stm32 with 8 uarts and a small footprint
I'm searching for a stm32 with 8 uarts for io-link. But there is no way I can search for peripherals. So any suggestions, preferably in LQFP-48 or something similar small.Thanks.

I may have encountered a bug in SDMMC_GetCmdResp1 function.
Hello!I have a trouble with Timout delay in SDMMC_GetCmdResp1. I invoke HAL_SD_Init from freertos task. Now SD card isn't connected to board. Timout deleay take approximately 30 seconds, but Timout is 5000 ms.static uint32_t SDMMC_GetCmdResp1(SDMMC_T...
STM32L412RB Option Bytes configuration error in debugging session (perhaps HAL call bug)
Hi,I'm trying to replicate the Hands-on Flash memory Technical training for the STM32L4 (https://www.youtube.com/watch?v=ZMtsR0nZjt4) but i'm having some issues when changing the BOR level and specially in the debugging. The instruction "HAL_FLASH_...
Resolved! STM32L011K4 ADC input never reach 0. Always ADC_GetValue=64 or more
Hi community I'm using Nucleo-L011K4 board ADC to read analog level. Adjusting analog input to any value different that 0 works flawlessly but when I adjust input level to something <50mV ADC_GetValue return a digital value of 64 even if I wire ADC i...
Simultaneous I2C DMA transfer
I need to control 16 RGB addressable LEDs (48 channels). The only drivers which fit my needs are 24 channel I2C drivers (unfortunately, I couldn't find any suiting SPI drivers ), so I need to use two of them. Since both LED banks will create a common...
STM32G070CB UCPD Pins pull-down
HiI am having quite a strange problem with the STM32G070CB.A couple of months ago I start the development of a new product using the STM32G070CB and was having some issue with some pins, and even open up a thread in the forum.https://community.st.com...
STM32F103 is not fast enough
Hello,Here is my code,#include <stdio.h> #include <string.h> void GPIOSYS(void){ GPIO_InitTypeDef GPIOSt; RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO,ENABLE); //GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable,ENABLE); GPIO_PinRemapConfig(GPIO...
Resolved! STM32F407 Datasheet section 2.2 Device overview, Figure 5 shows AHB1 in grey filled and some peripherals too filled grey, along with that.
What does the grey filling indicate. Couldn't find any legend/detail covering this.I initially though it is the part connected to POR/VBAT circuit.. but doesn't look so.Attached image of the page.
Working Code ported from STM32H753 revision Y to revision V not working
We came across a situation where an application code which is working for STM32H753 revision Y when moved to same MCU's revision V does not even go to the main.cpp.Sometimes if it manages to go to main.cpp it writes to I2C1 some values consistently ...
STM32F777 HAL SDMMC
Hi.Im experiencing a race condition in SDMMC_CmdReadSingleBlock. (being called trough HAL_SD_ReadBlocks_DMA).SDMMC_CmdReadSingleBlock calls SDMMC_SendCommand in order to start transfer.Then it calls SDMMC_GetCmdResp1 to verify that transfer is starte...
