The company has a very old product with LPC2468. I need a replacement from STM32. Please give me a suggestion. The device is powered by 2 AA batteries, has a black-white LCD, and a micro-USB port for connection to PC. I want to keep the same power co...
Hi all, how are you?. I'm doing a program where I need to send several separated messages over the serial port using the UART 1 of a STM32F401VE after receiven a specific message through the serial port too, right now I'm capable of send the first rs...
Hello,I am experiencing some weird patterns on one of the 3 SPI buses on CLK and MOSI.This project was initially developed off a nucleo H743ZI3. I am using 3 SPI ports, 2 of which I have no problem with. These 2 are used to communicate with another M...
How to measure the time from __asm__("nop") on STM32F730 using 216 MHz clock? I did try to check it using osciloscope without success. The time is bigger than 1/216 MHz.
Hello - I have been working with the l051 for 2+ years now on a product, using i2c-1 as slave to outside world and i2c-2 as master for local board downstream devices. while my interrupt-driven code "works," I continue to have bugs filed about both ma...
Hello, I am having a problem. I am using STM32F411CE and NRF24L01 module. I try to sample sound using ADC and then I send it using RF to another uC. I sample a simple sine wave at 48kHz with 16 bit resolution using IT. I send 32 bytes at one time usi...
I need to configure STM32G473 ADC in 16-bit mode, Currently i configured it in 12 - bit mode it works fine but as per my application i need 16-bit resolution. As datasheet indicates it is possible to configure 16-bit mode by oversampling, but is ther...

Hello, we are currently porting some code from STM32F070 to STM32F446. In the original code, we used to use a generic byte from the option bytes to keep some flags between two resets, without using one page of the onboard flash memory, using somethin...
I want to control servo movement with potentiometer. I'm using ADC and getting the pot value. But i don't know how to control the pwm with this value. What should i use?Thanks in advance.
