L475E-IOT01A1. I want to send data via UDP broadcast.I have a udp server running on a host at port 1100I use the following set of AT commands to open a Client Connection after initializing the WiFi module and connecting it to a...
debug a program in the sram, the current is 29 uA, how to down to 8uA or lower ?i dont know how to disable flash/eeprom or other peripheral
I am going to use RTC in my application to generate time stamps. I am currently using Nucelo - L412KB evaluation module. Do I need to connect any pins or add any components? Where can I find this information?
I have STM32F407 that is communicating with TFT lcd over SPI. What I am seeing with Logic Analyzer doesnt match what I am sending. I cant see the pattern, but data is consistent, so its probably some setting that is off. I tried all combinations of C...
Hi,I'm using the FLASH_Write function in order to save a table in a specific address. Once it is saved correctly I reset the board and try to change another address with the same function.The problem is that the flash_write function works at the firs...
When I used the STM32L412KB as an I2C slave. when there only one slave on the bus, all the function works well. but if there hastwo devices on the bus and continue to access one slave device, the non-addressed I2C slave will damage the SDA bus. I cap...
