I'm working on a STM32L072, and I want to implement an update over the air. I saw there is an errata about the dual bank boot, and ST has made a workaround on it, and it uses the EEPROM.Code from the errata sheet:void SystemInit(void) { /* ...
In CubeMX 5.3.0 I have configured FATFS and FREERTOS for a card running STM32L431. The HAL SDMMC driver is communicating with SD card, and everything goes well until the FATFS want to read the MBR block from the SD card. In this case, the DMA channel...
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...
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...
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...
Hi,I'm looking for the right steps to add the Hal library to a Keil project.i already have the stm32f1xx hal library that include the hal and the cmsis folders (src and include).i'm facing some problem with linking the library. so if someone can tell...
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. ...
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...
