How to store data on non erasable memory of controller during run time.
I am using STM32L442KC part number...And i want to store the 16 byte of data on non erasable memory of controller during runtime...Can i get any reference how to store the data in microcontroller memory???
Fastest way to use UART - sprintf takes up too much time
HiI have to send a large amount of data as a formatted ASCII over UART. The data is read through some terminal software on a PC.I only have 1 wire to do this so it has to be UART.I have a F042K6 STM32 Nucleo and running it at 1500000 baud. Works fine...
Resolved! STM32G071 Nucleo 64 microsecond delay timer
I'm trying to implement a 10 us delay using TIM2. This delay is inside an EXTI interrupt handler.I am not getting a return at the end of 10 us.In the clock configurator, I used the max PLL clock possible, 64 MHz. Is this OK? I don't know what else to...
STM32F405RG weird ADC spikes
Hi I am working on a small project where I need to sample couple of ADC channels.I am using STM32F405RG. ADC1 is running in continuous and scan mode with DMA. I am using ping pong buffers to send ADC data through USART. After gathering some data I pl...
Resolved! Using memcpy to get data from ADC buffer to use elsewhere
Hello,I am trying to use the memcpy function to transfer data from the ADC data buffer to a separate data buffer, but when I call memcpy, only the first 1400 of 6000 samples gets copied, while the remainder of the buffer does not get updated. I notic...
STemWin application for STM32H735G-DK
Hello!Dealing as newbie with STM32 MCUs, I'm focusing on projects of STM32Cube_FW_H7_V1.8.0 packet.As my goal is to develop on STM32H735G-DK, I'd need an application or an example which uses STemWin library. Unfortunately I can't find such a combina...
