I2C Timeout Problem
Hi!I'm using mpu6050 and Nucleo-f103RB without MXCUBEi got problem with I2C communication.LED is blink in infinity../* Wait until SB flag is set */ if(I2C_WaitOnFlagUntilTimeout(hi2c, I2C_FLAG_SB, RESET, Timeout, tickstart) != HAL_OK) { return...
Problem with a timer counter.
I set a timer to count 500us ticksTIM_InitStruct.Prescaler = (uint16_t)40000-1; //SYSCLK = 80Mhz – 80Mhz/40000 = 500us TIM_InitStruct.CounterMode = LL_TIM_COUNTERMODE_UP; TIM_InitStruct.Autoreload = 0xFFFFFFFF; //TIM2 – 32-bit c...
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...
