Hello,I am having an issue with DMA1 getting "stuck" during operation. While DMA1 is stuck, DMA2 continues to run without any issues. I realize that this is likely a race somewhere, however I am hoping for any insight into how or why the DMA controll...
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...
Device : STM32F072RBT6 DiscoveryDebugger: ST-LinkV2Core : ARM Cortex M0SDK : NilIDE : VSCode with ARM GCC CompilerHi,We are trying to do profiling on our device. We are planning to use GNU gprof.We are trying the solution given in the below l...
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...
