Hi guys, I have a project where I need to use STM32 ARM processors I want to be able to program a bare chip of STM32's ARM Microcontrollers on my breadboard. I have a ST link V2 as the programmer. I would like to know what software (for free only)/ap...
Using the STM32F769 Disco, I've enable the external SDRAM using the FMC and can read/write that memory.I also have both SAI audio and microSD interfaces working with DMA, as long as the memory target/destination is internal SRAM. However, DMA transfe...
I want the epoch time in milliseconds (or with a milliseconds field), but the main function that is suggested out there clock_gettime() ends up as an undefined reference. I have also tried functions like gettimeofday() but it always returns zero for ...
I am able to receive data on the USART1 peripheral on the stm32h753-eval board using the character match and RXNE Interrupts. When I configure USART1 peripheral for FIFO mode, I set RXFTCFG to 1/8th in CR3, I enable the FIFOEN in CR1 and the RXFFIE i...
I'm trying to implement an SPI slave using DMA on a NUCLEO-F429ZI board. It basically works but when transactions from the master come too often (about 1ms) I start getting SPI overrun errors (i.e. HAL_SPI_ErrorCallback() is called). I would like to ...
Hi all, I have been tasked with porting existing Atmel SAMD21 code to an STM32F030xC. I am getting a bit hung up on how to implement the DMA transfer functionality. The existing functionality reads from a SPI SRAM chip, and writes to a SPI LCD displa...
Hi everyone, I am new to the community and I am also not very expert on microcontrollers. I own a STM32F407G-DISC1. I was able to write the code for ADC (at least I think), but I don't know how to save the data on the memory. Can anyone tell me how t...
Hello,AN2606 Rev 37 on page 321 writes:For more information regarding the STM32G431xx/441xx option bytes configuration, refer tohe STM32G4 reference manual (RM0433).RM0433 is the STM32H7 reference manual.
Hello, As I am working on analog inputs I require ADC. STM32F334 Nucleo board has 12-bit ADC (2) with 21 channels, I am using ADC1 Channel 1.After programming without applying any input to the pin (PA0) I am getting some values through USART2.Can any...
