I am having trouble getting the ADC to work right in basic polled operation. I am polling two channels which provide voltages via resistor dividers. I have measured the voltages at the ADC inputs and they are correct so I do not believe the divider i...
STM32H7B Workshop 2020 MOOCUnzip full codePage 49 of Lab PDF• Unzip the STM32H7B3Workshop2020_modified_files.7z tothe C:\2020_ST_GFX_WS\STM32H7BWorkshop2020• It will overwrite the existing files with the implementation for all labs withinpre-processo...
In RM0091, A.7.2 ADC enable sequence code example:ADC1->ISR |= ADC_CR_ADRDY; /* (2) */However, there is no ADC_CR_ADRDY, it is supposed to be ADC_ISR_ADRDY.Also, examples should not show the bad practice using RMW to clear rc_w1 status bits, so this ...
One user mentions noise from USBhttps://community.st.com/s/question/0D50X00009XkfMDSAZ/stm32f4-adc-noise-with-increased-activity-in-usb-fsOther comments:Keep the wiring short, and make sure the resistor value matches the ADC input impedance. I’ve suc...
I have been using STM32G MCUs with USB PD Sink or Source application. Right now, I want to implement Debug Accessory Mode in either STM32G0 or G4 MCUs with SInk USB PD Application. Hence, i would like to use USB-C cable SBU and Data lines for MCU fla...
I am a newbie here. I have purchased a STM32G071 Nucleo-64 development board. I wish to interface it to the 5 volts signal(s). The intended interface pins are PB1, PB3 and PB4. The Absolute Maximum ratings VIN states:- 1) Input voltage on FT_xx pins ...
I am using two different STM23 microcontrollers using 2 MCP2551 in between. However, the CAN Communication is not working between STM32F4-Discovery board and stm32f091cct6 microcontroller. For the testing purpose, I have check the CAN communication b...
I want to let STM32L552CC into sleep mode.I add HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI);Build is OK,but when Debug ,the error appeared, Why?
Hello, I will take place at the training at the 25th and own already the board.Thanks for providing this workshop!Best regards
My target is select more slaves in callback I2C RX , I have tryed withvoid HAL_I2C_MasterRxCpltCallback(I2C_HandleTypeDef *hi2c){ if (hi2c1.Instance->CR2 & I2C_CR2_SADD == I2C_ADDRESS) {.....}}but don't work !!When I try to use the field in static ...
