I send the temperature value on a serial interface.In the live watch of the IAR tool, I can see the same correct value than the one sent on the serial interface.The problem occurs after a power-down/power-up of my board, like if something is not init...
Hi all,I'm currently working on a project using the STM32H723 interface with SDRAM IS42S16400J. After booting up, I have to read a large JSON file [2MB] from flash into SDRAM then parse it to get the information. I wonder if I could allocating dynami...
Hi,I try to jump from Bootloader to my main program using this function:void jumpToMainProgram(){ uint32_t topOfStack = (*(uint32_t *)0x8008200ul); HAL_RCC_DeInit(); // deinit clocks // reset all periphals __HAL_RCC_AHB_FORCE_RESET(); __HA...
Hi there i cant get a real data from ADS1227L01. In debug mode i see the value 0xFFFFFF.Q1: If anyone used ADS127L01 can they send me librarys for comparison ? Q2: Im using 3.75MBits/s Baund Rate is it enough for 24 bit data?
i have some question in stm32H743 about fmc ,i want to write a 16bit-date to external sram(16bit width), i find , when i read a word(16bit),the NWE and NE chaged 4 times seems with address self-add,but i want one! what bothers me? the code generated...
Hi, I've got a bit of an odd question but I'm hoping someone will be able to help or at least point me in the direction of some further information.I am currently looking at a project where we need around 10 PWM outputs so we were looking at using th...
I have worked with f3 series and in user manual there is shown what peripherals are connected to each DMA channel. For example 4 peripherals are connected to one channel, that means I have to configure only one peripheral to use that DMA channel to s...
So I'm having this weird bug I can't seem to figure out.I'm trying to connect two stm32f4 discovery boards through SPI.The master is sending out a SS signal I want to use to synchronize with the slave.However for some reason before I send out a messa...
I had some wrong bytes when transferring data over SPI, so I tried to clean the DCache. But I get a hard fault if I do this:I'm using the NUCLEO-H723ZG board.
Hi everyone,I have followed the tutorial from ST to set the external loader :https://www.youtube.com/watch?v=XqCq0xtQmbIhttps://github.com/STMicroelectronics/stm32-external-loader/tree/contribHere's my HW config :I use the same QSPI (MX25L51245G) tha...
