STM32U575 ADC sampling issue
HelloI use a STM32U575 develop board to do the ADC sampling. The inject signal is 10mV RMS with 1.648V bias voltageHowever, from the sampling result, there is a obviously break point in the result.Could you help explain the reason and how to eliminat...
DMA buffer Question
I am trying to send large streams of data into the STM32H753 and I'm trying to maximize the baud rate, ideally aiming for a baud rate of 921600. Unfortunately, I don't know the byte size that will be incoming, which makes it difficult to know how to...
Resolved! How to made a function to call other functions?
Hi to all!!!I do repeteadly this function:switch(segundero_d){case 0: numero_0(); break;case 1: numero_1(); break;case 2: numero_2(); break;case 3: numero_3(); break;case 4: numero_4(); break;case 5: numero_5(); break;case 6: numero_6(); break;case 7...
Systick only runs when CPU is active
I've got a strange situation. I've enabled systick, but it doesn't keep time unless the CPU is active. Key excerpts:main.c: SysTickInit(sys_clocks.SYSCLK_Frequency);void SysTickInit(unsigned base_freq) { SysTick->CTRL = 0; // Turn it off. ...
Resolved! Code changes needed for drop in replacement of MCU's with more flash
Say, I have a STM32L431RB (128k,64k) on a board design. This is the lowest flash size on the 6 chips on the STM32L4x1Rx 64pin variety. It certainty looks like I can drop-in any of the larger flash/ram chips as the pin outs all look the same. But do I...
STM32H7 HAL_Delay(200); Problem
This is my first time working with STM32H7B3IIT6 MCU. I wanted to make a led blink application, but the program is HAL_Delay(); it goes into an infinite loop and doesn't exit.
Resolved! LSE Drive
Hi,I have questions about LSE Drive (STM32L0).1) In RCC register are LSEDRV[1:0] bits and I am not sure if I understand it corretly.From datasheet about these bits: They are cleared by a power-on reset or an RTC reset. Once “00�? has been written, th...
Resolved! SRAM2 is only partially retained
Hello dear STM32-Community,I'm using an STM32L4R and wanted to configure my data retention of SRAM2 for standbymode.I did the following changes to the linker file:/* Highest address of the user mode stack */ _estack = 0x10004000; /* end of RAM */ ...
