Problem configuring DMA on STM32F130rb trying to read a temp sensor
Hi all,I'm trying to write a small program that will read the values from the temperature/humidity sensor. I will try to explain in detail what I have at the moment, but bear with me, I'm still a beginner in bare metal development.I am using an STM32...
Hello, I am working on the stm32f373C8T6 MCU and trying to get some values out of the SDADC but I don't get any values apart from 0 and sometimes 5209/5217 for some reason. I am following the datasheet's instructions that I will display below.
Initialization 1. As prerequisite, fill in the HAL_SDADC_MspInit() : Enable SDADCx clock interface with __SDADCx_CLK_ENABLE(). Configure SDADCx clock divider with HAL_RCCEx_PeriphCLKConfig. Enable power on SDADC with HAL_PWREx_EnableSDADC(). Enable ...
STM32F446RE ADC Tripple injected simultaneous mode triggerd by Timer 1
Hello,i want to use the STM32F446RE MC to controll a PMSM. For that reason I need to measure 2-3 currents simultaneously.I'm working with CubeMX used for the initialization and Keil for the further programming.Also i am mainly using the HAL functions...
Can I operate SD card on STM32F030F4P6 via SPI interface ?
Someone have suggest ?
Regression from RDP level 1 to 0
Hello,I'm trying to test RDP levels configuration on STM32H753.Here is the code I've tested (on a Nucleo 743 with STM32CubeIDE):int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_USART3_UART_Init(); OBInit.Banks = F...
STM32F407 I2C2 busy bit stuck high after configuration
Hi,Saw this (popular) issue on the Q&A and also found many google result regarding this issue, but none of them solve my issue.I'm trying to configured I2C2 bus to work with eeprom.During the configuration, right after setting the I2C RCC clock, the ...
I2C Communication in STM 32 f401 RE
Hi I have omron D6t 32x32 thermal sensor and it give 1023 field of data , How to receive more than 1 byte data in stm? Can any one help me? Also I am storing the value to an character array but i need the value in decimal how to obatin that?
ADC: dual ADC mode interleved mode vs. one signal connected to 2 ADCs
Hello,my intention is to catch a 'thin spike' from the input analog signal. Therefore I wish the sample times from 2 ADCs may cover echo other's conversion time, so that the thin spike will not be missed.My plan is to use 8.5 cycles for sampling and ...
Resolved! Need clarifications on CSS of STM32H7
Hello,I don't understand the description of the Clock Security System in the Ref Manual of STM32H7 (section 7.5.3).First question is : what exactly is the CSS doing ? (what kind of control is done on the clock). What is a definition of "a failure of...
